How to change docker image folder to HDD?

Docker desktop

• Preferences > Resources > (in Resources Advanced, scroll down) > Disk image location > Browse
• default is ~/Library/Containers/com.docker.docker/Data/vms/0/data
• change to /Volumes/SSD/Docker/vms.0.data
• Sub folder DockerDesktop will be created

Changing location will create a 60GB file named Docker.raw

• will take some time, depending on HDD or SSD
• HDD seems very slow and failed to start
• Need Uninstall - Install again to change to SSD, after tried to use HDD
• Docker.raw file existed in default folder is removed
• remaining files are about 880KB

Q) do I really need docker in M1 Mac ?

[seanshpark]

I can use remote docker host from my Mac.

export DOCKER_HOST=ssh://user@[docker_host_ip]

where docker_host_ip is IP address of Linux machine running dockerd
