使用jenkins构建项目并启动docker容器

A一.基础环境搭建

1.docker私服搭建

参考 文档

// 用docker建立私有仓库
docker run -d -v /opt/module/docker-registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry

// 查看本机已有镜像
docker image ls

// 标记并上传
docker tag xxx:v 127.0.0.1:5000/xxx:v
docker push 127.0.0.1:5000/xxx:v

// 查询仓库里的镜像
curl 127.0.0.1:5000/v2/_catalog

// 删除本地镜像
docker image rm 127.0.0.1:5000/xxx:v

// 拉取仓库镜像到本地
docker pull 127.0.0.1:5000/xxx:v

二.构建

git配置参考​​​

// 按根目录下Dockerfile文件打镜像
docker build -t 172.16.184.126:5000/ci-test .

// 推到docker私服
docker push 172.16.184.126:5000/ci-test

基础镜像选择

python:3.8-slim-buster

python:3.8-slim

python:3.8-alpine
