Default project on start

Hi everyone,

I'm looking for creating a new docker of nodered with the project feature.
In my dockerfile i clone my existing nodered project (flow, package.json ...) into the directory projects. /projects/myproject/

But now i did'nt find a way to set the default project (with the value myproject) when i start the docker.
Is it possible to do that ?

Thx for your helping.

I finally found a solution by editing the .config.json file and copy it into my docker.

Hi can you detail your solution? Thanks
