Docker is a full development platform for creating containerized applications. Docker Desktop is the best way to get started with Docker on Windows.

1 – Download and Install from below url

https://docs.docker.com/docker-for-windows/install/

2 – Open a terminal window (Command Prompt or PowerShell, but not PowerShell ISE).

3 – Run docker --version to ensure that you have a supported version of Docker:

4 – Pull the hello-world image from Docker Hub and run a container:

> docker run hello-world

docker : Unable to find image 'hello-world:latest' locally
...

latest:
Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.
...

5 – List the hello-world image that was downloaded from Docker Hub:

> docker image ls

6 – Explore the Docker help pages by running some help commands:

> docker --help
> docker container --help
> docker container ls --help
> docker run --help

Sample Complex Applications

In this section, demonstrated sample the ease and power of Dockerized applications by running something more complex, such as an OS and a webserver.

1. Pull an image of the Ubuntu OS and run an interactive terminal inside the spawned container: > docker run --interactive --tty ubuntu bash

docker run --interactive --tty ubuntu bash

 docker : Unable to find image 'ubuntu:latest' locally
 ...

 latest:
 Pulling from library/ubuntu

 Pulling fs layer

 Status: Downloaded newer image for ubuntu:latest

You are in the container. At the root # prompt, check the hostname of the container:

 root@8aea0acb7423:/# hostname
 8aea0acb7423

Notice that the hostname is assigned as the container ID (and is also used in the prompt).

Exit the shell with the exit command (which also stops the container):

List containers with the --all option (because no containers are running).

The hello-world container (randomly named, relaxed_sammet) stopped after displaying its message. The ubuntu container (randomly named, laughing_kowalevski) stopped when you exited the container.

docker container ls --all

 CONTAINER ID    IMAGE          COMMAND     CREATED          STATUS                      PORTS    NAMES

 45f77eb48e78    hello-world    "/hello"    3 minutes ago    Exited (0) 3 minutes ago             relaxed_sammet

Pull and run a Dockerized nginx web server that we name, webserver:

docker run --detach --publish 80:80 --name webserver nginx

 Unable to find image 'nginx:latest' locally
 latest: Pulling from library/nginx

Point your web browser at http://localhost to display the nginx start page. (You don’t need to append :80 because you specified the default HTTP port in the docker command.)

List only your running containers:

docker container ls

 CONTAINER ID    IMAGE    COMMAND                   CREATED          STATUS          PORTS                 NAMES
 0e788d8e4dfd    nginx    "nginx -g 'daemon of…"    2 minutes ago    Up 2 minutes    0.0.0.0:80->80/tcp    webserver

Stop the running nginx container by the name we assigned it, webserver:

 >  docker container stop webserver

Remove all three containers by their names — the latter two names will differ for you:

> docker container rm webserver laughing_kowalevski relaxed_sammet
