Hatch Learning Center has several domains; Tabitha couldn't decide which
she liked best :) At present, they all resolve to the same website, with
_hatchlearningcenter.org_ as the canonical name.
If I remember to add the _acme-challenge CNAME record *before* applying
the Certificate resource, it takes a little under 5 minutes to issue a
new certificate.
The `cert-exporter` tool fetches certificates from Kubernetes Secret
resources and commits them to a Git repository. This allows
certificates managed by *cert-manager* to be used outside the Kubernetes
cluster, e.g. for services running on other virtual machines.
