user:~$ echo 'docker compose --compatibility "$@"' | sudo tee -a /usr/local/bin/docker-compose && sudo chmod +x /usr/local/bin/docker-compose

Configuring default address pool

The Docker daemon pulls a /16 address space for each automatic network setup, starting from 172.17.0.0/12 until it starts eating into the 192.168.0.0/16 address space as well¹⁾. This may conflict with any internal subnets associated with your network²⁾.

To mitigate this problem, use an unused address range and also reduce the number of addresses per network, by configuring³⁾ the Docker daemon:

/etc/docker/daemon.json
