Docker is a containerization platform,
Containers are just a processes, limited to what resources they can access, exit when process stops.
Image vs Container:
Image is the binaries, libraries and source code that all make up the application.
Container is the running instance of that image.
Note: We can run many containers with the same image.
In this example we are using open source webserver "nginx".
From where we will get this "nginx" image?
If it is not available locally then it will approach Docekr's default image "registry" is called "Docker Hub" (hub.docker.com), it contains the container images.
