closes #256
This PR add a basic docker discovery system to autorestic. Autorestic can now connect to a docker daemon, check for volumes with a
autorestic.enable
set to1
ortrue
and backup to the backend configured inautorestic.to
label. You can also specify a cron inautorestic.cron
label.This service discovery is only enabled when the
--docker-discovery
flag is set.Since I am used to work with podman and autorestic use the docker command, I needed to add a
--docker-host
flag used to change the host used in the docker command if specified (unix:///var/run/user/1000/podman/podman.sock
for me when working with the podman user socket)The app still need a static configuration file to configure backends and global options. You can also use location both in the static configuration file and docker labels. The new behavior just append the dynamic configuration to the config variable after parsing the config file.
This PR is in draft mode because I would like your suggestions about this feature.
