You might want to do this to allocate extra RAM and disk size for Docker (esp. when dealing with large container images)
- Ensure that there's not yet been a Docker machine called 'default' (
docker-machine ls
). If so, you should remove it (docker-machine rm default
).
In theory, you can just create a second machine with a different name. This is not recommended since VirtualBox assigns IP addresses to each machine non-deterministically every time you restart your computer, causing docker-machine to choke on TLS cert-related issues
