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.

Tasks

🔶 Task-1 : docker run

• Use the docker run command to start a new container and interact with it through the command line.

#docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

🔶 Task-2 : docker inspect

• Use the docker inspect command to view detailed information about a container or image.

#docker inspect [OPTIONS] NAME|ID [NAME|ID...]
