Changelog

1.0 (2015-10-13)

Scheduler

Swarm is now pulling Images in parallel after the scheduling decision has been made, which mitigates the error happening occasionally with Docker pulls blocking the entire scheduler.

General stability

The Node refresh loop process has been improved and does not yield to a panic when removing an Engine and trying to refresh the state at the same time.
The refresh loop has been randomized to better handle huge scale scenarios (> 1000 nodes) where a refresh burst could occur and make the Manager unstable/fail.
General improvements and fixes for the Mesos experimental backend for swarm.

Integration with libnetwork / Support for overlay networking

It is now possible to use the new networking features with Swarm through the network sub-system. Commands like docker network create, docker network attach and docker network ls are now available through swarm.

Integration with Docker Volume Plugins

You can now use the docker volume plugin subsystem available with docker volume.

Leader Election

You can now specify the --replication-ttl flag to control how long it takes for Replicas to be notified of the Primary failure and take over the lead.

TLS

This is now possible to use TLS with discovery for consul and etcd using the new --discovery-opt flag.
