| # Azure | ||
|
|
||
| ## Configuration | ||
|
|
||
| ### Example | ||
|
|
||
| ```json | ||
| { | ||
| "settings": [ | ||
| { | ||
| "provider": "azure", | ||
| "domain": "domain.com", | ||
| "host": "@", | ||
| "tenant_id": "", | ||
| "client_id": "", | ||
| "client_secret": "", | ||
| "subscription_id": "", | ||
| "resource_group_name": "" | ||
| } | ||
| ] | ||
| } | ||
| ``` | ||
|
|
||
| ### Compulsory parameters | ||
|
|
||
| - `"domain"` | ||
| - `"host"` | ||
| - `"tenant_id"` | ||
| - `"client_id"` | ||
| - `"client_secret"` | ||
| - `"subscription_id"` found in the properties section of Azure DNS | ||
| - `"resource_group_name"` found in the properties section of Azure DNS | ||
|
|
||
| ### Optional parameters | ||
|
|
||
| - `"ip_version"` can be `ipv4` (A records) or `ipv6` (AAAA records), defaults to `ipv4 or ipv6` | ||
|
|
||
| ## Domain setup | ||
|
|
||
| Thanks to @danimart1991 for describing the following steps! | ||
|
|
||
| 1. Create Domain | ||
| 1. Activate Azure DNS Zone for that domain | ||
| 1. Find the following parameters in the Properties section of Azure DNS: | ||
| - The name or URL `AnyNameOrUrl` for the query below **TODO** | ||
| - `subscription_id` | ||
| - `resource_group_name` | ||
| 1. In the Azure Console (inside the portal), run: | ||
|
|
||
| ```sh | ||
| az ad sp create-for-rbac -n "$AnyNameOrUrl" --scopes "/subscriptions/$subscription_id/resourceGroups/$resource_group_name/providers/Microsoft.Network/dnszones/$zone_name" | ||
| ``` | ||
|
|
||
| This gives you the rest of the parameters: | ||
|
|
||
| ```json | ||
| { | ||
| "appId": "{app_id/client_id}", | ||
| "displayName": "not important", | ||
| "name": "not important", | ||
| "password": "{app_password}", | ||
| "tenant": "not important" | ||
| } | ||
| ``` |
