Docker容器HTTP请求限制

我是Docker的新手，所以很可能我缺少一些东西。

我正在使用Elasticsearch使用此图像运行容器。

我能够正确设置所有内容。之后，我使用的是一个由同事开发的脚本，用于插入一些数据，基本上是查询MySQL数据库并发出HTTP请求" title="HTTP请求">HTTP请求。

问题是，这些请求中的许多请求都会卡住，直到失败。如果netstat -tn | grep 9200我知道了：

tcp6 0 0 ::1:58436 ::1:9200 TIME_WAIT tcp6 0 0 ::1:59274 ::1:9200 TIME_WAIT ... tcp6 0 0 ::1:58436 ::1:9200 TIME_WAIT tcp6 0 0 ::1:59274 ::1:9200 TIME_WAIT

有很多要求。在这一点上，我不确定这是否与elasticsearch或泊坞窗有关。如果在我的计算机上安装了Elasticsearch，则不会发生这种情况。

一些信息：

脚本的重要部分：

for package in c.fetchall():
    id_package, tracking_number, order_number, payment_info, shipment_provider_name, package_status_name=package
    el['tracking_number'] = tracking_number
    el['order_number'] = order_number
    el['payment_info'] = payment_info
    el['shipment_provider_name'] = shipment_provider_name
    el['package_status_name'] = package_status_name
    requests.put("http://localhost:9200/packages/package/%s/_create"%(id_package), json=el)
