为什么我在使用 Laravel 和 Docker 时会"No alive nodes found in your cluster"？

Question

我尝试使用Docker和Babenkoivan/Scout-Elasticsearch-Driver在Laravel项目上设置Elasticsearch。当我启动Docker时，所有工作的容器都包括Elasticsearch，但是当我尝试使用

时

php artisan elastic:create-index "AppTutorialIndexConfigurator"

我有一个错误：

No alive nodes found in your cluster

另外，当我尝试通过docker workspace容器的卷发访问端口9200时，我会得到

curl: (7) Failed to connect to localhost port 9200: Connection refused

但是，当我从终端做同样的思考时，我会得到有关Docker Elasticsearch集群的信息。我认为这可能是相关的。

我为这个问题浪费了三天，我没有任何解决方案，请提供帮助。

我试图从劳拉多克和门上做相同的结果。

这是我的docker-compose.yml内容

这是scout_elastic config

<?php
return [
    'client' => [
        'hosts' => [
            env('SCOUT_ELASTIC_HOST', 'localhost:9200'),
        ],
    ],
    'update_mapping' => env('SCOUT_ELASTIC_UPDATE_MAPPING', true),
    'indexer' => env('SCOUT_ELASTIC_INDEXER', 'single'),
    'document_refresh' => env('SCOUT_ELASTIC_DOCUMENT_REFRESH'),
];

和.env Scout config

SCOUT_DRIVER=elastic

我相信您的问题是错误的SCOUT_ELASTIC_HOST
应该是SCOUT_ELASTIC_HOST=http://elasticsearch:9200就像在基巴纳服务中一样。不是http://localhost:9200
