@gakhrejah likely there was a temporary glitch in the update center. CC @olblak

DOCKERFILE

FROM jenkinsci/jenkins:alpine

Just info about who created this

COPY Jenkins-SetInitialState-Completed.groovy /usr/share/jenkins/ref/init.groovy.d/Jenkins-SetInitialState-Completed.groovy

COPY Jenkins-Admin-User-Creation-AtInitial.groovy /usr/share/jenkins/ref/init.groovy.d/Jenkins-Admin-User-Creation-AtInitial.groovy
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN xargs /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

ENV JAVA_OPTS "-Djenkins.install.runSetupWizard=false"

[batmat]

• why did put xargs before /usr/local/bin/install-plugins.sh? I suspect that might be the issue.
• Also you didn't provide the error you were getting in the first place.
• What is the content of plugins.txt please?

There hasn't been any response from @gakhrejah since January. I propose closing this out unless more information is provided about the issue.

Update :

Actually I have the same issue: failing with Could not resolve host: updates.jenkins.io
I don't do anything exotic just following the doc + adding few perm constraints.

COPY --chown=jenkins:jenkins  plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

I suppose the update center is kinda broken (It seems there is a redirection from updates.jenkins.io to mirrors.jenkins.io, but 404 ), because it used to work last week.

Performing a handwritten curl it works so I have any clue why (Same if I copy paste url in my browser)
Really weird.

if anyone has any info, I'll be glad.

Thank you.

I see this in my Ansible task output "stderr": "curl: (6) Could not resolve host: updates.jenkins.io".
