如何在minikube中安装Cassandra

在minikube中安装Cassandra可以通过以下步骤完成：

首先，确保已经安装了minikube和kubectl工具，并且minikube已经启动。
创建一个Cassandra的配置文件cassandra.yaml，可以使用以下示例配置：

apiVersion: v1
kind: Service
metadata:
  name: cassandra
spec:
  selector:
    app: cassandra
  ports:
    - protocol: TCP
      port: 9042
      targetPort: 9042
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: cassandra
spec:
  serviceName: cassandra
  replicas: 1
  selector:
    matchLabels:
      app: cassandra
  template:
    metadata:
      labels:
        app: cassandra
    spec:
      containers:
        - name: cassandra
          image: cassandra:latest
          ports:
            - containerPort: 9042
              name: cql
          volumeMounts:
            - name: cassandra-data
              mountPath: /var/lib/cassandra
  volumeClaimTemplates:
    - metadata:
        name: cassandra-data
      spec:
        accessModes: [ "ReadWriteOnce" ]
        resources:
          requests:
            storage: 1Gi

使用kubectl命令创建Cassandra服务和StatefulSet：

kubectl apply -f cassandra.yaml

等待一段时间，直到Cassandra的Pod状态为Running：

kubectl get pods

进入Cassandra的Pod中执行以下命令，创建Cassandra的Keyspace和表：

kubectl exec -it cassandra-0 -- cqlsh
CREATE KEYSPACE mykeyspace WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};
USE mykeyspace;
CREATE TABLE mytable (id UUID PRIMARY KEY, name TEXT);
