Simple Vagrant Master/Slave Initial Setup

This is meant to initialize (2) virgin jenkins servers in a master/slave setup running on the default CentOS7 vagrant boxes. Useful for lab testing, learning or whatever. It will install Jenkins latest, openjdk 1.8, python3/pip, awscli,

Setup Instructions

1. Modify the VagrantFile if needed
2. 'vagrant up' to start the boxes and complete initial provisioning
3. To complete the slave node addition to the master, manually exchange keys

• On the master ('jenkins') - copy generated public key:

vi /var/lib/jenkins/.ssh/id_rsa.pub

• On the slave ('jenkins-slave'), paste the key into authorized_keys

vi /var/lib/jenkins-slave/.ssh/authorized_keys

TODO - update this to use ssh copy key, this is hacky!!

NOTE: Both boxes use the default vagrant logins (vagrant/vagrant). Both servers have a 'jenkins' user with no password set. You can sudo/su to the 'jenkins' user as needed.

Further Jenkins master setup for a decent lab (if desired):

1. gain access via the default admin pwd; finish setup with default plugins
2. create your admin user
3. switch to matrix security
4. give admin user all rights in the matrix
5. add a restricted dev user
6. give this restricted user the following permissions: OVERALL: read CREDENTIALS: NONE AGENT: NONE JOB: build,cancel,configure,discover,read, workspace (maybe give create...) RUN: update VIEW: configure, create, read SCM: NONE
7. Additional Plugins:
   • Amazon EC2 plugin
8. Attach the slave node (user is 'jenkins' and slave server = 'jenkins-slave')
