как подключиться к http://localhost: 9000 / api / v1 / data от jupyter в docker

Question

Я использую Jupyter в docker. Из моего ноутбука Jupyter я хочу подключиться к API, который доступен через URL http://localhost: 9000 / api / v1 / data .

, если я выполню строки ниже в моем локальном Блокнот jupyter (т.е. не в docker). Я успешно подключился.

import requests
r =requests.get('http://localhost:9000/api/v1/data')
r.status_code

Однако те же строки не будут возвращать ошибку, если будут выполнены в блокноте jupyter в docker. Получающаяся ошибка читает ...

ConnectionError: HTTPConnectionPool(host='localhost', port=9000): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fca3b20bfd0>: Failed to establish a new connection: [Errno 111] Connection refused',))

Я попытался сопоставить порты с 9000 по 9000 в файле YML, который используется для запуска контейнера.

Но ошибка остается.

Answer 1

При обмене данными между docker контейнерами в одном и том же составе вы можете ссылаться на другой контейнер в качестве имени домена, используя его имя.

, так что в вашем случае

import requests
r =requests.get('http://jupyter:9000/api/v1/data')
r.status_code
