Find my Node Red Docker Container?

General
1

Hi,

I’m running Node Red as a Docker Container, on my QNAP NAS, however i can’t work out exactly where all the configuration files are (and having had multiple attempts there are loads of folders listed on the NAS)

Is there anything I can do within Node Red to see where the install/configuration file are located ?

determine the container name:
docker ps

then:
docker inspect <node-red-container-name>

you will find:

"HostConfig": {
            "Binds": [
                "/path:/path"
            ],}

Thanks @bakman2

I did as you suggested and it returned a lot of information - the host and binds you’d mentioned only shows this, but there was some interesting information above - which I have added below??

Also check Mounts and/or Volumes

Something called "GraphDriver" looks interesting , and has a mounts section..

Here you go..

It looks like you are using the flows.json file inside the docker container, if you restart the container, you still have flows ?

Oh yes, stop/start all the flows are still there..
