Description
Containers will be able to enumerate and interact with host's processes. This breaks container security boundary.
How to fix?
Remove hostPID attribute, or set value to false.
Remove host_pid attribute, or set value to false.
Example Configuration
resource "kubernetes_pod" "allowed" {
metadata {
name = "terraform-example-607-1"
}
spec {
host_pid = false
container {
image = "nginx:1.7.9"
name = "example"
env {
name = "environment"
value = "test"
}
port {
container_port = 8080
}
liveness_probe {
http_get {
path = "/nginx_status"
port = 80
http_header {
name = "X-Custom-Header"
value = "Awesome"
}
}
initial_delay_seconds = 3
period_seconds = 3
}
}
dns_config {
nameservers = ["1.1.1.1", "8.8.8.8", "9.9.9.9"]
searches = ["example.com"]
option {
name = "ndots"
value = 1
}
option {
