问题描述
执行'docker build -t $ name'。在以下问题上失败。它显示“找不到mariadb_config”，但我已经在此suse15 linux服务器上安装了mariadb。

Either set the environment variable MARIADB_CONfig or edit the configuration

The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1
和相关的Dockerfile内容如下。
FROM python:3.6.5
workdir /slic-scripts
copY requirements.txt .
RUN pip install --upgrade pip
RUN pip3 install -r requirements.txt
copY . .
CMD ["python3","/slic-scripts/run_cmd.sh"]
解决方法
在运行pip3 install之前，您需要在Dockerfile中安装MariaDB Connector / C。将其安装在主机上并没有帮助。
就像@Jonathan Jacobson所写的那样，您需要在Docker映像中安装MariaDB连接器，然后再继续进行pip install。
由于python:3.6.5基于debian Stretch，因此那里提供的连接器是2.3.2，mariadb模块不支持（如prerequisites中所述）。要解决此问题，您可能需要切换到其他图片（例如3.6克星）。
这是一个工作测试：
FROM python:3.6-buster
RUN apt-get update \
&& apt-get -yy install libmariadb-dev
WORKDIR /slic-scripts
COPY requirements.txt .
RUN pip install --upgrade pip
RUN pip3 install -r requirements.txt
COPY . .
CMD ["python3","/slic-scripts/run_cmd.sh"]
使用以下命令安装MariaDB Connector / C，这是一个依赖项。
sudo apt-get install libmariadb3 libmariadb-dev
RUN pip3 install -r requirements.txt
