Kubernetes-将多个命令传递给容器 [英] Kubernetes - Passing multiple commands to the container

问题描述

我想在kubernetes配置文件的command标记中向Docker容器发送多个入口点命令.

I want send multiple entrypoint commands to a Docker container in the command tag of kubernetes config file.

apiVersion: v1
kind: Pod
metadata:
  name: hello-world
spec:  # specification of the pod’s contents
  restartPolicy: Never
  containers:
  - name: hello
    image: "ubuntu:14.04"
    command: ["command1 arg1 arg2 && command2 arg3 && command3 arg 4"]

但似乎不起作用.在命令标签中发送多个命令的正确格式是什么?

But it seems like it does not work. What is the correct format of sending multiple commands in the command tag?

推荐答案

容器中只能有一个入口点...如果要运行多个这样的命令，请将bash用作入口点，然后将所有其他命令是bash运行的参数:

There can only be a single entrypoint in a container... if you want to run multiple commands like that, make bash be the entry point, and make all the other commands be an argument for bash to run:

command: ["/bin/bash","-c","touch /foo && echo 'here' && ls /"]
