How can I make projects in Running Node-red under Docker

I aleady make projects Running Node-red on locally computer

I'm sorry my Englilsh.

https://nodered.org/docs/getting-started/docker

I don't know even if I read it.

I just save flows.JSON now.

You are going to need to supply a LOT more information about what you've tried and how it didn't work.

The link clearly explains how to run Node-RED in Docker, if you have an existing flow you have a couple of options

  1. Export the flow to the clipboard and then import it into a Node-RED instance running in Docker.
  2. Take the flows.json file and add it to a volume mounted on /data in the container

But without knowing what you've tried and what you already know about running Docker containers, it's really hard to know how to guide you
