Colima

self-taught
On macOS docker must run inside a linux VM, the preferred method is to use Colima, which will be the docker Daemon.

brew install colima
colima version
colima status
colima start --auto-start
colima start
colima stop
colima delete # deletes current configuration and settings, must be run to reduce disk size
 
colima ssh # connect to vm
 
# permanent resource limits for colima
colima start --cpu 4 --memory 8 --disk 20
 
docker info | grep -E 'CPUs|Memory'
 
# for persistent, versioned settings, create or edit:
~/.colima/default/colima.yaml
 
colima delete
rm -rf ~/.colima
