交argo的yaml

argo类型的则要麻烦一些,因为defaultClient不支持argo类型的。
会报错No resource type found for:argoproj.io/v1alpha1

com.fasterxml.jackson.databind.JsonMappingException: No resource type found for:argoproj.io/v1alpha1#Workflow

我们需要进行自定义资源才能提交argo类型的yaml。

首先需要查看集群中已有的crd。
使用命令

kubectl  get crd
kubectl  get crd |grep argo



java中查询已有的crd代码如下:

     try {
                      if (!client.supportsApiPath("/apis/apiextensions.k8s.io/v1beta1") && !client.supportsApiPath("/apis/apiextensions.k8s.io/v1")) {
                        System.out.println("WARNING this cluster does not support the API Group apiextensions.k8s.io");
                        return "fail";
                      }
                      CustomResourceDefinitionList list = client.customResourceDefinitions().list();
                      if (list == null) {
                        System.out.println("ERROR no list returned!");
                        return "fail";
                      }
                      List<CustomResourceDefinition> items = list.getItems();
                      for (CustomResourceDefinition item : items) {
                        System.out.println("CustomResourceDefinition " + item.getMetadata().getName() + " has version: " + item.getApiVersion());
                      }
                    } catch (KubernetesClientException e) {
                      System.out.println("Failed: " + e);
                      e.printStackTrace();
                    }



结果输出如下:
