Document how to recover from Error: another operation (install/upgrade/rollback) is in progress

[krassowski]

If the helm chart upgrade is interrupted the Error: another operation (install/upgrade/rollback) is in progress operation persists preventing further deployment. It should be possible to recover from this by executing a helm rollback command. I do not know how to execute this command

In a local test deployment what worked for me was running:

kubectl get secret -A | grep jupyterhub

This returns a list like

dev              nebari-jupyterhub-sftp                                              Opaque                                2      8d
dev              nebari-jupyterhub-ssh                                               Opaque                                1      8d
dev              sh.helm.release.v1.jupyterhub-dev.v1                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v2                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v3                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v4                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v5                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v6                                helm.sh/release.v1                    1      7d
dev              sh.helm.release.v1.jupyterhub-dev.v7                                helm.sh/release.v1                    1      1d

then find the the one with the greatest version (in this example sh.helm.release.v1.jupyterhub-dev.v7), then running:

kubectl delete secret sh.helm.release.v1.jupyterhub-dev.v7
