Node red and docker and mount

[pvklink]

I am busy with dockering my domotica environment.

I use the following compose-file and dockerfile to docker nodered and some dependencies
Questions i have:

1. i like to mount a usb drive to node-red to store camera-data on it during a nodered flow
   How can i achive that ?

2. i tried to test these commands within the nodered-container with
   sudo docker exec -i -t nodered /bin/sh
   But when i put commands in this container like: dir i get : command not found!
   How can i make these container a little bit smarter...

From what i understand, NodeRED is running as a service seeing from your docker-compose file. So you want to use a directory inside node-red? Do you mean with node?

The paths as far as the container go are isolated. so you can store to a directory like /usr/data/some_folder as long as you know what the directory is.
The next step would be to mount this directory as a volume to the host system. you would have to write this inside your docker-compose file inside the nodered service.

volumes: 
        - /Drive_location : /usr/data/some_folder 

The right part amounts to the directory inside the container that node will use, and the left part is the drive you want to link.

I like to:

1. store data from a flow to a folder x
2. x is in fact an usb drive (OR a folder on the usb drive)
3. x must be available outside node-red

Solved it, wil publish the solution soon
