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. Defaults to "1048576 "1048576"
keyPrefixPath N The key prefix path in Zookeeper. No default "dapr"

Setup Zookeeper


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 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
