Docker 構建：為 mariadb 運行 setup.py install 失敗

Question

我正在為必須與遠程 MariaDB 服務器連接的python 代碼構建一個docker 映像。 經過一些試驗和錯誤后，我能夠在本地運行它，但是為了使遠程（虛擬）服務器上的安裝更容易，我真的希望該解決方案也能與 docker 映像一起使用。

一旦我使用較舊的 alpine 版本 < 3.11，使用較低版本會導致兼容性問題：

MariaDB Connector/Python requires MariaDB Connector/C >= 3.1.5, found version 3.0.10

不同的 python 版本似乎也不起作用。

我的Dockerfile ：

FROM python:3.6-alpine
RUN apk add --no-cache mariadb-dev build-base
RUN pip install mariadb

控制台輸出：

> docker build . -t dockerpython

Answer 1

在安裝 mariadb 之前，您需要安裝一些依賴項。

MariaDB 版本 10.2 -- sudo apt-get install -y libmariadb-dev

MariaDB 版本 10.3 -- sudo apt-get install -y libmariadb-dev-compat

而不是使用 alpine 或 python 基礎圖像，您可以使用debian:slim基礎圖像。

Answer 2

我在MariaDB 的票務系統中提交了（並且已經修復了）這個錯誤

該修復程序將在 MariaDB Connector/Python 1.0.4 中提供（可能會在本周末通過 pypi.org 提供）。

作為一種解決方法，您可以從github 存儲庫下載最新版本並手動構建它，或者您可以嘗試（我沒有測試過）

export CFLAGS=-D_GNU_SOURCE=1
pip3 install mariadb
