在 jenkins docker 映像中安装插件失败

Question

我有一个 Dockerfile 用于自定义 Jenkins 主控，如下所示：

FROM jenkins/jenkins:lts
USER root
ENV http_proxy http://xx.xx.xx.xx:8080
ENV https_proxy http://xx.xx.xx.xx:8080
RUN apt-get update
RUN apt-get install -y --allow-unauthenticated ldap-utils curl wget vim nano sudo git
RUN adduser jenkins sudo
User jenkins
ENV http_proxy http://xx.xx.xx.xx:8080
ENV https_proxy http://xx.xx.xx.xx:8080
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN  /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt
RUN echo 2.176.2 > /usr/share/jenkins/ref/jenkins.install.UpgradeWizard.state
RUN echo 2.176.2 > /usr/share/jenkins/ref/jenkins.install.InstallUtil.lastExecVersion
EXPOSE 9081
EXPOSE 50000

我预计插件将在 docker 构建命令docker build --no-cache -t jenkins.

但是 install-plugins.sh 无法安装插件

Answer 1

我用你的 Dockerfile 来构建图像，没有代理，它工作正常。 我使用了一些在您的 output 中编写的插件。 所以，你的 Dockerfile 很好，这个问题可能是代理。

这可以很容易地评估。 在下载带/不带代理的插件时尝试构建这个/另一个图像。

Answer 2

您需要确保在构建 docker 映像时可以访问 Internet。 这意味着请检查代理出站连接是否正常。
