Docker 18.09.3 for Centos

[CarpathianUA]

1. What kops version are you running? The command kops version, will display
this information.
1.13.0

2. What Kubernetes version are you running? kubectl version will print the
version if a cluster is running or provide the Kubernetes version specified as
a kops flag.
1.13.9

3. What cloud provider are you using?
AWS

According to that PR (merged) #6347 there is no possibility to use Docker 18.09.3 with RedHat-based distros. Is it true?

Appreciate your help!

As per https://github.com/kubernetes/kops/blob/master/nodeup/pkg/model/docker.go#L664 you have 18.09.3 only for Debian Stretch. I stumbled upon this because I am using Ubuntu and I also need it. 🤕

Let's see if I have time to at least test it for my Xenial needs.

[CarpathianUA]

Yes, exactly @marsavela
I also mentioned that. An it's really confusing me as well :)

@CarpathianUA May I ask why are you looking for 18.09.3 in particular?
You can find higher versions at https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

I just did some testing with 18.09.9 in Xenial and worked as expected. I don't know if I should send a PR though. 😕

Hi @marsavela ,
I'm looking especially for RedHat-based distros support (Centos/RHEL) for version >= 18.09.3.
Actually, according to https://github.com/kubernetes/kops/blob/master/nodeup/pkg/model/docker.go there is no support for such versions. Maybe I'll create a PR soon.

@CarpathianUA would be great if you can compile it and test it as well. Maybe we can ping some owners to know if PRs would be a good idea... According to the guidelines the repo owners would need to approve this. 🙄

Pinging @mikesplain since he's the one that merged the previous PR #6347

[marsavela]

Bumping this back up. Maybe we can get an approval. I already have a branch for Ubuntu...
