Question

我有以下Dockerfile：

FROM sonarqube

ADD https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/

USER root
RUN  chmod -R 655 /opt/sonarqube/extensions/plugins/ &&  chown -R sonarqube.sonarqube /opt/sonarqube/extensions/plugins/

当我运行图像构建时：

docker run -d -p 9000:9000 sonarqube-test

容器已创建并退出。

默认情况下，root用户是root用户，如果容器使用-it而不是-d，则通过传递/ bin / bash这样的容器来执行：docker run -it sonarqube-test /bin/bash。

该插件已正确复制到目录中，并已为用户sonarqube进行了修改。

有人知道为什么要退出集装箱吗？

Answer 1

添加文件时您已经可以设置用户了：

FROM sonarqube

ADD --chown=sonarqube:sonarqube https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/

我对此进行了测试，并且可以正常工作。

Answer 2

要解决此问题，请添加缺少的执行权限，如下所示：

FROM sonarqube

ADD https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/

USER root
RUN  chmod -R 555 /opt/sonarqube/extensions/plugins/ &&  chown -R sonarqube.sonarqube /opt/sonarqube/extensions/plugins/

Answer 3

如果您有ENTRYPOINT，则在docker-run结束时您的/bin/bash不能与-d一起使用（-it可以正常工作）。

您需要在exec tail -f /dev/null的末尾添加while true; do sleep 1000; done或ENTRYPOINT

exec tail -f /dev/null是最有效的，您可以在此处查看：A flag in docker to always be up

这是具有以下解决方案的码头工人： https://github.com/sequenceiq/hadoop-docker/blob/master/bootstrap.sh

这是一个oficial fedora solution，他们在末尾创建一个CMD ["/bin/bash"]： https://github.com/fedora-cloud/docker-brew-fedora/blob/4dbc2ccd3b4d52258981eaf12043025054d53023/x86_64//Dockerfile

运行后退出容器Docker
