# C2C Farm backend image — CI template.
# Builds the full-ComfyUI farm image (renderfarm/docker/Dockerfile + the
# pinned custom_nodes_manifest.txt) and pushes to ACR and/or ECR.
#
# TEMPLATE: wire the secrets below in repo settings before enabling.
#   ACR:  ACR_LOGIN_SERVER, ACR_USERNAME, ACR_PASSWORD
#   ECR:  AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, ECR_REPOSITORY
# Runs on manual dispatch (images are ~20GB — don't build per-push).
