我正在尝试让docker-compose和django-haystack一起工作。我正在使用以下设置（Web和Elasticsearch在不同的容器中），当我尝试构建我的索引时，会出现错误。
我已经缩小了问题范围，看起来Elasticsearch容器正在按预期工作。然而，Haystack后端无法建立连接。
所有容器：

这是一条命令，用于重新构建索引。WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.
Are you sure you wish to continue? [y/N] y
Removing all documents from your index because you said so.
