Domains

Claim a DNS zone once and every cluster gets its names under it — certificates and records included.

Claim a domain

  1. 1

    Give Rockslab a DNS key

    Credentials › + Credential, pick your DNS provider. Cloudflare wants an API token that may edit DNS in the zone; a zone on Hetzner DNS uses the account's own token.

  2. 2

    Domains › pick a zone

    The list shows the zones that key can see. Pick one — you cannot type a zone the key cannot see.

  3. 3

    Wait for the check

    Rockslab writes a test TXT record and deletes it right away. Once that works, the domain is ready and can name clusters.

Names on a cluster

A cluster's own names live under its id — pub. and int. levels belong to the platform. Your workloads ask for their own hostnames through their Ingresses and routes, and the cluster's external-dns writes them in its domain and in every domain you attach to it.

Attaching a second domain needs it to be working and written by the same DNS key as the cluster's main one.

Removing one

Domains › the domain › Remove. Do not remove a domain a live cluster is named under — the cluster would lose its names and certificates.
