========================================================

在容器内部，我可以使用 curl 访问 Elasticsearch。

[elasticsearch@df69f59c016f /]$ curl localhost:9200

{
  "name" : "7l2eIAu",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "FEhCecNWRuOi7qCynVmTrw",
  "version" : {
    "number" : "5.5.0",
    "build_hash" : "260387d",
    "build_date" : "2017-06-30T23:16:05.735Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.0"
  },
  "tagline" : "You Know, for Search"
}
==========================================

但是当我尝试从容器外部卷曲它时，收到以下错误。

[root@ip-20-0-0-86 ~]# curl localhost:9200
curl: (56) Recv failure: Connection reset by peer
[root@ip-20-0-0-86 ~]# curl localhost:9300
curl: (56) Recv failure: Connection reset by peer
[root@ip-20-0-0-86 ~]# curl 127.0.0.1:9300
curl: (56) Recv failure: Connection reset by peer

答案1

publish_address使用您的设置将配置为本地主机：127.0.0.1:9200。

您可以在启动 Elasticsearch 容器时像这样更改相应的设置：

docker run -p 9200:9200 elasticsearch -Ehttp.host=0.0.0.0
