# PREREQUISITES:
# 1. Build and push the container image:

# # docker tag contact-mailer:latest gitea.felhom.eu/felhom/contact-mailer:latest
# # docker push gitea.felhom.eu/felhom/contact-mailer:latest
# # Option B: Import directly into k3s (single node):
# # docker save contact-mailer:latest | sudo k3s ctr images import -
#
# 2. Create the Secret with your Resend API key:
# kubectl create secret generic contact-mailer-config \
# --namespace=felhom-system \

#
# 3. Apply this manifest:
# kubectl apply -f contact-mailer.yaml
