Java Programming Guide: Huawei Cloud Container Service Interface Interconnection Example Sharing

Introduction:
With the continuous development of cloud computing technology, containerization technology has been widely used in practice. Huawei Cloud Container Service is a cloud service that provides elasticity, high availability, security, reliability, and convenient management, making it easier for developers to build, deploy, and manage containerized applications. This article mainly introduces how to use Java language to connect to the interface of Huawei Cloud Container Service to better implement containerized applications.

1. Environment preparation
Before starting, we first need to prepare the following environment:

1. JDK environment
2. Maven dependency management tool
3. Huawei Cloud account and corresponding Access Key and Secret Key

2. Introducing dependencies
Next, we need to introduce the Java SDK dependency of Huawei Cloud Container Service in the project's pom.xml file :

<dependencies>
    <dependency>
        <groupId>com.huaweicloud.sdk</groupId>
        <artifactId>huaweicloud-sdk-core</artifactId>
        <version>3.1.0</version>
    </dependency>
    <dependency>
        <groupId>com.huaweicloud.sdk</groupId>
        <artifactId>huaweicloud-sdk-servicename</artifactId>
        <version>3.1.0</version>
    </dependency>
</dependencies>

Please note that "servicename" in the above code is replaced with the name of the specific Huawei Cloud service that needs to be used. For example, the name of the container service is "ces".

3. Interface Call
Next, we can use Java code to connect to the interface of Huawei Cloud Container Service. The following is a simple example showing how to create a container instance:

import com.huaweicloud.sdk.core.auth.BasicCredentials;
import com.huaweicloud.sdk.core.exception.SdkException;
import com.huaweicloud.sdk.core.http.HttpConfig;
import com.huaweicloud.sdk.servicename.v1.ServiceNameClient;
import com.huaweicloud.sdk.servicename.v1.model.Container;
import com.huaweicloud.sdk.servicename.v1.model.CreateContainerRequest;
import com.huaweicloud.sdk.servicename.v1.model.CreateContainerResponse;

public class ContainerServiceExample {

    public static void main(String[] args) {
        // 设置华为云接口的基本认证信息
        BasicCredentials credentials = new BasicCredentials()
                .withAk("<your-access-key>").withSk("<your-secret-key>");

        // 创建华为云容器服务的客户端
        ServiceNameClient client = ServiceNameClient.newBuilder()
                .withCredential(credentials)
                .withHttpConfig(HttpConfig.getDefaultHttpConfig())
                .build();

        try {
            // 创建容器的请求参数
            CreateContainerRequest request = new CreateContainerRequest()
                    .withName("example-container")
                    .withImage("huaweicloud/your-image:latest")
                    .withFlavor("s1.small")
                    .withNetworks(Arrays.asList("network-id"))
                    .withSecurityGroups(Arrays.asList("security-group-id"));

            // 调用华为云容器服务的接口进行容器创建
            CreateContainerResponse response = client.createContainer(request);

            // 输出创建结果
            if (response.getJobId() != null) {
                System.out.println("Container creation request submitted successfully.");
                System.out.println("Job ID: " + response.getJobId());
            } else {
                System.out.println("Container creation failed.");
            }
        } catch (SdkException e) {
            System.out.println("Failed to create container: " + e.getMessage());
        } finally {
            client.close();
        }
    }
}

Please note that in the above code, "f5036707ec9fcd4a220e0f92e27fffce" and "56dc264c8a546607c83b35ff5b92bd5e" Replace with your own Access Key and Secret Key.

4. Summary
This article introduces how to use Java language to connect to the interface of Huawei Cloud Container Service, and provides a simple sample code for container creation. Through these sample codes, we can better understand and master how to use Java to implement operations on container services. Of course, this is just a simple example. Actual use may require more parameters and operations, and we can adjust and expand accordingly according to specific needs. In actual development, we can complete more complex and detailed container management operations based on the API documents provided by Huawei Cloud and combined with specific business scenarios.

I hope this article will be helpful to developers who learn and use Huawei Cloud Container Service. I wish everyone will go further and further on the road of containerization technology and achieve more fruitful results!
