使用Kubernetes客户端go创建作业

目前，我有一段基于其他示例的go代码。我可以列出所有的豆荚，工作。。。等等，但是我遇到了一个相当棘手的问题，在Openshift上创建一个作业

我的代码的以下部分应该创建一个作业，我甚至得到了一个响应，但没有在提到的命名空间上创建作业：

func main() {
    var kubeconfig *string
    if home := homedir.HomeDir(); home != "" {
        kubeconfig = flag.String("kubeconfig", filepath.Join(home, ".kube", "config"), "(optional) absolute path to the kubeconfig file")
    } else {
        kubeconfig = flag.String("kubeconfig", "", "absolute path to the kubeconfig file")
    }
    flag.Parse()
    config, err := clientcmd.BuildConfigFromFlags("", *kubeconfig)
    if err != nil {
        panic(err)
    }
    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        panic(err)
    }
    jobsClient := clientset.BatchV1().Jobs("gitlab")
    job := &batchv1.Job{
        ObjectMeta: metav1.ObjectMeta{
            Name: "demo-job",
        },
        Spec: batchv1.JobSpec{
            Template: apiv1.PodTemplateSpec{
                Spec: apiv1.PodSpec{
                    Containers: []apiv1.Container{
                        {
                            Name:  "demo",
                            Image: "myimage",
                        },
                    },
                },
            },
        },
    }

    fmt.Println("Creating job... ")
    result1, err1 := jobsClient.Create(job)
    if err != nil {
        fmt.Println(err1)
        panic(err1)
    }
    fmt.Printf("Created job %q.\n", result1)

}

因此，我得到的是：

Created job "&Job{ObjectMeta:k8s_io_apimachinery_pkg_apis_meta_v1.ObjectMeta{Name:,GenerateName:,Namespace:,SelfLink:,UID:,ResourceVersion:,Generation:0,CreationTimestamp:0001-01-01 00:00:00 +0000 UTC,DeletionTimestamp:<nil>,DeletionGracePeriodSeconds:nil,Labels:map[string]string{},Annotations:map[string]string{},OwnerReferences:[],Finalizers:[],ClusterName:,Initializers:nil,},Spec:JobSpec{Parallelism:nil,Completions:nil,ActiveDeadlineSeconds:nil,Selector:nil,ManualSelector:nil,Template:k8s_io_api_core_v1.PodTemplateSpec{ObjectMeta:k8s_io_apimachinery_pkg_apis_meta_v1.ObjectMeta{Name:,GenerateName:,Namespace:,SelfLink:,UID:,ResourceVersion:,Generation:0,CreationTimestamp:0001-01-01 00:00:00 +0000 UTC,DeletionTimestamp:<nil>,DeletionGracePeriodSeconds:nil,Labels:map[string]string{},Annotations:map[string]string{},OwnerReferences:[],Finalizers:[],ClusterName:,Initializers:nil,},Spec:PodSpec{Volumes:[],Containers:[],RestartPolicy:,TerminationGracePeriodSeconds:nil,ActiveDeadlineSeconds:nil,DNSPolicy:,NodeSelector:map[string]string{},ServiceAccountName:,DeprecatedServiceAccount:,NodeName:,HostNetwork:false,HostPID:false,HostIPC:false,SecurityContext:nil,ImagePullSecrets:[],Hostname:,Subdomain:,Affinity:nil,SchedulerName:,InitContainers:[],AutomountServiceAccountToken:nil,Tolerations:[],HostAliases:[],PriorityClassName:,Priority:nil,DNSConfig:nil,},},BackoffLimit:nil,},Status:JobStatus{Conditions:[],StartTime:<nil>,CompletionTime:<nil>,Active:0,Succeeded:0,Failed:0,},}".

检查“gitlab”名称空间，没有新作业。

基于我过去所做的工作（您可以看到），我认为您可以在作业资源的ObjectMeta中指定名称空间。您可以将其放到jobsClient中

jobsClient := clientset.BatchV1().Jobs()
job := &batchv1.Job{
    ObjectMeta: metav1.ObjectMeta{
        Name: "demo-job",
        Namespace: "gitlab",
    },
    Spec: batchv1.JobSpec{
        Template: apiv1.PodTemplateSpec{
            Spec: apiv1.PodSpec{
                Containers: []apiv1.Container{
                    {
                        Name:  "demo",
                        Image: "myimage",
                    },
                },
            },
        },
    },
}

解决了这个问题，即使您没有得到任何错误，您也必须指定所有必需的字段，因此获取作业结果并查看是否可以手动创建对象

话虽如此，需要按如下方式创建上一个作业：

job := &batchv1.Job{
        ObjectMeta: metav1.ObjectMeta{
            GenerateName: "prometheus-webhook-",
            Namespace: "gitlab",
        },
        Spec: batchv1.JobSpec{
            Template: apiv1.PodTemplateSpec{
                ObjectMeta: metav1.ObjectMeta{
                    GenerateName: "prometheus-webhook-",
                },
                Spec: apiv1.PodSpec{
                    Containers: []apiv1.Container{
                        {
                            Name:  "ansible-job",
                            Image: "yourimage",
                        },
                    },
                    RestartPolicy: apiv1.RestartPolicyOnFailure,
                },
            },
        },
    }
