Trying to transition to running UrBackup in Docker and am hitting some issues I hope someone can help with.
Running on Odroid HC2 with OpenMediaVault 4.1.22-1 and BTRFS file system. I can install UrBackup as a plug-in from the OMV Plug-ins and UrBackup works.
I have tried the uroni/urbackup-server image but it is not multi-platform.
I have also tried whatang/docker_urbackup:armhf-latest. That one gets a bit further but once the container starts I get the following errors in the logs:
2019-06-23 13:59:05: Starting HTTP-Server on port 55414
2019-06-23 13:59:05: HTTP: Server started up successfully!

terminate called after throwing an instance of 'CryptoPP::FileSink::OpenErr'
what(): FileSink: error opening file for writing: urbackup/server_ident_ecdsa409k1.priv
It does not seems like Docker can’t write to the configured directories.
I created a new image that combines the uroni/urbackup-server and whatang/docker_urbackup images.

chown urbackup:urbackup /backups

exec urbackupsrv "$@"This builds and runs. I can open a web browser and navigate to http:[server_ip]:55414 and get:
Sorry. File not found.And the log fills with the following:

I am not clear on what user it is expecting and where to set the user.
Thanks.
