Nodered Projects Feature + flow_refresh sidecar about node-red-chart HOT 3 OPEN

I like this very much @beasteers!

I think combining UI (1) and flow_refresh.py (2) would not work together. I use an UI/Dev Instance with a PVC to develop the flows and settings etc. Like an native instance on a single server. Your option 1.

Later I use the settings, flows etc. and pass them to the helm values together with the side car to install additional node modules from scratch. No matter on which node the pod is starting and with out any PVC. Or on an different cluster. Changes are only deployed with helm upgrade. The node-red interface should not be used (RO, Adminonly) otherwise the newly deployed settings from UI will be lost if the pod is starting on a different node. This approach should cover the kubernetes micro service architecture, with may node-red pods all deployed from main code basis.

Of course, the flow_refresh.py is no perfect at all. External npm packages, themes etc. can not installed this way, as the node-red api do not have this option.
As you mentioned bevor an initContainer could be install npm packages like themes etc. before the container is starting. Actually I have not installed any npm packages via an initContainer.

U should not import flows from an config file with the sidecar when you have enabled the projects mode in node red. You will have two diffrent sources of truth.

If you clone or push from a remote, node red will not auto install node modules from the package.json aka Dependencies Tab but will alert the user. The user can install the node-modules from the dependencies tab by klick on install button.

The project mode needs an seperate sidecar, which is watching the packages.json an runs the flow-refresh.py on any changes. It should than parse the node modules from the package,json directly instead of the env extranodemodules. May be this could work.
Or a node-red feature itself to autoinstall debendencies when pulling or cloning in projects mode.
