# Apache Druid
[Apache Druid](https://druid.apache.org/) is a high performance real-time analytics database.
## Dependency Update
Before you install the Druid Chart, update the dependencies :
```bash
helm dependency update helm/druid
```
## Install Chart
To install the Druid Chart into your Kubernetes cluster :
```bash
helm install druid helm/druid --namespace dev --create-namespace
```
After installation succeeds, you can get a status of Chart
```bash
helm status druid -n dev
```
If you want to delete your Chart, use this command:
```bash
helm uninstall druid -n dev
```
### Helm ingresses
The Chart provides ingress configuration to allow customization the installation by adapting
the `values.yaml` depending on your setup.
Please read the comments in the `values.yaml` file for more details on how to configure your reverse
proxy or load balancer.
### Chart Prefix
This Helm automatically prefixes all names using the release name to avoid collisions.
### URL prefix
This chart exposes 6 endpoints:
- Druid Overlord
- Druid Broker
- Druid Coordinator
- Druid Historical
- Druid Middle Manager
- Druid Router
### Druid configuration
Druid configuration can be changed by using environment variables from Docker image.
See the
[Druid Docker entry point](https://github.com/apache/druid/blob/master/distribution/docker/druid.sh)
for more informations
### Middle Manager and Historical Statefulset
Middle Managers and Historicals uses StatefulSet. Persistence is enabled by default.

# MySQL
[MySQL](https://MySQL.org) is one of the most popular database servers in the world. Notable users include Wikipedia, Facebook and Google.
## Introduction
This chart bootstraps a single node MySQL deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
## Prerequisites
- Kubernetes 1.10+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```bash
$ helm install --name my-release stable/mysql
```
The command deploys MySQL on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
By default a random password will be generated for the root user. If you'd like to set your own password change the mysqlRootPassword
in the values.yaml.
You can retrieve your root password by running the following command. Make sure to replace [YOUR_RELEASE_NAME]:
printf $(printf '\%o' `kubectl get secret [YOUR_RELEASE_NAME]-mysql -o jsonpath="{.data.mysql-root-password[*]}"`)
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```bash
$ helm delete --purge my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release completely.
## Configuration
The following table lists the configurable parameters of the MySQL chart and their default values.

Some of the parameters above map to the env variables defined in the [MySQL DockerHub image](https://hub.docker.com/_/mysql/).
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install --name my-release \
--set mysqlRootPassword=secretpassword,mysqlUser=my-user,mysqlPassword=my-password,mysqlDatabase=my-database \
stable/mysql
```
The above command sets the MySQL `root` account password to `secretpassword`. Additionally it creates a standard database user named `my-user`, with the password `my-password`, who has access to a database named `my-database`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install --name my-release -f values.yaml stable/mysql
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Persistence
The [MySQL](https://hub.docker.com/_/mysql/) image stores the MySQL data and configurations at the `/var/lib/mysql` path of the container.
By default a PersistentVolumeClaim is created and mounted into that directory. In order to disable this functionality
you can change the values.yaml to disable persistence and use an emptyDir instead.
> *"An emptyDir volume is first created when a Pod is assigned to a Node, and exists as long as that Pod is running on that node. When a Pod is removed from a node for any reason, the data in the emptyDir is deleted forever."*
**Notice**: You may need to increase the value of `livenessProbe.initialDelaySeconds` when enabling persistence by using PersistentVolumeClaim from PersistentVolume with varying properties. Since its IO performance has impact on the database initialization performance. The default limit for database initialization is `60` seconds (`livenessProbe.initialDelaySeconds` + `livenessProbe.periodSeconds` * `livenessProbe.failureThreshold`). Once such initialization process takes more time than this limit, kubelet will restart the database container, which will interrupt database initialization then causing persisent data in an unusable state.
## Custom MySQL configuration files
The [MySQL](https://hub.docker.com/_/mysql/) image accepts custom configuration files at the path `/etc/mysql/conf.d`. If you want to use a customized MySQL configuration, you can create your alternative configuration files by passing the file contents on the `configurationFiles` attribute. Note that according to the MySQL documentation only files ending with `.cnf` are loaded.
```yaml
configurationFiles:
mysql.cnf: |-
[mysqld]
skip-host-cache
skip-name-resolve
sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
mysql_custom.cnf: |-
[mysqld]
```
## MySQL initialization files
The [MySQL](https://hub.docker.com/_/mysql/) image accepts *.sh, *.sql and *.sql.gz files at the path `/docker-entrypoint-initdb.d`.
These files are being run exactly once for container initialization and ignored on following container restarts.
If you want to use initialization scripts, you can create initialization files by passing the file contents on the `initializationFiles` attribute.
```yaml
initializationFiles:
first-db.sql: |-
CREATE DATABASE IF NOT EXISTS first DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
second-db.sql: |-
CREATE DATABASE IF NOT EXISTS second DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
```
## SSL
This chart supports configuring MySQL to use [encrypted connections](https://dev.mysql.com/doc/refman/5.7/en/encrypted-connections.html) with TLS/SSL certificates provided by the user. This is accomplished by storing the required Certificate Authority file, the server public key certificate, and the server private key as a Kubernetes secret. The SSL options for this chart support the following use cases:
* Manage certificate secrets with helm
* Manage certificate secrets outside of helm
## Manage certificate secrets with helm
Include your certificate data in the `ssl.certificates` section. For example:
```
ssl:
enabled: false
secret: mysql-ssl-certs
certificates:
- name: mysql-ssl-certs
ca: |-
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
cert: |-
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
key: |-
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
```
> **Note**: Make sure your certificate data has the correct formatting in the values file.
## Manage certificate secrets outside of helm
1. Ensure the certificate secret exist before installation of this chart.
2. Set the name of the certificate secret in `ssl.secret`.
3. Make sure there are no entries underneath `ssl.certificates`.
To manually create the certificate secret from local files you can execute:
```
kubectl create secret generic mysql-ssl-certs \
--from-file=ca.pem=./ssl/certificate-authority.pem \
--from-file=server-cert.pem=./ssl/server-public-key.pem \
--from-file=server-key.pem=./ssl/server-private-key.pem
```
> **Note**: `ca.pem`, `server-cert.pem`, and `server-key.pem` **must** be used as the key names in this generic secret.
If you are using a certificate your configurationFiles must include the three ssl lines under [mysqld]
```
[mysqld]
ssl-ca=/ssl/ca.pem
ssl-cert=/ssl/server-cert.pem
ssl-key=/ssl/server-key.pem
```

# PostgreSQL
[PostgreSQL](https://www.postgresql.org/) is an object-relational database management system (ORDBMS) with an emphasis on extensibility and on standards-compliance.
For HA, please see [this repo](https://github.com/bitnami/charts/tree/master/bitnami/postgresql-ha)
## This Helm chart is deprecated
Given the [`stable` deprecation timeline](https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained PostgreSQL Helm chart is now located at [bitnami/charts](https://github.com/bitnami/charts/).
The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/<chart> # Helm 3
$ helm install --name my-release bitnami/<chart> # Helm 2
```
To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm upgrade my-release bitnami/<chart>
```
Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in [this issue](https://github.com/helm/charts/issues/20969) created as a common place for discussion.
## TL;DR;
```console
$ helm install my-release stable/postgresql
```
## Introduction
This chart bootstraps a [PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).
## Prerequisites
- Kubernetes 1.12+
- Helm 2.11+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install my-release stable/postgresql
```
The command deploys PostgreSQL on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
## Parameters
The following tables lists the configurable parameters of the PostgreSQL chart and their default values.
| Parameter | Description | Default |

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install my-release \
--set postgresqlPassword=secretpassword,postgresqlDatabase=my-database \
stable/postgresql
```
The above command sets the PostgreSQL `postgres` account password to `secretpassword`. Additionally it creates a database named `my-database`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```console
$ helm install my-release -f values.yaml stable/postgresql
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Production configuration and horizontal scaling
This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`. You can use this file instead of the default one.
- Enable replication:
```diff
- replication.enabled: false
+ replication.enabled: true
```
- Number of slaves replicas:
```diff
- replication.slaveReplicas: 1
+ replication.slaveReplicas: 2
```
- Set synchronous commit mode:
```diff
- replication.synchronousCommit: "off"
+ replication.synchronousCommit: "on"
```
- Number of replicas that will have synchronous replication:
```diff
- replication.numSynchronousReplicas: 0
+ replication.numSynchronousReplicas: 1
```
- Start a prometheus exporter:
```diff
- metrics.enabled: false
+ metrics.enabled: true
```
To horizontally scale this chart, you can use the `--replicas` flag to modify the number of nodes in your PostgreSQL deployment. Also you can use the `values-production.yaml` file or modify the parameters shown above.
### Change PostgreSQL version
To modify the PostgreSQL version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/postgresql/tags/) using the `image.tag` parameter. For example, `image.tag=12.0.0`
### postgresql.conf / pg_hba.conf files as configMap
This helm chart also supports to customize the whole configuration file.
Add your custom file to "files/postgresql.conf" in your working directory. This file will be mounted as configMap to the containers and it will be used for configuring the PostgreSQL server.
Alternatively, you can specify PostgreSQL configuration parameters using the `postgresqlConfiguration` parameter as a dict, using camelCase, e.g. {"sharedBuffers": "500MB"}.
In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the `configurationConfigMap` parameter. Note that this will override the two previous options.
### Allow settings to be loaded from files other than the default `postgresql.conf`
If you don't want to provide the whole PostgreSQL configuration file and only specify certain parameters, you can add your extended `.conf` files to "files/conf.d/" in your working directory.
Those files will be mounted as configMap to the containers adding/overwriting the default configuration using the `include_dir` directive that allows settings to be loaded from files other than the default `postgresql.conf`.
Alternatively, you can also set an external ConfigMap with all the extra configuration files. This is done by setting the `extendedConfConfigMap` parameter. Note that this will override the previous option.
### Initialize a fresh instance
The [Bitnami PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, they must be located inside the chart folder `files/docker-entrypoint-initdb.d` so they can be consumed as a ConfigMap.
Alternatively, you can specify custom scripts using the `initdbScripts` parameter as dict.
In addition to these options, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the `initdbScriptsConfigMap` parameter. Note that this will override the two previous options. If your initialization scripts contain sensitive information such as credentials or passwords, you can use the `initdbScriptsSecret` parameter.
The allowed extensions are `.sh`, `.sql` and `.sql.gz`.
### Sidecars
If you need additional containers to run within the same pod as PostgreSQL (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.
```yaml
# For the PostgreSQL master
master:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234
# For the PostgreSQL replicas
slave:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234
```
### Metrics
The chart optionally can start a metrics exporter for [prometheus](https://prometheus.io). The metrics endpoint (port 9187) is not exposed and it is expected that the metrics are collected from inside the k8s cluster using something similar as the described in the [example Prometheus scrape configuration](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml).
The exporter allows to create custom metrics from additional SQL queries. See the Chart's `values.yaml` for an example and consult the [exporters documentation](https://github.com/wrouesnel/postgres_exporter#adding-new-metrics-via-a-config-file) for more details.
### Use of global variables
In more complex scenarios, we may have the following tree of dependencies
```
+--------------+
| |
+------------+ Chart 1 +-----------+
| | | |
| --------+------+ |
| | |
| | |
| | |
| | |
v v v
+-------+------+ +--------+------+ +--------+------+
| | | | | |
| PostgreSQL | | Sub-chart 1 | | Sub-chart 2 |
| | | | | |
+--------------+ +---------------+ +---------------+
```
The three charts below depend on the parent chart Chart 1. However, subcharts 1 and 2 may need to connect to PostgreSQL as well. In order to do so, subcharts 1 and 2 need to know the PostgreSQL credentials, so one option for deploying could be deploy Chart 1 with the following parameters:
```
postgresql.postgresqlPassword=testtest
subchart1.postgresql.postgresqlPassword=testtest
subchart2.postgresql.postgresqlPassword=testtest
postgresql.postgresqlDatabase=db1
subchart1.postgresql.postgresqlDatabase=db1
subchart2.postgresql.postgresqlDatabase=db1
```
If the number of dependent sub-charts increases, installing the chart with parameters can become increasingly difficult. An alternative would be to set the credentials using global variables as follows:
```
global.postgresql.postgresqlPassword=testtest
global.postgresql.postgresqlDatabase=db1
```
This way, the credentials will be available in all of the subcharts.
## Persistence
The [Bitnami PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) image stores the PostgreSQL data and configurations at the `/bitnami/postgresql` path of the container.
Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
If you already have data in it, you will fail to sync to standby nodes for all commits, details can refer to [code](https://github.com/bitnami/bitnami-docker-postgresql/blob/8725fe1d7d30ebe8d9a16e9175d05f7ad9260c93/9.6/debian-9/rootfs/libpostgresql.sh#L518-L556). If you need to use those data, please covert them to sql and import after `helm install` finished.
## NetworkPolicy
To enable network policy for PostgreSQL, install [a networking plugin that implements the Kubernetes NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin), and set `networkPolicy.enabled` to `true`.
For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting the DefaultDeny namespace annotation. Note: this will enforce policy for _all_ pods in the namespace:
```console
$ kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```
With NetworkPolicy enabled, traffic will be limited to just port 5432.
For more precise policy, set `networkPolicy.allowExternal=false`. This will only allow pods with the generated client label to connect to PostgreSQL.
This label will be displayed in the output of a successful install.
## Differences between Bitnami PostgreSQL image and [Docker Official](https://hub.docker.com/_/postgres) image
- The Docker Official PostgreSQL image does not support replication. If you pass any replication environment variable, this would be ignored. The only environment variables supported by the Docker Official image are POSTGRES_USER, POSTGRES_DB, POSTGRES_PASSWORD, POSTGRES_INITDB_ARGS, POSTGRES_INITDB_WALDIR and PGDATA. All the remaining environment variables are specific to the Bitnami PostgreSQL image.
- The Bitnami PostgreSQL image is non-root by default. This requires that you run the pod with `securityContext` and updates the permissions of the volume with an `initContainer`. A key benefit of this configuration is that the pod follows security best practices and is prepared to run on Kubernetes distributions with hard security constraints like OpenShift.
- For OpenShift, one may either define the runAsUser and fsGroup accordingly, or try this more dynamic option: volumePermissions.securityContext.runAsUser="auto",securityContext.enabled=false,shmVolume.chmod.enabled=false
### Deploy chart using Docker Official PostgreSQL Image
From chart version 4.0.0, it is possible to use this chart with the Docker Official PostgreSQL image.
Besides specifying the new Docker repository and tag, it is important to modify the PostgreSQL data directory and volume mount point. Basically, the PostgreSQL data dir cannot be the mount point directly, it has to be a subdirectory.
```
helm install postgres \
--set image.repository=postgres \
--set image.tag=10.6 \
--set postgresqlDataDir=/data/pgdata \
--set persistence.mountPath=/data/ \
stable/postgresql
```
## Upgrade
It's necessary to specify the existing passwords while performing an upgrade to ensure the secrets are not updated with invalid randomly generated passwords. Remember to specify the existing values of the `postgresqlPassword` and `replication.password` parameters when upgrading the chart:
```bash
$ helm upgrade my-release stable/postgresql \
--set postgresqlPassword=[POSTGRESQL_PASSWORD] \
--set replication.password=[REPLICATION_PASSWORD]
```
> Note: you need to substitute the placeholders _[POSTGRESQL_PASSWORD]_, and _[REPLICATION_PASSWORD]_ with the values obtained from instructions in the installation notes.
## 8.0.0
Prefixes the port names with their protocols to comply with Istio conventions.
If you depend on the port names in your setup, make sure to update them to reflect this change.
## 7.1.0
Adds support for LDAP configuration.
## 7.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pull/17281 the `apiVersion` of the statefulset resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.
This major version bump signifies this change.
## 6.5.7
In this version, the chart will use PostgreSQL with the Postgis extension included. The version used with Postgresql version 10, 11 and 12 is Postgis 2.5. It has been compiled with the following dependencies:
- protobuf
- protobuf-c
- json-c
- geos
- proj
## 5.0.0
In this version, the **chart is using PostgreSQL 11 instead of PostgreSQL 10**. You can find the main difference and notable changes in the following links: [https://www.postgresql.org/about/news/1894/](https://www.postgresql.org/about/news/1894/) and [https://www.postgresql.org/about/featurematrix/](https://www.postgresql.org/about/featurematrix/).
For major releases of PostgreSQL, the internal data storage format is subject to change, thus complicating upgrades, you can see some errors like the following one in the logs:
```bash

[1] FATAL: database files are incompatible with server
[1] DETAIL: The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 11.3.
```
In this case, you should migrate the data from the old chart to the new one following an approach similar to that described in [this section](https://www.postgresql.org/docs/current/upgrading.html#UPGRADING-VIA-PGDUMPALL) from the official documentation. Basically, create a database dump in the old chart, move and restore it in the new one.
### 4.0.0
This chart will use by default the Bitnami PostgreSQL container starting from version `10.7.0-r68`. This version moves the initialization logic from node.js to bash. This new version of the chart requires setting the `POSTGRES_PASSWORD` in the slaves as well, in order to properly configure the `pg_hba.conf` file. Users from previous versions of the chart are advised to upgrade immediately.
IMPORTANT: If you do not want to upgrade the chart version then make sure you use the `10.7.0-r68` version of the container. Otherwise, you will get this error
```
The POSTGRESQL_PASSWORD environment variable is empty or not set. Set the environment variable ALLOW_EMPTY_PASSWORD=yes to allow the container to be started with blank passwords. This is recommended only for development
```
### 3.0.0
This releases make it possible to specify different nodeSelector, affinity and tolerations for master and slave pods.
It also fixes an issue with `postgresql.master.fullname` helper template not obeying fullnameOverride.
#### Breaking changes
- `affinty` has been renamed to `master.affinity` and `slave.affinity`.
- `tolerations` has been renamed to `master.tolerations` and `slave.tolerations`.
- `nodeSelector` has been renamed to `master.nodeSelector` and `slave.nodeSelector`.
### 2.0.0
In order to upgrade from the `0.X.X` branch to `1.X.X`, you should follow the below steps:
- Obtain the service name (`SERVICE_NAME`) and password (`OLD_PASSWORD`) of the existing postgresql chart. You can find the instructions to obtain the password in the NOTES.txt, the service name can be obtained by running
```console
$ kubectl get svc
```
- Install (not upgrade) the new version
```console
$ helm repo update
$ helm install my-release stable/postgresql
```
- Connect to the new pod (you can obtain the name by running `kubectl get pods`):
```console
$ kubectl exec -it NAME bash
```
- Once logged in, create a dump file from the previous database using `pg_dump`, for that we should connect to the previous postgresql chart:
```console
$ pg_dump -h SERVICE_NAME -U postgres DATABASE_NAME > /tmp/backup.sql
```
After run above command you should be prompted for a password, this password is the previous chart password (`OLD_PASSWORD`).
This operation could take some time depending on the database size.
- Once you have the backup file, you can restore it with a command like the one below:
```console
$ psql -U postgres DATABASE_NAME < /tmp/backup.sql
```
In this case, you are accessing to the local postgresql, so the password should be the new one (you can find it in NOTES.txt).
If you want to restore the database and the database schema does not exist, it is necessary to first follow the steps described below.
```console
$ psql -U postgres
postgres=# drop database DATABASE_NAME;
postgres=# create database DATABASE_NAME;
postgres=# create user USER_NAME;
postgres=# alter role USER_NAME with password 'BITNAMI_USER_PASSWORD';
postgres=# grant all privileges on database DATABASE_NAME to USER_NAME;
postgres=# alter database DATABASE_NAME owner to USER_NAME;
```

These files will be injected as a config maps and add/overwrite the default configuration using the `include_dir` directive that allows settings to be loaded from files other than the default `postgresql.conf`.

This Helm chart is deprecated
Given the `stable` deprecation timeline (https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained Helm chart is now located at bitnami/charts (https://github.com/bitnami/charts/).
The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/<chart> # Helm 3
$ helm install --name my-release bitnami/<chart> # Helm 2
```
To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm upgrade my-release bitnami/<chart>
```
Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in this issue (https://github.com/helm/charts/issues/20969) created as a common place for discussion.
** Please be patient while the chart is being deployed **
PostgreSQL can be accessed via port {{ template "postgresql.port" . }} on the following DNS name from within your cluster:
{{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local - Read/Write connection
{{- if .Values.replication.enabled }}
{{ template "postgresql.fullname" . }}-read.{{ .Release.Namespace }}.svc.cluster.local - Read only connection
{{- end }}
{{- if and .Values.postgresqlPostgresPassword (not (eq .Values.postgresqlUsername "postgres")) }}
To get the password for "postgres" run:
export POSTGRES_ADMIN_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-postgres-password}" | base64 --decode)
{{- end }}
To get the password for "{{ template "postgresql.username" . }}" run:
export POSTGRES_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-password}" | base64 --decode)
To connect to your database run the following command:
kubectl run {{ template "postgresql.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ .Release.Namespace }} --image {{ template "postgresql.image" . }} --env="PGPASSWORD=$POSTGRES_PASSWORD" {{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
--labels="{{ template "postgresql.fullname" . }}-client=true" {{- end }} --command -- psql --host {{ template "postgresql.fullname" . }} -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }} -p {{ template "postgresql.port" . }}
{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
Note: Since NetworkPolicy is enabled, only pods with label {{ template "postgresql.fullname" . }}-client=true" will be able to connect to this PostgreSQL cluster.
{{- end }}
To connect to your database from outside the cluster execute the following commands:
{{- if contains "NodePort" .Values.service.type }}
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "postgresql.fullname" . }})
{{ if (include "postgresql.password" . ) }}PGPASSWORD="$POSTGRES_PASSWORD" {{ end }}psql --host $NODE_IP --port $NODE_PORT -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }}
{{- else if contains "LoadBalancer" .Values.service.type }}
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "postgresql.fullname" . }}'
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "postgresql.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")
{{ if (include "postgresql.password" . ) }}PGPASSWORD="$POSTGRES_PASSWORD" {{ end }}psql --host $SERVICE_IP --port {{ template "postgresql.port" . }} -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }}
{{- else if contains "ClusterIP" .Values.service.type }}
kubectl port-forward --namespace {{ .Release.Namespace }} svc/{{ template "postgresql.fullname" . }} {{ template "postgresql.port" . }}:{{ template "postgresql.port" . }} &
{{ if (include "postgresql.password" . ) }}PGPASSWORD="$POSTGRES_PASSWORD" {{ end }}psql --host 127.0.0.1 -U {{ .Values.postgresqlUsername }} -d {{- if .Values.postgresqlDatabase }} {{ .Values.postgresqlDatabase }}{{- else }} postgres{{- end }} -p {{ template "postgresql.port" . }}

# incubator/zookeeper
This helm chart provides an implementation of the ZooKeeper [StatefulSet](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/) found in Kubernetes Contrib [Zookeeper StatefulSet](https://github.com/kubernetes/contrib/tree/master/statefulsets/zookeeper).
## Prerequisites
* Kubernetes 1.10+
* PersistentVolume support on the underlying infrastructure
* A dynamic provisioner for the PersistentVolumes
* A familiarity with [Apache ZooKeeper 3.5.x](https://zookeeper.apache.org/doc/r3.5.5/)
## Chart Components
This chart will do the following:
* Create a fixed size ZooKeeper ensemble using a [StatefulSet](http://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/).
* Create a [PodDisruptionBudget](https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-disruption-budget/) so kubectl drain will respect the Quorum size of the ensemble.
* Create a [Headless Service](https://kubernetes.io/docs/concepts/services-networking/service/) to control the domain of the ZooKeeper ensemble.
* Create a Service configured to connect to the available ZooKeeper instance on the configured client port.
* Optionally apply a [Pod Anti-Affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#inter-pod-affinity-and-anti-affinity-beta-feature) to spread the ZooKeeper ensemble across nodes.
* Optionally start JMX Exporter and Zookeeper Exporter containers inside Zookeeper pods.
* Optionally create a job which creates Zookeeper chroots (e.g. `/kafka1`).
* Optionally create a Prometheus ServiceMonitor for each enabled exporter container
## Installing the Chart
You can install the chart with the release name `zookeeper` as below.
```console
$ helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
$ helm install --name zookeeper incubator/zookeeper
```
If you do not specify a name, helm will select a name for you.
### Installed Components
You can use `kubectl get` to view all of the installed components.
```console{%raw}
$ kubectl get all -l app=zookeeper
NAME: zookeeper

1. `statefulsets/zookeeper` is the StatefulSet created by the chart.
1. `po/zookeeper-<0|1|2>` are the Pods created by the StatefulSet. Each Pod has a single container running a ZooKeeper server.
1. `svc/zookeeper-headless` is the Headless Service used to control the network domain of the ZooKeeper ensemble.
1. `svc/zookeeper` is a Service that can be used by clients to connect to an available ZooKeeper server.
1. `servicemonitor/zookeeper` is a Prometheus ServiceMonitor which scrapes the jmx-exporter metrics endpoint
1. `servicemonitor/zookeeper-exporter` is a Prometheus ServiceMonitor which scrapes the zookeeper-exporter metrics endpoint

You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```console
$ helm install --name my-release -f values.yaml incubator/zookeeper
```
## Default Values
- You can find all user-configurable settings, their defaults and commentary about them in [values.yaml](values.yaml).
## Deep Dive
## Image Details
The image used for this chart is based on Alpine 3.9.0.
## JVM Details
The Java Virtual Machine used for this chart is the OpenJDK JVM 8u192 JRE (headless).
## ZooKeeper Details
The chart defaults to ZooKeeper 3.5 (latest released version).
## Failover
You can test failover by killing the leader. Insert a key:
```console
$ kubectl exec zookeeper-0 -- bin/zkCli.sh create /foo bar;
$ kubectl exec zookeeper-2 -- bin/zkCli.sh get /foo;
```
Watch existing members:
```console
$ kubectl run --attach bbox --image=busybox --restart=Never -- sh -c 'while true; do for i in 0 1 2; do echo zk-${i} $(echo stats | nc <pod-name>-${i}.<headless-service-name>:2181 | grep Mode); sleep 1; done; done';
zk-2 Mode: follower
zk-0 Mode: follower
zk-1 Mode: leader
zk-2 Mode: follower
```
Delete Pods and wait for the StatefulSet controller to bring them back up:
```console
$ kubectl delete po -l app=zookeeper
$ kubectl get po --watch-only
NAME READY STATUS RESTARTS AGE
zookeeper-0 0/1 Running 0 35s
zookeeper-0 1/1 Running 0 50s
zookeeper-1 0/1 Pending 0 0s
zookeeper-1 0/1 Pending 0 0s
zookeeper-1 0/1 ContainerCreating 0 0s
zookeeper-1 0/1 Running 0 19s
zookeeper-1 1/1 Running 0 40s
zookeeper-2 0/1 Pending 0 0s
zookeeper-2 0/1 Pending 0 0s
zookeeper-2 0/1 ContainerCreating 0 0s
zookeeper-2 0/1 Running 0 19s
zookeeper-2 1/1 Running 0 41s
```
Check the previously inserted key:
```console
$ kubectl exec zookeeper-1 -- bin/zkCli.sh get /foo
ionid = 0x354887858e80035, negotiated timeout = 30000
WATCHER::
WatchedEvent state:SyncConnected type:None path:null
bar
```
## Scaling
ZooKeeper can not be safely scaled in versions prior to 3.5.x
## Limitations
* Only supports storage options that have backends for persistent volume claims.

Thank you for installing ZooKeeper on your Kubernetes cluster. More information
about ZooKeeper can be found at https://zookeeper.apache.org/doc/current/
Your connection string should look like:
{{ template "zookeeper.fullname" . }}-0.{{ template "zookeeper.fullname" . }}-headless:{{ .Values.service.ports.client.port }},{{ template "zookeeper.fullname" . }}-1.{{ template "zookeeper.fullname" . }}-headless:{{ .Values.service.ports.client.port }},...
You can also use the client service {{ template "zookeeper.fullname" . }}:{{ .Values.service.ports.client.port }} to connect to an available ZooKeeper server.
