When Things Go Wrong

A bad upgrade happens to everyone. Because Helm keeps history, you can undo it with helm rollback instead of debugging under pressure. 🛟

Roll Back One Step

Called with just the release name, helm rollback returns to the immediately previous revision. The fastest way to undo a fresh mistake.

Target a Specific Revision

You can also name the exact revision to restore. Read it from helm history, then pass that number.

Rollback Is Itself a Revision

A rollback does not erase history. It creates a brand-new revision whose contents match the target you chose. History only grows.

Restores Values Too

Rollback restores the chart and the values from the target revision together, so the release returns to that exact configuration.

Wait for It to Settle

Add --wait so Helm blocks until the restored pods are ready, confirming the rollback truly recovered the service. ✅

Preview the Rollback

Want to see what a rollback would produce first? Add --dry-run to render it without changing the live release.

helm rollback my-app 3 --dry-run

Roll Back Hooks Too

By default rollback skips hooks. Add --no-hooks to be explicit, or omit it to let any rollback hooks run as designed.

helm rollback my-app 3 --no-hooks

Confirm the New State

After rolling back, run helm status or helm history again to confirm the deployed revision is the one you expected.

helm status my-app

Atomic Already Rolls Back

If your failed upgrade used --atomic, Helm already rolled back for you. Manual rollback is for problems found after the fact.

History Must Exist

Rollback needs a stored revision to return to. If history was purged, there is nothing to restore, so history retention is your safety net.

Quick Check

Your release is at revision 6, all good. You run helm rollback my-app 4. What happens to the revision count?

Recap

You can now recover fast with helm rollback: undo one step or target a revision, each rollback a new revision restoring its chart and values. Pair it with history and --atomic. 🚀
