Hi @jimma - I had a quick look, and have just a minor comment, since I didn't dive in properly yet for a detailed code review.

In the meanwhile, I am asking whether we can deal with #1311 separately and I'd ask the same for the Fabric8 -> JKube Maven plugin (where maybe I could help, as well).

WDYT?

Thanks again for your work on these changes, @jimma
I've gone through the commits you added, and the incremental changes the introduce.
Regarding the boot2Docker and Docker Machine modules removal, I am fine with the changes and dropped just one question about a commented out block.

Again, regarding Fabric8 Maven plugin -> JKube Maven plugin, I am not sure I get the reasoning for not addressing it in a separate PR, but maybe I am missing something.
Could you please elaborate on this? I know we discussed the replacement in chat, but a dedicated issue/PR would be better IMHO.

Update: now I see that the related issue (#1308) is actually more generic, therefore the Fabric8->Jkube related changes could fit in here.
If that is the case @jimma - would you please change the PR title to either mention both boot2Docker and Fabric8 Maven plugin removal/replacement or none of them?

Thanks @fabiobrz for the review again.

@jimma one minor comment on the latest tag usage in the DockerTemplate, others LGTM :)
