This terraform is intended to quickly prepare VM instance on GCP along with necessary configuration to run eve-ng. It creates image based on ubuntu with enabled virtualization, vpc, private subnet, firewall rules and VM instance.

Prerequisites

1. Install terraform -> follow official guide.
2. Install gcloud -> follow official guide.
3. Create GCP project, enable Compute Engine API.
4. Initialize gcloud -> execute gcloud init and follow wizzard, choose created project.
5. Create and download service account key -> follow guide and export downloaded key's path to GOOGLE_CLOUD_KEYFILE_JSON.
6. Find project id -> execute gcloud projects list, copy id of a created project.
7. Initialize terraform -> execute terraform init.

Provision infrastructure:

1. Plan terraform changes:

   terraform plan -var "project=<copied-project-id>"

2. Apply terraform changes:

   terraform apply -var "project=<copied-project-id>"

Deprovision infrastructure:

1. Destroy terraform changes:

   terraform apply -destroy -var "project=<copied-project-id>"

Notes

Installation proccess

Due to imperative nature of eve-ng installation proces, this terraform only prepares a VM for eve-ng installation. Later instalation steps can be found in a cookbook, section 3.4.4. Section 3.4.6 might be ommited as firewall rules have been already configured by this terraform.

Resources and costs

GCP bills for running VM instances and persistent storage. It is highly recommended to stop eve-ng instance when it's not in use. It can be quickly done by executing gcloud compute instances stop <instance-name>. By default, machine type configured in this terraform is set to n2-standard-2. This is rather minimal setup, yet it can be overriden by machine_type variable.
