  ##
  pathType: ImplementationSpecific
  ## @param ingress.apiVersion Force Ingress API version (automatically detected if not set)
  ##
  apiVersion: ""
  ## @param ingress.hostname Default host for the ingress record
  ##
  hostname: clickhouse.local
  ## @param ingress.ingressClassName IngressClass that will be be used to implement the Ingress (Kubernetes 1.18+)
  ## This is supported in Kubernetes 1.18+ and required if you have more than one IngressClass marked as the default for your cluster .
  ## ref: https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/
  ##
  ingressClassName: ""
  ## @param ingress.path Default path for the ingress record
  ## NOTE: You may need to set this to '/*' in order to use this with ALB ingress controllers
  ##
  path: /
  ## @param ingress.annotations Additional annotations for the Ingress resource. To enable certificate autogeneration, place here your cert-manager annotations.
  ## Use this parameter to set the required annotations for cert-manager, see
  ## ref: https://cert-manager.io/docs/usage/ingress/#supported-annotations
  ## e.g:
  ## annotations:
  ##   kubernetes.io/ingress.class: nginx
  ##   cert-manager.io/cluster-issuer: cluster-issuer-name
  ##
  annotations: {}
  ## @param ingress.tls Enable TLS configuration for the host defined at `ingress.hostname` parameter
  ## TLS certificates will be retrieved from a TLS secret with name: `{{- printf "%s-tls" .Values.ingress.hostname }}`
  ## You can:
  ##   - Use the `ingress.secrets` parameter to create this TLS secret
  ##   - Rely on cert-manager to create it by setting the corresponding annotations
  ##   - Rely on Helm to create self-signed certificates by setting `ingress.selfSigned=true`
  ##
  tls: false
  ## @param ingress.selfSigned Create a TLS secret for this ingress record using self-signed certificates generated by Helm
  ##
  selfSigned: false
  ## @param ingress.extraHosts An array with additional hostname(s) to be covered with the ingress record
  ## e.g:
  ## extraHosts:

  ## - hosts:
  ##     - clickhouse.local
  ##   secretName: clickhouse.local-tls
  ##
  extraTls: []
  ## @param ingress.secrets Custom TLS certificates as secrets
  ## NOTE: 'key' and 'certificate' are expected in PEM format
  ## NOTE: 'name' should line up with a 'secretName' set further up
  ## If it is not set and you're using cert-manager, this is unneeded, as it will create a secret for you with valid certificates
  ## If it is not set and you're NOT using cert-manager either, self-signed certificates will be created valid for 365 days
  ## It is also possible to create and manage the certificates outside of this helm chart
  ## Please see README.md for more information
  ## e.g:
  ## secrets:
  ##   - name: clickhouse.local-tls
  ##     key: |-
  ##       -----BEGIN RSA PRIVATE KEY-----
  ##       ...
  ##       -----END RSA PRIVATE KEY-----

  ## NOTE: when runAsUser is set to special value "auto", init container will try to chown the
  ##   data folder to auto-determined user&group, using commands: `id -u`:`id -G | cut -d" " -f2`
