# k8s-master installer 사용법
|
||||
|
||||
## 구성 요소 및 버전
|
||||
|
||||
## Prerequisites
|
||||
* 해당 installer는 폐쇄망 기준 가이드입니다.
|
||||
* OS 설치 및 package repo를 아래 가이드에 맞춰 설치합니다.
|
||||
* https://github.com/tmax-cloud/hypercloud-install-guide/tree/master/Package#os-%EC%84%A4%EC%B9%98--package-repo-%EA%B5%AC%EC%B6%95-%EA%B0%80%EC%9D%B4%EB%93%9C
|
||||
* image registry를 아래 가이드에 맞춰 구축합니다.
|
||||
* https://github.com/tmax-cloud/hypercloud-install-guide/tree/master/Image_Registry#image-registry-%EC%84%A4%EC%B9%98-%EA%B0%80%EC%9D%B4%EB%93%9C
|
||||
* image registry에 이미지를 push 합니다.
|
||||
* https://github.com/tmax-cloud/hypercloud-install-guide/tree/master/K8S_Master#%ED%8F%90%EC%87%84%EB%A7%9D-%EC%84%A4%EC%B9%98-%EA%B0%80%EC%9D%B4%EB%93%9C
|
||||
|
||||
## 폐쇄망 설치 가이드
|
||||
|
||||
## Step0. k8s.config 설정
|
||||
* 목적 : `k8s 설치 진행을 위한 k8s config 설정`
|
||||
* 순서 :
|
||||
* 환경에 맞는 config 내용을 작성합니다.
|
||||
* imageRegistry={IP}:{PORT}
|
||||
* ex : imageRegistry=172.22.5.2:5000
|
||||
* crioVersion={crio version}
|
||||
* ex : crioVersion=1.17
|
||||
* k8sVersion={kubernetes version}
|
||||
* ex : k8sVersion=1.17.6
|
||||
* apiServer={kubernetes API server ip}
|
||||
* ex : apiServer=172.21.7.2
|
||||
* podSubnet={POD_IP_POOL}/{CIDR}
|
||||
* ex : podSubnet=10.244.0.0/16
|
||||
|
||||
## Step1. installer 실행
|
||||
* 목적 : `k8s 설치 진행을 위한 shell script 실행`
|
||||
* 순서 :
|
||||
```bash
|
||||
sudo ./k8s_infra_installer.sh up
|
||||
```
|
||||
* 비고 :
|
||||
* k8s.config, k8s_infra_installer.sh파일과 yaml 디렉토리는 같은 디렉토리 내에에 있어야 합니다.
