Upgrading a Component in Single-batch Release Mode

After a component is created and deployed, you can upgrade all instances of a component at a time in single-batch release mode.

During the upgrade, component services will be interrupted. This is applicable only to the test upgrade scenario or the upgrade scenario where services are to be stopped.

For details about how to upgrade multiple component versions of the same application in batches, see Upgrading Components in Batches.

Prerequisites

Upgrading a Component in Single-batch Release Mode

  1. Log in to ServiceStage.
  2. Use either of the following methods to go to the component Overview page.

    • On the Application Management page, click the application to which the component belongs, and click the target component in Component List.
    • On the Component Management page, click the target component.

  3. Click Upgrade in the upper right corner of the page.
  4. Select Single-batch Release.
  5. Click Next and set the component version configuration information by referring to the following table. Parameters marked with an asterisk (*) are mandatory.

    Parameter

    Description

    Stack

    Select a component technology stack and version.

    For details, see Technology Stack.

    *YAML Mode

    Uses YAML configurations to upgrade components.

    • Disabled: The UI configurations are used to upgrade components.
    • Enabled: The YAML configurations are used to upgrade components. The latest load information of the component is automatically synchronized from CCE where the target component is deployed for component upgrade after modification. Alternatively, click Import YAML File to import the edited YAML configuration file of the target component.
    NOTE:

    If YAML configurations are used to upgrade components, the parameters in the YAML configuration file are described in Deployment.

    *Software Package/Image

    The value is fixed to the component source selected during component creation and deployment.

    • YAML Mode disabled: If you select Source code repository, create authorization by referring to Creating Repository Authorization and set the code source. If you select a software package or image package, the option is fixed to the software package type (JAR, WAR, or ZIP) or image package type selected during component creation and deployment. It is determined by the selected technology stack type. For details, see Table 1.
    • YAML Mode enabled: If you select Source code repository, create authorization by referring to Creating Repository Authorization and set the code source. If you select a software package, the option is fixed to the software package type (JAR, WAR, or ZIP) selected during component creation and deployment. It is determined by the selected technology stack type. For details, see Table 1.

      This parameter is unavailable when the technology stack is Docker.

    *Upload Method

    • YAML Mode disabled: If the component source is software package or image package, select an uploaded software package or image package. For details about the upload method, see Component Source.
      NOTE:

      If you select an image package:

      • You can customize the container name. The name contains 1 to 63 characters, including lowercase letters, digits, and hyphens (-), and must start with a lowercase letter and end with a lowercase letter or digit.
      • Click in the upper right corner of the selected image package to change the image package source.
    • YAML Mode enabled: If the component source is software package, select an uploaded software package. For details about the upload method, see Component Source. This parameter is unavailable when the technology stack is Docker.
    • If the component source is software package and Custom file address is selected, perform the following operations:
      1. Enter the custom HTTP/HTTPS file download address of the software package.
      2. Determine whether to enable authentication.

        If authentication is disabled, any user can download the software package in the custom file address by default.

        Click to enable authentication. Only authenticated users can download the software package in the custom file address. Authentication mode can be User name and password authentication or User-defined Header Authentication. The authentication mode and the corresponding authentication parameters are determined by the authentication mode supported by the server where the custom file directory is located.

    Image Access Credential

    • You can select up to 16 image access credentials.
    • Click Create Secret to create an image access credential. Secret Type must be kubernetes.io/dockerconfigjson. For details, see Creating a Secret.

    *Command

    This parameter is mandatory when YAML Mode is disabled, the component source is Source code repository, the component is deployed in the Kubernetes environment, and the selected technology stack type is Java, Tomcat, Node.js, Python, or PHP.

    • Default command or script: preferentially executes build.sh in the root directory. If build.sh does not exist, the code will be compiled using the common method of the selected language. Example: mvn clean package for Java.
    • Custom command: Commands are customized using the selected language. Alternatively, the default command or script is used after build.sh is modified.
      NOTICE:
      • If Custom command is selected, exercise caution when inputting sensitive information in the echo, cat, or debug command, or encrypt sensitive information to avoid information leakage.
      • To run the compilation command in the project subdirectory, you need to go to the project subdirectory and then run other script commands. Example:

        cd ./weather/

        mvn clean package

    *Dockerfile Address

    This parameter is mandatory when YAML Mode is disabled, the component source is Source code repository, the component is deployed in the Kubernetes environment, and the selected technology stack type is Java, Tomcat, Node.js, Python, or PHP.

    Dockerfile Address is the directory where the Dockerfile is located relative to the root directory (./) of the project. The Dockerfile is used to build an image.

    If Dockerfile Address is not specified, the system searches for the Dockerfile in the root directory of the project by default. If the Dockerfile does not exist in the root directory, the system automatically generates the Dockerfile based on the selected operating environment.

    *Component Version

    Component version number, which can be automatically generated or customized.

    • Automatically-generated: Click Generate. By default, the version number is the timestamp when you click Generate. The format is yyyy.mmdd.hhmms, where s is the ones place of the second in the timestamp. For example, if the timestamp is 2022.0803.104321, the version number is 2022.0803.10431.
    • Customized: Enter a value in the format of A.B.C or A.B.C.D. A, B, C, and D are natural numbers. For example, 1.0.0 or 1.0.0.0.
      NOTICE:

      The customized version number must be unique and cannot be the same as any historical version number of the component. Otherwise, the current deployment record will overwrite the historical deployment record of the same version.

    *Container Name

    This parameter is mandatory when the technology stack is not Docker and YAML Mode is disabled.

    The name contains 1 to 63 characters starting with a lowercase letter and ending with a lowercase letter or digit. Only lowercase letters, digits, and hyphens (-) are allowed.

    Resources

    This parameter is available when YAML Mode is disabled.

    You can customize CPU and Memory to set their quota, and set the maximum/minimum number of CPU cores and memory size (GiB) that can be used by components. In this way, you can set the number of resources required by each component instance.

    When resource Request is specified for a component instance, CCE uses this information to determine the node to which the component instance is scheduled. When resource Limit is specified for a component instance, CCE ensures that the resources occupied by the running component instance do not exceed the limit. CCE will also reserve the requested number of system resources for the component instance. For details about how to configure them, see Resource Management.

    To modify them, select the item to be changed and enter a new value. Unselected parameters indicate no restriction.

    NOTE:

    If the source of the component selected for Upload Method is image package and multi-container deployment is enabled, set this parameter for each container instance as required.

    JVM Parameters

    This parameter is available when YAML Mode is disabled and the technology stack type is Java or Tomcat. It configures the memory size during Java code running.

    Enter the JVM parameter, for example, -Xms256m -Xmx1024m. Multiple parameters are separated by spaces. If the parameter is left blank, the value is empty.

    Tomcat

    This parameter is available when YAML Mode is disabled and the technology stack type is Tomcat. It configures parameters such as the request path and port number of Tomcat.

    1. Select Tomcat. The Tomcat dialog box is displayed.
    2. Click Use Sample Code and edit the template file based on service requirements.
      NOTE:

      In Tomcat configuration, the default server.xml configuration is used. The context path is /, and no application path is specified.

      If you need to customize an application path, customize the Tomcat context path by referring to How Do I Customize a Tomcat Context Path?

    3. Click OK.

    Cloud Service Settings

    If YAML Mode is disabled, set this parameter as required by referring to Managing Cloud Service Settings of a Container-Deployed Component.

    NOTICE:

    Components bound to RDS cannot be deleted. Otherwise, the upgrade will fail.

    Container Settings

    If YAML Mode is disabled, set this parameter as required by referring to Managing Container Settings of a Container-Deployed Component.

    Application Settings

    If YAML Mode is disabled, set this parameter as required by referring to Managing Application Settings of a Container-Deployed Component.

    NOTE:

    If the source of the component selected for Upload Method is image package and multi-container deployment is enabled, set this parameter for each container instance as required.

    Advanced Settings

    If YAML Mode is disabled, set this parameter as required by referring to Managing Advanced Settings of a Container-Deployed Component.

  6. Click Upgrade.

    • Wait until the component status changes from Upgrading/Rolling back the component to Running, indicating that the component has been upgraded.
    • On the Deployment Records page, view the deployment logs.
