02/06/2023, 10:53 AMHi, I am facing to an issue to deploy Signoz with Helm on my GKE autopilot mode.
Copy code
Error: INSTALLATION FAILED: admission webhook "<http://gkepolicy.common-webhooks.networking.gke.io|gkepolicy.common-webhooks.networking.gke.io>" denied the request: GKE Warden rejected the request because it violates one or more policies: {"[denied by autogke-no-host-port]":["container my-release-k8s-infra-otel-agent specifies a host port; disallowed in Autopilot. Requested by user: 'xxx@xxxx.xx', groups: 'system:authenticated'."],"[denied by autogke-no-write-mode-hostpath]":["hostPath volume varlibdockercontainers used in container my-release-k8s-infra-otel-agent uses path /var/lib/docker/containers which is not allowed in Autopilot. Allowed path prefixes for hostPath volumes are: [/var/log/].s

02/06/2023, 12:56 PMHi @Pierre Filliolaud, I don't think log collection would be possible in OtelCollector at the moment for GKE autopilot.
You will need to disable the log collection. You can do that by including the below in `override-values.yaml`:
Copy code
k8s-infra:
presets:
logsCollection:
enabled: falseYou might also have to switch to readonly kubelet endpoint:
Copy code
k8s-infra:
presets:
kubeletMetrics:
authType: none
endpoint: ${K8S_NODE_NAME}:10255p

02/06/2023, 3:09 PMThank you @Prashant Shahi I am going to test
I set the override-values.yaml with
Copy code
global:
storageClass: gce-resizable
clickhouse:
cloud: gcp
installCustomStorageClass: true
k8s-infra:
presets:
logsCollection:
enabled: false
kubeletMetrics:
authType: none
endpoint: ${K8S_NODE_NAME}:10255and I am still getting the error
Copy code

02/07/2023, 5:58 AM@Pierre Filliolaud I see that Autopilot has some security limitations which is causing this. Unfortunately, it will require some changes and experiments from our side to confirm that it works GKE Autopilot.
Can you create an issue in SigNoz charts repo for this?
I will discuss with our team and see if this can be prioritised.
