The App Platform includes an internal self-hosted Git service powered by Gitea. When creating a Build, the repository type by default is set to internal so you can select one of the internally hosted Git repositories. In this lab we'll use the Build feature to build an image using an external private repository (Github) with basic-auth authentication.
