1.Python镜像

1.1Dokcerfile

FROM python:3.6
# 创建目录
RUN mkdir /usr/src/app
# 将当前目录下的文件全部复制过去，只有是复制项目，uwsgi配置文件
COPY . /usr/src/app/
# 设置工作目录
WORKDIR /usr/src/app

# 更新pip
RUN pip install --upgrade pip
RUN pip install -i https://pypi.doubanio.com/simple/  -r /usr/src/app/config/requirements.txt

# 在run的时候启动uwsgi
# CMD uwsgi --ini uwsgi_conf.ini
# 暴露端口
EXPOSE 8000

1.2制作镜像并生成容器

制作镜像

docker image build -t djangoproject:1.0 .

简单生成容器，这里先用run指令来运行，后面再出一篇docker-compose的。

docker run -itd --name djangoproject -p 3210:8000 djangoproject:1.0

1.3效果

2.ubuntu镜像

ubuntu镜像（500+M）比Python（1G）镜像占内存更小。

2.1Dockerfile

# 基于 ubuntu:20.04
FROM ubuntu:20.04

#复制该文件夹至镜像
RUN mkdir /APP
ADD . /APP
# 设置工作目录
WORKDIR /APP

# 更新软件源为阿里云
RUN cat /APP/config/sources.list > /etc/apt/sources.list \
# 更新软件
 && apt-get -y update \
# 安装依赖
 && apt-get install -y python3-dev python3-pip \
 && apt-get install -y python3-setuptools \
 && apt-get install -y libmysqlclient-dev \
# 安装python依赖
 && pip config set global.index-url https://pypi.douban.com/simple/ \
 && pip install -r /APP/config/requirements.txt

#对外暴露端口
EXPOSE 8000
