Introduction to the course
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.
In this guide, we'll explore ephemeral environments, which are short-lived, isolated environments for testing, validation, and QA.
We'll be using the Shipyard platform https://shipyard.build to easily set up ephemeral environments for our sample application.
To help Shipyard detect and utilize routes, add a labels field to each of service in the Docker Compose file:
services: react-nginx: labels: shipyard.primary-route: true shipyard.route: "/" # ... api-node: labels: shipyard.route: "/api/node/" shipyard.route.rewrite: true # ... api-golang: labels: shipyard.route: "/api/golang/" shipyard.route.rewrite: true # ...
After pushing these changes to the branch selected above, Shipyard will automatically build your container images and deploy a copy of the application.
