有些容器启动时需要通过volume，把配置文件塞进容器的肚子里。本例子中，要把一个README.txt文件添加到容器中。

ConfigMap配置

apiVersion: v1kind: ConfigMapmetadata:  name: playground-configmap  namespace: "playground"data:  readme: |    这是readme文件，请勿删除。复制代码

Pod配置

apiVersion: v1kind: Podmetadata:  name: pod  namespace: "playground"  labels:    app: "playground"spec:  volumes:  - name: configmap-volume    configMap:      name: playground-configmap      items:      - key: "readme"        path: "README.txt"  containers:  - name: "app"    image: "10.211.55.6:5000/yingzhuo/playground:latest"    imagePullPolicy: Always    ports:    - containerPort: 8080    volumeMounts:    - name: configmap-volume      mountPath: "/config"复制代码
