TODO list (not in order of priority):

• Autogenerate CRD deepcopy.go files and YAML manifests, as one would do with kubebuilder (example of makefile). As of now, CRD YAML manifest and deepcopy functions are manually written.
• Access to image registry is set insecure to make it work with local image registry. Find proper fix.
• Image link must use the local image registry's internal port (i.e. 5000) rather than externally exposed port (e.g. 57321). Possible solution: on-the-fly automatic rewrites?
• Implement undeploy/cancellation use-case. Orchestrator gRPC server needs to implement an undeploy method.
• Set ownership-ref for K8s objects created by Orchestrator.
• Properties in Revision.Status? User might want to know the deployment ID to refer to it later
• Set events on Revision object
• Add code comments
• User documentation
• Automate IAM Service Account creation for Orchestrator (follow these instructions)
