Support for adding docker image tag

[mystelynx]

I added 2 options(repository, tag) to itamae docker command.

itamae docker --image=alpine --repository=foo:5000/bar --tag=v1 recipe.rb
# -> created image: repository=foo:5000/bar tag=v1

itamae docker --image=alpine --repository=foo --tag=v2 recipe.rb
# -> created image: repository=foo tag=v2

itamae docker --image=alpine --repository=foo recipe.rb
# -> created image: repository=foo tag=latest

itamae docker --image=alpine --tag=repo:v2 recipe.rb

How about tag option including both repo and tag?

I tried (92db97b)...but it is difficult to support private docker registry.
https://docs.docker.com/engine/reference/commandline/tag/

itamae docker --image=alpine --tag=your-private-repo:5000/foo:v1 recipe.rb

I think this implementation is the simplest, but it is too bother for users. I'll try to fix. thank you!

[mystelynx]

it's a bit difficult to understand. any ideas?

You can use regexp.

[12] pry(main)> /\A(.+?)(|:([^:]+))\z/.match('a')
=> #<MatchData "a" 1:"a" 2:"" 3:nil>
[13] pry(main)> /\A(.+?)(|:([^:]+))\z/.match('a:b')
=> #<MatchData "a:b" 1:"a" 2:":b" 3:"b">
[14] pry(main)> /\A(.+?)(|:([^:]+))\z/.match('a:b:c')
=> #<MatchData "a:b:c" 1:"a:b" 2:":c" 3:"c">
