【问题描述】：

我有一个自定义 Jenkins master 的 Dockerfile，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 build 命令期间安装 docker build --no-cache -t jenkins .

但是 install-plugins.sh 无法安装插件

【问题讨论】：

你可以访问这个地址https://updates.jenkins.io/download/plugins/structs-plugin/1.5/structs-plugin.hpi吗？
是的。插件 URL 不正确。正确的 URL 是 https://updates.jenkins.io/download/plugins/structs/1.5/structs.hpi，但现在得到不同的错误 [/usr/share/jenkins/ref/plugins/plugins/copyartifact.jpi] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive.
您需要确保在构建 docker 镜像时可以访问互联网。这意味着请检查代理出站连接是否正常。
确保您的代理允许连接

标签： docker jenkins jenkins-docker

【解决方案1】：

我使用你的 Dockerfile 来构建镜像，没有代理，它工作正常。我使用了一些在您的输出中编写的插件。所以，你的 Dockerfile 没问题，这个问题可能是代理。

这很容易评估。在下载带/不带代理的插件时尝试构建这个/另一个图像。
