Post deployment rollback

info

Currently, this feature is behind the feature flag POST_PROD_ROLLBACK. Contact Harness Support to enable the feature.

Post deployment rollback initiates a rollback of your most recent successful deployment. This allows rapid, predictable recovery from a deployment that succeeded on technical criteria, but that you want to roll back for other reasons.

Important notes​

  • Post deployment rollback is currently supported for the following deployment types only:

    • Kubernetes

    • AWS Auto Scale Group (ASG)

    • Tanzu Application Services (TAS)

    • Amazon Elastic Container Service (ECS)

      Harness anticipates expanding this feature to other deployment types in the future.

  • You can rollback successful pipelines only. The rollback option is not available for failed pipelines.

  • Only the rollback steps that are part of the stage can be used during rollback.

  • You cannot roll back the same pipeline multiple times. You can perform rollback if the pipeline is executed again.

  • If the pipeline configuration has changed between executions, the previous execution YAML is used as reference to roll back.

  • Rollback steps can use expressions that refer to steps executed during the previous pipeline execution. The expressions are automatically resolved with values from the original execution.

  • The stages should roll back in reverse order when deployment rollback is triggered.

Roll back deployments​

For post deployment rollback, Harness assumes that you have created a pipeline with multiple deployments so that the rollback steps can roll the pipeline back to the last successful deployment.

For more details on creating a pipeline, go to Create your first CD pipeline.

  1. Open your services dashboard.

  2. In Summary, in the Environments & Groups panel, select the deployment you want to roll back, and then select the instances link.

    Here's an example pipeline where the artifacts, library/nginx:stable-perl is deployed first, and library/nginx:stable-bullseye-perl is deployed next.

  3. In Instance Details, select Rollback.

    Here, you're rolling back the deployed instance with the artifact library/nginx:stable-bullseye-perl to the previously deployed instance with artifact library/nginx:stable-perl.

  4. In the Rollback infrastructure dialog, select Confirm.

    The pipeline execution for rollback stage appears in a new tab.

    Once the rollback is complete, your deployed instances will return to the state they were in before the most recent deployment.
