将Jenkins插件安装到Docker Jenkins [英] Installing Jenkins Plugins to Docker Jenkins

问题描述

我有以下以jenkins为基础映像的Dockerfile:

I have the following Dockerfile with jenkins as the base image:

FROM jenkins
USER root
ENV JENKINS_MIRROR http://mirrors.jenkins-ci.org
RUN for plugin in git-client git ws-cleanup ; do wget -O $JENKINS_HOME/plugins/${plugin}.hpi $JENKINS_MIRROR/plugins/${plugin}/latest/${plugin}.hpi ; done
EXPOSE 8080

我正在尝试安装一些其他插件，但这给我一个错误，提示no such file or directory

I'm trying to install some additional plugins but it gives me an error saying no such file or directory

然后我开始并连接到此构建步骤的容器，以调试"错误:

I then started and connected to the container of this build step in order to "debug" the error:

但是，我找不到原因，因为每个目录似乎都存在.此外，如果我随后在bash中手动运行for循环，则所有插件均已正确安装...

However, I could not find out the cause because every directory seems to exist. Furthermore, if I then run the for-loop manually in the bash, all plugins are installed correctly...

我进一步注意到，如果按如下所示将其安装在根目录中，则可以安装插件:

I further noticed, that the installation of the the plugins works, if I install them in the root directory as follows:

RUN for plugin in git-client git ws-cleanup ; do wget -O ${plugin}.hpi $JENKINS_MIRROR/plugins/${plugin}/latest/${plugin}.hpi ; done

但是，这是错误的位置，因为它们必须放置在$ JENKINS_HOME/plugins目录中

However, this is the wrong place as they have to be placed in the directory $JENKINS_HOME/plugins

为什么我不能在$JENKINS_HOME/plugins中安装插件?

Why I am not able to install the plugins in $JENKINS_HOME/plugins?

推荐答案

我看不到您的屏幕截图，但您似乎未遵循官方说明.参见 https://github.com/cloudbees/jenkins-ci.org-docker在安装更多工具"下.注意:

I can't read your screenshots, but you don't seem to be following the official instructions. See https://github.com/cloudbees/jenkins-ci.org-docker under "Installing more tools". Note:

• 您应将插件保存到/usr/share/jenkins/ref/plugins
• 您可以改用plugins.txt文件，其中包含插件的名称，并且可以使用提供的plugins.sh脚本进行处理.看起来像:

• You should save the plugins to /usr/share/jenkins/ref/plugins
• You could use a plugins.txt file instead, which contains the names of your plug-ins, and you can process with the provided plugins.sh script. This looks like:

COPY plugins.txt /usr/share/jenkins/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/plugins.txt

我认为您的方法不起作用的原因是与启动脚本中的某些处理有关.

I think the reason your approach wasn't working was to do with some processing in the start-up script.
