Add support for incremental stamping #175

Closed randrei-adobe closed 3 months ago

randrei-adobe commented 6 months ago

Description

Modify the create_gitops_pr utility to optionally implement the following algorithm:

Assume the service.yaml file is an output of the service.gitops target
Run service.gitops > service.yaml
Calculate service.yaml digest > service.yaml.digest
Check if the contents of the service.yaml.digest are the same as those committed into git
- Stop if there are no changes to the service.yaml.digest file
Stamp (replace placeholders) service.yaml
Commit and push the changes to service.yaml.digest and service.yaml

Motivation and Context

The existing GitOps PR process creates a new GitOps PR when a ConfigMap object that exposes a volatile file changes even if the deployment artifact doesn't change.
