How to enable Allow HTTP traffic / Allow HTTP traffic on Google Compute Engine with terraform

Question

Is there any other way to enable these rules directly with terraform without having to create a separate firewall rule in GCP and then attaching tags to compute engine

Currently I am doing this way

resource "google_compute_firewall" "allow_http" {
  name    = "allow-http-rule"
  network = "default"
  allow {
    ports    = ["80"]
    protocol = "tcp"
  }
  target_tags = ["allow-http"]
  priority    = 1000

}

and then use this tag in

resource "google_compute_instance" "app" {
  ...
  tags = ["allow-http"]
}

Answer 1

The Argument Reference mentions the option tags. You can use it as follows:

...
  tags = ["http-server","https-server"]
...

In this same way, you can edit these values using: gcloud compute instances add-tags as follows:

To add the tags to an existing VM instance, use this gcloud command:

gcloud compute instances add-tags [YOUR_INSTANCE_NAME] --tags http-server,https-server

To add the tags at the time of the instance creation, include that flag in your statement:

gcloud compute instances create [YOUR_INSTANCE_NAME] --tags http-server,https-server

Answer 2

We need to have both firewall rules (http, https)in our network. we can able to see that tags in default network.

it works for me

resource "google_compute_instance" "name" {
 ....
tags = ["http-server","https-server"]
 ....
}
