This is a simple web application that just tests a PostgreSQL connection.

It exposes just a few entrypoints:

• /ping pings the database
• /readyz pings the database
• /livez returns 200 if the probe is not failed, otherwise it will raise an internal server error
• /fake set the liveness probe to be faked

This application must not be used as a reference, but it is just meant to explain the meaning of Kubernetes probes.

Some example Kubernetes definitions can be found in the k8s directory.
