Docker for Developers – Beginners workshop



Docker is the hot new thing, the technology that really brought the DevOps movement to a next level. Every other week a new tool comes out that claims to make Docker easier to use, but information and good advice is often hard to come by.

  • How do containers work?
  • Why use containers and how do they compare to other tools?
  1. Building your first Docker container
  • Running an application in a Docker container
  • Reproducible installations using a Dockerfile
  • Dockerizing your first service
  • How docker layers work
  1. Sharing your containers
  • Using a Docker Registry to share built container images
  • Using a Continuous Integration to build Docker Containers automatically from git
  1. Getting Docker into production
