docker linux/arm64 build

[aniston]

The docker builds in linux/amd64 worked for the Frontend and Recorder and thanks for that.

While testing the ARM ARCH only the owntracks/frontend runs but cannot run the owntracks/recorder container as it does not have a linux/arm64 OS/ARCH with the container log error exec /usr/sbin/entrypoint.sh: exec format error

• any chance of an official linux/arm64 arch for the owntracks/recorder ?

That sounds as though the hash-bang line isn't being recognized. entrypoint.sh contains

#!/bin/sh

in its first line.

Could you please show the output of these two commands?

$ ls -l /bin/sh
$ ls -lL /bin/sh

from inside the container?

[aniston]

@jpmens thanks for looking into the issue.

sadly i cannot run anything inside the container as it is not running or better still constantly restarting.
Error response from daemon: Container 71d430f4aa3adc8145701f760b8089940295f8184b8e642ab64c51b20e1c9976 is restarting, wait until the container is running

I used the following command on the container:
docker exec -it otrecorder "ls -l /bin/sh"

• is there another way to run those commands on a container that is not starting or restating ?

If this helps , here is the only log line before the container restarts in a loop
2023-04-26T16:20:03.525424778Z exec /usr/sbin/entrypoint.sh: exec format error

[jpmens]

Does this work?

docker run -it --entrypoint=/bin/sh otrecorder

Though if it does, then /bin/sh is there and it's executable so that will invalidate my earlier assumption that the shell is broken.

[jpmens]

If you do get a shell, then please show the output of

cat /usr/sbin/entrypoint.sh
env

This smells to me like an architecture mismatch i.e. you are running an Arm image on an amd64 host or vice versa.

[aniston]

you are running an Arm image on an amd64 host or vice versa.

yup exactly, that's the reason for the request for an arm64 build.

[aniston]

docker run -it --entrypoint=/bin/sh otrecorder

this does not work as per the same bild issue , ie: ARCH mismatch from pulled image incompability.
I paste the resulting error message from docker.

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
exec /bin/sh: exec format error

@jpmens I am using a Hetzner VPS with ARCH=ARM64 ARM Ampere CPU and sucessfully built the Docker image on the docker host using the Dockerfile on github with

docker buildx build -t otrecorder:arm64 github.com/owntracks/docker-recorder

this image runs correctly in the container, so if needed I can carry out some test here.

• the host OS is linux aarch64 Debian GNU/Linux 11 (bullseye) with Kernel Version 5.10.0-21-arm64

EDIT: 20230501:
pushed my 'otrecorder' arm64 build to docker hub at cavia/otrecorder:arm64 if anyone wants to try that out under ARM cpu.

the Dockerfile is the same from owntracks/docker-recorder.

Apologies for this taking so long, but if I haven't messed this up, we now have Recorder images for ARM:

We'd appreciate your testing!

[jpmens]

We have reports that these are working. Closing as completed.

@jpmens , seen this message only today and tried out your official docker-recorder build, yes it works fine, I had till today resorted to using my own docker image at cavia/otrecorder for arm64 hence i forget to check this ticket. I confirm that on my ARM VPS at Hetzner it workes correctly, Thanks for the ARM64 image.
