Sorry if this is more like a docker question than node-red.
I'm porting my node-red flows from pi4 to pi5 where I'm now using docker. It runs fine, except when trying to execute daily backup zip, It looks like zip is not available inside the docker container. Even if I'm getting into the container in console and type zip, I just get command not found. However, exiting the container the same command works fine.
I'm just starting to learn docker but am a long time user of node-red and I understand that the container is kind of isolated from the main os (debian in this case). But I guess there is a solution available.
Yes, flows but also some data etc to Dropbox. I thought there could be such a node available, thanks for the suggestion. But trying to understand the docker concept, I wonder how you would be able to utilize external tools outside the container.
