The custom secret must contain the required key fluent-bit.yaml and optional included keys, e.g., parsers.conf as shown below.

Sample Secret YAML Definition:

apiVersion: v1
kind: Secret
metadata:
  name: fluent-bit-secret       # Name of the secret
  namespace: your-namespace     # Namespace where the secret will be created
type: Opaque
data:
  fluent-bit.yaml: <base64_encoded_content>
  parsers.conf: <base64_encoded_content>

Example:

Assuming the base64 encoded content of the fluent-bit.yaml file is c29tZS1iYXNlNjQtZW5jb2RlZC1jb250ZW50, the secret would look like this:

apiVersion: v1
kind: Secret
metadata:
  name: fluent-bit-secret       # Name of the secret
  namespace: your-namespace     # Namespace where the secret will be created
type: Opaque
data:
  fluent-bit.yaml: c29tZS1iYXNlNjQtZW5jb2RlZC1jb250ZW50  # Replace with your actual base64 encoded content
parsers.conf: a29tZS1iYXNlNjQtZW5jb2RlZC1jb250ZW51  # Replace with your actual base64 encoded content
