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'm currently running docker desktop version 20.10.22 (build 3a2c30b, fresh install) on Windows (using wsl2), but docker compose commands with the -f flag do not work correctly. Since I'm using docker compose V2 (checked the option in the docker desktop settings), my commands are with a space instead of a hyphen. I get the following message when running any docker compose command using -f:
unknown shorthand flag: 'f' in -f See 'docker --help'.
Specifically, I'm running the FIWARE NGSI-LD tutorials. All docker compose commands that are used within those tutorials fail. The commands can be found in the services file for each tutorial. For example, a command that fails (saying that the -f flag does not exist) within the Short-Term-History tutorial is the following:
docker compose -f docker-compose/mintaka.yml -p fiware up -d --remove-orphans --renew-anon-volumes
The weird thing is that docker compose --help and docker compose --version both return the output from respectively docker --help and docker --version, as if it excludes the compose keyword. The output of the above command also refers to the standard docker help command instead of the docker compose help.
UPDATE: Docker excludes the compose keyword between docker and the rest of the command. Replacing compose with a random string of letters gives the same effect. It seems as if it cannot recognize the compose keyword.
The old docker-compose is not installed so that does not work either. Running which docker-compose returns the docker-compose.exe location, inside the .../Docker/resources/bin folder. Running which docker compose returns the location of docker.exe. The .../Docker/resources/bin folder is inside the path environment variable.
Does anybody know what the problem might be? I've searched countless websites but did not find any solutions for this problem yet.
Kind regards
Here is what I have in running processes when I run docker compose events:
Please check if you have all these directories and files. Then we can troubleshoot further.
I reinstalled docker desktop with the same installer (also same version) and this resolved the problem weirdly enough...
The only difference between my old and new installation was that I already had wsl2 installed this time.
Help me friends, please. I'm a noob in docker.
I'm working with laravel an create project with Docker in location.
root#VIGIA-PC:/mnt/d/projects/fastfood-app/fastfood-api#
docker was working but when I shut down my pc, and then I turn on it, the docker container is not running, why?
when I go to to the project folder and type ls no appear files from debian terminal, when I going to windows they are here.
I runned docker ps and show the follow:
Information
windows version 10
distro linux debian
build 19042
Docker version 20.10.2, build 2291f61
You'll have to change the behavior of your docker apps.
If the host is being restarted, so are the containers running on it : https://docs.docker.com/config/containers/start-containers-automatically/
I have already solved my problem.that was a problem from path
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
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'm using docker Version 1.11.1-beta11 (build: 6974) on OS X (which is native). It has a fancy migration tool to help you to move images from docker-machine to native docker (or something like that). Everything was working perfect, I even was able to start containers through docker-compose but then I rebooted my laptop and now docker-compose is not recognizing new docker engine I guess because I'm getting:
ERROR: Couldn't connect to Docker daemon - you might need to run `docker-machine start default`.
So I believe docker-compose still thinks I'm using or depending on docker-machine to start containers.
Any idea about how to workaround this issue?
Update:
Docker env variables:
DOCKER_TLS_VERIFY=1
DOCKER_HOST=tcp://192.168.99.100:2376
DOCKER_CERT_PATH=/Users/myuser/.docker/machine/machines/default
DOCKER_MACHINE_NAME=default
I removed the docker env variables from my rc script (~/.zshrc) and upgraded docker-compose version to 1.7.1. Also made sure sure docker-machine was down
