Thanks @gilbn. If there is no LSIO image for serving files, then this is a container request.
I could follow the instructions from the first link I find on Goolge, but we could all do that for installing all of the other services we are running with LSIO images. But we don’t, because running a docker image that is well supported by an active community is what we all prefer.
There are also several rpi-friendly Samba images on the internet which hasn’t been updated for 3 years.
If others are installing Samba directly on the host OS, is there a reason for that? Docker disk io performance? I used to get 85 MB/s over gigabit ethernet on the old PC I used to use, so I’d be surprised if that is an issue for people.
