3.2 main.js

src/main.js中引入codemirror

//codemirror编辑器
import { GlobalCmComponent } from "codemirror-editor-vue3";
// 引入主题
import 'codemirror/theme/idea.css'
// 引入yaml
import 'codemirror/mode/yaml/yaml.js'

4. 测试

4.1 显示命名空间下的deployment

4.2 创建Deployment

命令行下确认

4.3 显示yaml

通过修改yaml给deployment增加标签

4.4 删除deployment

命令行下确认

4.5 扩缩容

4.5.1 扩容

命令行确认

4.5.2 缩容

命令行

4.6 重启
