docker打包flask项目镜像

1. 本地新建一个目录config，该目录下新建一个sources.list文件 ，目的是使用国内镜像源安装

sources.list具体内容如下：

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse

2.拷贝项目到config目录下：

3. config目录下新建dockerfile文件

dockerfile具体内容如下：

# 指定所创建镜像的基础镜像
FROM ubuntu
LABEL author="xxx"
#用ubuntu国内源替换默认源
RUN rm /etc/apt/sources.list
COPY sources.list /etc/apt/sources.list

WORKDIR /app
ADD . /app

#安装python
RUN apt-get update
RUN apt-get install -y python python-pip
RUN pip install --upgrade pip

# 安装依赖
RUN pip install -r requirements.txt
# 声明镜像内服务监听的端口
EXPOSE 80

CMD ["python", "app.py"]

4. 创建名称为hello的镜像，. 表示dockerfile文件所在目录

docker build -t hello .

5. 启动镜像

docker run -itd -p 4000:80 hello  # 守护模式启动镜像

6.python操作脚本启动

test.sh脚本文件

#! /bin/bash

docker run -itd -p 4000:80 test  # test为容器名

python代码

import subprocess

status, res = subprocess.getstatusoutput('/bin/bash /Users/Desktop/shell/test.sh')  # status为0表示执行成功

print(status)
