Examine the evolution of virtualization technologies from bare metal, virtual machines, and containers and the tradeoffs between them.
Explores the three core Linux features that enable containers to function (cgroups, namespaces, and union filesystems), as well as the architecture of the Docker components.
Install and configure Docker Desktop
Use publicly available container images in your developer workflows and learn how about container data persistence.
Building out a realistic microservice application to containerize.
Write and optimize Dockerfiles and build container images for the components of the example web app.
Use container registries such as Dockerhub to share and distribute container images.
Use Docker and Docker Compose to run the containerized application from Module 5.
Learn best practices for container image and container runtime security.
Explore how to use Docker to interact with containers, container images, volumes, and networks.
Add tooling and configuration to enable improved developer experience when working with containers.
Deploy containerized applications to production using a variety of approaches.
Final words about the course.
Throughout the course we have interacted with many different Docker objects. This module covers the additional options for how we can work with them.
docker network --help to see all the subcommands associated with Docker networks.
Create a new network:
docker network create my-network
Inspect a network:
docker network inspect my-network
List all networks:
docker network ls
Remove all unused networks:
docker network prune
Remove a specific network:
docker network rm my-network
Connect a container to a network:
docker network connect my-network container-id
Disconnect a container from a network:
docker network disconnect my-network container-id
