What we done so far

• setup Docker for a simple Node.js / MongoDB application

• created image for the application
  • containing all the parts to run the application (runtime Node.js, librairies, application code)

• portable image (dev / test / qa / prod) available through Docker Cloud

• scalability of the application (API)
  • on a single node (for dev / test purposes)
  • on a cluster of Docker hosts
  • on a Docker Swarm
• We also seen several Docker components and how they are integrated together
