大佬教程收集整理的这篇文章主要介绍了无法为Django和Mysql触发Docker构建，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
在apt-get安装后只运行pip安装要求，因为MysqLclIEnt需要libMysqLclIEnt-dev：
您正在将apt软件包管理器与不兼容的alpine基本linux映像一起使用。我建议将python3.7-slim与支持apt的debian os一起使用。
FROM python:3.7-slim
MAINTAINER Intersources Inc.
ENV PYTHONUNBUFFERED 1
RUN apt-get update
RUN apt-get install python3-dev default-libMysqLclIEnt-dev gcc -y
copY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt
RUN mkdir /app
workdir /app
copY ./app /app
RUN adduser -D jeet
USER jeet
如果您确实需要像这样高山修改Dockerfile：
FROM python:3.7-alpine
MAINTAINER Intersources Inc.
RUN apk update
RUN apk add musl-dev mariadb-dev gcc
RUN pip install MysqLclIEnt
RUN mkdir /app
workdir /app
copY ./app /app
RUN adduser -D jeet
USER jeet
我正在用Djnago和MySql构建应用程序。我想使用docker来部署我的应用程序。我已经准备了一个requirement.txt，docker-
compose.yml和Dockerfile
docker-compose.yml
version: "3"
services:
law-application:
restart: always
build:
context: .
ports:
- "8000:8000"
volumes:
- ./app:/app
command: >
sh -c "python manage.py runserver 0.0.0.0:8000"
depends_on:
- mysql_db
mysql_db:
image: mysql:latest
command: mysqld --default-authentication-plugin=mysql_native_password
volumes:
- "./mysql:/var/lib/mysql"
ports:
- "3306:3306"
restart: always
environment:
- MYSQL_ROOT_PASSWORD=root
- MYSQL_DATABASE=root
- MYSQL_USER=root
- MYSQL_PASSWORD=root
requirements.txt
django>=2.1.3,<2.2.0
djangorestframework==3.11.0
mysqlclient==1.4.6
Docker文件
FROM python:3.7-alpine
MAINTAINER Intersources Inc.
ENV PYTHONUNBUFFERED 1
COPY ./requirements.txt /requirements.txt
RUN pip install -r /requirements.txt
RUN apt-get update
RUN apt-get install python3-dev default-libmysqlclient-dev -y
RUN mkdir /app
WORKDIR /app
COPY ./app /app
RUN adduser -D jeet
USER jeet
settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql','NAME': 'my-app-db','USER': 'root','PASSWORD': 'root','HOST': 'mysql_db','PORT': 3307,}
}
我一直在尝试运行命令docker build
.从docker文件构建映像，但出现此错误。看起来MySql连接器有问题。我尝试搜索解决方案，但找不到任何解决方法。如果从中删除 mysql_db
服务，则可以构建映像docker-compose.yml。
