Update action server without redeploying the k8 cluster

[tatianafrank]

We are running Rasa X on a Kubernetes cluster. We know that the external action server can be added via the environment variable ACTION_SERVER_TAG but how do we update Rasa when we make changes to the action server? Do we have to manually go into the kubernetes cluster, change the environment variable and redeploy those changes to the k8 cluster? It doesnt seem manageable at all. We can continually make changes to the core/model using the UI or github and we would like a similar continuous development solution for the action server since we make changes to the action server almost as often as we make changes to the core.

You may find help in the docs and the forum, too 🤗

In principle you're right, you need to change the env variable/the value in values.yml and run helm upgrade.

For your model, how are you updating it when changes are made? Is this step fully automated as part of a CD action?

In a CD github action, you could potentially update the tag and redeploy/run helm upgrade from there, which would automate the updates.
