WIP: Terraform module registry
What does this MR do?
Adds api methods that make gitlab acts as a terraform module registry.
Currently implemented only endpoints for version listing and module download
Suddenly it's just only proof of concept. And many thing still should be reworked.
Current problems:
- Terraform module registry service discovery is based on
/.well-known/terraform.jsoncall. So it would require gitlab-omnibus nginx config changes to make it proxy this request to ruby backend - Authorization wasn't implemented yet
- Currently downloading is based on endpoint that download archive for specified sha. If i right understand it's not good because it would require archiving on each download. So for my opinion it would be better to make it based on artifacts.
- Terraform module registry has special endpoint (with auth support)
<base_url>/:namespace/:name/:provider/downloadthat returns URL where module archive could be downloaded. But suddenly terraform doesn't provide auth credentials for file download request itself, so the only way to make secure downloading is providing one-time(short-lived) download URIs or URIs with one-time(short-lived) tokens as a GET parameter. - Only repositories with
terraform-<provider>-<name>name format currently supported. It's made to simplify repository finding (for API handlers). - One repository could contain only one terraform module
