Description
Access to a Docker host from the container can lead to container escape attacks and privilege escalation on the host.
How to fix?
Remove hostPath volume mount.
Remove host_path.path from the spec.volume attribute.
Example Configuration
resource "kubernetes_pod" "allowed" {
metadata {
name = "example-623a1"
}
spec {
volume {
name = "example-623a1"
}
container {
image = "nginx:1.7.9"
name = "example"
}
dns_config {
nameservers = ["1.1.1.1", "8.8.8.8", "9.9.9.9"]
searches = ["example.com"]
}
dns_policy = "None"
}
}
