如何在minikube中安装Cassandra

Question

我想知道是否有办法在minikube中本地安装Cassandra集群。我找到了一些解决方案，只是要将其安装在GCP等云供应商中，但是我需要在我的开发环境中安装。

Answer 1

我能够在Ubuntu helm charts上运行k8s v1.9.2的minikube v1.17.4中使用16.04 Xenial安装cassandra：

git clone [email protected]:helm/charts.git
cd charts
kubectl create ns cassandra
helm install cassandra --namespace "cassandra" incubator/cassandra

$ kubectl get pods,svc -n=cassandra
NAME              READY   STATUS    RESTARTS   AGE
pod/cassandra-0   1/1     Running   0          3m52s
pod/cassandra-1   0/1     Running   0          104s
NAME                TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                                        AGE
service/cassandra   ClusterIP   None         <none>        7000/TCP,7001/TCP,7199/TCP,9042/TCP,9160/TCP   3m52s

## see status of cassandra cluster
$ kubectl exec -it --namespace cassandra cassandra-0 nodetool status
