Release date: 11/17/2016

New

  • Docker Engine upgraded to Docker 1.13.0-rc1
  • Changes to port 2375 access. For security reasons we locked down access to port 2375 in the following ways.
    • You can’t connect to port 2375 on managers from workers (changed)
    • You can’t connect to port 2375 on workers from other workers (changed)
    • You can’t connect to port 2375 on managers and workers from the public internet (no change)
    • You can connect to port 2375 on workers from managers (no change)
    • You can connect to port 2375 on managers from other managers (no change)
  • Added changes to the way we manage swarm tokens to make it more secure.

Important

  • Due to some changes with the IP ranges in the subnets in Beta10, it will not be possible to upgrade from beta 10 to beta 11. You will need to start from scratch using beta11. We are sorry for any issues this might cause. We needed to make the change, and it was decided it was best to do it now, while still in private beta to limit the impact.

1.12.3-beta10

Release date: 10/27/2016

New

  • Docker Engine upgraded to Docker 1.12.3
  • Fixed the shell container that runs on the managers, to remove a ssh host key that was accidentally added to the image. This could have led to a potential man in the middle (MITM) attack. The ssh host key is now generated on host startup, so that each host has its own key.
  • The SSH ELB for connecting to the managers by SSH has been removed because it is no longer possible to SSH into the managers without getting a security warning
  • You can connect to each manager using SSH by following our deploy guide
  • Added new region us-east-2 (Ohio)
  • Fixed some bugs related to upgrading the swarm
  • SSH keypair is now a required field in CloudFormation
  • Fixed networking dependency issues in CloudFormation template that could result in a stack failure.

1.12.2-beta9

Release date: 10/12/2016

New

  • Docker Engine upgraded to Docker 1.12.2
  • Can better handle scaling swarm nodes down and back up again
  • Container logs are now sent to CloudWatch
  • Added a diagnostic command (docker-diagnose), to more easily send us diagnostic information in case of errors for troubleshooting
  • Added sudo support to the shell container on manager nodes
  • Change SQS default message timeout to 12 hours from 4 days
  • Added support for region ‘ap-south-1’: Asia Pacific (Mumbai)

Deprecated:

  • Port 2375 will be closed in next release. If you relay on this being open, please plan accordingly.

New

Errata

  • Upgrading from previous Docker for AWS versions to 1.12.0-beta4 is not possible because of RC-incompatibilities between Docker 1.12.0 release candidate 5 and previous release candidates.

1.12.0-beta4

Release date: 7/28/2016

New

  • Docker Engine upgraded to 1.12.0

Errata

  • Upgrading from previous Docker for AWS versions to 1.12.0-beta4 is not possible because of RC-incompatibilities between Docker 1.12.0 release candidate 5 and previous release candidates.

1.12.0-rc5-beta3

(internal release)

1.12.0-rc4-beta2

Release date: 7/13/2016

New

  • Docker Engine upgraded to 1.12.0-rc4
  • EC2 instance tags
  • Beta Docker for AWS sends anonymous analytics

Errata

  • When upgrading, old Docker nodes may not be removed from the swarm and show up when running docker node ls. Marooned nodes can be removed with docker node rm

1.12.0-rc3-beta1

New

  • First release of Docker for AWS!
  • CloudFormation based installer
  • ELB integration for running public-facing services
  • Swarm access with SSH
  • Worker scaling using AWS ASG

Errata

  • To assist with debugging, the Docker Engine API is available internally in the AWS VPC on TCP port 2375. These ports cannot be accessed from outside the cluster, but could be used from within the cluster to obtain privileged access on other cluster nodes. In future releases, direct remote access to the Docker API will not be available.
  • Likewise, swarm-mode is configured to auto-accept both manager and worker nodes inside the VPC. This policy will be changed to be more restrictive by default in the future.
