gitlab-jenkins-shell-helm-chart-k8s自动化部署微服务-编程知识

1.准备好编译环境的容器，所有容器的镜像制作在gemdale-dockerfile这个代码库里面，也可以直接拉取官方镜像部署

docker run --name node1420-patternx -v /data/var/www/:/data/var/www/ -v /var/jenkins_home/:/var/jenkins_home/ -v /mnt/hgfs/:/mnt/hgfs/ --net host --restart always -d -t node:14.20.0docker run --name node1615-patternx  -v /data/var/www/:/data/var/www/ -v /var/jenkins_home/:/var/jenkins_home/ -v /mnt/hgfs/:/mnt/hgfs/ --net host --restart always -d -t node:16.15.1docker run --name nodejs1417-patternx -v /data/var/www/:/data/var/www/ -v /var/jenkins_home/:/var/jenkins_home/ -v /mnt/hgfs/:/mnt/hgfs/ --net host --restart always -d -t jelastic/nodejs:14.17.5-foreverFROM node:16.20.1-bullseye

2.发布jenkins的shell执行脚本代码在仓库gemdale_jenkins

gemdale_jenkins
在这里插入图片描述
This project is parameterized
Choice Parameter 参数的名称这些参数作为环境变量公开用于构建
这个是定义项目脚本里面的变量
dr 默认是deploy部署脚本可以选rollback回滚脚本

project ienjoys 项目变量

env test prod 环境变量
在这里插入图片描述
部署到服务器

实际部署的服务service是服务名称变量，gemdale_jenkins是实际服务名

代码分支

选择变量false，true：是否更新helm chart release. 默认为false, 即不更新.第一次执行要选true

回滚设置

在这里插入图片描述
