Upgrading istio on gke

taegyunkim · May 13, 2020, 6:00am

I wanted to try deploying WASM extension on gke using this demo application

Realized that GKE doesn’t support istio 1.5.x yet https://cloud.google.com/istio/docs/istio-on-gke/versions

So I just tried
$> istioctl upgrade --force
and got ‘installation complete’ message as in here

istioctl upgrade --force

Control Plane - citadel pod - istio-citadel-bc69f964d-5gq5d - version: 1.4.6
Control Plane - galley pod - istio-galley-57d74676f6-xkqhb - version: 1.4.6
Control Plane - ingressgateway pod - istio-ingressgateway-6855988795-9dlnk - version: 1.4.6
Control Plane - pilot pod - istio-pilot-b6866b4d9-qqzjc - version: 1.4.6
Control Plane - policy pod - istio-policy-698f74bc98-clj7d - version: 1.4.6
Control Plane - sidecar-injector pod - istio-sidecar-injector-d5485f495-xvt2c - version: 1.4.6
Control Plane - telemetry pod - istio-telemetry-58769bf595-htrtf - version: 1.4.6

Upgrade version check passed: 1.4.6 -> 1.5.2.

then restarted the pods as suggested

To verify update, I ran $> istioctl version and got this
client version: 1.5.2
citadel version: 1.4.6-gke.0
galley version: 1.4.6-gke.0
ingressgateway version: 1.4.6-gke.0
pilot version: 1.4.6-gke.0
policy version: 1.4.6-gke.0
sidecar-injector version: 1.4.6-gke.0
telemetry version: 1.4.6-gke.0
pilot version: 1.5.2
data plane version: 1.4.6-gke.0 (18 proxies)

It doesn’t look like it’s updated. Is there a way to do this properly?
