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
