The Argo CD CLI has been a cornerstone for managing GitOps workflows, but until now, it lacked support for extending its capabilities through plugins. This talk introduces plugin support to the ArgoCD CLI, enabling users to create custom plugins and use them as subcommands, extending the ArgoCD CLI functionality like kubectl.

In this talk, we’ll demonstrate the new plugin system’s real-world application by showcasing a plugin we developed: mta (Migrate to Argo CD). This plugin bridges the gap between Flux and Argo CD by exporting Flux components into Argo CD-compatible Custom Resources (CRs), simplifying migrations from Flux to Argo CD.
