# Traefik
#
# Traefik is a reverse proxy, used by Kamal for zero-downtime deployments.
#
# We start an instance on the hosts in it's own container.
#
# During a deployment:
# 1. We start a new container which Traefik automatically detects due to the labels we have applied
# 2. Traefik starts routing traffic to the new container
# 3. We force the old container to fail it's healthcheck, causing Traefik to stop routing traffic to it
# 4. We stop the old container
# Traefik settings
#
# Traekik is configured in the root configuration under `traefik`.
