以编程方式获取容器在Kubernetes中所属的Pod的名称吗?

问题描述

是否有一种方法可以通过编程方式获取Kubernetes中容器所属的Pod的名称?如果可以，怎么办?我正在使用fabric8的Java客户端，但是curl或类似的东西也可以.

Is there a way to programmatically get the name of the pod that a container belongs to in Kubernetes? If so how? I'm using fabric8's java client but curl or something similar will be fine as well.

请注意，自那以后，我不想使用特定的标签来查找容器(我假设)，如果使用复制控制器进行缩放，我可能不会总是找到正确的容器.

Note that I don't want to find the pod using a specific label since then (I assume) I may not always find the right pod if it's scaled with a replication controller.

推荐答案

您可以使用向下API .

例如:

apiVersion: v1
kind: Pod
metadata:
  name: dapi-test-pod
spec:
  containers:
    - name: test-container
      image: gcr.io/google_containers/busybox
      command: [ "/bin/sh", "-c", "env" ]
      env:
        - name: MY_POD_NAME
          valueFrom:
            fieldRef:
              fieldPath: metadata.name
        - name: MY_POD_NAMESPACE
          valueFrom:
            fieldRef:
              fieldPath: metadata.namespace
        - name: MY_POD_IP
          valueFrom:
            fieldRef:
              fieldPath: status.podIP
  restartPolicy: Never
