What You'll Learn

This training focuses on a dev/devops perspective. You start from packaging your application (with whatever language you use) then run your complete stack (with db, proxy, loadbalancer) all in containers, to reach dev-prod parity.

  • Understand containerization concepts and Docker architecture
  • Build efficient Docker images using best practices
  • Manage containers, networks, and volumes effectively
  • Create multi-container applications with Docker Compose
  • Deploy containerized applications to dev/test/production
  • Design container-native application architectures
