Creating a Docker container

• Process
  
• When we install docker we get two major components
  • docker client
  • docker engine (server)
• To create container user has to execute docker container run <image>
• docker daemon will received this request and checks if the image is present locally.
• If it is not present, it downloads from registry (default registry is docker hub)
• One image is present then the container is created
  

Exercise:

• Create a Docker hub account
• Login into Docker playground
• run the nginx container docker container run nginx
