INTRODUCTION
The purpose of this article is to show a full Google Cloud Platform (GCP) environment built using Terraform automation. I’ll walk through the setup process to get Google Cloud Platform and Terraform.
Downloading and configuring Google Cloud SDK
Now that we have Terraform installed, we need to set up the command line utility to interact with our services on Google Cloud Platform. This will allow us to authenticate to our account on Google Cloud Platform and subsequently use Terraform to manage infrastructure.
Configuring our Service Account on Google Cloud Platform
Next, I will create a project, set up a service account and set the correct permissions to manage the project’s resources.
TERRAFORM PROJECT FILE STRUCTURE
Terraform elaborates all the files inside the working directory so it does not matter if everything is contained in a single file or divided into many, although it is convenient to organize the resources in logical groups and split them into different files. Let’s look at how we can do this effectively:
Samples and ideas to get started with GCP and Infrastructure as Code
R ecently I’ve been working a lot with the Google Cloud Platform, which I love. I’ve been building (and destroying!) large amounts of cloud infrastructure working on both fun and serious projects, and I’ve been using Hashicorp’s Terraform to help me do this.
Terraform Backends
Terraform needs somewhere to store the state file that it uses to manage everything. By default it will store this locally to the configuration files being used, which is fine in development circumstances, but for anything more it isn’t a suitable option.
Service Accounts and IAM
Once we start working with resources in GCP, we should think about how we secure and provide access them. We can control how our code access resources by creating Service Accounts and associated Keys, and using IAM to bind the Service Accounts to the resources with only the permissions they need (the least privilege principle).
Building a GKE Cluster and working with it
I work a lot with Google Kubernetes Engine (GKE), Google’s managed Kubernetes offering in GCP. One thing I find very useful with Terraform is that I can combine providers; I can use the GCP provider to provision my clusters, and in the same Terraform configuration use the Kubernetes provider to bootstrap and configure the cluster.
In Summary
Infrastructure as Code is a paradigm that has massive benefits, and is seeing huge growth right now. Terraform is a really great tool for reaping these benefits on projects large and small.
Creating a GCP Project with Terraform
Like most jobs today, mine requires me to automate as much of it as possible. One of the things that seemed like an easy goal was to auto the creation of a GCP Project using a tool. We used to use Google Deployment Manager, but soon found it was more of a pain than we wanted to keep up to date.
Project Layout
When creating this I laid out the files in easy to use sections. I also made sure to use the depends_on line a lot so I could ensue that everything was working in the order I wanted
Project Files
Below I will break down each file and what iot is used for as well as the code inside of it
Running the terraform script
Running the script is pretty easy. The first step is making sure you have terraform installed by going to their website. Once you have this installed and all the scripts are in the same directory, you can run some simple commands.
How to use GCP Secret Manager to Manage your Secrets using Terraform
You are going to start building your first application in GCP (Google Cloud Platform) and the question popup into your mind: How am I going to manage my credentials and secrets?
2. Enabling Secret Manager API (optional)
Before we can use the Secret Manager in our Terraform code, we will need to enable the Secret Manager API in our project. This step is mandatory.
3. Setting up Service Account Permissions
We need to update our Service Account with extra permissions. We open the GCP Portal and go to IAM & Admin and select IAM.
4. Creating the Provider file
Providers are used in Terraform to interact with Providers using API calls.
5. Creating the Secrets
In this section, we are going to create secrets in the Secret Manager.
5.1. Creating the Secrets with Automatic Replication
In the example below, we are going to create one secret to store the admin password, and we will allow GCP to choose the best location to replicate our secret.
5.2. Creating the Secrets with User-Managed Replication
In the example below, we are going to create one secret to store the admin password, and because our services are located in Europe, we will tell GCP to use the two defined European locations to replicate our secret.
