    helm upgrade rollback

    When we upgrade an application using helm it can always go something wrong so instead of upgrading to another version or uninstall / install the application, we can rollback to a previous version that we know it is working

    Previously we already talked about the helm history command

    $ helm history pet2cattle REVISION UPDATED STATUS CHART APP VERSION DESCRIPTION  60 Wed Dec 30 16:17:58 2020 superseded pet2cattle-1.7 2.8 Upgrade complete 61 Fri Jan 1 21:45:07 2021 superseded pet2cattle-2 3 Upgrade complete 62 Sat Jan 2 11:57:26 2021 superseded pet2cattle-2 3.1 Upgrade complete 63 Sat Jan 2 22:09:24 2021 superseded pet2cattle-2 3.2 Upgrade complete 64 Mon Jan 4 09:33:53 2021 superseded pet2cattle-2 3.3 Upgrade complete 65 Tue Jan 5 07:57:53 2021 superseded pet2cattle-2 3.4 Upgrade complete 66 Wed Jan 6 15:25:30 2021 superseded pet2cattle-2 3.5 Upgrade complete 67 Thu Jan 7 09:10:07 2021 superseded pet2cattle-2 3.6 Upgrade complete 68 Fri Jan 8 08:17:56 2021 superseded pet2cattle-2 3.7 Upgrade complete 69 Sat Jan 9 19:23:25 2021 deployed pet2cattle-2 3.8 Upgrade complete
