docker-caddy-azuredns

A Caddy Server Docker container with the Azure DNS Provider.

Based heavily on the code at https://github.com/SlothCroissant/caddy-cloudflaredns

Builds are available at the following Docker repositories:

• GitHub Container Registry: https://ghcr.io/best-family/docker-caddy-azuredns

A few things to note:

1. Ensure you're signed into the GitHub container registery.

   docker login ghcr.io -u <YOUR GITHUB USERNAME>

Refer to the GitHub documentation if required.

2. You should add Azure client related values as environment variables to your docker run command. Example:

   docker run -it --name caddy \
       -p 80:80 \
       -p 443:443 \
       -v caddy_data:/data \
       -v caddy_config:/config \
       -v $PWD/Caddyfile:/etc/caddy/Caddyfile \
       -e AZURE_TENANT_ID=00000000-0000-0000-0000-000000000000 \
       -e AZURE_CLIENT_ID=00000000-0000-0000-0000-000000000000 \
       -e AZURE_CLIENT_SECRET= \
       -e AZURE_SUBSCRIPTION_ID=00000000-0000-0000-0000-000000000000 \
       -e AZURE_RESOURCE_GROUP_NAME= \
       -e ACME_AGREE=true \
       best-family/docker-caddy-azuredns:latest

3. You should add the following to your Caddyfile as the tls directive.

    tls {
      dns azure {
        tenant_id {$AZURE_TENANT_ID}
        client_id {$AZURE_CLIENT_ID}
        client_secret {$AZURE_CLIENT_SECRET}
        subscription_id {$AZURE_SUBSCRIPTION_ID}
        resource_group_name {$AZURE_RESOURCE_GROUP_NAME}
      }
    }
