If set, files are downloaded from that URL instead of from the roon servers
FORCE_ARCH
If set, we are using the value instead of uname -m when selecting the binary file to use/download. This can be useful for example with LibreElec or OSMC on the Pi4, which have a 64bit kernel (aarch64) but a 32bit docker version: in this situation, then container starts but then the binary does not work. Setting this variable to armv7l solved the issue for me. Possible values are aarch64, armv7l and x86_64.
Volumes
Volume
Description
/files
If set, we try and see if the volume contains the files that would instead be downloaded. Setting this volume can speed up the startup phase slightly.
Example
You can use the published images or the one you build by yourself. See the repo here.
