jpcaparas/jenkinsci-webapp repository overview

⁠Jenkins CI for web apps

⁠Overview

Before anything else, what is Jenkins⁠? Here's a good answer from a Quora question asking when and why it's used⁠:

This is a Docker build that contains essential libraries for testing & building web applications on the Jenkins project configuration dialog:

• PHP 5.6
• Composer
• MariaDB 10
• node.js 7

These packages can be then be invoked as build steps using their respective binaries:

⁠System requirements

1. Docker running on your machine.
2. At least 1GB RAM.

⁠Running the Docker image as a container

1. Run docker run -d -p 8000:8080 -p 50000:50000 -v [dir-on-host-machine]:/var/jenkins_home jpcaparas/jenkinsci-webapp.
   • The -d flag runs it on detached mode (in the background).
   • The -p flag sets port mappings between host and container.
   • The -v flag sets volume bindings between host and container. This means that files & folders on dir-on-host-machine directory (which is mapped to /var/jenkins_home on the container, containing Jenkins data), will not be wiped when the container is stopped or rebuilt, preserving configuration, plugins, build data, etc.
   • jpcaparas/jenkinsci-webapp is the image hosted on Docker Hub⁠.
   • Make sure dir-on-host-machine is writable by the jenkins user and group.
2. Go to http://[hostname]:8000 and follow installation steps.

⁠Resources

1. This build is based off of the Official Jenkins Docker build⁠.
2. The official reference⁠ for the docker run command has plenty of options.
