Install Puppet Content Template from git repository

[sanfrancrisko]

This ticket implements a method to download a PCT from the Github repo it is stored at and install it to the template cache path.

• Requires git to be available on PATH
• Assumes cloning from HEAD
• Ensure any required directory structure in place before cloning to disk
• Ensure that git clones in "clean mode" - i.e. no hidden .git files or metadata
• Use baker-round for testing

User Experience

• pct install --git-uri https://github.com/someone/some-template.git
  • Installs the template from the repository to the default template directory
• pct install --git-uri https://github.com/someone/some-template.git --templatepath ./foo
  • Installs the template from the repository to the foo folder
• Has to work in CI and interactive

Out of Scope

These features are out of scope for this ticket:

• Install from private repository / repository requiring authentication
• Validation of whether the downloaded thing is a fully functional/valid PCT
• Support for anything but default branches
• Support for only installing a subset of templates in a repo

Hello,

Maybe consider https://github.com/hashicorp/go-getter ?

And use as

pct new --template-url git::ssh://git@github.com/puppetlabs/baker-round.git -l

from code is simple as

err := getter.Get(dest, templateUrl)

go getter manage probably all kind of source

(or this is not what the issue desribe ^^)

Thanks for the points @ahmet2mir ! That is good to know. Yes, this is the kind of workflow we're aiming for with that, but have not gotten to how the commandline will be implemented yet.
