Previously, the Compose file (<code>docker-compose.yml</code>) required a version. Version 2 and version 3 had different options and not all options from version 2 were available in version 3. However, as of docker-compose v1.27+, you should no longer specify a version and options from both versions are supported. | Previously, the Compose file (<code>docker-compose.yml</code>) required a version.

This will force docker to assign subnets from 172.17.0.0/24 to 172.32.255.0/24 instead of 172.17.0.0/12 to 172.32.0.0/12.<br> | |||
Thus it won't overflow to 192.168.0.0/24.<br> | |||
Next, in your firewall, allow connections to your localhost from 172.17.0.0/12. | |||
