Kops: Map Docker 1.12.6

[justinsb]

Let's define the package mappings for docker 1.12.6 - or figure out if we can avoid having to map them.

It looks like 1.12.6 is going to be validated: https://github.com/kubernetes/kubernetes/issues/40061

Any progress on this ? We are currently stuck with docker 1.12.3 which is known for its deadlock issues.

Now that 1.6 is almost released I think it'll be safe to move on 1.12.6

This PR has been merged: https://github.com/kubernetes/kops/pull/2283
So I guess this issue can be closed?

[robinmonjo]

Yes probably. Will we be able to install docker 1.12.6 on a kubernetes 1.5.6 cluster ?

[stijndehaes]

If you upgrade to the latest kops version when it gets released with this PR. Then I guess you should be able to.

@robinmonjo , we installed Docker 1.12.6 (via kops 1.6.0-alpha.2) on several k8s 1.5.2 clusters last week and have had no issues with it (so far).

Thank you @ebbeelsborg for your feedback, I guess this + https://github.com/kubernetes/kops/issues/2279 should fix docker deadlocks issues for good. Still using docker 1.12.3 but with the "docker nany" script and had no issue. I'll plan to update to docker 1.12.6 when kops 1.6 get released

@justinsb is this work done?

Closing as 1.12.6 is in the docker model
