Hi, I have this problem, trying to running Docker in Ubuntu 20.04 in windows 11 using the WSL, I installed it using the official documentation in https://docs.docker.com/engine/install/linux-postinstall/, I tried with some commands like:
sudo service docker start | restart
Show me OK but this didn't work when I tried to execute again the run hello-world command.
Can you help me please?
You should install Docker for Windows and manage it from there, rather than a service within WSL. Then in the preferences, you can link it to WSL2, where it'll install the Docker CLI.

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
Has anyone succeeded in running fabric-composer on windows 10 linux sub-system running ubuntu 16.04 ?
You can run composer on windows 10 WSL (windows Subsystem for linux) but you will not be able to run docker containers in it. Linux Docker containers require a linux kernel and WSL doesn't have a linux kernel. It is a clever piece of technology that converts user space Linux API calls dynamically to windows API calls.
Therefore you will have to run hyperledger fabric either by using docker for windows (which runs it for you in hyper-v) or you run your own hypervisor.
It is possible to have the docker commands run in WSL but it will need to configure it to interact with the docker daemon running inside a hypervisor.
Yes, you can use Hyperledger-fabric-composer on windows 10, but as david said in above answer you will not be able to run docker containers directly from Ubuntu sub-system.
To do that you have to do following things:
METHOD:- 1
You will need to install docker CE Client & docker-compose in Ubuntu Subsystem and install Docker(version v17.09) on Windows as well. But those dockers won’t connect together out of the box.
So you need to expose the daemon to port 2375 first by right-clicking the docker icon on task-bar then click setting then check the Expose daemon box.
Now the docker server will be able to connect via Windows network including Ubuntu subsystem. We need to set environment variables in Ubuntu by running below command:
echo "export DOCKER_HOST='tcp://0.0.0.0:2375'" >> ~/.bashrc
source ~/.bashrc
These commands will add DOCKER_HOST to the variables every time we start a new Bash.
METHOD:- 2
If you don't want to use ubuntu sub-system, then you can simply install Git Bash and Docker(version v17.09).
Then install Hyperledger-Fabric by using Git Bash.
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 just install the Windows 10 Anniversary update which has a new feature that linux child system. So I try to run docker in Windows 10 ubuntu bash(linux child system). Why I want to install docker in linux child system is because:
Windows 10 native docker 1.12 need Hyper-V, but Vmware couldn't run if Hyper-V enable. I have a lot images created by Vmware, it isn't so easy to switch to Hyper-v
I don't want to use Docker Toolbox, it need install VirtualBox, just redunant.
apt-get is fine, docker install success, but fail to start.
$ sudo service docker start
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
* Starting Docker: docker [ OK ]
$ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
I have seen this post can-you-run-docker-natively-on-the-new-windows-10-ubuntu-bash-userspace, some people says that it is no posible to run docker in such linux child system, but there also some contrary opinions.
So, I want to ask is there any way to walk around this? Or I have to wait MS update this child system(since it is still beta now).
You have two Problems in there:
the linux child system does not provide the upstart service like e.g. ubuntu. You can work around this by running the docker deamon directly in foreground with docker daemon ...
This does nearly shure not work because docker requires features of the linux kernel like namespaces and capabilities. I don't think the NT-Kernel does implement such exotic features.
