Apigee Terraform Modules

This repository provides end-to-end sample modules and reusable terraform modules for Apigee.

Prerequisites

  • terraform cli on your PATH in version >= 1.4 (or according to the version constraint in the respective module).

End-To-End Samples

Sample modules are intended to demonstrate the most common network topologies for Apigee. The sample modules don't make any assumptions about pre-exsting topologies and create all the required resources from scratch. They can be used as a starting point for your own projects or be edited to work with your existing resources (e.g to reference an existing VPC instead of creating a separate one).

  • X Basic for a basic Apigee X setup with the raw instance endpoints exposed as internal IP addresses.
  • X with external L7 LB for an Apigee X setup that is exposed via a global external L7 load balancer.
  • X with external L7 LB and northbound PSC for an Apigee X setup that uses a global external L7 load balancer and a Private Service Connect (PSC) Network Endpoint Group (NEG) to connect to an Apigee instance's service attachment.
  • X with external L7 LB, MIG and northbound PSC for an Apigee X setup that uses a global external L7 load balancer-->Managed Instance Group-->Private Service Connect (PSC) Endpoint to connect to an Apigee instance's service attachment to leverage active health check with PSC.
  • X with southbound PSC for an Apigee X setup that uses Private Service Connect (PSC) to connect to a backend service in another VPC.
  • X with internal L4 LB and mTLS for a basic Apigee X setup plus exposure via regional L4 load balancer and envoy proxy to terminate mTLS.
  • X with external L4 LB and mTLS for a basic Apigee X setup plus exposure via global external L4 load balancer and envoy proxy to terminate mTLS.
  • X with network appliance for transitive peering for an Apigee X organization that is peered to a network is transitively peered to another VPC that contains the backend. To deploy the sample, first create a copy of the example variables and edit according to your requirements.
  • X with DNS peering for a basic Apigee X setup with DNS peering with a private DNS Zone containing records for Apigee and an example backend.
  • X with controlled internet egress for a basic Apigee X setup with the runtime's internet egress routed via a firewall appliance in the customer's VPC.
  • X with Shared VPC for an Apigee X setup in a Shared VPC that is exposed via a global external L7 load balancer.
  • X with Multi Region for an Apigee X setup in a Shared VPC exposed in multiple GCP Regions via a global L7 load balancer. Note that the sample uses an EVAL Apigee X Organization and hence a single Apigee X Instance only. In case you have a PROD Apigee X Organization then you will be able to easily extend the sample accordingly.
  • X with IaC Automation Pipeline for an IaC Automation Pipeline Apigee X setup in a Shared VPC exposed in multiple GCP Regions via a global L7 load balancer. Note that the sample uses an EVAL Apigee X Organization and hence a single Apigee X Instance only. In case you have a PROD Apigee X Organization then you will be able to easily extend the sample accordingly.
  • X with Non VPC Peering with external L7 LB and northbound PSC for a basic Apigee X setup without VPC Peering requirements and expose northbound via global external L7 load balancer and a Private Service Connect (PSC) Network Endpoint Group (NEG) to connect to an Apigee instance's service attachment.

Reusable Modules

The following modules can be used either as part of the end-to-end samples above or as part of your own scripting:

  • Apigee X Core Configures a complete Apigee X organization with multiple instances, environment groups, and environments.
  • Apigee X Bridge MIG Configures a managed instance group of network bridge GCE instances (VMs) that can be used as a load balancer backend and forward traffic to the internal Apigee X endpoint.
  • Apigee X mTLS MIG Configures a managed instance group of Envoy proxies that can be used to terminate mutual TLS and forward traffic to the internal Apigee X endpoint.
  • L7 external LB for MIG Configures an external HTTPS Cloud Load Balancer that fronts managed instance groups.
  • L4 external LB for MIG Configures an external TCP Proxy that fronts managed instance groups.
  • Routing Appliance Configures a routing appliance and custom routes to overcome transitive peering problems.
  • Northbound PSC Backend Private Service Connect (PSC) Network Endpoint Group (NEG) backend with an HTTPS external load balancer.
  • Southbound PSC Backend Private Service Connect (PSC) service attachment and Apigee endpoint attachment.
  • Development Backend Configures an example HTTP backend and an internal load balancer.
  • NIP.io Development Hostname Configures an external IP address and hostname based on the IP and the nip.io mechanism as well as a Google-managed SSL certificate.
