Defining the Deployment Order to Targets

Watch the video:

To Define the Deployment Order of Components to Targets

1. Create a Dynamic Property named deploy_after on every Target where you want to deploy the Component.
2. In the Value field, add the name of the Target where the Component has to be previously deployed.

   Note: Leave the value empty for the Target which are to be executed first.

   

   For example: The Component webapp has to be deployed in a sequential order to the Targets DeploymentTarget1, DeploymentTarget2 and DeploymentTarget3.

   • Dynamic Property added to DeploymentTarget1- name: deploy_after, value: empty
   • Dynamic Property added to DeploymentTarget2 - name: deploy_after, value: DeploymentTarget1.
   • Dynamic Property added to DeploymentTarget3 - name: deploy_after, value: DeploymentTarget2.

3. Create one Dynamic Property on the Component (for example, webapp) and name it deploy_after. Reference the deploy_after Dynamic Property defined on the Targets with the following expression:

   

4. Create four new CLI custom Actions with the following names:

   • Create Variable Object (to be used in the Application Workflow)
   • Remove Object (to be used in the Application Workflow)
   • Check Deployment Order Variable (to be used in the Component Workflow)
   • Write Value to VARA Object (to be used in the Component Workflow)
5. Remove the operating system jobs created within the Action and replace them with the scripts provided below.
6. Create the following Prompt Sets for the Actions:

   Action	Label	Variable Name
   Create Variable Object	Variable Name	&UC4RB_VARIABLE_NAME#
   	Folder	&UC4RB_VARIABLE_FOLDER#
   Remove Object	Variable Name	&UC4RB_VARIABLE_NAME#
   Check Deployment Order Variable	Variable Name	&UC4RB_VARIABLE_NAME#
   Write Value to VARA Object	Variable Name	&UC4RB_VARIABLE_NAME#
   	Key	&UC4RB_VARIABLE_KEY#
   	Value 1	&UC4RB_VARIABLE_VALUE#

7. Create a new Script object (for example, Create Variable Object).

8. Open it, select the Process tab and enter the following command.

   :SET &RET# = CREATE_OBJECT("VARA",&UC4RB_VARIABLE_NAME#,&UC4RB_VARIABLE_FOLDER#,"","I","C")

   Note: This command will automatically create a new VARA object to define the deployment order to the Targets.

9. Add the Script object to the Create Variable Object Action.
10. Add the Action to the beginning of the Application Workflow.
11. Create another Script object (for example, Remove Object).

12. Open it, select the Process tab and enter the following command:

    :SET &RET# = REMOVE_OBJECT(&UC4RB_VARIABLE_NAME#)

    Note: This command will delete the VARA object.

13. Add the Script object to the Remove Object Action.
14. Add the Action to the end of the Application Workflow:

    

15. Create another Script object (for example, Check Deployment Order Variable).

16. Open it, select the Process tab and enter the following command:

    :PRINT "Deploy Target After: &DEPLOY_AFTER#"

    :SET &TEST# = GET_VAR(&UC4RB_VARIABLE_NAME#, "DeployAfter")

    :PRINT "Test:&TEST#"

    :WHILE &TEST# <> &DEPLOY_AFTER#

    :  WAIT 5

    :  SET &TEST# = GET_VAR(&UC4RB_VARIABLE_NAME#, "DeployAfter")

    :  PRINT "Test:&TEST#"

    :ENDWHILE

    Note: This command will check if the Target referenced by the deploy_after property is set as a value for the key deployAfter in the VARA object.

17. Add the Script object to the Check Deployment Order Variable Action.

18. Add the Action to the beginning of the Component Workflow (for example, webapp).

19. Select the Action, go to the Prompt Sets tabs and enter the following value:

    DEPLOY_ORDER_&$TOP_PROCESSFLOW_RUNID#

20. Create another Script object (for example, Write Value to VARA Object).

21. Open it, select the Process tab and enter the following command:

    :PUT_VAR &UC4RB_VARIABLE_NAME#, &UC4RB_VARIABLE_KEY#, &UC4RB_VARIABLE_VALUE#

    Note: This command will write the value in the VARA object for a given key.

22. Add the Script object to the Write Value to VARA Object Action.
23. Add the Action to the end of the Component Workflow (for example, webapp).

24. Select the Action, go to the Prompt Sets tab and enter the following variable:

    DEPLOY_ORDER_&$TOP_PROCESSFLOW_RUNID#

25. Enter the Key DeployAfter

26. Enter the variable value (for example &TARGET_NAME#)

    

27. Go back to the Application Workflow and select the Component (for example, webapp).
28. Select the Variables tab and add two new rows to reference the deploy order and the Target names:

    

29. Execute the Application Workflow.

Note: Make sure the deployment order option parallel (default) is selected for the Component Workflow.
