Jenkins Docker Image Build

Installation

Build the Jenkins BlueOcean Docker Image

1. docker pull jenkins/jenkins
2. docker build -t myjenkins-blueocean:2.414.2-1 .

You might face some error during the build like (unable to locate package docker-ce-cli) so before proceeding make sure you run the following commands :-

1. sudo apt-get update
2. sudo apt install apt-transport-https ca-certificates curl software-properties-common
3. curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - (This might work as it is deprecated)
4. sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu kinetic stable"

Create the network 'jenkins'

docker network create jenkins

Run the Container

MacOS / Linux

docker run --name jenkins-docker --rm --detach --privileged --network jenkins --network-alias docker --env DOCKER_TLS_CERTDIR=/certs --volume jenkins-docker-certs:/certs/client --volume jenkins-data:/var/jenkins_home --publish 2376:2376 docker:dind --storage-driver overlay2

Windows

docker run
--name jenkins-blueocean
--restart=on-failure
--detach
--network jenkins
--env DOCKER_HOST=tcp://docker:2376
--env DOCKER_CERT_PATH=/certs/client
--env DOCKER_TLS_VERIFY=1
--publish 8080:8080
--publish 50000:50000
--volume jenkins-data:/var/jenkins_home
--volume jenkins-docker-certs:/certs/client:ro
myjenkins-blueocean:2.414.2-1

Get the Password

docker exec jenkins-blueocean cat /var/jenkins_home/secrets/initialAdminPassword

Connect to the Jenkins

https://localhost:8080/

Connect to Jenkins shell

docker exec -it jenkins-blueocean bash -> Non-Root Access

docker exec -it -u 0 {CONTAINER ID} /bin/bash -> Root Access

Python Installation in Jenkins Container

Python Package does not comes with base image of Jenkins so we required to access the Jenkin shell with Root Access to download the Python Package.

Following command is to be executed to gain the root access :-

docker exec -it -u 0 {CONTAINER ID} /bin/bash to open an interactive terminal within the Docker Container as root (user 0).

apt-get update and apt-get install python3 and apt-get install python3-pip to install Python3 and pip within the Docker container.

Pull and run the image alpine/socat

docker run -d --restart=always -p 127.0.0.1:2376:2375 --network jenkins -v /var/run/docker.sock:/var/run/docker.sock alpine/socat tcp-listen:2375,fork,reuseaddr unix-connect:/var/run/docker.sock

docker inspect <contrainer_id>

The above container will be used as a external Docker container for jenkins

docker pull masprtech1/jenkins-agent-python
