Cannot connect to the Docker daemon on macOS

The Actual problem is..,

I normally prefer to manage my apps on my OSX with brew

I am able to install docker, docker-compose and docker-machine

docker --version
Docker version 17.05.0-ce, build 89658be
docker-compose --version
docker-compose version 1.13.0, build unknown
docker-machine --version
docker-machine version 0.11.0, build 5b27455

I did not download and run ‘Docker for Mac’ app.

However when I try to run

> docker run -d -p 80:80 --name webserver nginx
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.

I have already checked the sock file

ls -lah /var/run/docker.sock /var/tmp/docker.sock
ls: /var/run/docker.sock: No such file or directory
ls: /var/tmp/docker.sock: No such file or directory

I have also tried this proposed solution: Mac OS X sudo docker Cannot connect to the Docker daemon. Is the docker daemon running on this host?

But I got this error message:

$ eval $(docker-machine env default)
Host does not exist: "default"

Is it possible to get a docker service to run by command line tools?

Solution I got to this is,

On a supported Mac, run:

brew install --cask docker

Then launch the Docker app. Click next. It will ask for privileged access. Confirm. A whale icon should appear in the top bar. Click it and wait for “Docker is running” to appear.

You should be able to run docker commands now:

docker ps

Because docker is a system-level package, you cannot install it using brew install, and must use --cask instead.

Note: This solution only works for Macs whose CPUs support virtualization, which may not include old Macs.
