VCS Providers

Suggest Edits

VCS providers enable Scalr to access Terraform configuration files and OPA policies held in a version control system (VCS) such as Github, Gitlab, Bitbucket, and Azure DevOps. VCS providers are required if a GitOps model is desired. There is no extra configuration needed for Scalr to send checks back to VCS providers during the pull request process. VCS providers are created at the account and will be made available to all environments within the account or assigned to specific environments.

To manage VCS providers at the account scope, click on VCS providers:

Currently supported VCS providers:

  • GitHub SaaS
  • GitHub Enterprise
  • GitLab SaaS
  • GitLab CE/EE
  • Azure DevOps Services
  • Bitbucket Cloud
  • Bitbucket Data Center
