QNAP ContainerStation

[bcjenkins]

Has anyone set up a Docker image in the QNAP NAS? I tried loading sagetv-server-java8 and it seems like there are issues with accessing /dev/urandom or /dev/random.

I am seeing this error in the console:

Fatal Python error: getrandom() failed

Unfortunately, I am not too familiar with Docker.

Do you have options on how you run the container? Can you set "volumes", etc... if so, you might be able to map /dev/random to /dev/random (and likewise for urandom)

Also the unRAID docker container is set to run privileged by default which causes a lot of things under /dev to pass through by default, so I would also make sure it's running in that mode.

I got the same error when I tried to installed the sagetv docker image on my Qnap NAS. Never could figure out a solution...went ahead and installed Linux + Docker on my old WHS mediasmart PC and the sagetv install went smoothly.

FWIW - coppit/sagetv-server:latest runs just fine and
stuckless/sagetv-server-java8:latest gets hung up.

Key difference is coppit starts with a shell script and stuckless starts with Python.

I'd prefer to run Stuckless but have no idea how to troubleshoot Docker, yet.

They SageTV docker that I built is using the phusion base image. That image base is used because it has a formal startup process, supports runing multiple daemons, etc. It uses python to manage that (sagetv itself doesn't require it, but its the startup processing that uses it).

The best way I found to use Docker in QNAP Container Station was to first pull the included Ubuntu 16.04 docker into Container Station and then install the SageTV V9 .deb on top of that, along with the necessary Linux libraries that the SageTV install requires. In Container Station, I also set the network to HOST so my SageTV clients can see the server, and then set a mount point in the container (e.g., /var/media/tv) that points to a NAS shared file directory where I want my SageTV media files to reside. I only have a HD-Homerun that captures OTA channels, so that was easy to configure in SageTV. If you miss configuring something in Container Station for the docker and find out after you have the docker running, just export the existing docker out of Container Station and then change any configuration you want when you import the docker back into Container Station.
