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 inspectcommand to view detailed information about a container or image.
docker inspect <CONTAINER_ID>
- Use the
docker portcommand 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 statscommand to view resource usage statistics for one or more containers.
docker stats <container_id>
- Use the
docker topcommand to view the processes running inside a container.
docker top <container_id>
- Use the
docker savecommand to save an image to a tar archive.
docker save -o <output_tar_file_name>.tar <image_name>
- Use the
docker loadcommand to load an image from a tar archive.
docker load -i <input_tar_file_name>.tar
