# The Ansible Edda

Ansible playbooks for provisioning The Nine Worlds.

## Secrets vault

- Encrypt with: ```ansible-vault encrypt secrets.yml```
- Decrypt with: ```ansible-vault decrypt secrets.yml```
- Print secrets to STDOUT: ```ansible-vault decrypt --output - secrets.yml```
- Run a playbook with ```ansible-playbook --vault-id @prompt playbook.yml```

## Main

The main entrypoint for The Nine Worlds is [`main.yml`](main.yml).

### Production and testing

The inventory files are split into [`production`](production) and [`testing`](testing).

To run the `main.yml` play on production hosts:
``` sh
ansible-playbook main.yml -i production
```

To run the `main.yml` play on production hosts:
``` sh
ansible-playbook main.yml -i testing
```

### Roles

The plays are composed of roles defined in [`plays/roles`](plays/roles).

To play only a specific role, e.g. `system_base`, run:

``` sh
ansible-playbook --tags "role:system_base"
```

### Role sub-tasks

Some roles are split into smaller groups of tasks. This can be checked by looking at the
`tasks/main.yml` file of a role, e.g.
[`plays/roles/system_base/tasks/main.yml`](plays/roles/system_base/tasks/main.yml).

To play only a particular group within a role, e.g. `sshd` in `system_base`, run:

``` sh
ansible-playbook --tags "role:system_base:sshd"
```
