Docker设置与Python应用程序的Mysql容器

Question

我有一个运行"dockerfile/mysql"的容器,我可以连接并与之交互.我正在尝试为将从mysql数据库读取的Python应用程序构建另一个映像.问题是Python应用程序需要MySQL-python并尝试在安装时安装它.因为这个容器不能容纳mysql服务器,所以我最终得到了;

Downloading/unpacking MySQL-python
Downloading MySQL-python-1.2.5.zip (108kB): 108kB downloaded
Running setup.py (path:/tmp/pip_build_vagrant/MySQL-python/setup.py) egg_info for package MySQL-python
sh: 1: mysql_config: not found
Traceback (most recent call last):
  File "<string>", line 17, in <module>
  File "/tmp/pip_build_vagrant/MySQL-python/setup.py", line 17, in <module>
    metadata, options = get_config()
  File "setup_posix.py", line 43, in get_config
    libs = mysql_config("libs_r")
  File "setup_posix.py", line 25, in mysql_config
    raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
Complete output from command python setup.py egg_info:
sh: 1: mysql_config: not found

这是完全可以理解的.

我应该如何设置我的Python应用程序容器(使用SQLAlchemy)从mysql容器中读取？

谢谢

Answer 1

加入apt-get install -y libmysqlclient-dev你的Dockerfile.

Answer 2

如果您使用python:3.5-alpine,可以mysqlclient通过在以下代码中添加以下代码来安装Dockerfile:

RUN set -e; \
        apk add --no-cache --virtual .build-deps \
                gcc \
                libc-dev \
                linux-headers \
                mariadb-dev \
                python3-dev \
                postgresql-dev \
        ;

整体Dockerfile将是这样的:

# Version: 0.0.1
FROM python:3.5-alpine
ENV PYTHONUNBUFFERED 1
RUN set -e; \
        apk add --no-cache --virtual .build-deps \
                gcc \
                libc-dev \
                linux-headers \
                mariadb-dev \
                python3-dev \
                postgresql-dev \
        ;
RUN mkdir /djcode
WORKDIR /djcode
ENV REFRESHED_AT 2017-12-25
ADD requirements.txt /djcode/
RUN pip install --no-cache-dir -r /djcode/requirements.txt
RUN pip install uwsgi
ADD . /djcode/
EXPOSE 6001
