Instances should not have public IP addresses
Default Severity: high
Explanation
Instances should not be publicly exposed to the internet
Possible Impact
Direct exposure of an instance to the public internet
Suggested Resolution
Remove public IP
Insecure Example
The following example will fail the google-compute-no-public-ip check.
resource "google_compute_instance" "bad_example" {
name = "test"
machine_type = "e2-medium"
zone = "us-central1-a"
tags = ["foo", "bar"]
boot_disk {
initialize_params {
image = "debian-cloud/debian-9"
}
}
// Local SSD disk
scratch_disk {
interface = "SCSI"
}
network_interface {
network = "default"
access_config {
// Ephemeral IP
}
}
}
Secure Example
The following example will pass the google-compute-no-public-ip check.
resource "google_compute_instance" "good_example" {
name = "test"
machine_type = "e2-medium"
zone = "us-central1-a"
tags = ["foo", "bar"]
boot_disk {
initialize_params {
image = "debian-cloud/debian-9"
}
}
// Local SSD disk
scratch_disk {
interface = "SCSI"
}
network_interface {
network = "default"
}
}
