# AWS ALB Ingress Controller
|
||||
|
||||
**NOTE:** The current image version is `v1.1.6`. Please file any issues you find and note the version used.
|
||||
|
||||
The AWS ALB Ingress Controller satisfies Kubernetes [ingress resources](https://kubernetes.io/docs/user-guide/ingress) by provisioning [Application Load Balancers](https://docs.aws.amazon.com/elasticloadbalancing/latest/application/introduction.html).
|
||||
|
||||
This project was originated by [Ticketmaster](https://github.com/ticketmaster) and [CoreOS](https://github.com/coreos) as part of Ticketmaster's move to AWS and CoreOS Tectonic. Learn more about Ticketmaster's Kubernetes initiative from Justin Dean's video at [Tectonic Summit](https://www.youtube.com/watch?v=wqXVKneP0Hg).
|
||||
|
||||
This project was donated to Kubernetes SIG-AWS to allow AWS, CoreOS, Ticketmaster and other SIG-AWS contributors to officially maintain the project. SIG-AWS reached this consensus on June 1, 2018.

## Prerequisite Generic Deployment Command
|
||||
|
||||
!!! attention
|
||||
The default configuration watches Ingress object from *all the namespaces*.
|
||||
To change this behavior use the flag `--watch-namespace` to limit the scope to a particular namespace.
|
||||
|
||||
!!! warning
|
||||
If multiple Ingresses define different paths for the same host, the ingress controller will merge the definitions.
|
||||
|
||||
!!! attention
|
||||
If you're using GKE you need to initialize your user as a cluster-admin with the following command:
|
||||
|
||||
```console
|
||||
kubectl create clusterrolebinding cluster-admin-binding \
|
||||
--clusterrole cluster-admin \
|
||||
--user $(gcloud config get-value account)
|
||||
```
|
||||
|
||||
The following **Mandatory Command** is required for all deployments except for AWS. See below for the AWS version.
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.40.2/deploy/static/provider/cloud/deploy.yaml
|
||||
```
|
||||
|
||||
### Provider Specific Steps
|
||||
|
||||
There are cloud provider specific yaml files.
|
||||
|
||||
#### Docker for Mac
|
||||
|
||||
Kubernetes is available in Docker for Mac (from [version 18.06.0-ce](https://docs.docker.com/docker-for-mac/release-notes/#stable-releases-of-2018))
|
||||
|
||||
First you need to [enable kubernetes](https://docs.docker.com/docker-for-mac/#kubernetes).
|
||||
|
||||
Then you have to create a service:
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
|
||||
```
|
||||
|
||||
#### minikube
|
||||
|
||||
For standard usage:
|
||||
|
||||
```console
|
||||
minikube addons enable ingress
|
||||
```
|
||||
|
||||
For development:
|
||||
|
||||
1. Disable the ingress addon:
|
||||
|
||||
```console
|
||||
minikube addons disable ingress
|
||||
```
|
||||
|
||||
1. Execute `make dev-env`
|
||||
1. Confirm the `nginx-ingress-controller` deployment exists:
|
||||
|
||||
```console
|
||||
$ kubectl get pods -n ingress-nginx
|
||||
NAME READY STATUS RESTARTS AGE
|
||||
default-http-backend-66b447d9cf-rrlf9 1/1 Running 0 12s
|
||||
nginx-ingress-controller-fdcdcd6dd-vvpgs 1/1 Running 0 11s
|
||||
```
|
||||
|
||||
#### AWS
|
||||
|
||||
In AWS we use an Elastic Load Balancer (ELB) to expose the NGINX Ingress controller behind a Service of `Type=LoadBalancer`.
|
||||
Since Kubernetes v1.9.0 it is possible to use a classic load balancer (ELB) or network load balancer (NLB)
|
||||
Please check the [elastic load balancing AWS details page](https://aws.amazon.com/elasticloadbalancing/details/)
|
||||
|
||||
##### Elastic Load Balancer - ELB
|
||||
|
||||
This setup requires to choose in which layer (L4 or L7) we want to configure the Load Balancer:
|
||||
|
||||
- [Layer 4](https://en.wikipedia.org/wiki/OSI_model#Layer_4:_Transport_Layer): Use an Network Load Balancer (NLB) with TCP as the listener protocol for ports 80 and 443.
|
||||
- [Layer 7](https://en.wikipedia.org/wiki/OSI_model#Layer_7:_Application_Layer): Use an Elastic Load Balancer (ELB) with HTTP as the listener protocol for port 80 and terminate TLS in the ELB
|
||||
|
||||
For L4:
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/deploy.yaml
|
||||
```
|
||||
|
||||
For L7:
|
||||
|
||||
Change the value of `service.beta.kubernetes.io/aws-load-balancer-ssl-cert` in the file `provider/aws/deploy-tls-termination.yaml` replacing the dummy id with a valid one. The dummy value is `"arn:aws:acm:us-west-2:XXXXXXXX:certificate/XXXXXX-XXXXXXX-XXXXXXX-XXXXXXXX"`
|
||||
|
||||
Check that no change is necessary with regards to the ELB idle timeout. In some scenarios, users may want to modify the ELB idle timeout, so please check the [ELB Idle Timeouts section](#elb-idle-timeouts) for additional information. If a change is required, users will need to update the value of `service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout` in `provider/aws/deploy-tls-termination.yaml`
|
||||
|
||||
Then execute:
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/deploy-tls-termination.yaml
|
||||
```
|
||||
|
||||
This example creates an ELB with just two listeners, one in port 80 and another in port 443
|
||||
|
||||
|
||||
|
||||
##### ELB Idle Timeouts
|
||||
|
||||
In some scenarios users will need to modify the value of the ELB idle timeout.
|
||||
Users need to ensure the idle timeout is less than the [keepalive_timeout](http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout) that is configured for NGINX.
|
||||
By default NGINX `keepalive_timeout` is set to `75s`.
|
||||
|
||||
The default ELB idle timeout will work for most scenarios, unless the NGINX [keepalive_timeout](http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout) has been modified,
|
||||
in which case `service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout` will need to be modified to ensure it is less than the `keepalive_timeout` the user has configured.
|
||||
|
||||
_Please Note: An idle timeout of `3600s` is recommended when using WebSockets._
|
||||
|
||||
More information with regards to idle timeouts for your Load Balancer can be found in the [official AWS documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/config-idle-timeout.html).
|
||||
|
||||
##### Network Load Balancer (NLB)
|
||||
|
||||
This type of load balancer is supported since v1.10.0 as an ALPHA feature.
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/service-nlb.yaml
|
||||
```
|
||||
|
||||
#### GCE-GKE
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
|
||||
```
|
||||
|
||||
**Important Note:** proxy protocol is not supported in GCE/GKE
|
||||
|
||||
#### Azure
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
|
||||
```
|
||||
|
||||
#### Bare-metal
|
||||
|
||||
Using [NodePort](https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport):
|
||||
|
||||
```console
|
||||
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/baremetal/service-nodeport.yaml
|
||||
```
|
||||
|
||||
!!! tip
|
||||
For extended notes regarding deployments on bare-metal, see [Bare-metal considerations](./baremetal.md).
|
||||
|
||||
### Verify installation
|
||||
|
||||
To check if the ingress controller pods have started, run the following command:
|
||||
|
||||
```console
|
||||
kubectl get pods --all-namespaces -l app.kubernetes.io/name=ingress-nginx --watch
|
||||
```
|
||||
|
||||
Once the operator pods are running, you can cancel the above command by typing `Ctrl+C`.
|
||||
Now, you are ready to create your first ingress.
|
||||
|
||||
### Detect installed version
|
||||
|
||||
To detect which version of the ingress controller is running, exec into the pod and run `nginx-ingress-controller version` command.
|
||||
|
||||
```console
|
||||
POD_NAMESPACE=ingress-nginx
|
||||
POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app.kubernetes.io/component=controller -o jsonpath='{.items[0].metadata.name}')
|
||||
|
||||
kubectl exec -it $POD_NAME -n $POD_NAMESPACE -- /nginx-ingress-controller --version
|
||||
```
|
||||
|
||||
## Using Helm
|
||||
|
||||
NGINX Ingress controller can be installed via [Helm](https://helm.sh/) using the chart [ingress-nginx/ingress-nginx](https://kubernetes.github.io/ingress-nginx).
|
||||
Official documentation is [here](https://kubernetes.github.io/ingress-nginx/deploy/#using-helm)
|
||||
|
||||
To install the chart with the release name `my-nginx`:
|
||||
|
||||
```console
|
||||
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
|
||||
helm install my-nginx ingress-nginx/ingress-nginx
|
||||
```
|
||||
|
||||
Detect installed version:
|
||||
|
||||
```console
|
||||
POD_NAME=$(kubectl get pods -l app.kubernetes.io/name=ingress-nginx -o jsonpath='{.items[0].metadata.name}')
|
||||
kubectl exec -it $POD_NAME -- /nginx-ingress-controller --version
|
||||
```
