I've been able to start my Docker application without a problem but suddenly I get this error:
failed to parse pool request for address space "LocalDefault" pool "" subpool "": could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network
I'm running Docker 1.12.6.
How do I fix this?
I experienced this issue while running an OpenVPN client which was also my default route. Stopping the OpenVPN client worked around the issue.
Turns out there's a limit to the number of simultaneously active Docker networks and I hit that limit.
I got around the issue by removing all my networks:
docker network ls -q | xargs docker network rm
docker-compose down
docker network prune
