In Kubernetes there is nothing like supported. Instead of it they use validated - it means that all features were tested and validated with some Docker version.

And validated Docker versions are still the same from Kubernetes version 1.8 until 1.11: Docker 1.11.2 to 1.13.1 and 17.03.x. See here: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.8.md#external-dependencies and here https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.11.md#external-dependencies

Starting from Kubernetes version 1.12 Docker 17.06, 17.09 and 18.06 started to be also validated. See here: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.12.md#external-dependencies

As I know final version of Docker 18.09 was released 4 days ago so here we cannot expect this version to be validated in Kubernetes now.

Update (9.4.2019): Docker 18.09 is validated against newly released Kubernetes 1.14: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.14.md#external-dependencies

You can specify exact Docker version for the get.docker.com script by VERSION variable:

export VERSION=18.03 && curl -sSL get.docker.com | sh
