nodeup: Did not find docker package for xenial amd64 18.06.3

[ChristopherHanson]

1. What kops version are you running? The command kops version, will display
this information.

1.11.1

3. What cloud provider are you using?

AWS

4. What is the simplest way to reproduce this issue?

Create a cluster on AWS on ubuntu 16.04 (ami-0ad16744583f21877 in us-west-1) without specifying the Docker version in the cluster config.

5. What happened after the commands executed?

Docker is not installed on cluster ubuntu 16.04 cluster nodes and the cluster fails to start; journalctl on the nodes reports:

Mar 05 23:16:21 ip-10-0-16-11 nodeup[1819]: W0305 23:16:21.306809    1819 docker.go:860] Did not find docker package for xenial amd64 18.06.3

6. What did you expect to happen?

kops should install Docker 18.06.3 by default on all cluster nodes

9. Anything else do we need to know?

Setting a docker version to the previous release in the cluster config build the cluster successfully:

spec:
  docker:
    version: 18.06.2

Was it fixed? We are still getting this issue on kops Version 1.12.0-beta.1.

[apjneeraj]

we have the same issue while upgrading cluster from 1.11.x to 1.12.x with kops 1.12.0-beta.2.

Does the workaround of setting the docker and version keys in the cluster config work for either of you? That is essentially how we "solved" the issue, e.g.:

apiVersion: kops/v1alpha2
kind: Cluster
metadata:
  name: example-cluster
spec:
  docker:
    version: 18.06.2

Not sure we've tried anything beyond 18.06.2 at this point though.

18.06.3 seems only to be defined for Ubuntu Bionic (18.04), not Ubuntu Xenial (16.04), even though there are packages for it on the Docker download site.
