【GO】k8s 管理系统项目23[前端部分–工作负载-Pod]

k8s 管理系统项目[前端部分–工作负载-Deployment]

1. 代码部分

1.1 准备工作

由于Pod页面和Deployment内容差不多.那么就直接把Deployment的内容复制过来.再做修改.

1. 替换Deployment为Pod
2. 替换Deploy为Pod
3. 替换deployment为pod
4. 替换deploy为pod
5. 禁用新增的按钮,删除新增方法,表单
6. 删除扩容和重启的按钮,方法,抽屉

1.2 Pod前端代码

src/views/workload/Pod.vue

2. 功能测试

2.1 获取pod清单和分页

2.2 获取pod详细信息

2.2.1 pod详情

2.2.2 Pod环境变量

2.2.2 Pod日志

2.2.4 控制台

2.3 Yaml

2.4 删除Pod

3. 两个小bug

3.1 router错误

之前写后端路由时/api/k8s/pod/detail写成了/api/k8s/pods/detail

造成获取yaml时无法获得消息.

尝试用api调用发现问题,修改了router下的路由问题解决

3.2 翻页的问题

之前后端GetPods中取total写成了

	filtered := selectableData.Filter()// 排序和分页data := filtered.Sort().Paginate()total := len(data.GenericDataList)

改了下问题解决

	filtered := selectableData.Filter()total := len(filtered.GenericDataList)// 排序和分页data := filtered.Sort().Paginate()
