External DNS

This section describes how to use external-dns to maintain your DNS records

You require a DNS record when setting up a custom domain for your cluster. You can either create one manually, or set up the external-dns service to manage your DNS record automatically.

If you choose to use external-dns to maintain your DNS records, the external-dns will take care of pointing the DNS record to the ingress of the cluster automatically.

The following example shows how to configure external-dns to manage DNS records in AWS Route 53 automatically:

  1. Open the kommander.yaml file:

    1. If you do not have a kommander.yaml file, initialize the configuration file, so you can edit it in the following steps. WARNING: Initialize this file only ONCE, otherwise you will overwrite previous customizations.

    2. If you have initialized the configuration file already, open the kommander.yaml with the editor of your choice.

  2. Adjust the app section of your kommander.yaml file to include these values:

        enabled: true
        values: |
              secretKey: <secret-key>
              accessKey: <access-key>
            region: <provider-region>
            preferCNAME: true
          policy: upsert-only
          txtPrefix: local-
            - <>
  3. In the same app section, adjust the traefik section to include the following:

        enabled: true
        values: |

Refer to the external-dns documentation for more information, as well as further instructions on how to configure external-dns to use other DNS providers like Google Cloud DNS, CloudFlare, or on-site providers.
