Paketo Buildpack for Git

The Paketo Buildpack for Git is a Cloud Native Buildpack that retrieves git metadata and performs git operations.

The buildpack is published to DockerHub for consumption at paketobuildpacks/git.

Behavior

This buildpack uses the git dependency off of the stack that it is running on top of. The Git buildpack will only participate if there is a valid .git directory in the application source directory or if there a git-credentials service bindings present.

The buildpack will do the following:

• Sets the REVISION environment variable, which is the commitish of HEAD, to be available for the build processes of other buildpacks and in the final running image.
• Sets the org.opencontainers.image.revision label with the same commitish as the REVISION environment variable.
• Creates custom git credential managers if it is provided with credentials through a binding.

Bindings

The buildpack optionally accepts the following bindings:

Type: git-credentials

Key	Value	Description
credentials	<formated git credentials>	The credentials file should have the following format to conform with the git credential structure.
context (optional)	<url>	The context is an optional pattern as defined by git. If a context is not provided then the credentials given in the binding will be the default credentials that git uses when authenticating. A given context can only be used once for any group of bindings, if a context is given by two separate bindings the build will fail.
