# Vault
|
|
|
|
|
Sensitive data is stored under two files in the `vault` directory:
|
|
|
|
|
- `user_provisioning.yml` contains the vault password
|
|
|
|
|
- `vault.yml` contains the sensitive data
|
|
|
|
|
|
|
|
|
|
## user_provisioning.yml
|
|
|
|
|
Configure users for provisioning and manual maintenance
|
|
|
|
|
```yaml
|
|
|
|
|
vault_atmen_password: <atmen_password>
|
|
|
|
|
vault_maintainer_user: <your_user>
|
|
|
|
|
vault_maintainer_password: <maintainer_password>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## vault.yml
|
|
|
|
|
Configure k3s secrets
|
|
|
|
|
```yaml
|
|
|
|
|
ansible_become_password: <atmen_password>
|
|
|
|
|
token: <k3s_token>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
To avoid pasting your vault password everytime, you can create a `.vault_pass` file in the root directory with the vault password.
