TR;DR - You don’t need to specify a port number when connecting to the AWS managed Elasticsearch service.
That was an easy issue to resolve. While you’re here, let me show you the CloudFormation template that I am using to create a three-node AWS-managed Elasticsearch cluster.
AWSTemplateFormatVersion: 2010-09-09 Description: Elasticsearch Stack Parameters: pAwsAccountId: Type: String Default: 929717587211 Description: AWS Account Id pSourceIP: Type: String Default: 188.8.131.52 Description: IP of the server accessing Elasticsearch Resources: rElasticsearch: Type: AWS::Elasticsearch::Domain Properties: AccessPolicies: Version: 2012-10-17 Statement: - Effect: Allow Principal: AWS: "*" Action: "es:*" Condition: IpAddress: aws:SourceIp: - !Ref pSourceIP Resource: !Join [ "", [ "arn:aws:es:", !Ref "AWS::Region", ":", !Ref "AWS::AccountId", ":domain/", !Ref "AWS::StackName", "/*" ] ] AdvancedOptions: rest.action.multi.allow_explicit_index: true indices.fielddata.cache.size: "" DomainName: !Ref "AWS::StackName" EBSOptions: EBSEnabled: true Iops: 0 VolumeSize: 20 VolumeType: gp2 ElasticsearchClusterConfig: InstanceCount: 3 InstanceType: t2.medium.elasticsearch ElasticsearchVersion: 5.1 Tags: - Key: Name Value: !Join [ ":", [ !Ref "AWS::StackName", elasticsearch ] ] Outputs: oElasticsearchId: Description: the id of elasticsearch Value: !Ref rElasticsearch Export: Name: !Join [ ":", [ !Ref "AWS::StackName", elasticsearch-id ] ] oElasticsearchArn: Description: the arn of elasticsearch Value: !GetAtt rElasticsearch.DomainArn Export: Name: !Join [ ":", [ !Ref "AWS::StackName", elasticsearch-arn ] ] oElasticsearchEndpoint: Description: the endpoint of elasticsearch Value: !GetAtt rElasticsearch.DomainEndpoint Export: Name: !Join [ ":", [ !Ref "AWS::StackName", elasticsearch-endpoint ] ]
As soon as the cluster is in the active state, I can use curl (from the source ip server) to access it.
Get the Endpoint from the Elasticseach console.
