v1.0.1

1.0.1 (2015-12-09)

Scheduler

• Set labels for pending containers to fix scheduler failure

Discovery

• Increase default TTL and heartbeat values to reduce traffic to discovery

• Fix network connect/disconnect for overlay network
• Fix connection leak on TLS connections
• Fix CLI hang on events command
• Fix newline issue with events
• Improve OPTIONS handler
• Fix image digest
• Fix memoryswappiness default value
• Enable profiling for HTTP in debug mode

Node Update

• Provide options on swarm node update frequency

Mesos integration

• Change offers timeout default to prevent other frameworks starvation
• Improve error output for bad swarm mesos user
• Fix connection failure when using Mesos with ZooKeeper

Misc

• Update to Go 1.5.2
• Documentation update

Downloads:

docker pull swarm:1.0.1

v1.0.0

Noteworthy changes from 0.4.0

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.

docker pull swarm:1.0.0-rc3

v0.4.0

Noteworthy changes from 0.3.0

Scheduler

• If an image cannot be pulled, Swarm will attempt to schedule the container on a node that already has it. This makes scheduling local images (built by docker build but not available on the registry) possible on Swarm.
• Prevent a crash when a freshly created container cannot be retrieved from an Engine

Store

• Migration to libkv for the storage backends
• Include bug fixes on node discovery and Leader Election for Consul, etcd, and zookeeper
• Consul backend fails explicitly when given multiple endpoints instead of discarding

Replication

• Fault tolerant Leader Election process

API

• Fix status code for docker exec and docker pull
• Fix docker push name matching
• Add new endpoints for docker cp
• Improved error messages thrown at pull
• Improved build process: It now accepts resource constraints (-c and -m) to schedule the build on a suitable machine.
• Fix content-type for load

Docker Engine Compatibility

• Improve docker info with docker client 1.7.x
• Add SystemTime, http_proxy, https_proxy and no_proxy to docker info

Mesos integration

• Task creation timeout configurable
• Fix issue with hostname in library image
• Use docker_port attribute if available
• Add support for random ports

Misc

• Add documentation on Leader Election / High Availability of swarm manager
• Lots of typos/improvements to the documentation
• Switch to golang 1.4
