Jenkins GIG Deployment

This is a PoC for installing Jenkins using GIG Solutions.

I base the ansible code on Larry's solution (https://github.com/mrlesmithjr/ansible-jenkins) on what jenkins relate with some changes to it. I am also adding a iptable role as I would like to add some extra security to this setup (the latest is not relevant for the Docker build).

There are 2 different proposed solutions:

• ansible_vm.py
• ays_vm.py

These PoC includes:

• Testing through Travis
• Testing (ports) within the jenkins ansible role.

ansible_vm.py

The "base image" Selected for this Build is an "Ubuntu 16.04 x64". It hasn't been tested on any other distribution at the present.

Also NOTE this a a deployment for an Intranet, so you need the OpenVPN against your Cloud Space open for your deployment.

Requirements

You need the following:

• python3
• Ansible
• sshpass
• Python Libraries: * pexpect * jinja2

Instructions

• From your session just execute file ansible_vm.py against the GIG and python along with Ansible will do the rest!

You got 2 set of variables:

• ansible at vars/main.yml
• python: python_variables.txt at the root directory.

ays_run.py

This script has been written to perform an AYS deployment.

This script has to be run in an environment with got all the JS9/AYS9 tools an libraries in it.

At the present it relies on the VM newly created to have a PUBLIC IP for the purposes of the Jenkins installation.

Requirements

You need the following:

• python3
• Ansible
• sshpass
• Python Libraries:
• pexpect
• jinja2

Also, at the presentm you need a GIG Development environment in place and to have the G9 container built. (otherwise you can setup your environment in a different way...)

• https://github.com/Jumpscale/developer/blob/master/README.md
• https://github.com/Jumpscale/ays9/

This script will deploy 2 templates:

• create_vm.yaml
• vars/main.yml

The location for the templates is the following:

• templates/create_vm.yaml_tpl
• templates/main.yaml_tpl

This script also assumes you got a VDC already defined.

Instructions

• From your session just execute file ays_run.py against the GIG and python along with Ansible will do the rest!

The variables are in the following files:

• python_variables.txt
• vars/main_head.yml (these variables are for jenkins and they also need to be completed)

Further Details

Taking into account some security aspects, the Password Based VM will be modified so

• the Password for the default user will be disabled
• the sshd server will be restarted after NOT allowing Passworded Logins
• Your local ssh key will be placed in the server (read vars/main.yml file), so you can log into the VM with the following command:

ssh -i <private_ssh_key> cloudscalers@<_private_ip_>

Jenkins is by default running at port 8080

http://private_ip:8080
