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

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

sudo apt-get install docker.io -y && sudo chown $USER /var/run/docker.sock

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.

docker inspect <CONTAINER_ID>

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

docker ps

docker port <container_id>

Thedocker port command specify the port mapping of its containers.

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

docker stats <container_id>

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

docker top <container_id>

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

docker save -o <output_tar_file_name>.tar <image_name>

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

docker load -i <input_tar_file_name>.tar
