在 jenkins docker 映像中安裝插件失敗

Question

我有一個 Dockerfile 用於自定義 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

我預計插件將在 docker 構建命令docker build --no-cache -t jenkins.

但是 install-plugins.sh 無法安裝插件

Answer 1

我用你的 Dockerfile 來構建圖像，沒有代理，它工作正常。 我使用了一些在您的 output 中編寫的插件。 所以，你的 Dockerfile 很好，這個問題可能是代理。

這可以很容易地評估。 在下載帶/不帶代理的插件時嘗試構建這個/另一個圖像。

Answer 2

您需要確保在構建 docker 映像時可以訪問 Internet。 這意味着請檢查代理出站連接是否正常。
