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

I'm afraid you need to add docker command to your PATH manually. It can be done through profile file. As ZSH is now a default shell on MacOS, it would go to ~/.zprofile file:

# Add Visual Studio Code (code)
export PATH="$PATH:/Applications/Visual Studio Code.app/Contents/Resources/app/bin"
# Add Docker Desktop for Mac (docker)
export PATH="$PATH:/Applications/Docker.app/Contents/Resources/bin/"

Answer 4

If you successfully installed docker using the official package, the command should be available under /usr/local/bin/docker .

That directory might not yet be in your $PATH, so you could try adding it, run:

export PATH="/usr/local/bin:$PATH"

this adds /usr/local/bin to the front of your PATH .

Detais:

Check docker is not there:

docker
zsh: command not found: docker

Check what PATH is:

echo $PATH
/Users/brandomiranda/.opam/__coq-platform.2022.01.0~8.15~beta1/bin:/Users/brandomiranda/opt/anaconda3/envs/meta_learning/bin:/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin

Then add PATH (To set it for current shell and all processes started from current shell use export ):

export PATH="/usr/local/bin:$PATH"

Check what I added to Path:

echo $PATH
/usr/local/bin:/Users/brandomiranda/.opam/__coq-platform.2022.01.0~8.15~beta1/bin:/Users/brandomiranda/opt/anaconda3/envs/meta_learning/bin:/opt/homebrew/bin:/usr/bin:/bin:/usr/sbin:/sbin

Seems that /usr/local/bin wasn't in my path. Probably odd? Seems odd to me...why isn't it there?

Answer 6

This command helped me:

/Applications/Docker.app/Contents/Resources/bin/docker --version

Check version after that:

docker --version

Answer 7

Homebrew's docker doesn't install /usr/local/bin/docker or the /Applications/Docker.app any more on 10.13.

You have to download the Docker Desktop for Mac application from the docker.com site above and install it.

Answer 8

You can also install docker with following command on Mac :

brew install docker-machine docker

Answer 9

So to install images, instead of

/bin/docker run -d -p 80:80 docker/getting-started

use

/Applications/Docker.app/Contents/Resources/bin/docker run -d -p 80:80 docker/getting-started

Answer 10

There's is likely a better solution but this worked for me (macOS):

Edit your .zshrc or .bashrc , depending on which one you use

vi ~/.zshrc # or ~/.bashrc

In my case .zshrc

# ~/.zshrc
...

alias docker="/Applications/Docker.app/Contents/Resources/bin/docker"

...

source ~/.zshrc

this should work now

docker --version

This works because we're aliasing docker to the executable located in /Applications/Docker.app/Contents/Resources/bin/docker .
