我想在中为我的redis容器启用密码 minikube . 所以，我启用了 requirepass 在 redis.conf . 然后，我用这个配置文件生成docker映像 Dockerfile .

FROM redis
COPY --chown=redis:redis redis.conf /usr/local/etc/redis/redis.conf
CMD ["redis-server", "/usr/local/etc/redis/redis.conf"]

然后，我使用下面的命令启动一个带有这个图像的pod Deployment 亚马尔。

kind: Deployment
apiVersion: apps/v1
metadata:
  name: cache
  labels:
    run: cache
spec:
  replicas: 1
  selector:
    matchLabels:
      run: cache
  template:
    metadata:
      labels:
        run: cache
    spec:
      containers:
        - name: cache
          image: redis
          envFrom:
            - configMapRef: 
                name: redis-cfgmap
          resources:
            limits:
              memory: "256Mi"
              cpu: "200m"
          imagePullPolicy: Never
      restartPolicy: Always
      terminationGracePeriodSeconds: 30

注意，我正在做一个 docker build -t redis:latest 从一个空壳里跑出来 eval $(minikube docker-env) . 也， imagePullPolicy 设置为 Never 以便从本地dokcer注册表中提取图像。
虽然pod确实出现了，但是日志中提到，没有使用指定的配置文件。
