Installing Jenkins Plugins to Docker Jenkins

I can't read your screenshots, but you don't seem to be following the official instructions. See https://github.com/cloudbees/jenkins-ci.org-docker under "Installing more tools". Note:

You should save the plugins to /usr/share/jenkins/ref/plugins
You could use a plugins.txt file instead, which contains the names of your plug-ins, and you can process with the provided plugins.sh script. This looks like:

COPY plugins.txt /usr/share/jenkins/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/plugins.txt

I think the reason your approach wasn't working was to do with some processing in the start-up script.

install Jenkins & its plugins in Docker,then save a new image to be used in the other offline PC

One option is to mound local directory wit Jenkins and install plugins.

docker run -it --rm -v $PWD/:/var/jenkins_home -p 8081:8080 jenkins/jenkins

Once you mount host directory, then install required plugging, create Dockerfile like below

FROM jenkins/jenkins
COPY plugins /var/jenkins_home/plugins/

Then build this Dockerfile,

docker build -t my_custom_jenkins .

Then you can share this image with others and it will contain all plugins.

If you need full configuration then use below option

FROM jenkins/jenkins
COPY . /var/jenkins_home/plugins/

Jenkins in Docker Container - installing Plugins manually doesn't work

Apparently restart throught UI somehow doesn't work here. I've restartet jenkins docker container (or docker service) and now I see the installed plugins in the UI.

How to add Jenkins plugins on docker container deployment?

I ended up creating my own image from a Dockerfile in Dev. Then I deployed it to the internet restricted environment.

FROM jenkins/jenkins:lts
# if we want to install via apt
USER root
RUN apt-get update && apt-get install -y ruby make
# drop back to the regular jenkins user - good practice
USER jenkins
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt*

In the plugins.txt file I provided a list of plugins I would like to be installed.

Unable to install suggested plugins of jenkins on docker

I had the same issue when using the latest weekly, so I suggest to use the lts since when specify jenkins in your command you are pulling latest weekly

run your command like this:

docker pull jenkins/jenkins:lts
docker run -p 8080:8080 jenkins/jenkins:lts

see jenkins
