Requirements

mhutter.docker-systemd-service must be installed.

Role Variables

The same as mhutter.docker-systemd-service, plus the listed extra ones:

• traefik_router_labels: List of labels being prefixed for traefik with the container_name. E.g. entrypoints=websecure becomes the label traefik.http.routers.myapp.entrypoints=websecure (or during zero-downtime deployment traefik.http.routers.myapp-tmp.entrypoints=websecure)
• same_tag: Boolean, ensures deploying works with the same tag (by deleting the old one)
• rolling_update: Boolean, creates a temporary systemd service for a docker container that takes the traefik while the original one is updated
• service_startup_time: Default 2, time in minutes until rolling update is resumed and previous service is taken down
