Provision a 3-tier-application with terraform, consisting of a PostGreSQL Database, two nginx webservers and a load balancer. Also provide additional infrastructure, including a keyvault, and Ansible Host and a Bastion Host. Then configure the Webservers using Ansible. This includes OS updates, OS hardening, creating a user and adding a Telegraf agent to collect nginx metrics.

• go the dev or prod environment
• configure the main to your preference or use the standard config matching the above displayed use case
• run terraform commands:
  • terraform init
  • terraform plan
  • terraform apply
• run ansible playbook: (pass the stage variable matching the stage you chose for step 1)
  • ansible-playbook playbook.yaml -i inventory_azure_rm.yaml

• when running the project with remote state file, configure via azure.conf and provider.tf
• pipeline can be imported and started directly via Azure Devops
• Run inital_setup.yml first to setup TF state file and a keyvault. Add the Service Principal credentials to the keyvault (required for Ansible). Change the keyvault name as it needs to be unique over all azure accounts.
• Next run build-pipeline.yml for the Terraform infrastructure and finally ansible-setup.yml for the Nginx Setup via Ansible.
• Destroy all with the destory-pipeline.yml
