Docker for DevOps Engineers

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 Commands:

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

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

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

    Eg: docker port CONTAINER [PRIVATE_PORT[/PROTO]]

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