How do I get it?

Auth with Google

1. Clone this repo locally, and create a Project on Google Console
2. Download JSON credentials from your service account. See here.
3. Add the json file as creds.json in root folder of this repo, and copy terraform.tfvars.example to terraform.tfvars
4. Create a ssh key pair using: ssh-keygen
5. You can find the location of your public key from the output of ssh-keygen. See Line 7 in the output like in this image:
6. Update the values and add your public key to the .tfvars file

Terraform Apply

Do terraform apply

Logging in thru SSH

1. Terraform would output the external_ip of the instance on successful apply.
