The format for node advertisement in swarm and docker engine (for networking) is the same, and can be shared. Doing so allows us to start toward removing the swarm-join container, and improves our HA situation after engine discovery is run. Resolves #670. Specifically, swarm was previously somewhat HA: if you set up 1 controller, 2 replicas and 1 node, then you could lose the controller and still remain functional unless the swarm node needed to restart. This change improves HA by removing the above failure mode as long as engine discovery has been run and is up to date. See also docker/swarm#1368 which implemented this flag, and lays out the future scenario we hope to achieve, and also #1032 which is our goal of removing swarm join with automatical engine discovery. |
