## Additional env variables
## CUSTOM_SCRIPT_PATH is the path of the custom shell script to be ran mounted in a volume

  # We usually recommend not to specify default resources and to leave this as a conscious
  # choice for the user. This also increases chances charts run on environments with little
  # resources, such as Minikube. If you do want to specify resources, uncomment the following
  # lines, adjust them as necessary, and remove the curly braces after 'resources:'.

  #  cpu: 100m

## You can list load balanced service endpoint, or list of all brokers (which is hard in K8s).  e.g.:
## bootstrapServers: "PLAINTEXT://dozing-prawn-kafka-headless:9092"
kafka:
  bootstrapServers: ""

## If the Kafka Chart is disabled a URL and port are required to connect
## e.g. gnoble-panther-cp-schema-registry:8081
cp-schema-registry:
  url: ""

## List of volumeMounts for connect server container

## List of volumeMounts for connect server container
## ref: https://kubernetes.io/docs/concepts/storage/volumes/
volumes:
# - name: credentials
#   secret:
#     secretName: creds

## Secret with multiple keys to serve the purpose of multiple secrets
## Values for all the keys will be base64 encoded when the Secret is created or updated
## ref: https://kubernetes.io/docs/concepts/configuration/secret/
secrets:
  # username: kafka123
  # password: connect321

## These values are used only when "customEnv.CUSTOM_SCRIPT_PATH" is defined.
## "livenessProbe" is required only for the edge cases where the custom script to be ran takes too much time
## and errors by the ENTRYPOINT are ignored by the container
## As an example such a similar script is added to "cp-helm-charts/examples/create-connectors.sh"
## ref: https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/
livenessProbe:
  # httpGet:

  #   port: 8083
  # initialDelaySeconds: 30
  # periodSeconds: 5
