Web site deployment project (Advanced LINUX)

Use terraform to initialize a server, then deploy a web app with its database and API using ansible tool. This server is supposed to be secure (proper user permissions and fw deployed) and monitored by prometheus.

1. Setup venv for ansible

   ./bin/setup.sh
   source .venv/bin/activate

2. Install ansible dependencies

   ansible-galaxy install -r requirements.yml 
   # fix pymongo error du to python 3.12.x 
   ./bin/fix_mongodb_role.sh

3. Initialize a server using terraform

   Choice between Digital Ocean droplet and local Multipass VM (default) by changing the TF_VAR_CLOUD boolean in ./terraform/env.sh

   # Loads `TF_VAR_CLOUD` and `TF_VAR_DIGITALOCEAN_TOKEN` (get it from your digitalocean profile)
   source ./terraform/env.sh
   # Install dependencies
   terraform -chdir=./terraform init
   # Deploy the vm/droplet and generate the "hosts" ansible file
   terraform -chdir=./terraform apply -auto-approve
   # Teardown
   terraform -chdir=./terraform destroy -auto-approve

   SSH connection

   ssh ubuntu@$(terraform -chdir=./terraform output -raw frontend_ip) -i ./terraform/id_rsa

4. Run Ansible playbook to deploy the web app, api and install requirements

   ansible-playbook -i ./inventory playbooks/main.yml
