VPC code for global, staging and production environments

About arglabs-sre-vpc

This is part of the ARGLabs project.

See more about this on Github repository and this blog post.

Why ?

Usually created by an Infrastructure team (nowadays named devops, SRE or an Infrastructure Mechanic like me), all the very basic infrastructure should be on it's own repository.

What this repo does ?

Creates the basic infrastructure like VPC, Subnets, route tables, internet gateway, nat gateways, transit gateway etc and provides all the outputs needed for other projects.

It should not be used for service or application specific resources.

DO NOT create any databases, load balancers, instances etc here.

Highlights

If done right, you don't need to change any code in this repo to add another environment or change CIDRs. Just configure it on deep-thought and use it everywhere else.

How to use it

Dependencies

You need the deep-thought applied before.

run.sh script

Usage:

# ./run.sh 
./run.sh <apply|destroy|plan> <workspace>

So, to run it on the global workspace:

 ./run.sh apply global

Expect something like this output Youtube video

How it will be used by other projects

As an external data source, like this:

data "terraform_remote_state" "vpc" {
  backend   = "s3"
  workspace = terraform.workspace
  config = {
    bucket = var.bucket
    region = var.bucket_region
    key    = "infra/sre/vpc.state"
  }
}

And then you can use any output you want:

data.terraform_remote_state.vpc.outputs.<output you want>
