查找elasticsearch服务端点

Question

我正在进行测试，测试弹性云。但是现在我在创建从logstash到弹性云的管道时遇到了问题。下面是我的logstash.conf输出

output {
        stdout{codec=>rubydebug}
        elasticsearch
        {
            hosts=>["https://<clusterid>.asia-southeast1.gcp.cloud.es.io:9243"]
 index=>"testindex"
user=>elasticdeploymentcredentials
password=>elasticdeploymentcredentials
 }
}

但它总是返回以下错误：

[WARN ] 2021-03-29 12:24:50.148 [Ruby-0-Thread-9: :1] elasticsearch - Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"https://elastic:xxxxxx@<clusterid>.asia-southeast1.gcp.cloud.es.io:9243/", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [https://elastic:xxxxxx@<clusterid>.asia-southeast1.gcp.cloud.es.io:9243/][Manticore::ResolutionFailure] <clusterid>.asia-southeast1.gcp.cloud.es.io"}

我可以使用我的凭证卷曲它，如下所示：[root@localhost testconfig]# curl https://elasticdeploymentcredentials:elasticdeploymentcredentials@<clusterid>.asia-southeast1.gcp.elastic-cloud.com:9243 It returning

  "name" : "name",
  "cluster_name" : "<clusterid>",
  "cluster_uuid" : "<clusteruuid>",
  "version" : {
    "number" : "7.12.0",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "build_hash",
    "build_date" : "2021-03-18T06:17:15.410153305Z",
    "build_snapshot" : false,
    "lucene_version" : "8.8.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

我是不是遗漏了什么？

尝试使用Cloud_ID/ Cloud _Auth组合，而不是尝试通过用户名/密码从展开连接到Elastic Cloud：

output {
  elasticsearch {
    hosts => ["https://<clusterid>.asia-southeast1.gcp.cloud.es.io:9243"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    cloud_id => "your cloudid from the console"
    cloud_auth => "elastic:password"
  }
}

cloud_auth参数是您实际要使用部署中的用户名/密码的位置。更多信息请点击此处：
