Docker All Predefined address Pools have been fully subnetted

After fixing Docker Network Conflict Fix I found this new error

docker

 failed to create network pvo-kypn-network: Error response from daemon: all predefined address pools have been fully subnetted

There are 8 networks active, which is well under a normal limit. For some reason Docker's default pool is surprisingly small. We can expand it.

sudo nano /etc/docker/daemon.json

add in the default-address-pools line.

❯ sudo cat /etc/docker/daemon.json
