Dockerfile制作ubuntu:20.04镜像并配置python3.9的环境以及基于python镜像构建环境

Dockerfile 拉取ubuntu:20.04镜像并配置python3.9的环境

1.构建镜像
requirements.txt里是Python要安装的包，文件和Dockerfile放在同一个目录。
代码结构

2.一次性构建

FROM ubuntu:20.04 ENV DEBIAN_FRONTEND=noninteractive ENV LANG C.UTF-8 RUN sed -i 's@http://archive.ubuntu.com/ubuntu/@http://mirrors.aliyun.com/ubuntu/@g' /etc/apt/sources.list RUN apt-get update -qq RUN mkdir -p /gemdale WORKDIR /gemdale COPY TBQA/requirements.txt requirements.txt ADD TBQA /gemdale RUN cp /gemdale/app.py /gemdale/scripts RUN apt-get clean && \ apt-get update && \ apt-get install -y libmysqlclient-dev tzdata \ python3 python3-dev python3-pip libpcre3 libpcre3-dev uwsgi-plugin-python3\ && apt-get clean \ && apt-get autoclean \ && ln -sf /usr/bin/pip3 /usr/bin/pip && ln -sf /usr/bin/python3 /usr/bin/python \ && pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple RUN apt-get update -q \ && apt-get install -y wget curl vim CMD bash -c 'sh /gemdale/scripts/build.sh;sh /gemdale/scripts/run_sync.sh' 

3.分开构建，先做个基础镜像，这样不用每次全部构建,很耽误时间

FROM ubuntu:20.04 ENV DEBIAN_FRONTEND=noninteractive ENV LANG C.UTF-8 RUN sed -i 's@http://archive.ubuntu.com/ubuntu/@http://mirrors.aliyun.com/ubuntu/@g' /etc/apt/sources.list RUN apt-get update -qq COPY TBQA/requirements.txt requirements.txt RUN apt-get clean && \ apt-get update && \ apt-get install -y libmysqlclient-dev tzdata \ python3 python3-dev python3-pip libpcre3 libpcre3-dev uwsgi-plugin-python3\ && apt-get clean \ && apt-get autoclean \ && ln -sf /usr/bin/pip3 /usr/bin/pip && ln -sf /usr/bin/python3 /usr/bin/python \ && pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple RUN apt-get update -q \ && apt-get install -y wget curl vim 

4.流水线里面运用基础镜像增量构建

FROM gem-acr-p-a01-registry.cn-shenzhen.cr.aliyuncs.com/devops/ubuntu20-python3.9:v0.1 ENV DEBIAN_FRONTEND=noninteractive ENV LANG C.UTF-8   RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime RUN echo 'Asia/Shanghai' >/etc/timezone RUN mkdir -p /gemdale WORKDIR /gemdale COPY TBQA/requirements.txt requirements.txt ADD TBQA /gemdale RUN cp /gemdale/app.py /gemdale/scripts RUN pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple CMD bash -c 'sh /gemdale/scripts/build.sh;sh /gemdale/scripts/run_sync.sh' 

5.云效流水线发布


docker 镜像启动环境变量生效
将 source /etc/profile 命令写入 ~/.bashrc中

 vim ~/.bashrc RUN echo source /etc/profile >> ~/.bashrc 

这样自己制作比较麻烦，还有更简单的就是去到docker官网获取python3.9版本的基础镜像构建
Dockerfile

        FROM python:3.9.10-buster  ENV LANG=C.UTF-8  RUN ln -snf /usr/share/zoneinfo/PRC /etc/localtime  RUN mkdir /root/.pip/ COPY pip.conf /root/.pip/ RUN chmod 0644 /root/.pip/pip.conf  RUN pip3 install Flask==1.1.2 RUN pip3 install joblib==1.1.0 RUN pip3 install onnxruntime==1.10.0 RUN pip3 install psutil==5.8.0 RUN pip3 install requests==2.26.0 RUN pip3 install torch==1.10.1 RUN pip3 install transformers==4.15.0 RUN pip3 install scikit-learn==0.24.2 

pip.conf

[global] index-url = https://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com 

7.云效发布docker容器

部署脚本

#!/bin/bash if [[ `docker inspect -f '{{ .Name }}' ${appname}` == "/${appname}" ]]; then echo "停止${appname}" docker stop ${appname} && docker rm ${appname}; else echo "${appname}服务未启动" fi docker run -d --name=${appname} --restart=always --network=host -p ${hostport}:${containerport} -v /gemdale/logs:/gemdale/logs ${IMAGE} 

gem-acr-p-a01-registry.cn-shenzhen.cr.aliyuncs.com/osale/osale-prediction-service:prod-2023-03-31-17-43-27

这个是镜像地址由自己定义的osale（空间）osale-prediction-service（仓库）prod-2023-03-31-17-43-27（标签）构成，如果定义了，这些变量缺一不可
M A V E N P R O F I L E − {MAVEN_PROFILE}- MAVENP​ROFILE−{DATETIME}等于prod-2023-03-31-17-43-27

docker启动容器之后马上又自动关闭解决办法
问题描述：
centos 启动一个容器添加了-d 参数，但是docker ps 或者docker ps -a查看却已经退出了
退出原因
1、docker容器运行必须有一个前台进程， 如果没有前台进程执行，容器认为空闲，就会自行退出
2、容器运行的命令如果不是那些一直挂起的命令（ 运行top，tail、循环等），就是会自动退出
3、这个是 docker 的机制问题
解决代码
CMD bash -c ‘pm2 start ecosystem.config.js –env test;tail -f /dev/null’
