How to load a specific flow whenever Node-red server is started through docker?

I am running Node-red server through docker-compose and it creates new flow every time the 'docker-compose up' is executed. How to prevent this from happening? And how to load/import a specific flow instead of the new one as it is hectic to copy the nodes on to the new flow every time? Thank you!

You need to pass in the name of flow to use, how to do this is described in the README for the Node-RED docker image:

$ docker run -it -p 1880:1880 -e FLOWS=my_flows.json nodered/node-red-docker

You will also need to mount your own data directory so the flow is persisted across new instances being created, again this is in the README here

$ docker run -it -p 1880:1880 -v ~/.node-red:/data --name mynodered nodered/node-red-docker

so combining the 2 will get you:

$ docker run -it -p 1880:1880 -e FLOWS=my_flow.json -v ~/.node-red:/data --name mynodered nodered/node-red-docker

You will have to take that command line and map it into the docker-compose file.
