The beta for Docker Engine 18.09 is out
We have some pretty exciting news coming from the Docker team! The beta for Docker Engine 18.09 is now available! So get yourself a copy of the new beta and start submitting those issues!
A couple of months ago, we discussed some changes that went live in Docker CE 18.06. The 18.06 release was the last one to have a 4-month maintenance lifecycle with the team announcing more extended cycles for Docker Engine – Community.
As part of these changes, the team announced the beta period for the Docker Engine in hopes of delivering higher product quality.
So get ready – The game’s on!
The new features
It wouldn’t be any fun if you didn’t have any new things to try out now, would it?
Here are the new features you can find in the Docker Engine 18.09 beta.
- Built on containerd – Docker Engine’s new architecture is based on containerd 1.2 and fully supported through the Kubernetes containerd integration.
- BuildKit is now generally available – Access improved build performance (see slides 22-26) and scalability with the optional BuildKit integration. BuildKit remains opt-in with an environment variable, e.g.
- Support for SSH connections to the docker host – The client can now connect to a remote docker daemon via SSH, e.g.
Can’t wait to give it a go?
You can install the beta package on a new system without the need to have previous versions of docker-ce installed.
$ curl -fsSL test.docker.com -o test-docker.sh $ sh test-docker.sh # helper script installs the beta package $ docker --version # verify install Docker version 18.09.0-ce-beta1, build 78a6bdb
You can submit issues via GitHub issues.
