Datasource variable
This example shows how to reference values from a secret in data source fields.
Values can be assigned using spec.valuesFrom:
valuesFrom:
- targetPath: "secureJsonData.httpHeaderValue1"
valueFrom:
secretKeyRef:
name: "credentials"
key: "PROMETHEUS_TOKEN"
The Operator will look for a key with the name PROMETHEUS_TOKEN in a secret with the name credentials.
It will then inject the value into secureJsonData.httpHeaderValue1:
datasource:
secureJsonData:
"httpHeaderValue1": "Bearer ${PROMETHEUS_TOKEN}"
The Operator expects a string to be present with the replacement pattern.
