Notes on Istio 1.4.7 to 1.5.4 upgrade via HELM

Upgrading to 1.5.4 via Helm

This is the rough outline of how we successfully did an in-place control + data plane upgrade from Istio 1.4.7 -> 1.5.4 via the official Helm charts.

Upgrade was

  • applied via scripting/automation
  • on a mesh using
    • mTLS
    • Istio RBAC via AuthorizationPolicy
  • telemetry v1

Notes on Catalina upgrade

MacOS Catalina Upgrade

On a MacBook Pro (Retina, 15-Inch, Mid 2015, from latest Mojave)

Things I noticed

  • Have to re-approve notifications from many apps via popups
  • On initial boot Docker didn't automatically start, but seems fine after first manually starting and subsequent reboots
  • A few things appeared in ~/Desktop/Relocated Items but nothing important; removed them.

May require upgrades for patches/compatibility
