Kubernetes rollbacks also have a mechanism to keep previous versions of deployments. Even if a new deployment doesn't pass through health checks, you could very easily roll back to a previous version using the kubectl rollout undo command. This is how you would do it.

By defining readinessProbes and livenessProbes in your deployment YAML, you can prevent unready deployments from impacting the live service and ensure they can be rolled back quickly if necessary.
