用于Elasticache Redis集群的aws cdk

Question

我浏览了https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_elasticache.html。

如何使用AWS-CDK创建Elasticache Redis模板。如果您共享示例代码会更有帮助。

很抱歉迟回应，但可以对其他人有用。

CDK没有高级构造来创建Redis集群，但是您可以使用低级构造API来创建它。

对于Redis集群类型，您可以查看以下内容：https://aws.amazon.com/it/blogs/database/work-with-cluster-mode-on-amazon-ellasticache-for-redis/

我使用typescript创建了一个Redis（无复制）集群，如下所示：

const subnetGroup = new CfnSubnetGroup(
  this,
  "RedisClusterPrivateSubnetGroup",
  {
    cacheSubnetGroupName: "privata",
    subnetIds: privateSubnets.subnetIds,
    description: "subnet di sviluppo privata"
  }
);
const redis = new CfnCacheCluster(this, `RedisCluster`, {
  engine: "redis",
  cacheNodeType: "cache.t2.small",
  numCacheNodes: 1,
  clusterName: "redis-sviluppo",
  vpcSecurityGroupIds: [vpc.defaultSecurityGroup.securityGroupId],
  cacheSubnetGroupName: subnetGroup.cacheSubnetGroupName
});
redis.addDependsOn(subnetGroup);

如果您需要一个Redis（集群启用）集群，您可以复制组吗

const redisSubnetGroup = new CfnSubnetGroup(
  this,
  "RedisClusterPrivateSubnetGroup",
  {
    cacheSubnetGroupName: "privata",
    subnetIds: privateSubnets.subnetIds,
    description: "subnet di produzione privata"
  }
);

const redisReplication = new CfnReplicationGroup(
  this,
  `RedisReplicaGroup`,
  {
    engine: "redis",
    cacheNodeType: "cache.m5.xlarge",
    replicasPerNodeGroup: 1,
    numNodeGroups: 3,
    automaticFailoverEnabled: true,
    autoMinorVersionUpgrade: true,
    replicationGroupDescription: "cluster redis di produzione",
    cacheSubnetGroupName: redisSubnetGroup.cacheSubnetGroupName
  }
);
redisReplication.addDependsOn(redisSubnetGroup);

希望这能帮上忙。
