create a sample directory with mkdir jenkinsci and create a new Dockerfile
cd jenkinsci
touch Dockerfile
FROM jenkins:2.0
USER root
RUN apt-get update \
&& apt-get install -y sudo \
&& rm -rf /var/lib/apt/lists/*
RUN echo “jenkins ALL=NOPASSWD: ALL” >> /etc/sudoersUSER jenkins
COPY plugins.txt /usr/share/jenkins/plugins.txt
RUN /usr/local/bin/plugins.sh /usr/share/jenkins/plugins.txt
then create a plugins.txt file for jenkins plugins
scm-api:latest
git-client:latest
git:latest
greenballs:latest
save it then build the jenkins image
sudo docker build -t jenkinsci .
now we must to run container
sudo docker run -d -v /var/run/docker.sock:/var/run/docker.sock \
-v $(which docker):/usr/bin/docker -p 8080:8080 jenkinsci
by the way we mapped docker socket ,binary for running docker commands in container
this command will return container job id. Dont clear the console!
when you visit the http://localhost:8080 you will see the jenkins default login screen
you can find the administator password with
docker logs <job_id>
———————————————————————————————————————-
Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:
67120601cc394ff697b8a23e30440288
You can continue the next steps then you will see the Jenkins Home screen, then we must the test docker command with docker-test project
- Create a Freestyle Project
- Add shell build step then save it
-
sudo docker run hello-world
- Run the build and look at the build logs
run the build.
Well, you dockerized jenkins 🙂 awesome! In next chapter we will integrate jenkins volume
