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

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

Known Issues

When upgrading from 18.09.0 to 18.09.1, containerd is not upgraded to the correct version on Ubuntu. Learn more.
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.


Docker 是一个开源的应用容器引擎,让开发者可以打包他们的应用以及依赖包到一个可移植的镜像中,然后发布到任何流行的 Linux或Windows 机器上,也可以实现虚拟化。容器是完全使用沙箱机制,相互之间不会有任何接口。 [1]
