{{/*
This template generates a JSON file with an array containing the names of the
components that the healthcheck container always expects to see--that is, the
components that are enabled in the top-level values.yaml file.
The code loops through the list of components ($components) and checks each component's
entry in the values.yaml file is set to "enabled". It adds the name of each enabled
component to the list.
There is a bit of Helm trickery here--the code uses a dict ($enabled), because that's
apparently the only way to create a variable outside of a range loop that can be updated
from within the range loop. The code here generates a list of the components that are
enabled in values.yaml, and stores it into the list called "enabled" in the dictionary
$enabled.
Note also the assignment to an otherwise unused variable ($x) in the loop. Without that
assignment, the updated value of the $enabled.enabled list would be rendered into the
file each time an enabled component is found.
