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 标签中向 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"]

但是好像不行.命令标签中发送多条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

一个容器中只能有一个入口点...如果你想运行多个这样的命令，让 bash 成为入口点，并让所有其他命令是 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/"]
