Terminology

Monorepo

In GitOPS a Monorepo is a single Git repository that contains all the declarative configurations (manifests) for an entire operational environment, including applications, services, and infrastructure.

In this document we will use the term Monorepo to refer to such an ArgoCD configurations where there are there two or more Applications tracking different directories in the same branch of the same Git repository, or even an ArgoCD Application that shares same branch in Git Repository with unrelated files that may be changed.

Change Revision

Change Revision is a Git commit that caused a change in the manifests generated by an ArgoCD application.

Git Revision

Git Revision is the current commit in the branch that an ArgoCD Application is tracking. This commit may or may not cause changes in the manifests generated by that ArgoCD application.

ArgoCD Multisource Applications

Argo CD multisource applications allow to specify multiple sources for a single application. Argo CD compiles all the sources and reconciles the combined resources. Those sources may refer to different Git repositories, therefore each source may have its own separate Change Revision and Git Revision.
