Incident postmortem
Bitnami update breaks post v0.4.0 releases
On June 2, 2022, GitHub user @peytondmurray reported issue 1306, stating that he was unable to deploy QHub using either the latest release v0.4.1 or installing qhub from main. As verified by @peytondmurray and others, during your first qhub deploy, the deployment halts and complains about two invalid Helm charts missing from the bitnami index.yaml.
Bitnami's decision to update how long they keep old Helm charts in their index for has essentially broken all post v0.4.0 versions of QHub.
This is a severe bug that will affect any new user who tries to install and deploy QHub with any version less than v0.4.2 and greater than or equal to v0.4.0.
Given the impact and severity of this bug, the team has decided to quickly cut a hotfix.
AWS deployment failing due to old auto-scaler helm chart
On May 27, 2022, GitHub user @tylerpotts reported issue 1302, stating that he was unable to deploy QHub using the latest release v0.4.1 (or installing qhub from main). As described in the original issue, the deployment failed complaining about the deprecated v1beta Kubernetes API. This led to the discovery that we were using an outdated cluster_autoscaler helm chart.
The solution is to update from v1beta to v1 Kubernetes API for the appropriate resources and update the reference to the cluster_autoscaler helm chart.
Given the impact and severity of this bug, the team has decided to quickly cut a hotfix.
