Galley crashing on Brand New Installation

feitnomore · February 8, 2019, 7:07pm

I’m getting an error on Galley installing istio 1.1.0-snapshot5.

Can anyone share any light? Can it be RBAC problems? I see another error in the beggining:

Hi,

The crash itself is due to a bug that was recently fixed in the release 1.1 branch.

The underlying cause is the missing CRD

2019-02-08T19:04:52.864994Z	info	kube	zipkins.config.istio.io/v1alpha2 resource type not found

The zipkin CRD is not available. (You’d normally observe this as Galley quitting).

ed.snible · February 8, 2019, 7:35pm

I traced the code for https://github.com/istio/istio/blob/f1eab0a25dd6f37be03951698be0e84b120ec18f/galley/pkg/server/server.go#L217 and could not discover the root cause for the traceback.

The “invalid value: only ASCII characters accepted; max length must be 255 characters” message comes from go.opencensus.io/tag/validate.go and is probably caused by the previous message being longer than 255 characters (it’s 376 characters). I am not sure why istio-galley-service-account cannot set finalizers; I don’t see this message on my deployment.

kconner · February 8, 2019, 7:36pm

And the error about the ownerReference is a permissions issue, the galley cluster role needs to have the following added. I think there may already be a PR for this

apiGroups: [“extensions”]
resources: [“deployments/finalizers”]
resourceNames: [“istio-galley”]
verbs: [“update”]

kconner · February 8, 2019, 7:37pm

There wasn’t but there is now :), https://github.com/istio/istio/pull/11631/files

ayj · February 8, 2019, 7:38pm

This was fixed in master yesterday. The corresponding PR for 1.1 is https://github.com/istio/istio/pull/11631.

feitnomore · February 8, 2019, 10:05pm

@ayj will this be available on any kind of nightly build at Istio Release downloads page under 1.1.0-snapshot5?

@kconner I’ll try to add those by hand, thanks!

@ozevren where is this crd defined? I’ve applied all the crds needed. Can you point me to where it is defined or the details so I can apply it by hand? Also, the fix that you mentioned was merged in 1.1, will it be available on any snapshot Pre-Release under Istio Release downloads page?

Thanks guys, you’re relly fast!

ayj · February 11, 2019, 6:33pm

@feitnomore, this should be available in the latest daily release 1.1 build (e.g. https://gcsweb.istio.io/gcs/istio-prerelease/daily-build/release-1.1-20190211-09-16/)

feitnomore · February 12, 2019, 10:53am

Folks, what about the segmentation fault? Will it be available? I’ve got the latest version stated by @ayj but I’m still crashing:

Ok, looks like there is something else missing. I needed to apply these by hand to fix the problem:

Marcelo,

Can you give me exact repro steps? I’ve tried installing the build ayj@ at was pointing, and I didn’t hit into any crashes with a stock installation, or when I remove some of the CRDs.

ozevren · February 12, 2019, 4:43pm

Are you deleting CRDs by hand?

feitnomore · February 12, 2019, 4:43pm

cd install/kubernetes/helm/
tar -xvzf charts/istio-1.1.0.tgz
tar -xvzf charts/istio-init-1.1.0.tgz
cd /root/istio-1.1.0/

/root/helm-linux-amd64/helm template install/kubernetes/helm/istio --name istio --namespace istio-system --set tracing.enabled=true --set ingress.enabled=true --set gateways.enabled=true --set gateways.istio-ingressgateway.enabled=true --set gateways.istio-egressgateway.enabled=true --set sidecarInjectorWebhook.enabled=true --set galley.enabled=true --set mixer.enabled=true --set mixer.istio-policy.autoscaleEnabled=true --set mixer.istio-telemetry.autoscaleEnabled=true --set pilot.enabled=true --set telemetry-gateway.grafanaEnabled=true --set telemetry-gateway.prometheusEnabled=true --set grafana.enabled=true --set prometheus.enabled=true --set servicegraph.enabled=true --set tracing.ingress.enabled=true --set kiali.enabled=true --set global.proxy.privileged=true > /root/istio.yaml

for i in install/kubernetes/helm/istio-init/files/crd*yaml; do kubectl apply -f $i; done

kubectl label namespace istio-system istio-injection=disabled

After that I’ve applied istio.yaml, and saw the crash, so I’ve added the 2 CRDs by hand.

Thanks,
Marcelo

feitnomore · February 13, 2019, 12:01pm

@ozevren I’ve tried the latest build again, and those CRD were missing.

/root/helm-linux-amd64/helm template install/kubernetes/helm/istio-init/ --name istio-init --namespace istio-system > /root/istio-init.yaml
/root/helm-linux-amd64/helm template install/kubernetes/helm/istio --name istio --namespace istio-system --set tracing.enabled=true --set ingress.enabled=true --set gateways.enabled=true --set gateways.istio-ingressgateway.enabled=true --set gateways.istio-egressgateway.enabled=true --set sidecarInjectorWebhook.enabled=true --set galley.enabled=true --set mixer.enabled=true --set mixer.istio-policy.autoscaleEnabled=true --set mixer.istio-telemetry.autoscaleEnabled=true --set pilot.enabled=true --set telemetry-gateway.grafanaEnabled=true --set telemetry-gateway.prometheusEnabled=true --set grafana.enabled=true --set prometheus.enabled=true --set servicegraph.enabled=true --set tracing.ingress.enabled=true --set kiali.enabled=true --set global.proxy.privileged=true > /root/istio.yaml
kubectl apply -f /root/istio-init.yaml
kubectl apply -f /root/istio.yaml

Also, I’m getting some strange messages on the sidecarInjector:

2019-02-13T11:39:27.135724Z warn istio.io/istio/pilot/cmd/sidecar-injector/main.go:171: watch of *v1beta1.MutatingWebhookConfiguration ended with: The resourceVersion for the provided watch is too old.

My system is not getting the sidecar injected automatically even though the namespace is labeled. Not sure if this warning is causing it. I’ve got some other messages on galley as well:

It was a role problem. Sorry keep bothering you guys. Seems like the Control Panel is working fine now.
