Creating a Batch Clone Release Task

This avoids complex and repeated configurations because multiple microservice components may have same configurations, for example, scheduling policy, AS policy, data storage, log storage, and lifecycle configurations, and only minor differences need to be modified. ServiceStage allows you to create a batch clone release task, so that you can add similar components that already exist in the current service environment to this release task, improving component deployment efficiency and user experience.

1. Log in to ServiceStage.
2. Choose Release Management > Create Release Task.
3. Configure the release task by referring to the following table. Parameters marked with an asterisk (*) are mandatory.

   Parameter	Description
   *Release Task	Name of a release task. Enter 2 to 64 characters. Start with a letter and end with a letter or digit. Only use letters, digits, underscores (_), and hyphens (-).
   Description	Description of a release task. Enter up to 128 characters.

4. Select Bulk Clone for Operation Type.
5. Set Best Effort Policy.

   Click to enable Best Effort Policy. If a component fails to be released, continue to release other components.

6. Click Add Component.
7. Select the components to be added to the release task and click OK.
   

   • A maximum of 64 components can be added to a batch clone release task.
   • Only container-deployed components whose status is Running, Not ready, Stopped, Unknown, or Abnormal can be selected.

8. Reset the version configurations of each component by referring to the following table.

   Parameter	Description
   Component	Component name. Enter 2 to 64 characters. Start with a letter and end with a letter or digit. Only use letters, digits, underscores (_), and hyphens (-). Components with the same name in different applications can be deployed in the same environment. Components with the same name in the same application can be deployed in different environments.
   Component Version	Version number of a component. By default, the version number is the time when you finish 7. 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. You can also customize the version number 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. NOTE: You can perform the following operations to synchronize component versions in batches: Move the cursor to the Component Version text box of the specified component and click . Select other components whose versions need to be synchronized. Click OK.
   Application	Select the application to which the component belongs. You can perform the following operations to synchronize the applications to which components belong in batches: Move the cursor to the Application drop-down list of the specified component and click . Select other components whose applications need to be synchronized. Click OK.
   Environment	Select the component deployment environment. Only the Kubernetes environment can be selected. NOTICE: If the component has been bound to a specified microservice engine, distributed cache, or cloud database instance but the specified instance is not bound to the environment selected for the component, an error is reported during advanced settings pre-check. You can perform the following operations to synchronize the environments to which components belong in batches: Move the cursor to the Environment drop-down list of the specified component and click . Select other components whose environments need to be synchronized. Click OK. After the environment is reset, the cluster to which the component belongs is changed to the cluster bound to the new environment, and the namespace to which the component belongs is changed to the default namespace of the cluster bound to the new environment.
   Cluster	Select the CCE cluster where the component is deployed and running. You can perform the following operations to synchronize the clusters to which components belong in batches: Move the cursor to the Cluster drop-down list of the specified component and click . Select other components whose clusters need to be synchronized. Click OK. After the cluster is set, the cluster is changed only when the selected cluster is bound to the environment to which the component belongs. In addition, the namespace to which the component belongs is changed to the default namespace of the new cluster.
   Namespace	Select the namespace of the CCE cluster in the environment where the build is executed, which is used to isolate build data. For details, see Managing Namespaces. You can perform the following operations to synchronize the namespaces to which components belong in batches: Move the cursor to the Namespace drop-down list of the specified component and click . Select other components whose namespaces need to be synchronized. Click OK. After the namespace is set, the namespace is changed only when the selected namespace exists in the cluster to which the component belongs.
   Image Package	Click . Select the component source again. For details, see Component Source. You can customize a container name. 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.
   Instances	Set the number of running component instances. The value range is 1–200. You can perform the following operations to synchronize the number of component instances in batches: Move the cursor to the Instances text box of the specified component and click . Select other components whose number of component instances need to be synchronized. Click OK.
   Deployment Sequence	Set the deployment sequence of all components to be added to the release task. If the selected components depend on each other, for example, the startup of a component depends on other components, set Deployment Sequence so that the depended components are deployed first. For example, for components A, B, and C to be added to the release task, the startup of component A depends on components B and C. Therefore, set Deployment Sequence of components B and C to 1, and set Deployment Sequence of component A to 2. If the components do not depend on each other, retain the default value of Deployment Sequence. All components will be deployed in the same batch.

9. Set the component build parameters.
   This parameter is available when the technology stack type is Java, Tomcat, Node.js, Python, or PHP.

   1. Locate the target component and click Build in the Operation column.
   2. Set the parameters by referring to the following table. Parameters marked with an asterisk (*) are mandatory.

      Parameter	Description
      *Command	If the component source is Source code repository, set Command based on service requirements. 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	If the component source is Source code repository, set Dockerfile Address based on service requirements. 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.
      *Organization	An organization is used to manage images generated during component build.
      *Build	Select the type of the environment used to build an image. The build environment must be a Kubernetes environment, and can access the Internet. You are advised to select Use current environment. If the CCE cluster in the current environment cannot access the Internet and you have planned an independent build environment, you can select Use independent environment. Use independent environment: Use an independent build environment to build an image. The CCE clusters in the independent build environment and in the current component deployment environment must have the same CPU architecture. Otherwise, the component deployment fails. Use current environment: Use the deployment environment to which the component belongs to build an image. In the current environment, masters and nodes in the CCE cluster must have the same CPU architecture. Otherwise, the component build fails.
      *Environment	If Use independent environment is selected for Build, select an independent build environment different from that to which the component belongs. If Use current environment is selected for Build, select the deployment environment to which the component belongs.
      *Namespace	Select the namespace of the CCE cluster in the environment where the build is executed, which is used to isolate build data. For details, see Managing Namespaces.
      Node Label	In the following cases, set a node label to deliver the build job to the fixed node bound with an EIP to ensure that the component can be successfully built and deployed: If Use independent environment is selected for Build, set a node label to deliver the build job to the node in the independent environment, to ensure that the node CPU architecture is the same as that of the node in the current component deployment environment. If Use current environment is selected for Build and the CPU architecture of a node is different from that of the master node in the environment, set a node label to deliver the build job to the node that has the same CPU architecture as the master node. For details about how to add a label, see Managing Node Labels.
