Docker Image for MC27
HaWi:
Hi Max,
Is there a way to find out what version the image is (like MC27.0.12 or MC27.0.15 etc)?
many thanks,
Hans

You can look here https://hub.docker.com/r/shiomax/jrivermc27/tags
So currently 27.0.12 seems to be it. I don't think there is 27.0.15 yet for Linux. At least the forum only lists 27.0.12.

Thanks Max, got it.

Thanks for all of your replies to my query about updating of mediacenter in the container. The reason I asked about the updating issue was because jatzoo's image does automatically update on restart (it runs apt-get and updates mediacenter and all of the other dependencies).
I have confirmed that docker compose is available on the QNAP by ssh so I can update that way if I need to, and I've now bind mounted /config so everything is not lost when I update. This is a great idea as I have occasionally had containers become corrupted (by QNAP firmware updates or updates to QNAP container station app).
I have also been playing with 'portainer' as well and I think I should be able to get that to work to do the update in a couple of clicks if I can write a 'custom app template' (it doesn't support compose file version 3 unfortunately). I realise I am just scratching the surface on docker at the moment and there's a lot of functionality to get my head around.
Max - on the 'display' environment variable I ran your image with the default settings on QNAP container station and it reported there was already an xserver running on display=:0 (or something similar) and went into a boot loop. It works fine with display=:1 (both from vnc and via the web ui). That might help someone else who tries to do this on a QNAP NAS, but I can't otherwise explain why it was doing that.
I'd be interested to know what everyone thinks of the performance of the types of docker images. The JRMark benchmark numbers are almost the same for jatzoo vs shiomax. I think the network performance seems to be a bit faster on shiomax?
Thanks again for all of your assistance.

That, you can test images before publishing them and you wont get into situations where you have to pull months worth of updates. Its not really my idea its actually more uncommon to find docker images that update at runtime.

You dont need to use compose its just a suggestion because I like it. Its not magic it just runs docker commands too. If you like something else better use something else.

It should ideally be about the same. After all most of the work in this regard is done by the Linux Kernel People, Debian, JRiver, etc.
I think you should be able to achieve almost equivalent performance to running it on that box without docker. Except when you need GPU performance. Its possible to map dedicated GPU devices to be available in the container as well. But I never really did try that and it may need some additional setup in the image like mapping the alsa sound device did.
