I’m installing istio using istioctl, but I’ve been having timeout problems, in istioctl it shows this

✘ Istiod encountered an error: failed to wait for resource: resources not ready after 5m0s: timed out waiting for the condition

and when I see the kubectl describe I got

0/2 nodes are available: 2 Insufficient memory.

(combined from similar events): Unable to attach or mount volumes: unmounted volumes=[istiod-ca-cert], unattached volumes=[config-volume istiod-ca-cert istio-token podinfo ingressgateway-ca-certs istio-ingressgateway-service-account-token-q64xg ingressgatewaysdsudspath istio-envoy ingressgateway-certs]: timed out waiting for the condition

Hi there,

This looks like the amount fo memory istio requires is not available on your current nodes. You can see the amount of available memory for each node size here:https://www.digitalocean.com/docs/kubernetes/#allocatable-memory

I would recommend replacing your current nodes with larger ones and seeing if that allows istio to deploy.

Hope this helps!

Regards,

John
