jenkins plugins installed via CLI inside docker container is not showing up in jenkins web console

According to the README.md file in the official JenkinsCI for Docker repository, I have started a jenkins master in a docker container with a named volume such as this

$ docker run -d \
--publish 8080:8080 \
--volume jenkins_home:/var/jenkins_home \
--name jenkins_master \
jenkins

After that, I have used the browser to:

All worked fine.

Later i tried to install some jenkins plugins via CLI (instead of the web console) like the following

$ docker exec -it jenkins_master /bin/bash
$ install-plugins.sh hockeyapp

It shows that everything installed correctly. However, when i visit localhost:8080 via the browser, i see that the hockeyapp plugin was not installed.

How can i make sure that plugins are available from the web console, while I install them from docker exec CLI?

Noteworthy, i found that there are 2 different plugins folder. One where hockeyapp is available. One where hockeyapp is not available.

$ ls /usr/share/jenkins/ref/plugins/ # shows hockeyapp
$ ls /var/jenkins_home/plugins/      # does not show hockeyapp
Solution

  • The install-plugins.sh is designed for pre-installing plugins.

    Plugins that you install in that way will be picked up when the container starts, from the /usr/share/jenkins/ref/plugins/ directory that you mentioned.

    Try restarting (or stopping and then starting) the container again. After that you should see the newly installed plugins appear correctly in the web console.
