在Jenkins Docker镜像中安装插件失败。

Question

我有一个Dockerfile，用于创建一个自定义的Jenkins主节点，内容如下：

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

我期望在docker build命令docker build --no-cache -t jenkins .期间安装插件。

但是install-plugins.sh无法安装插件。

你能访问这个地址吗 https://updates.jenkins.io/download/plugins/structs-plugin/1.5/structs-plugin.hpi？ - Shmuel

插件的 URL 不正确。正确的 URL 是 https://updates.jenkins.io/download/plugins/structs/1.5/structs.hpi，但现在出现了不同的错误：[/usr/share/jenkins/ref/plugins/plugins/copyartifact.jpi] 找不到尾端中央目录签名。这个文件要么不是一个压缩包，要么它是一个多部分归档的一个磁盘。在后一种情况下，中央目录和压缩包注释将在此存档的最后一个磁盘上找到。 - user2439278

在构建 Docker 镜像时，您需要确保可以访问互联网。这意味着请检查代理出站连接是否正常工作。 - maheshs007

请确保您的代理允许连接。 - LinPy

Answer 1

我使用了您的Dockerfile来构建镜像，没有代理，它可以正常工作。我使用了您输出中编写的一些插件。因此，您的Dockerfile没有问题，这个问题可能是代理引起的。

这很容易评估。尝试在使用/不使用代理的情况下下载插件时构建此/另一个镜像。
