Deleting an Instance

This section describes how to delete an instance using AK/SK authentication.

Replace the AK/SK in the sample code with the actual AK/SK. Use the setInstanceName method of the RunDeleteInstanceRequest class to specify the name of the instance you want to delete. After the configuration is complete, run the code.

1. The sample code for deleting an instance is as follows:

   import com.alibaba.fastjson.JSON;
   import com.huaweicloud.sdk.core.auth.ICredential;
   import com.huaweicloud.sdk.core.auth.BasicCredentials;
   import com.huaweicloud.sdk.core.exception.ConnectionException;
   import com.huaweicloud.sdk.core.exception.RequestTimeoutException;
   import com.huaweicloud.sdk.core.exception.ServiceResponseException;
   import com.huaweicloud.sdk.imagesearch.v1.ImageSearchClient;
   import com.huaweicloud.sdk.imagesearch.v1.model.RunDeleteInstanceRequest;
   import com.huaweicloud.sdk.imagesearch.v1.model.RunDeleteInstanceResponse;
   import com.huaweicloud.sdk.imagesearch.v1.region.ImageSearchRegion;
    
   /**
    * Delete an existing instance.
    */
   public class RunDeleteInstanceDemo {
       public static void main(String[] args) {
           //Set the obtained AK and SK.
           String ak = "<YOUR AK>";
           String sk = "<YOUR SK>";
           ICredential auth = new BasicCredentials()
               .withAk(ak)
               .withSk(sk);
           
           ImageSearchClient client = ImageSearchClient.newBuilder()
               .withCredential(auth)
               //Set the region. In this example, CN North-Beijing4 is used.
               .withRegion(ImageSearchRegion.valueOf("cn-north-4"))
               .build();
           RunDeleteInstanceRequest request = new RunDeleteInstanceRequest();
           //Set the instance name.
           request.setInstanceName("instance-name");
           try {
               RunDeleteInstanceResponse response = client.runDeleteInstance(request);
               System.out.println(JSON.toJSONString(response));
           } catch (ConnectionException e) {
               System.out.println(e.getMessage());
           } catch (RequestTimeoutException e) {
               System.out.println(e.getMessage());
           } catch (ServiceResponseException e) {
               System.out.println(e.getHttpStatusCode());
               System.out.println(e.getErrorCode());
               System.out.println(e.getErrorMsg());
           }
       }
   }

2. Execute the sample code. If the instance deletion result is displayed on the console, the code is successfully executed. For details, see Deleting an Instance.
