# authentik-gate-sync: the authentik-gate ingress class. Turns each Ingress of
# that class into an Authentik proxy gate plus the Traefik Ingress, ExternalName
# Service and network policies in front of it. Standard library only, so the
# image is the interpreter plus one file; runs unprivileged as its own user.

# The unit tests gate the image: the final stage copies the controller out of
# this stage, so a failing test fails the build.
