Warning when starting on Raspberry Pi 4 about docker-plex HOT 7 CLOSED

Yes, it indeed sounds like it's a docker bug. I'm hoping that the workaround I learned will be helpful to someone else.

BTW, I sent you some funds that may help towards a RPI4...or lots of coffee! :)

Cheers!

I have worked around this by doing:

docker pull --platform=linux/arm/v7
docker run -d --restart=always --name plex -v /srv/media:/media -v /srv/media:/root/Library --net=host --platform=linux/arm/v7 jaymoulin/plex

This has silenced the warning. I wonder if I've been running a 64 bit version when it should really be 32 bit though I can't understand how it would even work at all.

Perhaps this will help my stability issues as Plex has stopped responding and I've needed to reboot the server about once a week.

Jay, do you still not have a RPI4 to test with? If not, I'll buy you one - how much are they over there?

from docker-plex.

Rpi4 should be an arm64 architecture. It looks like you installed a special revision on your RPI. armhf should be used for RPI3. Maybe you can try installing Raspberry PI OS which should be more adapted (https://www.raspberrypi.org/software/operating-systems/).

The result of this command : uname -m should give you something like aarch64. This article may help you achive this : https://medium.com/for-linux-users/how-to-make-your-raspberry-pi-4-faster-with-a-64-bit-kernel-77028c47d653

Maintaining an application (answering questions, fixing bugs, adding new features...) is a hard and time consuming process. If you find this product useful and all the effort I put crafting this, I strongly encourage you to donation to help me being able to continue maintaining this and creating other great things on those platforms .

No, I installed the recommended Raspberry Pi OS which is 32bit so uname -m yields armv7l. The 64bit version is still in beta and not yet recommended.

Are you using the beta OS? I was reluctant to use an unrecommended OS with an app as complex as Plex.

from docker-plex.

As you already know, I do not possess RPI4 so i'm not using the arm64 version on my own. Nevertheless, I was able to test RPI4 when crafting the Dockerfiles. Nothing should have changed since then but the different plex upgrades.

Your issue here relies on the fact docker does not identify the correct image for your architecture, therefore, using an incompatible docker image. Had a similiar issue for RPI zero on jaymoulin/docker-jdownloader#22.

You already fixed it by specificly declare use of armhf instead of arm64. You can check that there is nothing for me to fix with this very file: https://github.com/jaymoulin/docker-plex/blob/master/manifest.yml

Thank you very very much for your support <3 This really helps me working on stuff
