Setup

Clone the project and create a K3D cluster with

k3d cluster create --config ./k3d/k3d-cluster-config.yaml

Create a dockerconfig secret with

kubectl create secret docker-registry regcred --docker-server=https://index.docker.io/v1/ --docker-username=<docker-username> --docker-password=<docker-pw> --docker-email=<docker-email>

Create certificate with

kubeseal --fetch-cert > public.pem

And use it to create a SealedSecret

kubeseal --format=yaml --cert=public.pem < regcred.yaml > regcred-sealed.yaml

The SealedSecret is safe to push instead of the Secret itself.
