# Ansible-driven YT-DLP / Airflow Cluster – Quick-Start & Cheat-Sheet
|
||
|
||
> One playbook = one command to **deploy**, **update**, **restart**, or **re-configure** the entire cluster.

|
||
## 0. Prerequisites (run once on the **tower** server)
|
||
|
||
```
|
||
|
||

|
||
|
||
## 1. Ansible Vault Setup (run once on your **local machine**)
|
||
|
||
This project uses Ansible Vault to encrypt sensitive data like passwords and API keys. To run the playbooks, you need to provide the vault password. The recommended way is to create a file named `.vault_pass` in the root of the project directory.
|
||
|
||
1. **Create the Vault Password File:**
|
||
From the project's root directory (e.g., `/opt/yt-ops-services`), create the file. The file should contain only your vault password on a single line.
|
||
|
||
```bash
|
||
# Replace 'your_secret_password_here' with your actual vault password
|
||
echo "your_secret_password_here" > .vault_pass
|
||
```
|
||
|
||
2. **Secure the File:**
|
||
It's good practice to restrict permissions on this file so only you can read it.
|
||
|
||
```bash
|
||
chmod 600 .vault_pass
|
||
```
|
||
|
||
The `ansible.cfg` file is configured to automatically look for this `.vault_pass` file in the project root.
|
||

||
## 2. Common Operations
|
||
|
||
### Running Ansible Commands
|
||
|
||
**IMPORTANT:** All `ansible-playbook` commands should be run from within the `ansible/` directory. This allows Ansible to automatically find the `ansible.cfg` and `inventory.ini` files.
|
||
|
||
```bash
|
||
cd ansible
|
||
ansible-playbook <playbook_name>.yml
|
||
```
|
||
|
||
If you run the command from the project root, you will see warnings about the inventory not being parsed, because Ansible does not automatically find `ansible/ansible.cfg`.
|
||
|
||
The `ansible.cfg` file has been configured to look for the `.vault_pass` file in the project root directory (one level above `ansible/`). Ensure your `.vault_pass` file is located there.
