Our Goal is:

Creating a Jenkins Pipeline which will provision several EC2 instances using terraform and then installing Docker on the EC2 instances using Ansible

What we need:

1. Jenkins master server on AWS
2. Two Jenkins Agent (slaves)
   • Must have git, terraform, and ansible installed
   • Must have appropriate IAM instance profile attached
3. Jenkins pipeline job

What we have on this Repo:

1. Terraform: Under the infra-using-terraform folder we have terraform code, which will provision multiple EC2 instances on AWS. Note: EC2 instances will be provisioned from Ubuntu AMI and Amazon linux2 AMI. Which represents different linux distributions.
2. Ansible playbook: We have three ansible-playbook.
   • docker_install_on_ubuntu.yaml
   • docker_install_on_amazon_linux.yaml
   • docker_installation_playbook.yaml for calling appropriate playbook as per linux distro.
3. Jenkinsfile which will be used to configure Jenkins pipeline job.

About Jenkinsfile

Our pipeline will use two jenkins slaves. One is labeled as common and another one is ansible. On the common labeled slave all the stages will be built, and for running ansible-playbook we will use ansible labeled slave.
