c# - 如何在 C# 中使用 kubernetes-client 创建 k8s 部署？

Question

我在这一行收到 Microsoft.Rest.HttpOperationException: 'Operation returned an invalid status code 'BadRequest''。

var result = client.CreateNamespacedDeployment(部署, 命名空间);

Kubernetes-client有少量好的资源，大部分都是用java、python等其他语言写的。所以我指的是这些文档。

这是我到目前为止的实现。

        V1Deployment deployment = new V1Deployment()
        {
            ApiVersion = "extensions/v1beta1",
            Kind = "Deployment",
            Metadata = new V1ObjectMeta()
            {
                Name = "...",
                NamespaceProperty = env,
                Labels = new Dictionary<string, string>()
                {
                    { "app", "..." }
                }
            },
            Spec = new V1DeploymentSpec
            {
                Replicas = 1,
                Selector = new V1LabelSelector()
                {
                    MatchLabels = new Dictionary<string, string>
                    {
                        { "app", "..." }
                    }
                },
                Template = new V1PodTemplateSpec()
                {
                    Metadata = new V1ObjectMeta()
                    {
                        CreationTimestamp = null,
                        Labels = new Dictionary<string, string>
                        {
                             { "app", "..." }
                        }
                    },
                    Spec = new V1PodSpec
                    {
                        Containers = new List<V1Container>()
                        {
                            new V1Container()
                            {
                                Name = "...",
                                Image = "...",
                                ImagePullPolicy = "Always",
                                Ports = new List<V1ContainerPort> { new V1ContainerPort(80) }
                            }
                        }
                    }
                }
            },
            Status = new V1DeploymentStatus()
            {
                Replicas = 1    
            }
        };

        var result = client.CreateNamespacedDeployment(deployment, namespace);

我想知道如何使用 kubernetes-client 创建 kubernetes 部署的正确方法，我也想知道这个问题的原因。

为了完全清楚和 future 的访问者，值得一提的是，在使用您的代码示例时，从 API 服务器返回的错误请求错误(代码:400)背后究竟是什么:

"the API version in the data (extensions/v1beta1) does not match the expected API version (apps/v1)"

解决方案:

 ApiVersion = "extensions/v1beta1" -> ApiVersion = "apps/v1"

完整代码示例:

 private static void Main(string[] args)
        {
            var k8SClientConfig = new KubernetesClientConfiguration {  Host = "http://127.0.0.1:8080" };
            IKubernetes client = new Kubernetes(k8SClientConfig);

            ListDeployments(client);

            V1Deployment deployment = new V1Deployment()
            {
                ApiVersion = "apps/v1",
                Kind = "Deployment",
                Metadata = new V1ObjectMeta()
                {
                    Name = "nepomucen",
                    NamespaceProperty = null,
                    Labels = new Dictionary<string, string>()
                {
                    { "app", "nepomucen" }
                }
                },
                Spec = new V1DeploymentSpec
                {
                    Replicas = 1,
                    Selector = new V1LabelSelector()
                    {
                        MatchLabels = new Dictionary<string, string>
                    {
                        { "app", "nepomucen" }
                    }
                    },
                    Template = new V1PodTemplateSpec()
                    {

                        }
                        },
                        Spec = new V1PodSpec
                        {
