Huawei Cloud Container Service Interconnection Guide: Java code examples to quickly implement interfaces

Introduction:
With the rapid development of cloud computing and container technology, more and more enterprises are beginning to integrate applications and services Deployed in a container. HUAWEI CLOUD Container Service is a container management service launched by Huawei Cloud, providing a highly available and elastically scalable container operating environment. This article will introduce you how to use Java code examples to quickly implement interface docking with Huawei Cloud Container Service.

Step 1: Activate Huawei Cloud Container Service
Before using Huawei Cloud Container Service, you first need to activate the container service on the Huawei Cloud platform. Log in to the Huawei Cloud console, select "Containers and Microservices" under the "Products and Services" menu, click "Cloud Container Service", and follow the guidance to activate it.

Step 2: Create a Java project
Create a new Java project in the IDE, such as using Eclipse. Add the dependency of Huawei Cloud SDK to the project.

<dependency>
    <groupId>com.huaweicloud</groupId>
    <artifactId>huaweicloud-sdk-java</artifactId>
    <version>1.0.0</version>
</dependency>

Step 3: Write Java code example
Use the API provided by Huawei Cloud SDK to connect to the interface of Huawei Cloud Container Service.

import com.huaweicloud.sdk.core.auth.BasicCredentials;
import com.huaweicloud.sdk.core.auth.ICredential;
import com.huaweicloud.sdk.core.http.HttpConfig;
import com.huaweicloud.sdk.core.http.HttpRequestConfig;
import com.huaweicloud.sdk.core.http.accept.MediaType;
import com.huaweicloud.sdk.core.exception.SdkException;
import com.huaweicloud.sdk.kps.v3.KpsClient;
import com.huaweicloud.sdk.kps.v3.model.*;
import java.util.ArrayList;
import java.util.List;

public class HuaweiCloudKPSExample {

    public static void main(String[] args) {

        // 创建华为云KPS客户端
        // 替换AK和SK为您的华为云账号凭证
        ICredential credential = new BasicCredentials()
            .withAk("your-access-key")
            .withSk("your-secret-key");

        HttpConfig httpConfig = HttpConfig.getDefaultHttpConfig();
        HttpRequestConfig requestConfig = HttpRequestConfig.getDefaultRequestConfig();

        KpsClient kpsClient = KpsClient.newBuilder()
            .withCredential(credential)
            .withHttpConfig(httpConfig)
            .withHttpRequestConfig(requestConfig)
            .build();

        try {
            // 创建密钥对
            CreateKeyPairRequest createKeyPairRequest = new CreateKeyPairRequest()
                .withBody(new CreateKeyPairRequestBody()
                    .withName("my-keypair")
                    .withPublicKey("ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDVN123lxL5CRbeKll8FJ4QhsFf5EvCtcHJdIj/2saTlYuJA+OS7d12b8Dv8zG5PZ2EyI39wQlTyRg3tJvs95+FHhG180WOZ8YdS5uACIKrDD2yDF6BE1TN92uabw6ImV3z74haS0XZfiIz7u7Z3yItRH0OXKSi72KjcVTMAjAbdqL8C2bU0Yv0+2dFVst/ajJnXxekUqmp4RnIP6Jg5flvWY6+pCtlWgFdYBcRNGpzHlAXdNIawD4FyX88s5JtN0fsK4b0hlwL3t+HYKqv1eXPb1fF2RB8WolOixitRGINdxUBnxSsf9AehVUqCz8vwlO9bbaEuptOXvPnL5P9SplwUHH your-email@example.com"))
                .withContentType(MediaType.APPLICATION_JSON);

            CreateKeyPairResponse createKeyPairResponse = kpsClient.createKeyPair(createKeyPairRequest);
            System.out.println("Successfully created key pair: " + createKeyPairResponse.getKeypair().getName());

        } catch (SdkException e) {
            e.printStackTrace();
        }
    }
}

Step 4: Run the code example
Set the access key (AccessKey and SecretKey) of the Huawei Cloud account and run the code example. your-access-key and your-secret-key in the code example need to be replaced with the access key of your Huawei Cloud account.

Successfully created key pair: my-keypair

If the code example runs successfully, you will see output showing that a key pair was successfully created.

Conclusion:
Through the above steps, you can easily and quickly implement interface docking with Huawei Cloud Container Service through Java code examples. You can use the rich APIs provided by Huawei Cloud SDK to implement the integration and development of more container service functions based on your business needs. I hope this article will help you understand and use Huawei Cloud Container Service, and I wish you more success on the road to containerized application development.
