Docker
Docker is a software platform that allows you to build, test, and deploy applications quickly.
Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime.
Using Docker, you can quickly deploy and scale applications into any environment and know your code will run.

docker runcommand to start a new container and interact with it through the command line.command:
sudo docker run hello-world
Use the
docker inspectcommand to view detailed information about a container or image.command:
sudo docker inspect [containerID]
Use the
docker portcommand to list the port mappings for a container.command:

Use the
docker statscommand to view resource usage statistics for one or more containers.command:
sudo docker stats [containerID]
Use the
