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.

字段 | 必填 | 详情 | Example |
---|---|---|---|
servers | Y | Comma delimited list of servers | “zookeeper.default.svc.cluster.local:2181” |

maxBufferSize | N | The maximum size of buffer. 默认值为 “1048576” | “1048576” |
maxConnBufferSize | N | The maximum size of connection buffer. Defautls to “1048576 “ | “1048576” |
keyPrefixPath | N | The key prefix path in Zookeeper. 无默认值 | “dapr” |
Setup Zookeeper
You can run Zookeeper locally using Docker:
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:
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
