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.

0.4 (2015-08-04)

Scheduler

  • Reschedule with soft affinity when image cannot be pulled

Store

  • Replace the store pkg by libKV
  • Fixes about consul/etcd and zookeeper

API

  • Fix docker exec status code
  • Fix docker pull status code

Docker Engine Compatibility

Mesos integration

  • Task creation timeout configurable
  • Fix issue with hostname in library image
  • Use 'docker_port' attribute if available

Misc

  • Lots of typos/improvements to the doc
  • Switch to golang 1.4
