Hello! I have a couple of questions, as I also build FIO in an Alpine container, but there I build it from source so that I have all required libraries. The source for the container is here [1] and it is part of the OPNFV StorPerf project, which is for wrapping FIO in a web front end and making it easier to test against various distributions or VMs [2]. My questions are: 1) How are you installing FIO – from the apt repos, or building from source? 2) What storage are you using in the container – a mounted volume or are you trying to use the host OS/raw device? 3) Is the container running as privileged if you are trying to access the host?
