Zookeeper
Setup a Zookeeper state store
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.
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 will install 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
Create a Dapr component
The next step is to create a Dapr component for Zookeeper.
Create the following YAML file named zookeeper.yaml:
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.
Warning
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described here.Apply the configuration
In Kubernetes
To apply the Zookeeper state store to Kubernetes, use the kubectl CLI:
kubectl apply -f zookeeper.yaml
Running locally
To run locally, create a components dir containing the YAML file and provide the path to the dapr run command with the flag --components-path.
