简介
本章节主要讲解通过client-go、beego实现deployment列表、创建deployment、读取yaml配置、重启deployment这四个功能，再结合layui、layuimini模板实现也没展，功能只要是由控制器、模型、路由、前端代码几部分组成，现将各个模块的功能进行分布讲解。
一.读取k8s的deployment列表功能
1.1.controllers控制器代码
控制部分代码通过传递集群ID、命名空间、deploy名称、标签来调用控制器中的DeployList函数来进行过滤查询。
func (this *DeployController) List() {
clusterId := this.GetString("clusterId")
nameSpace := this.GetString("nameSpace")
deployName := this.GetString("deployName")
labels := this.GetString("labels")
labelsKV := strings.Split(labels, ":")
var labelsKey, labelsValue string
if len(labelsKV) == 2 {
labelsKey = labelsKV[0]
labelsValue = labelsKV[1]
}
depList, err := m.DeployList(clusterId, nameSpace, deployName, labelsKey, labelsValue) //查询列表函数
msg := "success"
code := 0
count := len(depList)
if err != nil {
msg = err.Error()
code = -1
}
this.Data["json"] = &map[string]interface{}{"code": code, "msg": msg, "count": count, "data": &depList}
this.ServeJSON()
}
1.2.models模型代码
该模块功只要是先定义一个需要列表中显示的信息的结构体，然后通过DeploymentClient.List获取deploy的所有资源deplist.Items，然后通过循环对返回的数据进行整理，提取结构体中的信息，然后定义个结构体数组var bbb = make([]Deploy, 0)，并将信息不断追加到结构体数组中
//定义一个deploy信息的结构体
type Deploy struct {
DeployName string `json:"deployName" form:"deployName"` //名称
NameSpace string `json:"nameSpace" form:"nameSpace"` //命名空间
RevisionHistoryLimit int32 `json:"revisionHistoryLimit" form:"historyVersionLimit"` //保留的历史版本
Replicas int32 `json:"replicas" form:"replicas"` //副本数
AvailableReplicas int32 `json:"availableReplicas"` //可用副本数
PodNumber string `json:"podNumber"` //pod数量
Labels string `json:"labels" form:"labels"` //标签
ContainerName string `form:"containerName"` //container的名称
ImageUrl string `json:"imageUrl" form:"imageUrl"` //镜像地址
ContainerPortName string `json:"-"form:"containerPortName"` //container端口名称
ContainerPort string `form:"containerPort"` //端口
HostPort int32 `form:"hostPort"` //主机端口
CreateTime string `json:"createTime"` //创建时间
}
func DeployList(kubeconfig, namespace, deployName string, labelsKey, labelsValue string) ([]Deploy, error) {
//通过kubeconfig集群认证文件生成一个客户端操作对象clientset
clientset := common.ClientSet(kubeconfig)
//创建一个deployment资源的接口对象DeploymentClient，用于操作指定名称空间的deployment资源
if namespace == "" {
//namespace = corev1.NamespaceDefault
namespace = corev1.NamespaceAll
}
DeploymentClient := clientset.AppsV1().Deployments(namespace)
//设置ListOptions
var listOptions = metav1.ListOptions{}
if labelsKey != "" && labelsValue != "" {
listOptions = metav1.ListOptions{
LabelSelector: fmt.Sprintf("%s=%s", labelsKey, labelsValue),
}
}
deplist, err := DeploymentClient.List(context.TODO(), listOptions)
var bbb = make([]Deploy, 0)
for _, dep := range deplist.Items {
//搜索
if deployName != "" {
if !strings.Contains(dep.Name, deployName) {
continue
}
}
//用于判断是否有appanme标签，并根据标签记录对应的资源到应用下
var labelsStr, imgUrlStr, containerNameStr, ContainerPortNameStr, ContainerPortStr string
for kk, vv := range dep.ObjectMeta.Labels {
labelsStr += fmt.Sprintf("%s:%s,", kk, vv)
}
if len(labelsStr) > 0 {
labelsStr = labelsStr[0 : len(labelsStr)-1]
}
for _, v2 := range dep.Spec.Template.Spec.Containers {
containerNameStr += fmt.Sprintf("%s,", v2.Name)
imgUrlStr += fmt.Sprintf("%s,", v2.Image)
if len(v2.Ports) > 0 {
ContainerPortNameStr += fmt.Sprintf("%s,", v2.Ports[0].Name)
ContainerPortStr += fmt.Sprintf("%d,", v2.Ports[0].ContainerPort)
}
}
if len(containerNameStr) > 0 {
containerNameStr = containerNameStr[0 : len(containerNameStr)-1]
}
if len(imgUrlStr) > 0 {
imgUrlStr = imgUrlStr[0 : len(imgUrlStr)-1]
}
if len(ContainerPortNameStr) > 0 {
ContainerPortNameStr = ContainerPortNameStr[0 : len(ContainerPortNameStr)-1]
}
if len(ContainerPortStr) > 0 {
ContainerPortStr = ContainerPortStr[0 : len(ContainerPortStr)-1]
}
depItems := &Deploy{
DeployName: dep.Name,
NameSpace: dep.Namespace,
RevisionHistoryLimit: *dep.Spec.RevisionHistoryLimit,
Replicas: *dep.Spec.Replicas,
AvailableReplicas: dep.Status.AvailableReplicas,
PodNumber: fmt.Sprintf("%d/%d", dep.Status.AvailableReplicas, *dep.Spec.Replicas),
Labels: labelsStr,
ContainerName: containerNameStr,
ImageUrl: imgUrlStr,
ContainerPortName: ContainerPortNameStr,
ContainerPort: ContainerPortStr,
CreateTime: dep.CreationTimestamp.Format("2006-01-02 15:04:05"),
}
bbb = append(bbb, *depItems) //将读取的deploy信息循环追加到结构体数组中
}
return bbb, err
}
二.创建deployment功能
2.1.创建deploy控制器代码
2.1该功能主要是通过在页面的表单输入名称、镜像、副本数、端口、标签等信息，然后创建一个deploy,控制器部分代码，直接将获取body内容this.Ctx.Input.RequestBody传递到DeployCreate函数去处理
func (this *DeployController) Create() {
clusterId := this.GetString("clusterId")
code := 0
msg := "success"
err := m.DeployCreate(clusterId, this.Ctx.Input.RequestBody)
if err != nil {
code = -1
msg = err.Error()
log.Printf("[ERROR] Deploy Create Fail:%s\n", err)
}
this.Data["json"] = &map[string]interface{}{"code": code, "msg": msg}
this.ServeJSON()
}
2.2 models模型代码
2.2.通过前端传递的body用gjson进行解析，提取表单数据，然后定义一个结构体appsv1.Deployment，并将表单中的数据对应上，然后调用DeployClient.Create进行创建。
func DeployCreate(kubeconfig string, bodys []byte) error {
gp := gjson.ParseBytes(bodys)
clusterId := gp.Get("clusterId").String()
if kubeconfig == "" {
kubeconfig = clusterId
}
deployName := gp.Get("deployName").String()
nameSpace := gp.Get("nameSpace").String()
containerPort := gp.Get("containerPort").Int()
replicas := gp.Get("replicas").Int()
var pullPolicy corev1.PullPolicy
imagePullPolicy := gp.Get("imagePullPolicy").String()
switch imagePullPolicy {
case "Never":
pullPolicy = corev1.PullNever
case "IfNotPresent":
pullPolicy = corev1.PullIfNotPresent
default:
pullPolicy = corev1.PullAlways
}
imageUrl := gp.Get("imageUrl").String()
//var labelsMap = make(map[string]string)
labelsMap := map[string]string{
"app": deployName,
}
for _, vv := range gp.Get("lables").Array() {
labelsMap[vv.Get("key").String()] = vv.Get("value").String()
}
deployInstance := &appsv1.Deployment{
TypeMeta: metav1.TypeMeta{
Kind: "Deployment",
APIVersion: "apps/v1",
},
ObjectMeta: metav1.ObjectMeta{
Name: deployName,
Namespace: nameSpace,
Labels: labelsMap,
},
Spec: appsv1.DeploymentSpec{
Replicas: int32Ptr(int32(replicas)),
Selector: &metav1.LabelSelector{
MatchLabels: labelsMap,
},
RevisionHistoryLimit: int32Ptr(10),
Template: corev1.PodTemplateSpec{
ObjectMeta: metav1.ObjectMeta{
//Name: "golang-pod",
Labels: labelsMap,
},
Spec: corev1.PodSpec{
Containers: []corev1.Container{
corev1.Container{
Name: deployName,
Image: imageUrl,
ImagePullPolicy: pullPolicy,
Ports: []corev1.ContainerPort{
corev1.ContainerPort{
//Name: "" ,
ContainerPort: int32(containerPort),
//HostPort: deployment.HostPort,
Protocol: corev1.ProtocolTCP,
},
},
},
},
},
},
},
}
DeployClient := common.ClientSet(kubeconfig).AppsV1().Deployments(nameSpace)
//调用DeployClient接口中的create方法，创建deployment资源
_, err := DeployClient.Create(context.TODO(), deployInstance, metav1.CreateOptions{})
if err != nil {
return err
}
return nil
}
三.读取deployment的yaml配置功能
3.1.controllers控制器代码
3.1.通过传递集群ID、命名空间、deploy名称读取yaml配置
func (this *DeployController) Yaml() {
clusterId := this.GetString("clusterId")
namespace := this.GetString("nameSpace")
deployName := this.GetString("deployName")
yamlStr, _ := m.GetDeployYaml(clusterId, namespace, deployName)
this.Ctx.WriteString(yamlStr)
}
3.2.models模型代码
3.2.查询具体的deploy名称，然后将deploy的配置信息进行非结构化转换，并解析成yaml配置返回
func GetDeployYaml(kubeconfig, namespace, deploy string) (string, error) {
DeploymentClient := common.ClientSet(kubeconfig).AppsV1().Deployments(namespace)
deployment, err := DeploymentClient.Get(context.TODO(), deploy, metav1.GetOptions{})
deploymentUnstructured, err := runtime.DefaultUnstructuredConverter.ToUnstructured(deployment)
if err != nil {
return "", err
}
yamlBytes, err := yaml.Marshal(deploymentUnstructured)
if err != nil {
return "", err
}
return string(yamlBytes), nil
}
四.重启deployment
4.1.重启deploy的控制器代码
4.1.通过传递的deploy名称并调用DeployRestart函数进行重启
func (this *DeployController) Restart() {
clusterId := this.GetString("clusterId")
namespace := this.GetString("nameSpace")
deployName := this.GetString("deployName")
code := 0
msg := "success"
err := m.DeployRestart(clusterId, namespace, deployName)
if err != nil {
log.Println(err)
code = -1
msg = err.Error()
}
this.Data["json"] = &map[string]interface{}{"code": code, "msg": msg}
this.ServeJSON()
}
4.2.重启deploy的模型代码
4.2.通过传递过来的deploy名称，然后patch一个申明去触发容器进行滚动更新
func DeployRestart(kubeconfig, namespace, deployName string) error {
patchOpt := metav1.PatchOptions{FieldManager: "kubectl-rollout"}
patchInfo := fmt.Sprintf(`{"spec":{"template":{"metadata":{"annotations":{"kubectl.kubernetes.io/restartedAt":"%s"}}}}}`, time.Now().Format(time.RFC3339))
_, err := common.ClientSet(kubeconfig).AppsV1().Deployments(namespace).Patch(context.TODO(), deployName, types.StrategicMergePatchType, []byte(patchInfo), patchOpt)
return err
}
五.路由配置
url路由配置，在routers/route.go中增加如下路径
beego.Router("/deploy/v1/List", &controllers.DeployController{}, "*:List") //列表
beego.Router("/deploy/v1/Restart", &controllers.DeployController{}, "*:Restart") //重启
beego.Router("/deploy/v1/Yaml", &controllers.DeployController{}, "*:Yaml") //读取yaml配置
beego.Router("/deploy/v1/Create", &controllers.DeployController{}, "*:Create") //创建
六.前端部分代码
6.1.前端列表展示的html代码
放在front/page/xkube/deployList.html,加载数据到表格的函数主要是javascript中table.render,然后渲染到currentTableId这个id表格,currentTableId的位置在body内的table这里

6.3.读取yaml配置的html
6.3.frot/page/xkube/deployYaml.html,配置的显示是通过monaco-editor来进行显示，网上下载一个monaco-editor:https://github.com/Microsoft/monaco-editor,国内的镜像地址： https://gitee.com/mirrors/monaco-editor 放到front目录下，
