问题描述

我有一个名为"jenkins-app-2843651954-4zqdp"的吊舱.我想在此Pod上临时安装一些软件.我该怎么办?

I have one pod running with name 'jenkins-app-2843651954-4zqdp'. I want to install few softwares temporarily on this pod. How can I do this?

我正在尝试-kubectl exec -it jenkins-app-2843651954-4zqdp -- /bin/bash 然后运行apt-get install命令，但是由于我所访问的用户没有sudo访问权限，所以我无法运行命令

I am trying this- kubectl exec -it jenkins-app-2843651954-4zqdp -- /bin/bash and then running apt-get install commands but since the user I am accessing with doesn't have sudo access I am not able to run commands

推荐答案

• 使用kubectl describe pod ...查找运行Pod的节点和容器ID(docker://...)
• SSH进入节点
• 运行docker exec -u root ID -- /bin/bash
• Use kubectl describe pod ... to find the node running your Pod and the container ID (docker://...)
• SSH into the node
• run docker exec -u root ID -- /bin/bash
