This playbook installs the necessary requirements to run a Docker container, configure secrets and launch the app.

After cloning this repo, you'll need to configure hosts (either in /etc/ansible/hosts or by using a file that'll be passed as arguments of the ansible-playbook command with -i).

Then you'll need to create your own vault.yml file in host_vars// with the values:

vault_secret_key_base: <your_secret_key_base>
vault_secret_token: <your_secret_token>

Don't forget to encrypt this file with ansible-vault encrypt if you want to keep it in version control.

You can also set where you want the app repo to be cloned to by changing the value of the app_dir variable in host_vars/<hostname>/vars.yml.

Then simply run:

ansible-playbook site.yml

Don't forget --ask-vault-pass if you have encrypted vault.yml.

I would probably test the app more thoroughly, let it run for some time and check the metrics of the server to see if it sustains and if it still would in a prod envrionment.
