The plan

• Dockerize the IS2 application:
  • a first container for the Spring Boot application
  • a second one for the database
• Deploy both containers in a calm and orderly fashion:
  • Target platforms could be Compose, a cloud provider, etc.

The execution

• Containerization of both the DB and the application was done quite quickly...
• ...having the two containers talk to each other was not.

• We needed to update the way the app reach the database
• Using Docker compose, we need to configure the composition of containers in order for the application to wait for the DB to be ready

Architecture

The results

We manage!

• to deploy using Docker compose
• to deploy on the DCOS Insee platform
• in both cases using images pushed to Docker Hub
• also as a by product, to update the version of Spring boot

Everything is on GitHub! and on Docker hub!

Demo time!

The aftermath

Things to do

• integrate the Spring boot update to the code base
• deploy on a cloud provider, using Kubernetes
• document the work and the lessons learned for WP3?

Outstanding questions

• Initial target was Relais, we ended up with IS2
  • Relais to be proposed as a standalone service ?
• ARC was already dockerized before the hackathon
  • Compare the work done ? Extract some common elements / guide? (Compose / Marathon / Kubernetes)
