How do you handle rollbacks in Jenkins pipelines in case of failed deployments? Could you share a Jenkinsfile with rollback logic for a safer deployment?

Here, you’re asked to detail strategies for rollback automation in Jenkins to ensure smooth recovery when deployments fail. A Jenkinsfile example with rollback logic for safely reverting to a previous version of the application should be provided. Discuss key aspects like detecting failures, managing rollback triggers, and ensuring minimal impact on users.

To manage rollbacks in Jenkins pipelines for deployments that failed, logic should be applied to validate the success of every deployment. In the event of a failed deployment, the pipeline is automatically triggered into a rollback of the previous stable version.

Rollback Strategy
Deploy New Version: This will deploy the newest version of the application.
Verify Deployment: Run the deployment. Report if it fails, which would trigger a rollback.
Roll back to previous version: revert to last successful deployment.

Sample Jenkinsfile with Rollback Logic

Explanation
Deploy the New Version: It deploys the latest version with rollback logic in case of errors.
Test deployment: It tests the deployment; while testing, if there is a failure in a test, it will roll back to the previous version.
This configuration offers a roll-back mechanism that is safe. It will lead to stability due to rolling back at the point of failure to a known good state.
