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。

- 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;
