Enterprise Distributed Application Service:Deploy an application to an ECS cluster in single-release mode

Deploy the application

The following Java code deploys an application in single-release mode to an ECS cluster. All examples call the DeployApplication API operation with Batch set to 1 for single-release deployment.

For a full list of parameters, see DeployApplication.

// EDAS Container build package number for HSF applications.
// Call ListBuildPack to get ConfigId.
request.setBuildPackId(57);

import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.edas.model.v20170801.DeployApplicationRequest;
import com.aliyuncs.edas.model.v20170801.DeployApplicationResponse;

public class DeployApplication {

    public static void main(String[] args)  {
        // The AccessKey pair of an Alibaba Cloud account has permissions on all API operations.
        // Using these credentials to perform operations in EDAS is a high-risk operation.
        // We recommend that you use a RAM user to call API operations or perform routine O&M.
        // To create a RAM user, log on to the RAM console.
        // Get AccessKey credentials from environment variables.
        String aliyun_user_ak = System.getenv("ACCESS_KEY_ID");
        String aliyun_user_sk = System.getenv("ACCESS_KEY_SECRET");

        // Region where the application is deployed
        String region_id = "cn-hangzhou";

        DefaultProfile defaultProfile = DefaultProfile.getProfile(region_id, aliyun_user_ak, aliyun_user_sk);
        DefaultAcsClient client = new DefaultAcsClient(defaultProfile);

        DeployApplicationRequest request = new DeployApplicationRequest();

        // Application ID
        request.setAppId("6bbc57a2-a017-4bec-b521-49a15bd3****");

        // Deployment description
        request.setDesc("create by edas pop api");

        // Deployment type: use a URL to the package
        request.setDeployType("url");

        // URL of the JAR or WAR file (stored in OSS)
        request.setWarUrl("https:doc***.oss-cn-hangzhou.aliyuncs.com/sc-****-D-0.0.1-SNAPSHOT.jar");

        // Package version (max 64 characters, timestamp recommended)
        request.setPackageVersion("1619094147");

        // Deploy group ID. Set to "all" to deploy to all groups.
        // Call the ListDeployGroup operation to get the ID of a specific group.
        request.setGroupId("all");

        // Number of release phases. Set to 1 for single-release.
        request.setBatch(1);

        // Release type: 0 = automatic, 1 = manual
        request.setReleaseType((long) 0);

        // Application component ID (Spring Cloud/Dubbo only):
        //   4 = Apache Tomcat 7.0.91
        //   7 = Apache Tomcat 8.5.42
        //   5 = OpenJDK 1.8.x
        //   6 = OpenJDK 1.7.x
        request.setComponentIds("5");

        try {
            DeployApplicationResponse response = client.getAcsResponse(request);
            System.out.println("Message=" + response.getMessage() + "\nChangeOrderId=" + response.getChangeOrderId());
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            e.printStackTrace();
        }
    }
}

Replace the following placeholders with your values:

Message=success
ChangeOrderId=f32db5e3-a105-412c-9168-6f7c5295****

Verify the deployment

After the deployment starts, call the GetChangeOrderInfo API operation to check the status. For the full parameter reference, see GetChangeOrderInfo.

Example response:

{
  "Message": "success",
  "RequestId": "9C487FE4-F188-45EC-87A5-8BD3D655568F",
  "Code": 200,
  "changeOrderInfo": {
    "Status": 2,
    "Desc": "create by edas pop api",
    "PipelineInfoList": {
      ...
    }
  }
}

Check the changeOrderInfo.Status field to determine the deployment result:

A Status value of 2 confirms that the single-release deployment completed successfully.
