Docker command not found when running on Mac

Question

I'm trying to run the below code as instructed in the docker-graphite-statsd:

docker run -d\
 --name graphite\
 --restart=always\
 -p 80:80\
 -p 2003-2004:2003-2004\
 -p 2023-2024:2023-2024\
 -p 8125:8125/udp\
 -p 8126:8126\
 graphiteapp/graphite-statsd

It gives this error:

$ sudo docker run -d --name graphite --restart=always -p 80:80 -p 2003-2004:2003-2004 -p 2023-2024:2023-2024 -p 8125:8125/udp -p 8126:8126 graphiteapp/graphite-statsd
sudo: docker: command not found

This is on a Mac. I tried brew install docker but it made no difference.

How do I resolve this?

Answer 1

After installing docker using Homebrew, start the Docker daemon by searching for Docker in the Application folder in Finder and running it.

I had to run the following from terminal after doing the above: docker run -d -p 80:80 docker/getting-started

Now run "docker --version" from terminal and it should give the desired result.
