docker - 有什么方法可以在非root docker容器中创建可写卷？

Question

我已经从 Jenkins (Jenkins)官方Docker集线器中提取了一张图片。

但是我创建的容器没有root权限。

我无法更改容器内共享量中的任何内容

这是我正在运行的命令

docker run -itd -v /home/user/docker:/home/host -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

有什么办法可以使该路径“/ home / host”在容器中可写？

Answer 1

Jenkins docker的用法包括:

NOTE: Avoid using a bind mount from a folder on the host machine into /var/jenkins_home, as this might result in file permission issues (the user used inside the container might not have rights to the folder on the host machine).

If you really need to bind mount jenkins_home, ensure that the directory on the host is accessible by the jenkins user inside the container (jenkins user - uid 1000) or use -u some_other_user parameter with docker run.

docker run -d -u aKnownUser -v jenkins_home:/var/jenkins_home -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

另一种方法是让docker创建一个命名卷:

docker run -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins:lts
