Get started with Docker for Windows

Welcome to Docker for Windows!

Docker is a full development platform for creating containerized apps, and Docker for Windows is the best way to get started with Docker on Windows systems.

Got Docker for Windows? If you have not yet installed Docker for Windows, please see Install Docker for Windowsfor an explanation of stable  and edge channels, system requirements, and download/install information.

Looking for system requirements? Check out What to know before you install, which has moved to the new install topic.

Check versions of Docker Engine, Compose, and Machine

Start your favorite shell (cmd.exe, PowerShell, or other) to check your versions of docker and docker-compose, and verify the installation.

PS C:\Users\Docker> docker --version
Docker version 17.03.0-ce, build 60ccb22 PS C:\Users\Docker> docker-compose --version
docker-compose version 1.11.2, build dfed245 PS C:\Users\Docker> docker-machine --version
docker-machine version 0.10.0, build 76ed2a6

Explore the application and run examples

The next few steps take you through some examples. These are just suggestions for ways to experiment with Docker on your system, check version information, and make sure docker commands are working properly.

  1. Open a shell (cmd.exe, PowerShell, or other).

  2. Run some Docker commands, such as docker psdocker version, and docker info.

    Here is the output of docker ps run in a powershell. (In this example, no containers are running yet.)

    PS C:\Users\jdoe> docker ps
    
    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

    Here is an example of command output for docker version.

    PS C:\Users\Docker> docker version

    Note: The outputs above are examples. Your output for commands like docker version and docker infowill vary depending on your product versions (e.g., as you install newer versions).

  3. Run docker run hello-world to test pulling an image from Docker Hub and starting a container.

    PS C:\Users\jdoe> docker run hello-world
    
    Hello from Docker.
    This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
  4. Try something more ambitious, and run an Ubuntu container with this command.

    PS C:\Users\jdoe> docker run -it ubuntu bash

    This will download the ubuntu container image and start it. Here is the output of running this command in a powershell.

    PS C:\Users\jdoe> docker run -it ubuntu bash
    
    Unable to find image 'ubuntu:latest' locally
    latest: Pulling from library/ubuntu
    5a132a7e7af1: Pull complete
    fd2731e4c50c: Pull complete
    28a2f68d1120: Pull complete

    Status: Downloaded newer image for ubuntu:latest

    Type exit to stop the container and close the powershell.

  5. Start a Dockerized webserver with this command:

    PS C:\Users\jdoe> docker run -d -p 80:80 --name webserver nginx

    This will download the nginx container image and start it. Here is the output of running this command in a powershell.

    PS C:\Users\jdoe> docker run -d -p 80:80 --name webserver nginx
    
    Unable to find image 'nginx:latest' locally
    latest: Pulling from library/nginx fdd5d7827f33: Pull complete
    a3ed95caeb02: Pull complete
    716f7a5f3082: Pull complete

    Status: Downloaded newer image for nginx:latest

Point your web browser at http://localhost to display the start page.

(Since you specified the default HTTP port, it isn’t necessary to append :80 at the end of the URL.)

Get started with Docker for Windows

  1. Run docker ps while your webserver is running to see details on the container.

    PS C:\Users\jdoe> docker ps
    
    CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS
    NAMES
    dfe13c68b3b8 nginx "nginx -g 'daemon off" 3 days ago Up 45 seconds 0.0.0.0:80->80/tcp, 443/tc
    p webserver

Stop or remove containers and images.

The nginx webserver will continue to run in the container on that port until you stop and/or remove the container. If you want to stop the webserver, type: docker stop webserver and start it again with docker start webserver.

To stop and remove the running container with a single command, type: docker rm -f webserver. This will remove the container, but not the nginx image. You can list local images with docker images. You might want to keep some images around so that you don’t have to pull them again from Docker Hub. To remove an image you no longer need, use docker rmi followed by an image ID or image name. For example, docker rmi nginx.
