元数据字段规范

字段必填详情示例
serversYComma delimited list of servers“zookeeper.default.svc.cluster.local:2181”
sessionTimeoutYThe session timeout value“5s”
maxBufferSizeNThe maximum size of buffer. 默认值为 “1048576”“1048576”
maxConnBufferSizeNThe maximum size of connection buffer. Defautls to “1048576”“1048576”
keyPrefixPathNThe key prefix path in Zookeeper. 无默认值“dapr”

Setup Zookeeper

You can run Zookeeper locally using Docker:

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

然后您可以使用 localhost:2181 与服务器交互。

The easiest way to install Zookeeper on Kubernetes is by using the Helm chart:

  1. helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator
  2. 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
