Use Deployment Manager to create continuous integration and continuous delivery (CI/CD) pipelines, which automate tasks so that you can quickly deploy high-quality software to production.

On the orchestration server, release managers configure CI/CD pipelines for their Pega^® Platform applications from the DevOps landing page. The landing page displays all the running and queued application builds, branches that are to be merged, and reports that provide information about your DevOps environment.

Adding an application pipeline on the orchestration server

When you add a pipeline, you specify both pre-merge and post-merge criteria. For example, you can specify that a branch must be peer-reviewed before it can be merged on the remote development system, and you can specify that Pega unit tests are run after a branch is merged and is in the QA stage of the pipeline.

1. In the Designer Studio footer, click DevOps.
2. Click Add application pipeline.
3. Optional: Specify tasks that must be completed before a branch can be merged in the pipeline:
   1. Click Add task.
   2. From the Type list, select Pega, and then specify the task that you want to perform.
      • To specify that a branch must meet a compliance percentage before it can be merged:
        1. From the Task list, select Check for guardrails.
        2. In the Weighted Compliance Score field, enter the minimum required compliance percentage.
        3. Click Submit.
      • To specify that a branch must be reviewed before it can be merged:
        1. From the Task list, select Branch review.
        2. Click Submit.
   3. Optional: To start a build when a branch is merged, select the Trigger build on merge check box.

One of the following results occurs:

• If no build is running in the pipeline, and a branch is successfully merged, the build is started by the operator who is logged in to the orchestration server.
• If a build is running, and a branch is successfully merged, the build is queued for processing. The build will be started by using the operator ID that you defined in this Dynamic System Setting.

4. Optional: To skip a build life cycle stage, clear its check box.
5. Optional: In the build life cycle stages, specify the tasks to be performed during each stage of the pipeline:
   1. Click Add task.
   2. From the Type list, select Pega, and then specify the task that you want to perform:
      • To run all Pega unit tests in the application, from the Task list, select Pega unit testing.
      • To run a Jenkins job, do the following actions:
        1. From the Task list, select Jenkins.
        2. In the Job name field, enter the name of the Jenkins job (which is the name of the Jenkins build) that you want to run.
        3. In the Token field, enter the Jenkins authentication token.
        4. In the Parameters field, enter parameters, if any, to send to the Jenkins job.

• To add a manual step that a user must perform in the pipeline, do the following tasks:
  1. From the Task list, select Manual.
  2. In the Job name field, enter text that describes the action that you want the user to take.
  3. In the Assigned to field, press the Down Arrow key and select the operator ID to assign the task to.

6. Click Review pipeline. The system generates tasks, which you cannot delete, that the pipeline always performs, for example, deploying the application to each stage in the pipeline.
7. Click Next.
8. If you added a Jenkins step, specify Jenkins server information in the Add application dialog box, in the Jenkins server section:
   1. In the URL field, enter the URL of the Jenkins server.
   2. In the Authentication profile field, press the Down Arrow key and select the authentication profile on the orchestration server that specifies the Jenkins credentials to use for Jenkins jobs.
9. In the Environments section, specify the URL for your development system and the candidate systems that are in your pipeline, and also specify merge targets.
   1. Specify development system information:
      1. In the Development field, enter the URL of the development system.
      2. In the Authentication profile field, press the Down Arrow key and select the authentication profile that you want to communicate from the orchestration server to the development system.
   2. Specify the URL of the candidate systems and the authentication profiles that the orchestration server uses to communicate with candidate systems. Select the authentication profile that you configured in step 4 in the Configuring candidate systems section of Installing and configuring Deployment Manager 01.01.02 and 02.01.01. Fields are displayed only for the pipeline stages that you selected in the build life cycle on the previous page.
10. Specify merge options.
    1. Do one of the following actions:
       • To merge branches into the highest existing ruleset in the application, click Highest existing ruleset.
       • To merge branches into a new ruleset, click New ruleset.
    2. Optional: In the Password field, enter the password that locks the rulesets.
11. In the Application repository section, select the development and production repositories.
    1. In the Dev repository field, press the Down Arrow key and select the repository that connects to a candidate system from the development system. The archived Product rule that contains the application in your pipeline is sent from the development system to the candidate system to which this repository connects.
    2. In the Production repository field, press the Down Arrow key and select the production repository. The archived product rule that contains the application is sent from a candidate system to the production system to which this repository connects.
12. Click Next.
13. Specify the application and the application contents that you want to build in your pipeline by completing the following steps:
    1. In the Application field, press the Down Arrow key and select your application.
    2. In the Version field, press the Down Arrow key and select the application version.
    3. In the Product rule field, press the Down Arrow key and select the product rule that defines the contents of the application.
    4. In the Version field, press the Down Arrow key and select the product rule version.
    5. Optional: Add dependent applications. For more information, see Product rules: Listing product dependencies for Pega-supplied applications.

    6. ClickAdd.

   3. Click Save.

For detailed information about modifying your pipeline, see Adding an application pipeline.

Manually starting a build

Start a build manually if you are not using branches and are working directly in rulesets.

You can also start a build manually if you do not want builds to start automatically when branches are merged. You must also clear the Trigger build on merge check box in the pipeline configuration.

If you are using branches, developers can start builds when they publish branches. For more information about publishing branches, see Publishing a branch to a repository.

1. In the Designer Studio footer, click DevOps.
2. Click the pipeline for which you want to start a build.
3. Click Start build.

Completing or rejecting a manual step in a build

If a manual step is configured for a build, the build pauses when it reaches the step, and you can either complete it or reject it. For example, if a user was assigned a task and completed it, you can complete the task to continue the build. Deployment Manager also sends you an email when a manual step is n the pipeline. You can complete or reject a step either within the pipeline or through email.

Deployment Manager also generates a manual step if schema changes are in the application package that the release manager must apply. For more information, see Schema changes in application packages.

To complete or reject a manual step within the pipeline, do the following steps:

1. In the Designer Studio footer, click DevOps.
2. Click a pipeline.
3. Right-click the manual step and select one of the following options:
   • Complete task: Resolve the task so that the build continues through the pipeline.
   • Reject task: Reject the task so that the build does not proceed.

To complete or reject a manual step from within an email, click either Accept or Reject.

Schema changes in application packages

If an application package that is to be deployed on candidate systems contains schema changes, the Pega Platform orchestration server checks the candidate system to verify that you have the required privileges to deploy the schema changes. One of the following results occurs:

• If you have the appropriate privileges, schema changes are automatically applied to the candidate system, the application package is deployed to the candidate system, and the pipeline continues.
• If you do not have the appropriate privileges, Deployment Manager generates an SQL file that lists the schema changes and sends it to your email address. It also creates a manual step and pauses the pipeline, so that you can apply the schema changes. After you complete the step, the pipeline continues. For more information about completing a step, see Completing or rejecting a manual step.

You can also configure settings to automatically deploy schema changes so that you do not have to manually apply them if you do not have privileges to do so. For more information, see Configuring settings to automatically deploy schema changes.

Configuring settings to automatically deploy schema changes

You can configure settings to automatically deploy schema changes that are in an application package that is to be deployed on candidate systems. Configure these settings so that you do not have to apply schema changes if you do not have the privileges to deploy them.

1. On each candidate system on which to deploy schema changes, in Pega Platform, set the AutoDBSchemaChanges Dynamic System Setting to true to enable schema changes at the system level:
   1. In Designer Studio, search for AutoDBSchemaChanges.
   2. On the Settings tab, in the Value field, enter true.
   3. Click Save.
2. Add the SchemaImport privilege to your access role to enable schema changes at the user level. For more information, see Specifying privileges for an Access or Role to Object rule.

These settings are applied sequentially. If the AutoDBSchemaChanges Dynamic System Setting is set to false, you cannot deploy schema changes, even if you have the SchemaImport privilege.

For more information about the database/AutoDBSchemaChanges dynamic system setting, see Importing rules and data by using a direct connection to the database.

Pausing a build

To pause a build, click the Pause button.

When you pause a build, the pipeline completes the task that it is running, and stops the build at the next step.

Performing actions on a build with errors

If a build has errors, the pipeline stops processing on it. You can do one of the following actions:

• Ignore the current step and run the next step by clicking the Start button.
• After fixing the errors, restart the build at the current step by clicking the Start button.
• Roll back to an earlier build by clicking the Roll back build button.

Viewing branch status

You can view the status of all the branches that are in your pipeline. For example, you can see whether a branch was merged in a build and when it was merged.

1. In the Designer Studio footer, click DevOps.
2. Click a pipeline.
3. Click Actions > View branches.

Viewing report build logs

View logs for a build to see the completion status of operations, for example, when a build is moved to a new stage. You can change the logging level to control which events are displayed in the log. For example, you can change logging levels of your builds from INFO to DEBUG for troubleshooting purposes. For more information, see Logging Level Settings tool.

1. In the Designer Studio footer, click DevOps.
2. Click a pipeline.
3. Click the Gear icon for the build for which you want to view the log file.
