Component format

To setup Zookeeper state store create a component of type state.zookeeper. See [this guide]({{< ref "howto-get-save-state.md#step-1-setup-a-state-store" >}}) on how to create and apply a state store configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: state.zookeeper
  version: v1
  metadata:
  - name: servers
    value: <REPLACE-WITH-COMMA-DELIMITED-SERVERS> # Required. Example: "zookeeper.default.svc.cluster.local:2181"
  - name: sessionTimeout
    value: <REPLACE-WITH-SESSION-TIMEOUT> # Required. Example: "5s"
  - name: maxBufferSize
    value: <REPLACE-WITH-MAX-BUFFER-SIZE> # Optional. default: "1048576"
  - name: maxConnBufferSize
    value: <REPLACE-WITH-MAX-CONN-BUFFER-SIZE> # Optional. default: "1048576"
  - name: keyPrefixPath
    value: <REPLACE-WITH-KEY-PREFIX-PATH> # Optional.

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}

Spec metadata fields

Field	Required	Details	Example
servers	Y	Comma delimited list of servers	"zookeeper.default.svc.cluster.local:2181"
sessionTimeout	Y	The session timeout value	"5s"
maxBufferSize	N	The maximum size of buffer. Defaults to "1048576"	"1048576"
maxConnBufferSize	N	The maximum size of connection buffer. Defautls to "1048576"	"1048576"
keyPrefixPath	N	The key prefix path in Zookeeper. No default	"dapr"

Setup Zookeeper

{{< tabs "Self-Hosted" "Kubernetes" >}}

{{% codetab %}} You can run Zookeeper locally using Docker:

docker run --name some-zookeeper --restart always -d zookeeper

You can then interact with the server using localhost:2181. {{% /codetab %}}

{{% codetab %}} The easiest way to install Zookeeper on Kubernetes is by using the Helm chart:

helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
helm install zookeeper incubator/zookeeper

This installs Zookeeper into the default namespace. To interact with Zookeeper, find the service with: kubectl get svc zookeeper.

For example, if installing using the example above, the Zookeeper host address would be:

zookeeper.default.svc.cluster.local:2181 {{% /codetab %}}
