Unschedulable GKE Pods with gvsior

bt flag

I created a GKE cluster that makes use of gvisor using Terraform:

resource "google_container_node_pool" "main_preemptible_nodes" {
  name    = "gke-${var.cluster_name}-preempt-nodepool"
  cluster = google_container_cluster.main_cluster.id

  node_config {
    preemptible  = true
    machine_type = "n1-standard-1"
    image_type   = "cos_containerd"

    sandbox_config {
      sandbox_type = "gvisor"
    }
}

However, this is leading to 10 uneschedulable Pods. If I e.g. check event-exporter-gke, this returns the error:

0/1 nodes are available: 1 node(s) had taint {sandbox.gke.io/runtime: gvisor}, that the pod didn't tolerate.

However since those are system Pods and gvisor is a native functionality of GKE I'm at a loss why this is happening. Any ideas?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
