I can check if docker is installed through the which docker or command -v docker commands. But I need to check if docker's compose plugin is installed (I will use it like docker compose up -d later).
Write on terminal:
$ docker compose --version
The return would look like:
Docker version X.Y.Z, build 95e78f4241
Source: https://docs.docker.com/engine/reference/commandline/compose/
For me it worked a little bit differently, docker compose --version just gave me the CLI options of docker.
hotfix#localhost:~$ docker -v
Docker version 23.0.1, build a5ee5b1
hotfix#localhost:~$ docker compose version
Docker Compose version v2.16.0
I am using Ubuntu 22.04.01 LTS and I followed these instructions from Docker for installation.
⚠️ Note
Beware that Docker is currently transitioning from Compose v1 to v2. The older version is called docker-compose which version you can check with:
docker-compose --version
You can just check for docker-compose version docker-compose --version
If docker-compose is not installed, It will throw an error docker-compose in unrecognized.

I installed docker with the instructions here, downloading from docker-hub
https://docs.docker.com/docker-for-mac/install/
But when I run docker-compose I get this error
pyenv: docker-compose: command not found
The `docker-compose' command exists in these Python versions:
3.6.5/envs/myenv
Also, docker-compose is available under /Users
which docker-compose
/Users/<username>/.pyenv/shims/docker-compose
In this link says, docker-compose for mac need not be installed explicitly as it is part of docker for desktop mac.
https://docs.docker.com/compose/install/
Is something wrong with my installation?
I ran into the same issue on macOS today. Turned out that you need to run the installed app once, it does some additional downloading and setup. That setup includes setting up your path variables.
docker-compose is a utility that is now a parameter in mac docker
so instead of docker-compose up, its now docker compose up
if you install docker from official website then docker-compose will come along with that for mac so need to either upgrade and documentation is present there.
I want to install docker using command line not using docker for mac. I have downloaded the individual binary for Mac from this link.
docker ce binaries
I am able to run docker command but if I run docker ps then it shows
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
I tried another way to downloading docker using brew as below
brew cask install docker
But using brew it only download the desktop setup of docker and I have to start it manually.
So I am looking for a solution in which I can install and run docker through command without involving any UI.
Thanks
The error above means that the docker service is not running so you have to run it first. Then enable it to start on boot - to avoid the need to start it each time you login to your macOS - at the end you should be able to use docker cli without issues
On the beta release of the docker app, you get docker-compose version 1.11.1, which only supports file version 2.0 (that is, the docker-compose file has 'version: "2"' at the top).
There are a few features that I would love to use from 2.1+, but it seems docker for mac is a bit behind.
Is there a way for me to use 2.1+ on a mac, or am I just going to have to wait for the 1.12 docker-compose release on mac?
The latest Docker for Mac (non beta) supports the 2.1 compose file features.
You may be confusing Docker Compose and Docker Engine versions.
A version 2.1 compose file requires a Docker Engine running 1.12.0+ and I can't find a documented Compose version requirement, but it works with Docker Compose 1.10+ here.

It is possible to install Microsoft CNTK on a macbook? I have OS X El Capitan. The official Microsoft documentation at https://github.com/Microsoft/CNTK/wiki/Setup-CNTK-on-your-machine doesn't provide any information for mac users.
Thank you
As of June 2017, you can only run CNTK on OSX using Docker (which will run a Linux container)
Documentation from Microsoft is available here: https://learn.microsoft.com/en-us/cognitive-toolkit/CNTK-Docker-Containers
If you want to run the CPU version of CNTK (as opposed to a GPU enabled) you'll need to pull a particular version of the docker container. See: https://hub.docker.com/r/microsoft/cntk/
I recommend using the following for CPU CNTK:
docker pull microsoft/cntk:2.0-cpu-python3.5
Once you've pulled the container above, you can use Jupyter Notebooks to look at tutorials etc:
First, run the container:
docker run -d -p 8888:8888 --name cntk-jupyter-notebooks -t microsoft/cntk:2.0-cpu-python3.5
Then run this command:
docker exec -it cntk-jupyter-notebooks bash -c "source /cntk/activate-cntk && jupyter-notebook --no-browser --port=8888 --ip=0.0.0.0 --notebook-dir=/cntk/Tutorials --allow-root"
You'll want to access the shell to run CNTK commands. You can attach a bash shell using docker.
Get your container id
docker ps
Then attach a shell
docker exec -it <container_id> bash
While it might not be supported on Mac directly, you can always use a virtual machine to get around.
You can setup docker in your local environment.
https://docs.docker.com/docker-for-mac/
Follow its documentations on how to install on Docker
https://github.com/Microsoft/CNTK/wiki/CNTK-Docker-Containers
We currently support both Linux and Windows. Mac support is on our ToDo or would be interested in community contribution.
I'm currently building CNTK on a linux machine without root access, installing every dependency with linuxbrew (a fork of homebrew). So I think is possible to build on MacOS natively. You can try building it from source with CNTK linux manual to build from source. Let me know if you have any issue.
I have Docker Toolbox installed under Windows 7. The Docker daemon is running inside a VM (the default behavior of Docker Toolbox).
I am trying to get Phundament running using the default tutorial.
It all works fine until I reach this command:
docker-compose run php composer install
It results in:
I've successfully attached to the running container using docker exec -it <container ID> bash but when I do a ls /app command on any of the two containers I get no files in that directory. In effect, the attempt to run composer install there fails.
I tried attaching to both containers and the result is identical.
I also noticed that behavior just recently, it's sadly a limitation of docker-compose on Windows.
For the command you mentioned you can actually run
docker-compose run -d php composer install
As general workarounds...
use docker exec -it app_php_1 bash
see also https://getcarina.com/docs/troubleshooting/troubleshooting-cannot-enable-tty-mode-on-windows/
if you don't really need an interactive shell, you could just run a command or script, like docker-compose run -d php setup.sh
Note: I need to double-check the above suggestions on a real Windows testing system.
PS: I am the author if Phundament. I've also just created an issue for this.
Please try:
winpty docker-compose run php composer install
it works for example:
winpty docker run --rm -it debian bash
