# Keycloak containers doesn't come with curl or wget in it, this forces the users to use alternative mechanisms to realise 
# health check for the keycloak standard containers. This example leverages the capability of modern Java to dynamically 
# compile a *.java source file and execute it on the fly using the `java` command. The HealthCheck class uses
# java.net.URL to open a connection to the `health/live` endpoint of keycloak and exits the process with a non-zero status 
# if the http status is not `Ok`

* Shows a message while asserting like: 

ok: [host] => {                  
    "msg": "disk usage 4.2B of total 20.0GB (21.0%) (should exceed limit 90.0%)"
}

* Note this only looks at first mount point on current node
* Fails if disk is near-full
* Last step pushes to a push-based monitoring service, which will alert us if it doesn't get there after some time
* Need to setup a  variable `disk_limit`, which is the max acceptable usage ratio, e.g. set it to 0.8 if you want to keep disks within 80% of max size

Zero knowledge databases

The idea

The idea is to provide a database as a service to end users in such a way that no one except the user herself can access the data, not even the hosting provider or the database administrator.

Advantages

• A privacy- and/or security-conscious user will have more trust in such a setup.
• The service provider cannot be coerced to release the data they were trusted with, and he cannot be held responsible for the content he is storing.
