+# 一键还原项目
+一键还原 CI 中的项目
+
+### 1. 项目组dsl文件
+**语法**
+```
+groups:
+  - name: xxx
+    projects:
+      - xxx
+      - xxx
+  - name: xxx
+    projects:
+      - xxx
+      - xxx
+```
+* name: 项目组的名称，尚未设置时为默认分组
+* projects: 需要导入的项目dsl文件，git仓库根目录的相对路径
+
+**示例**
+```
+groups:
+  - name: 
+    projects:
+      # 批量导入
+      - /batch_import.yml
+      # 建木api网关
+      - /api-gw/cicd.yml
+      # 建木ci
+      - /ci/server_cicd.yml
+      - /ci/ui_cicd.yml
+      # 开发工具
+      - /dev-tools/docker_image_builder.yml
+      # 建木hub
+      - /hub/server_cicd.yml
+      - /hub/ui_cicd.yml
+      # 官网
+      - /official-site/cicd.yml
+      # ssl证书
+      - /ssl/cert_cd.yml
+```
+
+### 2. 使用
+1.通过 [git clone](https://hub.jianmu.run/_/git_clone) 节点拉取项目组dsl文件、项目dsl文件所在的git仓库
+
+2.通过 [同步项目组](https://hub.jianmu.run/_/sync_project_group) 节点，同步项目组dsl文件中定义的项目
+
+**管道示例**
+```
+pipeline:
+  name: 批量导入项目
+  git_clone:
+    type: git_clone:1.1.1
+    param:
+      remote_url: https://gitee.com/jianmu-dev/jianmu-ci-dsl.git
+      ref: refs/heads/master
+      netrc_machine: gitee.com
+      netrc_username: ((gitee.username))
+      netrc_password: ((gitee.password))
+  sync_project_group:
+    type: sync_project_group:1.0.0
+    param:
+      ci_url: https://ci.jianmu.run
+      ci_username: ((xxx.xxx))
+      ci_password: ((xxx.xxx))
+      git_path: ${git_clone.git_path}
+      group_file_path: /project_group.yml
+      deletable: false
+```
