## 2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. **This also works for Docker for Windows for getting in Moby Linux VM** (doesn't work for Windows Containers).

`docker run -it --rm --privileged --pid=host justincormack/nsenter1`

## Option 1 (hard way): use netcat

`nc -U ~/Library/Containers/com.docker.docker/Data/debug-shell.sock`

Exit the shell with `exit`.

## Option 2 (easier): Use nsenter in priviledged container

`docker run -it --privileged --pid=host debian nsenter -t 1 -m -u -n -i sh`

Phil Estes (Docker Maintainer) says:

> it’s running a container (using the debian image. nothing special about it other than it apparently has 
`nsenter` installed), with pid=host (so you are in the process space of the mini VM running Docker4Mac), 
and then nsenter says “whatever is pid 1, use that as context, and enter all the namespaces of that, and run a shell there"

## Option 3 (easist): run nsenter from a pre-built image. From Justin Cormack (Docker Maintainer)

`docker run -it --rm --privileged --pid=host justincormack/nsenter1`
