I have a docker stack with a few services with their data stored on an external volume. The volume driver is the rexray/dobs (for digitalocean block spaces)
The definition for the volume is like so
version: "3"
services:
...
volume_name:
driver: rexray/dobs
driver_opts:
size: 2
The above automatically creates for me a 2GB block storage volume.
I would like to upgrade the size to something higher. Simply changing
size: 2
to
size: 3 #or something higher
and running
docker stack deploy ...
does not work.
Is there a way to increase the size of the already existing volume using instructions from the docker compose file?
