I created cluster and node pools by terraform modules. I configured module google_container_node_pool with basic configurations is:

resource "google_container_node_pool" "cache" {
    name       = "cache"
    location   = "asia-southeast1"
    cluster    = my-cluster

    node_count = 6

    node_config {
    preemptible  = true
    machine_type = "e2-medium"
    image_type = "cos_containerd"
    disk_type = "pd-standard"
    disk_size_gb = 20
        labels = {
            role = "cache"
        }
    }
}

When I created successfully. Sometimes, node is restarted randomly. Can I check why it’s restarted?

I expect that the GKE nodes are not restart anymore
