What is docker ?

Docker is a comprehensive software platform designed to facilitate the swift building, testing, and deployment of applications. It achieves this by encapsulating software into standardized units known as containers, each containing all the necessary components for the software to run seamlessly. These components include libraries, system tools, code, and runtime. With Docker, you can efficiently deploy and scale applications across diverse environments, ensuring the predictability and reliability of your code execution.

Docker simplifies the process of deploying and managing applications, making it a popular choice for developers and operations teams looking to improve consistency, efficiency, and collaboration in software development and deployment.

Tasks

As we have already installed Docker in previous days tasks, now is the time to run Docker commands.

1. Use the docker run command to start a new container and interact with it through the command line. [Hint: docker run hello-world]

   

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

   

3. Use the docker port command to list the port mappings for a container.

   

   Here we checked port details for nginx. we have checked process details using ps -a and we got the container id for nginx.

4. Use the docker stats command to view resource usage statistics for one or more containers.

   

   

5. Use the docker top command to view the processes running inside a container.

   

6. Use the docker save command to save an image to a tar archive.

   

   We could see that image has been stored as a .tar file on the local system.

7. Use the docker load command to load an image from a tar archive.

   

   These tasks encompass straightforward operations for the management of images and containers.
