1. 在容器中获取 Pod 的IP

通过环境变量来实现,该环境变量直接引用 resource 的状态字段,示例如下:

apiVersion: v1
kind: ReplicationController
metadata:
  name: world-v2
spec:
  replicas: 3
  selector:
    app: world-v2
  template:
    metadata:
      labels:
        app: world-v2
    spec:
      containers:
      - name: service
        image: test
        env:
        - name: POD_IP
          valueFrom:
            fieldRef:
              fieldPath: status.podIP
        ports:
        - name: service
          containerPort: 777

容器中可以直接使用 POD_IP 环境变量获取容器的 IP。
