docker - 如何通过 kubernetes pod 传递 docker run 标志

Question

您好，我正在运行我运行 mailhog 容器的 kubernetes 集群。

但我需要使用自己的 docker run 参数来运行它。如果我直接在docker中运行它。我会使用命令:

docker run  mailhog/mailhog -auth-file=./auth.file

但我需要通过 Kubernetes pod 运行它。我的 pod 看起来像:

   apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
      name: mailhog
    spec:
      replicas: 1
      revisionHistoryLimit: 1
      strategy:
          type: RollingUpdate
      template:
        metadata:
          labels:
            app: mailhog
        spec:
          containers:
          - name: mailhog
            image: us.gcr.io/com/mailhog:1.0.0
            ports:
            - containerPort: 8025

如何通过kubernetes实现以-auth-file=./auth.file为参数运行Docker容器。谢谢。

我尝试在 containers

下添加

        command: ["-auth-file", "/data/mailhog/auth.file"]

然后我明白了

 Failed to start container with docker id 7565654 with error: Error response from daemon: Container command '-auth-file' not found or does not exist.

这是我的 deployment.yaml:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: mailhog
spec:
  replicas: 1
  revisionHistoryLimit: 1
  strategy:
      type: RollingUpdate
  template:
    metadata:
      labels:
        app: mailhog
    spec:
      volumes:
      - name: secrets-volume
        secret:
            secretName: mailhog-login
      containers:
      - name: mailhog
        image: us.gcr.io/com/mailhog:1.0.0
        resources:
          limits:
            cpu: 70m
            memory: 30Mi
          requests:
            cpu: 50m
            memory: 20Mi
        volumeMounts:
        - name: secrets-volume
          mountPath: /data/mailhog
          readOnly: true
        ports:
        - containerPort: 8025
        - containerPort: 1025
        args:
          - "-auth-file=/data/mailhog/auth.file"
