vagrant-ansible-jenkins

Deployment of Jenkins on a VirtualBox Ubuntu VM using Vagrant and an Ansible playbook.

This is an example of a Vagrant VM deployment (with enabling root ssh and password), and ansible playbook in order to install Jenkins on a VM. This can be modify in order to run some Jenkins labs locally or be extended to test other distribution / playbooks.

This example is based on the example Jenkins CI of the book Ansible For DevOps by Jeff Geerling. I modified the example to:

• make it work on MacOS
• Enable root login via SSH (root/root)
• dissociate Vagrant provisioning and Ansible playbook, so the ansible-playbook can be as close as possible as production playbooks.

Tested with the following versions:

• Ansible 2.10.5
• Vagrant 2.2.7
• VirtualBox 6.0.12
• macOS Catalina 10.15.7

Prerequisite:

• Ansible
• Ansible galaxy
• Vagrant
• VirtualBox

Installation:

ansible-galaxy install -r requirements.yml
vagrant up
ansible-playbook -i inventory.yml provision.yml

We should have the Jenkins GUI available when visiting http://192.168.76.76:8080

We can then log in using the username/password: admin/admin

Jenkins job

We can then create a job that will run the main.yml ansible-playbook locally on the Jenkins server. Example:

1. New Item > Enter the name of the item > Freestyle project > OK
2. Under Build Environment, select Color ANSI Console Output
3. Under Build > Add build step > Execute shell. Add the following:

# Force Ansible to output jobs with color. 
export ANSIBLE_FORCE_COLOR=true
# Run the local test playbook. 
ansible-playbook /opt/ansible-for-devops/main.yml

4. Save
5. Build Now
6. Under Build History, by clicking to the blue icon, we should have the following output:

Started by user admin
Running as SYSTEM
Building in workspace /var/lib/jenkins/workspace/toto
[toto] $ /bin/sh -xe /tmp/jenkins1301434655789940856.sh
+ export ANSIBLE_FORCE_COLOR=true
+ ansible-playbook /opt/ansible-for-devops/main.yml
[WARNING]: provided hosts list is empty, only localhost is available. Note that
the implicit localhost does not match 'all'
