Hallo all,
node-Red runs in a Docker container on the Plc Next F 2152.
I am currently facing the problem that I would like to save CSV files on my PLC via Node-Red. Unfortunately, this controller currently refuses to execute Node-RED mkdir commands. Do you have any idea how I can give permission in Node-Red to create/modify/overwrite/delete files under a certain path at any time?

Instead of giving node red more permissions: it is better to assure that the node red user has the permissions to create directories in that folder.
If the folder is on a mounted volume then you can most likely give it those permissions by logging on to the docker host machine and using the standard unix commands to set permissions.
