這篇文章主要為大家介紹了Go語(yǔ)言開(kāi)發(fā)k8s之Deployment操作解析，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

1. 結(jié)構(gòu)體

1.1 DeploymentList

所屬包："k8s.io/api/apps/v1"

type DeploymentList struct {
    v1.TypeMeta `json:",inline"`
    v1.ListMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`
    Items           []Deployment `json:"items" protobuf:"bytes,2,rep,name=items"`
}

其中Items的每個(gè)成員的結(jié)構(gòu)體Deployment 如下：

1.2 Deployment

所屬包："k8s.io/api/apps/v1"

type Deployment struct {
    v1.TypeMeta   `json:",inline"`
    v1.ObjectMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`
    Spec              DeploymentSpec   `json:"spec,omitempty" protobuf:"bytes,2,opt,name=spec"`
    Status            DeploymentStatus `json:"status,omitempty" protobuf:"bytes,3,opt,name=status"`
}

其中各成員結(jié)構(gòu)體如下：

1.3 TypeMeta

所屬包 "k8s.io/apimachinery/pkg/apis/meta/v1"

type TypeMeta struct {
    Kind       string `json:"kind,omitempty" protobuf:"bytes,1,opt,name=kind"`
    APIVersion string `json:"apiVersion,omitempty" protobuf:"bytes,2,opt,name=apiVersion"`
}

對(duì)應(yīng)k8s的yml文件

apiVersion: apps/v1
kind: Deployment

1.4 ObjectMeta（metadata）

所屬包： "k8s.io/apimachinery/pkg/apis/meta/v1"

type ObjectMeta struct {
    Name                       string               `json:"name,omitempty" protobuf:"bytes,1,opt,name=name"`
    GenerateName               string               `json:"generateName,omitempty" protobuf:"bytes,2,opt,name=generateName"`
    Namespace                  string               `json:"namespace,omitempty" protobuf:"bytes,3,opt,name=namespace"`
    SelfLink                   string               `json:"selfLink,omitempty" protobuf:"bytes,4,opt,name=selfLink"`
    UID                        types.UID            `json:"uid,omitempty" protobuf:"bytes,5,opt,name=uid,casttype=k8s.io/kubernetes/pkg/types.UID"`
    ResourceVersion            string               `json:"resourceVersion,omitempty" protobuf:"bytes,6,opt,name=resourceVersion"`
    Generation                 int64                `json:"generation,omitempty" protobuf:"varint,7,opt,name=generation"`
    CreationTimestamp          Time                 `json:"creationTimestamp,omitempty" protobuf:"bytes,8,opt,name=creationTimestamp"`
    DeletionTimestamp          *Time                `json:"deletionTimestamp,omitempty" protobuf:"bytes,9,opt,name=deletionTimestamp"`
    DeletionGracePeriodSeconds *int64               `json:"deletionGracePeriodSeconds,omitempty" protobuf:"varint,10,opt,name=deletionGracePeriodSeconds"`
    Labels                     map[string]string    `json:"labels,omitempty" protobuf:"bytes,11,rep,name=labels"`
    Annotations                map[string]string    `json:"annotations,omitempty" protobuf:"bytes,12,rep,name=annotations"`
    OwnerReferences            []OwnerReference     `json:"ownerReferences,omitempty" patchStrategy:"merge" patchMergeKey:"uid" protobuf:"bytes,13,rep,name=ownerReferences"`
    Finalizers                 []string             `json:"finalizers,omitempty" patchStrategy:"merge" protobuf:"bytes,14,rep,name=finalizers"`
    ManagedFields              []ManagedFieldsEntry `json:"managedFields,omitempty" protobuf:"bytes,17,rep,name=managedFields"`
}

對(duì)應(yīng)k8s的yml文件中如下部分

metadata:
  ……

和k8s用yml文件創(chuàng)建deployment一樣，此處我們主要關(guān)心Name和Namespace

1.5 DeploymentSpec（spec）

屬于包："k8s.io/api/apps/v1"

type DeploymentSpec struct {
    Replicas                *int32                `json:"replicas,omitempty" protobuf:"varint,1,opt,name=replicas"`
    Selector                *v1.LabelSelector `json:"selector" protobuf:"bytes,2,opt,name=selector"`
    Template                v1.PodTemplateSpec    `json:"template" protobuf:"bytes,3,opt,name=template"`
    Strategy                DeploymentStrategy    `json:"strategy,omitempty" patchStrategy:"retainKeys" protobuf:"bytes,4,opt,name=strategy"`
    MinReadySeconds         int32                 `json:"minReadySeconds,omitempty" protobuf:"varint,5,opt,name=minReadySeconds"`
    RevisionHistoryLimit    *int32                `json:"revisionHistoryLimit,omitempty" protobuf:"varint,6,opt,name=revisionHistoryLimit"`
    Paused                  bool                  `json:"paused,omitempty" protobuf:"varint,7,opt,name=paused"`
    ProgressDeadlineSeconds *int32                `json:"progressDeadlineSeconds,omitempty" protobuf:"varint,9,opt,name=progressDeadlineSeconds"`
}

對(duì)應(yīng)k8s的yml文件中如下部分

spec:
  ……

和k8s用yml文件創(chuàng)建deployment一樣，這一部分是我們主要要傳入的信息。

1） Replicas（spec.replicas）

一個(gè) int的指針，因此賦值的時(shí)候我們只好先定義int變量，在把指針賦給它

2）LabelSelector（spec.selector）

所屬包："k8s.io/apimachinery/pkg/apis/meta/v1"

type LabelSelector struct {
    MatchLabels      map[string]string          `json:"matchLabels,omitempty" protobuf:"bytes,1,rep,name=matchLabels"`
    MatchExpressions []LabelSelectorRequirement `json:"matchExpressions,omitempty" protobuf:"bytes,2,rep,name=matchExpressions"`
}

和k8s用yml文件創(chuàng)建deployment一樣，我們主要用其中matchLabels打標(biāo)簽：

spec:
  selector:
    matchLabels:
      app: nginx

代碼種示例如下

            Selector: &amp;metaV1.LabelSelector{
                MatchLabels: map[string]string{
                    "app": "nginx",
                },
            },

3）PodTemplateSpec（spec.template）

所在包："k8s.io/api/core/v1"

type PodTemplateSpec struct {
    v1.ObjectMeta `json:"metadata,omitempty" protobuf:"bytes,1,opt,name=metadata"`
    Spec              PodSpec `json:"spec,omitempty" protobuf:"bytes,2,opt,name=spec"`
}

對(duì)應(yīng)k8s的yml文件中如下部分，顧名思義，這一部分定義的是pod的模板。

spec:
  ……
  template:
    ……

4）ObjectMeta （spec.template.metadata）

所在包："k8s.io/apimachinery/pkg/apis/meta/v1"

type ObjectMeta struct {
    Name                       string               `json:"name,omitempty" protobuf:"bytes,1,opt,name=name"`
    GenerateName               string               `json:"generateName,omitempty" protobuf:"bytes,2,opt,name=generateName"`
    Namespace                  string               `json:"namespace,omitempty" protobuf:"bytes,3,opt,name=namespace"`
    SelfLink                   string               `json:"selfLink,omitempty" protobuf:"bytes,4,opt,name=selfLink"`
    UID                        types.UID            `json:"uid,omitempty" protobuf:"bytes,5,opt,name=uid,casttype=k8s.io/kubernetes/pkg/types.UID"`
    ResourceVersion            string               `json:"resourceVersion,omitempty" protobuf:"bytes,6,opt,name=resourceVersion"`
    Generation                 int64                `json:"generation,omitempty" protobuf:"varint,7,opt,name=generation"`
    CreationTimestamp          Time                 `json:"creationTimestamp,omitempty" protobuf:"bytes,8,opt,name=creationTimestamp"`
    DeletionTimestamp          *Time                `json:"deletionTimestamp,omitempty" protobuf:"bytes,9,opt,name=deletionTimestamp"`
    DeletionGracePeriodSeconds *int64               `json:"deletionGracePeriodSeconds,omitempty" protobuf:"varint,10,opt,name=deletionGracePeriodSeconds"`
    Labels                     map[string]string    `json:"labels,omitempty" protobuf:"bytes,11,rep,name=labels"`
    Annotations                map[string]string    `json:"annotations,omitempty" protobuf:"bytes,12,rep,name=annotations"`
    OwnerReferences            []OwnerReference     `json:"ownerReferences,omitempty" patchStrategy:"merge" patchMergeKey:"uid" protobuf:"bytes,13,rep,name=ownerReferences"`
    Finalizers                 []string             `json:"finalizers,omitempty" patchStrategy:"merge" protobuf:"bytes,14,rep,name=finalizers"`
    ManagedFields              []ManagedFieldsEntry `json:"managedFields,omitempty" protobuf:"bytes,17,rep,name=managedFields"`
}

對(duì)應(yīng)k8s的yml文件中如下部分

spec:
  ……
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: nginx

代碼中示例如下

                ObjectMeta: metaV1.ObjectMeta{
                    Labels: map[string]string{
                        "app": deploymentName,
                    },
                }

    Containers                    []Container                `json:"containers" patchStrategy:"merge" patchMergeKey:"name" protobuf:"bytes,2,rep,name=containers"`

對(duì)應(yīng)k8s的yml文件中如下部分，是deployment中pod模板的規(guī)格信息

spec:
  ……
  template:
    spec:
      ……

這一部分通常是我們主要填寫的，因?yàn)閮?nèi)容較多，目前不展開(kāi)介紹了，以后用到我們?cè)僭敿?xì)說(shuō)明。
現(xiàn)在我們寫一個(gè)代碼中的簡(jiǎn)單示例

                Spec: coreV1.PodSpec{
                    Containers: []coreV1.Container{
                        {
                            Name:  deploymentName,
                            Image: image,
                            Ports: []coreV1.ContainerPort{
                                {
                                    ContainerPort: portNum,
                                },
                            },
                        },
                    },
                }

1.6 DeploymentStatus

所在包："k8s.io/api/apps/v1"

type DeploymentStatus struct {
    ObservedGeneration  int64                 `json:"observedGeneration,omitempty" protobuf:"varint,1,opt,name=observedGeneration"`
    Replicas            int32                 `json:"replicas,omitempty" protobuf:"varint,2,opt,name=replicas"`
    UpdatedReplicas     int32                 `json:"updatedReplicas,omitempty" protobuf:"varint,3,opt,name=updatedReplicas"`
    ReadyReplicas       int32                 `json:"readyReplicas,omitempty" protobuf:"varint,7,opt,name=readyReplicas"`
    AvailableReplicas   int32                 `json:"availableReplicas,omitempty" protobuf:"varint,4,opt,name=availableReplicas"`

    CollisionCount      *int32                `json:"collisionCount,omitempty" protobuf:"varint,8,opt,name=collisionCount"`
}

deployment的狀態(tài)，入門中不必過(guò)多關(guān)注

1.7 對(duì)照yml文件示例

附原生k8s集群上一個(gè)deployment 信息，大家可以對(duì)照理解一下以上結(jié)構(gòu)體

func (DeploymentInterface) List(ctx context.Context, opts v1.ListOptions) (*v1.DeploymentList, error)

語(yǔ)法示例

deploymentList,err = clientSet.AppsV1().Deployments(namespaceName).List(context.TODO(), metaV1.ListOptions{})

完整示例

創(chuàng)建函數(shù)

package crowK8S
import (
    "context"
    appsV1 "k8s.io/api/apps/v1"
    metaV1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
)
func GetDeploymentList(clientSet *kubernetes.Clientset,namespaceName string)(deploymentList *appsV1.DeploymentList,err error)  {
    deploymentList,err = clientSet.AppsV1().Deployments(namespaceName).List(context.TODO(), metaV1.ListOptions{})
    if err != nil{
        return nil, err
    }
    return deploymentList, err
}

說(shuō)明：如果namespaceName 為空字串，則查所有namespace

    "go-k8s/crowK8S"
)
func main()  {
    clientSet,err := crowK8S.ConnectK8s()
    if err !=nil {
        fmt.Println(err)
    }
    deploymentList,err := crowK8S.GetDeploymentList(clientSet,"kube-system")
    if err != nil {
        fmt.Println(err)
    }
    for _,deployment := range deploymentList.Items{
        fmt.Printf("%+v\n",deployment.Name)
    }
}

3. Get Deployment

結(jié)果輸出

說(shuō)明：打印是一個(gè)json字串，以下是我格式化后的結(jié)果：

func (DeploymentInterface) Delete(ctx context.Context, name string, opts v1.DeleteOptions) error

語(yǔ)法示例

err = clientSet.AppsV1().Deployments(namespaceName).Delete(context.TODO(),deploymentName,metaV1.DeleteOptions{})

完整示例

package crowK8S
import (
    "context"
    metaV1 "k8s.io/apimachinery/pkg/apis/meta/v1"
