Re-check before stopping

Inspect an instance before stopping it when its session expires, and skip the stop if it is not labelled sablier.enable=true.

# compose.yml
services:
  sablier:
    image: sablierapp/sablier:1.19.0
    command:
      - start
      - --provider.name=docker
      - --provider.verify-enabled-on-expiration=true
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

  unlabeled:
    image: acouvreur/whoami:v1.10.2

When the session for the unlabeled container expires, Sablier inspects it, finds no sablier.enable=true label, and leaves it running.

With --provider.verify-enabled-on-expiration=true, Sablier inspects an instance before stopping it when its session expires, and skips the stop if the instance is not labelled sablier.enable=true. This protects containers that are no longer (or were never) Sablier-managed from being stopped when an old session expires.

When to use it

Use this when a session may outlive a container’s Sablier labels, for example if a container is redeployed without the label, and you want to be sure Sablier never stops something it does not currently manage.

Flags

• --provider.verify-enabled-on-expiration: inspect an instance on session expiration and only stop it if it is still labelled sablier.enable=true.

See the runnable example.
