DevOps .net core Jenkins持续集成Linux、Docker、K8S

jenkins插件

系统管理 -> 管理插件,安装如下插件。

#如果搜索不到去掉Plugin在搜索
GitLab Plugin
Gitlab Hook Plugin
#使用Gitlab账号做用户权限管理,可选(也可集成LDAP)
Gitlab Authentication plugin

Docker plugin
docker-build-step

SSH plugin

GitLab Plugin配置

在GitLab中配置,创建个人访问令牌后获取到令牌备用

系统管理 -> 系统设置 中 左上角 'Jenkins > 配置' 选择GitLab

  • Connection Name随便填;
  • Git Host URL填GitLab的域名地址,例如http://gitlab.yourdomain.com/;
  • Credentials配置;

Credentials配置

  • 类型选择GitLab API token
  • 将令牌填充到API token中
  • 描述 名称

创建构建任务

  • 新建任务 -> 输入名称 选择构建一个自由风格的软件项目;完成后进入配置。

  • 源码管理 -> Git;

Repository URL:中填入gitlab项目对应的ssh路径(eg:git@git.cn:group/sample.app.git);

Credentials:设置添加SSH私钥;

同时在gitlab(http://xxx/profile/keys)添加ssh公钥

  • 构建触发器 -> 勾选Build when a change is pushed to GitLab;

将GitLab webhook URL: http://xxx/group/sample.app、Secret token添加到gitlab(http://xxx/group/sample.app/settings/integrations)


  • 构建环境 -> 勾选Delete workspace before build starts、Add timestamps to the Console Output;

  • 构建 -> 增加构建步骤 -> 执行 shell;

添加sh脚本,jenkins服务需要安装dotnet。
如果需要.netcore多版本环境参考CentOS 7 下安装部署.NET Core多版本环境

#!/bin/sh

pwd
ls

whoami
which dotnet
dotnet --info
dotnet --version

  • 构建 -> 增加构建步骤 -> Build / Publish Docker Image;

在上面直接使用shell命令,未使用此功能

  • 构建 -> 增加构建步骤 -> Execute shell script on remote host using ssh;

部署

#Command中shell脚本
echo '=====虚拟机方式====='
supervisorctl restart youserver-name

echo '=====Docker swarm 方式====='
docker -v
docker stack deploy -c test.yml --with-registry-auth test

echo '=====K8s 方式====='
cd /usr/local/src
kubectl apply -f .
kubectl get pod

虚拟机方式

Docker swarm方式

K8s 方式
