Containerizing Software Applications (DO276) introduces you to deploying applications in containers using Docker and Kubernetes. Learn how to design containers for the deployment of an existing application across multiple containers, build and test those containers using Docker, and deploy the application in a Kubernetes cluster to achieve high availability and load balancing.

Through hands-on labs, students will take a monolithic application and break it down into its distinct services thereby illustrating how containers are an excellent vehicle for microservices architecture deployment.

  • Create containers using Docker
  • Work with image registries
  • Provide persistent storage to a container
  • Create new images using Dockerfiles
  • Implement image design recommended practices
  • Link containers
  • Orchestrate containers using Kubernetes
