如何修复Docker ELK堆栈日志tash导入连接错误

Question

我在尝试使用日志存储将 CSV 文件导入到我的弹性搜索实例时遇到问题。我正在使用预配置的Docker ELK堆栈。

当我运行命令时，我的错误如下：

D:\data_sets\logstac config>docker cp CVEimport.conf 80:/

D:\data_sets\logstac config>docker exec -it 80 /bin/bash
bash-4.2$ logstash -f /CVEimport.conf --path.data ./storage/

然后它继续尝试重新连接。

我的配置文件是：

    input {

    file {
        path => ["/CVEDB1.csv"]
        start_position => "beginning"
        sincedb_path => "/dev/null"

    }
}

filter {
        csv {
        columns=> ["Name","Status","Description","References","Phase","Votes","Comments"]
        separator => ","
        }
}

output {

    elasticsearch {
    hosts => "http://127.0.0.1:9200"
    index => "cve"
    user => "elastic"
    password => "changeme"
    }
    stdout{}
}

任何信息都将是有帮助的，因为我是全新的ELK堆栈。

Answer 1

您是否正在运行Elasticsearch REST服务？

# are we green?
curl http://localhost:9200/_cluster/health?pretty

如果要独立测试logstash，可以将输出发送到控制台

# output to console
output {
  stdout { codec => rubydebug }
}

注意。只要您没有保护您的Elasticsearch集群，就不需要用户名和密码。

小说运行泊坞窗时

1. 您可以在host_mode中运行 Elasticsearch
2. 利用 Docker 组合并建立服务发现。
3. curl http://172.16.0.2/_cluster/health?pretty （docker0 subnet）
