Description

kubelet_config in azurerm_kubernetes_cluster.default_node_pool and azurerm_kubernetes_cluster_node_pool does not allow setting the kubelet configuration runtimeRequestTimeout. This can lead to problems e.g. when using large docker images.

runtimeRequestTimeout is the timeout for all runtime requests except long running requests - pull, logs, exec and attach. Default: "2m"

(from https://kubernetes.io/docs/reference/config-api/kubelet-config.v1beta1/#kubelet-config-k8s-io-v1beta1-KubeletConfiguration).

is there any workaround how to increase runtimeRequestTimeout?

[Johannesm299]

@stephybun "sdk/not-yet-supported" because the azure rest api does not support "runtimeRequestTimeout" in its kubelet config for agent pool creation?

[stephybun]

@Johannesm299 that is correct. If it isn't available in the AKS API then it isn't something that we can support.

I would suggest heading over to the AKS repo and raising a feature request there so the service team can take a look at adding it.

Thanks for taking the time to open this issue. It looks like the behavior you requested is not supported by the underlying AKS API so I am going to close it for now. If you create a request on AKS repo, feel free to add the link here. When it gets added, we can reopen this request or you can create a new one.
