Applications database

This is an additional setup if you want to use Teleport for deploying application on a Kubernetes cluster.

Requirements

• A working Kubernetes cluster v1.2.3 >=
• Docker client v1.10.2 >=

No private docker registry is required.

Architecture

A Teleport application is defined by 2 Kubernetes description files:

• controller.yaml: the replication controller configuration.
• service.yaml: the network configuration.

In order to keep those configurations at the same place and accelerate the search of applications we setup a database on the system.

The database is documented-oriented and only have one collection. We are using rethinkdb as database technology. Each document of the collection has the following format

"lastupdate": "2017-01-01T00:00:00.000000+00:00",
"name": "my-app",
"replicationcontroller": {
  "...": "..."
},
"server": "",
"service": {
  "...": "..."
}

Setup

• Install rethinkdb: https://rethinkdb.com/docs/install/
• Start an instance: rethinkdb
• Go to http://localhost:8080 and create a new database infraservices and the collection services for this database.

You are all set ! :)
