Docker for DevOps Engineers #Day-16

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.

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

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

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

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

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

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

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

These tasks involve simple operations that can be used to manage images and containers.

Conclusion

Docker provides a powerful and flexible platform for DevOps engineers to manage and deploy applications efficiently. By mastering essential Docker commands such as docker run, docker inspect, docker port, docker stats, docker top, docker save, and docker load, you can streamline your workflow, ensure consistency across environments, and optimize resource usage. These foundational skills are crucial for leveraging Docker's full potential in modern software development and deployment practices.
