Jenkins Docker in Docker(dind)

This example can be used to create a Docker image using the Jenkins build automation system. , having:

• Jenkins
• docker
• How to add docker host and client

To try the example, you need to have a docker installed on your OS. And needed sudoers account permission[1]

After docker installation, execute this command to bake a docker image in a terminal:

build.sh

Let's make sure that the build is normally done.:

docker images

To run docker, excute this command in a ternimal:

docker run -d --name jenkins -p 8080:8080 -p 50000:50000 --privileged -v /jenkins_dind_home:/var/jenkins_home  -v /var/run/docker.sock:/var/run/docker.sock modenaf360/jenkins-dind:latest

If want set TimeZone

docker run -d --name jenkins -p 8080:8080 -p 50000:50000 --privileged -v /jenkins_dind_home:/var/jenkins_home  -v /var/run/docker.sock:/var/run/docker.sock -e TZ=Asia/Seoul modenaf360/jenkins-dind:latest

Check rest index call :

http://localhost:8080

If you want to get into docker container os, excute this command [2] :

docker exec -i -t jenkins /bin/bash

And let's check if the docker command is called well in the docker container. :

docker images
