# This file defines the default values for all variables
# used in the OpenWhisk Helm Chart.  The variables are grouped
# by component into subtrees.
#
# You _MUST_ override the default value of some of the whisk.ingress variables
# to reflect your specific Kubernetes cluster.  For details, see the appropriate
# one of these files:
#   docs/k8s-docker-for-mac.md
#   docs/k8s-aws.md
#   docs/k8s-ibm-public.md
#   docs/k8s-ibm-private.md
#   docs/k8s-google.md
#   docs/k8s-diy.md (for do-it-yourself clusters).
#
# Production deployments _MUST_ override the default credentials
# that are used in whisk.auth and db.auth.
#
# The file docs/configurationChoices.md discusses other common
# configuration options for OpenWhisk and which variables to override
# to enable them.
#
# The file values-metadata.yaml contains a description of each
# of these variables and must also be updated when any changes are
# made to this file.

# Overall configuration of OpenWhisk deployment
whisk:
  # Ingress defines how to access OpenWhisk from outside the Kubernetes cluster.
  # Only a subset of the values are actually used on any specific type of cluster.
  # See the "Configuring OpenWhisk section" of the docs/k8s-*.md that matches
  # your cluster type for details on what values to provide and how to get them.

# Caveats -
# - You can specify numbers of maxUnavailable Pods for now as integer. % values are not
# supported.
# - minAvailable is not supported
# - PDB only applicable when replicaCount is greater than 1.
# - Only zookeeper, kafka, invoker and controller pods are supported for PDB for now.
