+# Deploys an instance of Nixery into the cluster.
+#
+# The service via which Nixery is exposed has a private DNS entry
+# pointing to it, which makes it possible to resolve `nixery.local`
+# in-cluster without things getting nasty.
+#
+# The 'nixery-keys' secret was configured manually using a created
+# service account key. This does not use metadata-based authentication
+# due to the requirement for having an actual PEM-key to sign with.
