I was trying to upgrade my current Istio installation from 1.4.3 to 1.6.5. I did as it’s described in v1.6 doc.
I got an error while executing
istioctl install --set revision=canary, see below:
▶ ./istioctl install --set revision=canary ✔ Istio core installed ✔ Istiod installed ✘ Addons encountered an error: failed to wait for resource: resources not ready after 5m0s: timed out waiting for the condition Deployment/istio-system/prometheus ✘ Ingress gateways encountered an error: failed to wait for resource: resources not ready after 5m0s: timed out waiting for the condition Deployment/istio-system/istio-ingressgateway - Pruning removed resources Error: failed to apply manifests: errors occurred during operation
There were 2 pods were added,
So, I tried to reverted back by re-running
istioclt apply -f FILE.yaml and also
kubectl rollout restart deployment.
All istio pods were terminated and re-created, including
How can I revert back to version 1.4.3 and how can I remove
prometheus resources (pods, svc, rs, deployments)?
