Demystifying Google Cloud Networking for Cloud SQL Setup with Infrastructure as Code (IaC) —Part I
Setting up , managing infrastructure and creating necessary cloud networking components required for Google Cloud SQL instances can be a complex task, especially when you need to restrict the access of Cloud SQL instance via its private IP addresses. But what if there was a way to simplify this entire process from enabling API’s, creating VPC, IAM policies, firewall rules, configuring service networking etc and making it more accessible to users, even those with limited experience in Google Cloud?
Our comprehensive cloudsql easy networking terraform module repository has been designed to streamline the deployment and management of Google Cloud SQL instances with private IP. In this blog post, we’ll introduce you to this powerful repository and explain how it can help you set up Cloud SQL instances with ease.
The Problem: Complex Networking for Cloud SQL with private IP
Configuring Google Cloud networking for Cloud SQL instances can be challenging, especially for users who are not familiar with the intricacies of VPCs, subnets, service networking and firewall rules. To simplify this process, we’ve bundled Terraform modules into a single repository to handle the networking configuration seamlessly.
The Solution: Terraform Modules for Google Cloud SQL Easy Networking
Our repository contains easy-to-use bundled Terraform modules that set up all the prerequisites required for consuming private Cloud SQL instance deployed in a Google Cloud Platform (GCP) project. These modules abstract away the complexity, making it easy for users like database administrators , application engineers to configure Cloud SQL with the necessary cloud networking components.
Example Use Case
To illustrate the simplification of cloud networking provided by our Terraform module repository, let’s consider a common use case.
Imagine you are a database administrator responsible for setting up a new Cloud SQL instance for a production application. You need to configure the instance to use a private IP so that it is only accessible from within your VPC network or the on-premise network.
Using the Terraform modules in this repository, you can easily configure the Cloud SQL instance and all the necessary network resources with just a few lines of configuration. The steps typically involve:
- Cloning the git repository containing the end to end examples.
- Create a new Terraform configuration file and define the variables for your GCP Project, Cloud SQL instance and network configuration as described in the readme file.
- Initialize Terraform and download the necessary providers and modules.
- Plan and apply the Terraform configuration.
Once the Terraform configuration has been applied, your Cloud SQL instance will be up and running with a private IP. You will then be able to connect to the instance from within your VPC network using the private IP address.
Supported Usage Scenarios
To further assist you in using our easy networking cloud sql modules, we’ve included multiple examples in the examples folder of the github code repository.
These examples cover different scenarios, complete with implementation guides and architecture designs. Here is a short description about them that you can explore:
- Host Service Project Scenario: This example guides users through enabling GCP API’s, setting up service networking, configuring host and a service project, creating a Cloud SQL instance, and connecting it to a VM instance using private IP addresses of the Cloud SQL instance. The host project contains the VPC, subnets, and firewall rules. Following is the architecture diagram that describes the complete flow being handled by this example.
2. VPC across VPN Tunnel Scenario: In this example, we walk you through creating a highly available (HA) VPN connection between a user project and a host project with a service project attached. This solution establishes a Cloud SQL connection using the private IP address of the Cloud SQL instance created in the service project and a VM instance created in the user project. The host project contains the VPC, subnets and firewall rules. Following is the architecture diagram that describes the complete flow being handled by this example.
In summary, our cloud sql easy networking terraform module repository is your go-to resource for simplifying Google Cloud SQL instance deployment and management, especially when it comes to networking configurations. Whether you’re a seasoned database administrator or a developer looking to streamline your Cloud SQL setup, our repository has you covered.
If you’re ready to supercharge your Google Cloud SQL configuration, explore our repository and discover how Terraform modules can make your life easier. Say goodbye to complex networking configurations and hello to simplified Cloud SQL deployment.
