docker system prune --force should delete stupidly big files popping out of god-damn-nowhere.

disk image location: /Users/davidesqueri/Library/Containers/com.docker.docker/Data/vms/0/data

qui c’è docker.raw che è enorme e contiene tipo tutto quello che serve a docker, era 1.1tb poi ho ridotto la disk size di docker da 1tb a 8gb e adesso è 34gb, ma 0gb on disk.: /Users/davidesqueri/Library/Containers/com.docker.docker/Data/vms/0/data

Le immagini costruite vengono salvate qua su macos:
~/Library/Containers/com.docker.docker/Data/vms/0/
Nota: non c’è una cartella “linux-x86-env” visibile nel filesystem — Docker gestisce tutto dentro un’immagine virtuale (una specie di disco interno del suo ambiente Linux).

Puoi visualizzare dove e quanto spazio occupano le immagini docker con:
docker system df

docker volume ls
docker volume inspect volumeName

Colima

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

colina.yaml:
for persistent, versioned settings, create or edit:
~/.colima/default/colima.yaml

cpu: 4
memory: 8
disk: 20 # GB
vmType: vz  # 'vz' = Apple Virtualization Framework (best for M1/M2/M3)
arch: aarch64
docker:
  runtime: containerd
