Installation

  • Kubernetes API를 호출하는데 사용할 Target Minion에 아래와 같이 Package를 설치합니다.

  • root 권한에서 작업합니다.

kubernetes 설치

  • Kubernetes API Python Bindings

    $ pip3 install kubernetes

Configuring K8s KUBERNETESMOD

salt-minion config에 추가할 내용은 다음과 같다.
아래 中, kubernetes.kubeconfig와 kubernetes.kubeconfig-data 둘 중 하나만 설정하면 된다.
만일 둘 다 설정되어 있다면, kubernetes.kubeconfig를 우선한다.

단, kubernetes.kubeconfig로 설정하였을 경우는, k8s Control plane node에 salt-minion설치 및 설정되어야 하는 경우만 해당된다.(로컬 파일에 접근해야 하기 때문)

원격 노드에서 k8s api를 사용해야 하는 경우는 kubernetes.kubeconfig-data를 사용하도록 한다.

위의 이유로 CH에서는 kubernetes.kubeconfig-data를 사용하는 방법을 표준으로 채택한다.

kubernetes.kubeconfig: '/root/.kube/config'
kubernetes.kubeconfig-data: '<base64 encoded "/root/.kube/config" content>'
kubernetes.context: '<context name inside ~/.kube/config>'

kubernetes.kubeconfig-data 설정 방법은 다음과 같다.

먼저 kubeconfig 파일 내용을 base64로 one line encoding한다.

$ cat ~/.kube/config | base64 | tr -d '\n'
