To run `docker` on the host (assumes docker-cli is installed), run the following commands:
------
docker context create lima --docker "host=unix://{{.Dir}}/sock/docker.sock"
docker context use lima

This seems not to work. Seems that the socket is not on user level.
default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock swarm
So I changed the portForwards:
portForwards:
- guestSocket: "/var/run/docker.sock"
hostSocket: "{{.Dir}}/sock/docker.sock"
But when I set the docker context
to the lima vm (the socket available in .lima
folder) it doesn't work.
With docker ps
->
error during connect: Get "<http://%2FUsers%2FUSER%2F.lima%2Fdocker_x86_64_root%2Fsock%2Fdocker.sock/v1.24/containers/json?all=1>": EOF

With other vms it's working. When using limactl shell docker_x86_64_root
then using the sudo docker ps
is working without issues. Something not allowed on the guest?# Example to use Docker instead of containerd & nerdctl
