Rails Ansible

Note: Storing secret in plaintext in playbook isn't a good practice, I have written this originally for absolute beginner to DevOps. If you are using this on production, I would advise look into using secrets management, like Ansible vault : https://docs.ansible.com/ansible/latest/user_guide/vault.html

Here's an introductory guide on using ansible vault

To encrypt your environment vars, you can use the ansible-vault encrypt command like this :
ansible-vault encrypt vars/envs.yml vars/vars.yml

You can view the content of the encrypted files like this :
ansible-vault view vars/envs.yml vars/vars.yml

When running playbook with encrypted file, you need to provide the password you used to encrypt the file. You can use --ask-vault-pass to supply the vault password at runtime, a prompt will appear for you input the password.
ansible-playbook server-provision.yml --ask-vault-pass
