## clusterSize is the initial size of the CouchDB cluster.

## If allowAdminParty is enabled the cluster will start up without any database
## administrator account; i.e., all users will be granted administrative
## access. Otherwise, the system will look for a Secret called
## <ReleaseName>-couchdb containing `adminUsername`, `adminPassword` and
## `cookieAuthSecret` keys. See the `createAdminSecret` flag.
## ref: https://kubernetes.io/docs/concepts/configuration/secret/
allowAdminParty: false

## If createAdminSecret is enabled a Secret called <ReleaseName>-couchdb will
## be created containing auto-generated credentials. Users who prefer to set
## these values themselves have a couple of options:
##
## 1) The `adminUsername`, `adminPassword`, and `cookieAuthSecret` can be
##    defined directly in the chart's values. Note that all of a chart's values
##    are currently stored in plaintext in a ConfigMap in the tiller namespace.
##
## 2) This flag can be disabled and a Secret with the required keys can be
##    created ahead of time.
createAdminSecret: true

adminUsername: admin
# adminPassword: this_is_not_secure
# cookieAuthSecret: neither_is_this

## When enabled, will deploy a networkpolicy that allows CouchDB pods to

## The storage volume used by each Pod in the StatefulSet. If a
## persistentVolume is not enabled, the Pods will use `emptyDir` ephemeral
## local storage. Setting the storageClass attribute to "-" disables dynamic
## provisioning of Persistent Volumes; leaving it unset will invoke the default
## provisioner.

## CouchDB is happy to spin up cluster nodes in parallel, but if you encounter
## problems you can try setting podManagementPolicy to the StatefulSet default

## To better tolerate Node failures, we can prevent Kubernetes scheduler from
## assigning more than one Pod of CouchDB StatefulSet per Node using podAntiAffinity.

## erlangFlags is a map that is passed to the Erlang VM as flags using the
## ERL_FLAGS env. `name` and `setcookie` flags are minimally required to
## establish connectivity between cluster nodes.
