3. Start docker desktop for windows
4. Test your installation
   • open a terminal window (command prompt)
   • run docker --version to ensure that you have a support version of docker

      > docker --version
     

   • pull the hello-world image from docker hub and run a container

      > docker run hello-world
     

   • list the hello-world image that was downloaded from docker hub

      > docker image ls
     

   • list the hello-world container(thar exited after displaying “hello from docker!”)

      > docker container ls --all
     

Explore the application

1. ubuntu os
   • pull an image of the ubuntu OS and run an interactive terminal inside the spawned container

      > docker run --interactive --tty ubuntu bash 
      or
      > docker run -it ubuntu bash
     

   • you are in the container. At the root # prompt, check the hostname of the container

      root@:/ # hostname
      root@:/ # exit
      >
     

   • list containers with the –all option

      > docker container ls --all
     

2. nginx webserver
   • pull and run a Dockerized nginx web server that we name, webserver:

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

   • point your web browser at http://localhost to display the nginx start page
   • List only your running containers:

      > docker container ls
     

   • stop the running nginx container by the name we assigned it, webserver

      >  docker container stop webserver
     

   • remove all three containers by their names:

      > docker container rm webserver
     

Getting Started with Docker

1. Part 1: Orientation and setup
   • docker concepts
     • images and containers: a container is launched by running an image
image is an executable package that includes everything needed to run an application
       container is a runtime instance of an image
     • Containers and virtual machines
       container runs natively on linux and shares the kernel of the host machine with other containers.
       virtual machine runs a full-blown ‘guest’ operating system with virtual access to host resources through a hypervisor.
