This topic describes how to use the EDAS console to upgrade an application that is hosted on ECS clusters at a time.

Procedure

  1. Log on to the EDAS console.
  2. In the left-side navigation pane, click Applications.
  3. On the Applications page, select a region in the top navigation bar and select a namespace from the Namespace drop-down list. From the Cluster Type drop-down list, select ECS Cluster. Then, click the name of the required application in the application list.
  4. On the Basic Information page of the application, click Deploy Application in the upper-right corner.
  5. On the Select Deployment Mode page, click Start Deployment next to Regular Release (Single-batch/Multi-batch).
  6. On the Regular Release (Single-batch/Multi-batch) page, set the deployment package and other required parameters for the current application version, and specify the release policy. Then, click OK.
    1. Set the deployment package and other parameters for the current application version.
      Parameter Description
      Deployment Method The deployment method of the application is used when the application is deployed for the first time. This method cannot be modified. For example, a JAR package is used when the application is deployed for the first time. You can specify only JAR as the deployment method when you upgrade the application.
      Note If you set Deployment Method to Historical Versions, the application is rolled back to its previous version. For more information, see Roll back an application.
      File Uploading Method You can upload a JAR or WAR package, or specify a JAR or WAR package address. The deployment package type depends on the deployment package that is used when you deploy the application for the first time.
      • If you select Upload JAR Package or Upload WAR Package, click Select File and upload the deployment package of the current application version.
      • If you select JAR Package Address or WAR Package Address, enter the IP address of the deployment package in the field. However, you must first upload the application to a cloud service, such as Object Storage Service (OSS).
      Version The current application version. You can enter the version number or click Use Timestamp as Version Number.
      Description The description of the current version.
    2. Configure a release policy.
      Parameter Description
      Group The instance groups that you want to release in stages.
      • If the current application has only one group, select All Groups from the Group drop-down list. The maximum number of instances of the current application is displayed in the bracket after All Groups. The Group drop-down list also includes Default Group, which is the same as All Groups.
      • If the current application has multiple groups, select a group as needed.
        Note If you select All Groups, all instances in all groups of the application are upgraded based on the Batches per Group parameter set below.
      Batches per Group The number of batches in the group. If you release all of the application at one time, set the value to 1 Batches.
      Batch Mode If you set Batches per Group to 1 Batches, this parameter is set to Automatic by default.
      Java Environment Valid values: Open JDK 8, Open JDK 7, and Dragonwell 8. Set this parameter as needed.
    3. Click OK.
      After the release is started, the Change Details page appears. On the Change Details page, you can view the progress and status of the release. For more information, see View application changes.

Verify the result

  1. View change records.
    1. On the application details page, click Change Records in the left-side navigation pane.
    2. On the Change Records page, check whether the value in the Change Status column is Executed.
      • If the value is Executed, the application is released.
      • If the value is Executed failed, the application fails to be released. You can click View in the Actions column to view the change records and troubleshoot the issue.
  2. View application details.
    1. On the application details page, click Basic Information in the left-side navigation pane.
    2. On the Basic Information page, click the Basic Information tab. In the Application Information section of the Basic Information tab, check whether the Deployment Package parameter indicates the latest deployment package.
