Docker via Terraform on GCP

This project will leverage GCP to quickly land a google compute instance with docker installed. Firewall rules are strict and disallow inbound ports including SSH. To deploy scripts without SSH I used templates and GCP's metadata startup script. This instance should be always free and a new account comes with $300 usable during the first 12 months.

Prerequisites

Install Terraform and Git. I suggest using chocolatey for Windows or homebrew for Mac.

Getting Started

Create Google Cloud Platform account
Take note of your generated project name and ID (or create your own project name)
Create a service account and download your subsequent JSON key

Installation

Clone Repo and run terraform init

git clone https://github.com/terraformed/terraform-docker-gcp.git
cd ./terraform-docker-gcp
terraform init

Copy downloaded json credential file to this project location and rename it to gcp-key.json
Modify gcp_project value in vars.tf to match the your project ID in google cloud

Execute Terraform plan and apply

terraform plan
terraform apply -auto-approve

Log into GCP console and confirm your docker container(s) is running
```
sudo docker container ls #on google cloud vm instance
```

By default I included a postgres db but you can put specify containers in docker-compose-build.tpl which becomes docker-compose.yml on the host.

Optional

To enable 80 and 443 uncomment the 'tags' line in main.tf
