18.09.1

2019-01-09

Important notes about this release

In Docker versions prior to 18.09, containerd was managed by the Docker engine daemon. In Docker Engine 18.09, containerd is managed by systemd. Since containerd is managed by systemd, any custom configuration to the docker.service systemd configuration which changes mount settings (for example, MountFlags=slave) breaks interactions between the Docker Engine daemon and containerd, and you will not be able to start containers.

Run the following command to get the current value of the MountFlags property for the docker.service:

sudo systemctl show --property=MountFlags docker.service
MountFlags=

Update your configuration if this command prints a non-empty value for MountFlags, and restart the docker service.

Packaging

Known Issues

  • When upgrading from 18.09.0 to 18.09.1, containerd is not upgraded to the correct version on Ubuntu.
  • There are important changes to the upgrade process that, if not correctly followed, can have impact on the availability of applications running on the Swarm during upgrades. These constraints impact any upgrades coming from any version before 18.09 to version 18.09 or greater.

Known Issues

  • There are important changes to the upgrade process that, if not correctly followed, can have impact on the availability of applications running on the Swarm during upgrades. These constraints impact any upgrades coming from any version before 18.09 to version 18.09 or greater.

  • With https://github.com/boot2docker/boot2docker/releases/download/v18.09.0/boot2docker.iso, connection is being refused from a node on the virtual machine. Any publishing of swarm ports in virtualbox-created docker-machine VM's will not respond. This is occurring on macOS and Windows 10, using docker-machine version 0.15 and 0.16.

    The following docker run command works, allowing access from host browser:

    docker run -d -p 4000:80 nginx

    However, the following docker service command fails, resulting in curl/chrome unable to connect (connection refused):

    docker service create -p 5000:80 nginx

    This issue is not apparent when provisioning 18.09.0 cloud VM's using docker-machine.

    Workarounds:

    This issue is resolved in 18.09.1.

Deprecation Notices

  • Docker has deprecated support for Device Mapper as a storage driver. It will continue to be supported at this time, but support will be removed in a future release.

    The Overlay2 storage driver is now the default for Docker engine implementations.

For more information on the list of deprecated flags and APIs, have a look at the deprecation information where you can find the target removal dates.

End of Life Notification

In this release, Docker has also removed support for TLS < 1.2 moby/moby#37660, Ubuntu 14.04 "Trusty Tahr" docker-ce-packaging#255 / docker-ce-packaging#254, and Debian 8 "Jessie" docker-ce-packaging#255 / docker-ce-packaging#254.
