k8s-sample-management-system

k8s 资源对象的简易后台管理系统

项目思路与功能

功能：预计提供k8s资源的增删改查。

查询功能：

workload

1. pod
2. deployment
3. statefulset
4. job
5. cronjob

命名空间

1. namespace

服务发现

1. service
2. ingress

配置文件

1. configmap
2. secret

项目启动

1. 进入把目标集群的.kube/config文件放入项目根目录

➜  k8s-Management-System git:(main) ls -a | grep config
config

config文件示例(部分...)

apiVersion: v1
clusters:
- cluster:
    server: https://xxxxxxxxx:6443
  name: kubernetes
contexts:
.......

2. 加入远程node连接的配置文件app.yaml

• 根目录下加入app.yaml，内容如下，分别填入节点名、ip、用户与密码

k8s:
  nodes:
    - name: xxxxxxx
      ip: xxxxxxx
      user: xxxxx
      pass: xxxxxx
    - name: xxxxxxx
      ip: xxxxxxx
      user: xxxxxxx
      pass: xxxxxxx
    - name: xxxxxxx
      ip: xxxxxxx
      user: xxxxxxx
      pass: xxxxxxx

3. 启动server

➜  k8s-Management-System git:(main) ✗  go run main.go
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:   export GIN_MODE=release
 - using code:  gin.SetMode(gin.ReleaseMode)

4. 使用postman调用接口
   调用接口方法

查询列表接口
