This project defines a Bindman DNS Manager responsible for receiving DNS updates from clients and updating Azure DNS Zone

Bindman Azure DNS Manager

This repository defines the component that manages Azure DNS Zone.

Azure DNS Zone commands get dispatched from REST API calls defined in the Bindman webhook project Bindman DNS Webhook.

Configuration

The Bindman is setup with the help of environment variables and volume mapping in the following way:

Volume Mapping

A store of records being managed is needed. Hence, a /data volume must be mapped to the host.

Environment variables

1. mandatory BINDMAN_AZURE_RESOURCE_GROUP: specifies the app Resource Group to use.

2. mandatory BINDMAN_AZURE_SUBSCRIPTION_ID: specifies the subscription to use.

3. mandatory BINDMAN_AZURE_CLIENT_ID: specifies the app client ID to use.

4. mandatory BINDMAN_AZURE_CLIENT_SECRET: specifies the app secret to use.

5. mandatory BINDMAN_AZURE_TENANT_ID: specifies the Tenant to which to authenticate.

6. mandatory BINDMAN_ZONE: the zone that the bindman instance is responsible for managing.

7. optional BINDMAN_DNS_TTL: the dns recording rule expiration time (or time-to-live). By default, the TTL is 3600 seconds.

8. optional BINDMAN_DNS_REMOVAL_DELAY: the delay in minutes to be applied to the removal of an DNS entry. The default is 10 minutes. This is to guarantee that in fact the removal should be processed.

9. optional BINDMAN_MODE: let the runtime know if the DEBUG mode is activated; useful for debugging the intermediary files created for sending nsupdate commands. Possible values: DEBUG|PROD. Empty defaults to PROD.
