用于弹性搜索的开放发行版“源别名不指向写入索引”

Question

我正在使用 open distro for elasticsearch v7.7.0，我想自动管理索引生命周期，因此当创建新索引时，它会自动附加到 ISM 策略。但我收到此错误“源别名未指向写入索引”。

这是我的配置：

1-Logstash 输出

output {
elasticsearch {
hosts => ["http://myelasticsearch"]
user => "someuser"
password => "somepassword-"
#index => "demo"
index => "demo-%{+YYYY.MM.dd.HH-mm}"
       ssl => false
       ssl_certificate_verification => false
       ilm_enabled => false
}
stdout { codec => "dots"}
}

2- ISM 政策

    {
    "policy": {
        "policy_id": "hot warm delete workflow",
        "description": "hot warm delete workflow",
        "last_updated_time": 1595417446751,
        "schema_version": 1,
        "error_notification": null,
        "default_state": "hot",
        "states": [
            {
                "name": "hot",
                "actions": [
                    {
                        "rollover": {
                            "min_index_age": "1d"
                        }
                    }
                ],
                "transitions": [
                    {
                        "state_name": "warm"
                    }
                ]
            },
            {
                "name": "warm",
                "actions": [
                    {
                        "replica_count": {
                            "number_of_replicas": 0
                        }
                    }
                ],
                "transitions": [
                    {
                        "state_name": "delete",
                        "conditions": {
                            "min_index_age": "30d"
                        }
                    }
                ]
            },
            {
                "name": "delete",
                "actions": [
                    {
                        "delete": {}
                    }
                ],
                "transitions": []
            }
        ]
    }
}

3- 索引模板

  PUT _template/my_template
{
"alias": {
    "demo": {"is_write_index": true }
  },
  "index_patterns": ["demo*"],                 
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 1,
    "opendistro.index_state_management.policy_id": "hot warm delete workflow",      
    "opendistro.index_state_management.rollover_alias": "demo"  
    
  }
}

我注意到，创建别名时它没有获得 'is_write_index": true' 属性。

任何有用的评论将不胜感激。

我自己解决了这个问题。

对于面临同样问题的人来说，这里是解决方案。

1-首先创建一个模板：

PUT _template/my_template
{
  "index_patterns": ["demo*"],                 
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 1,
    "opendistro.index_state_management.policy_id": "hot warm delete workflow",      
    "opendistro.index_state_management.rollover_alias": "demo"  
    
  }
}

2- 您需要引导初始索引并将其指定为索引模板中指定的翻转别名的写入索引：

PUT demo-000001
{
  "aliases": {
    "demo": {
      "is_write_index": true
    }
  }
}

3-Logstash 输出：

output {
elasticsearch {
hosts => ["http://myelasticsearch"]
user => "someuser"
password => "somepassword-"
index => "demo"
       ssl => false
       ssl_certificate_verification => false
       ilm_enabled => false      
}
stdout { codec => "dots"}
}
