Docker image fails on Raspberry Pi 4

[vexance]

The following error occurs when attempting to run the docker image on a Raspberry Pi 4 with Alpine 3.14, causing the container to stop:

standard_init_linux.go:228: exec user process caused: exec format error

I believe this is due to the Alpine version in the Dockerfile being specified as 3.13.6, which might not support ARM 64 CPU architecture. Alpine's Official Dockerhub Image specifies the following tags as being supported:

    20210804, edge
    3.15.0-rc.4, 3.15
    3.14.3, 3.14, 3, latest
    3.13.7, 3.13
    3.12.9, 3.12
    3.11.13, 3.11

Updating the Dockerfile from ARG alpine_version=3.13.6 => ARG alpine_version=3.14.3 resolves the issue on my device.

Sorry for the late response. Fixed via #106
