/var/lib/buttervolume/config/config.ini is not read

[bananer]

In the readme it says, I can put configuration settings into

/etc/buttervolume/config.ini file inside the container or /var/lib/buttervolume/config/config.ini on the host

However, I tried changing my snapshots and volumes path in /var/lib/buttervolume/config/config.ini but they still end up in the default place.

Quickly searching through the code also shows no references to that file, it might be an error in the readme.

However, configuring through a file on the host would be useful to me. I could not figure out the other option of setting environment variables for configuration.

I think this is the bunch of code you are looking for: https://github.com/anybox/buttervolume/blob/master/buttervolume/plugin.py#L14-L37

As you can reand the getconfig doctstring you can also set environment variable to your plugin container.

This should looks likes:

config file	environment	default	description
VOLUMES_PATH	BUTTERVOLUME_VOLUMES_PATH	/var/lib/buttervolume/volumes/
SNAPSHOTS_PATH	BUTTERVOLUME_SNAPSHOTS_PATH	/var/lib/buttervolume/snapshots/
TEST_REMOTE_PATH	BUTTERVOLUME_TEST_REMOTE_PATH	/var/lib/buttervolume/received/	this is used for testing purpose as in production snapshots are send to the remote SNAPSHOTS_PATH
SCHEDULE	BUTTERVOLUME_SCHEDULE	/etc/buttervolume/schedule.csv'
DRIVERNAME	BUTTERVOLUME_DRIVERNAME	anybox/buttervolume:latest
RUNPATH	BUTTERVOLUME_RUNPATH	/run/docker
SOCKET	BUTTERVOLUME_SOCKET	os.path.join(RUNPATH, 'plugins', 'btrfs.sock')

hop it helps

@petrus-v thanks for looking into this!

It seems like the code you pointed to only reads /etc/buttervolume/config.ini inside the container.

The readme file however claims I can also put configuration in /var/lib/buttervolume/config/config.ini on the host, but that is not working for me.

Maybe the readme is incorrect?

Hi @bananer,
maybe it depends whether you build as a docker plugin or not. There is a configuration file here, which is documented here that shows that /etc/buttervolume in the plugin is bind-mounted to /var/lib/buttervolume/config on the host.
