Jenkins-on-Vagrant-with-Docker-Slaves

Prerequisites

1. Vagrant

Optional (but is really recommended)

1. vagrant-lxc plugin: vagrant plugin install vagrant-lxc
2. vagrant-lxc related configuration on Host. See https://github.com/fgrehm/vagrant-lxc/wiki

Getting started

$ git clone git@github.com:rrader/docker-jenkins-slave.git djs
$ cd djs
$ ./djs.sh up
[lots of vagrant output ....]
==================================================
Jenkins should be available on 10.0.3.74:8080
Start using slaves with adding one
 e.g. # ./djs.sh add centos7-java Luke

Now you should be able to use your just deployed jenkins on http://10.0.3.74:8080 or similar

Now let's add some slaves with ./djs.sh add <image> <name>

$ ./djs.sh add centos7-java Luke
Unable to find image 'antigluk/jenkins-slave-centos6-java' locally
Pulling repository antigluk/jenkins-slave-centos6-java
[lots of docker output ....]
Status: Downloaded newer image for antigluk/jenkins-slave-centos6-java:latest
507e2a18674253d0d7d1f5201ee963681704c2d18310af619f9fcbb0124efaf3
Connection to 10.0.3.74 closed.

This will pull centos7-java image from Docker Hub and start it. After this command ends you should be able to see Luke worker in "Build Executor Status" section on Jenkins.

Notes [important]

Only centos6-java and centos7-java are ready to use now with Vagrant Jenkins

docker-jenkins-slave [DEPRECATED]

This section describes how to build and use slaves without Vagrant, as it were in version 1.x.

CentOS 5, 6, Suse12 and Debian Jenkins slaves based on Docker

Install

1. Clone this repository
2. Install Swarm Plugin to your Jenkins
3. Go to subfolder of desired slave OS (centos5, squeeze etc)
4. Do $ sudo bash build.sh

Usage

1. Go to subfolder of desired slave OS (centos5, squeeze etc), again
2. Do $ sudo bash add_slave.sh SlaveName (it assumes that docker machine sees host as 172.17.42.1)
3. In Jenkins now you should see new slave, modify or create new job and specify tag docker-<tagname> (see list of tagnames on wiki)
