Thanks Juan, Do they work in K8S manifests? how would I use it to replace <project_name-data> in that k8s manifest?

I think it should work with manifests also. I'll try to find a slot tomorrow to write an example that may work for your use case.

Thanks Juan

Hi @hundreds-terabyte-36933. I made a test, and it seems it's just for helm charts. I found this thread on GitHub that recommends converting the deployment to a helm chart. That should not be a very big hassle; I hope it works for you. https://github.com/rancher/fleet/issues/355
