sentestemail 在 GCE docker-compose 上失敗

我正在 Google Cloud Platform 上設置 Weblate（使用 Container-Optimized OS 的 GCE）並通過docker-compose使用 HTTPS 配置進行部署。

我遵循了這些教程：

• Weblate：使用 Docker 安裝
• Google：使用 Docker 執行 Docker Compose

Weblate 執行良好，但是由於以下原因無法發送電子郵件：

ERROR Handled exception: OSError: [Errno 99] Cannot assign requested address

OSError: [Errno 99] Cannot assign requested address

我嘗試過使用docker-compose-https.override.yml文件中的各種設置，即省略某些設置以自動配置和更改指定的電子郵件地址、指定郵件埠以及更改 SSL/TLS 設置。

以下是配置的相關部分：

...
WEBLATE_EMAIL_HOST: "smtp-relay.gmail.com"
WEBLATE_SERVER_EMAIL: "weblate@example.org"
WEBLATE_DEFAULT_FROM_EMAIL: "weblate@example.org"
WEBLATE_USE_SSL: 0
WEBLATE_USE_TLS: 1
WEBLATE_ALLOWED_HOSTS: "i18n.example.org"
...

我不確定問題是什麼或在哪裡尋找解決它。

我再次嘗試了我以前的一些嘗試……它似乎手動指定埠是實際的解決方案。

我之前一定是打錯了，或者如果 G Suite 中的外部配置可能導致上述錯誤，那麼設置的更改尚未傳播。

WEBLATE_EMAIL_HOST: "smtp-relay.gmail.com"

# THE SOLUTION #
WEBLATE_EMAIL_PORT: 587

WEBLATE_SERVER_EMAIL: "weblate@example.org"
WEBLATE_DEFAULT_FROM_EMAIL: "weblate@example.org"
WEBLATE_USE_SSL: 0
WEBLATE_USE_TLS: 1
