Terraform Intro

This repo has many branches. Each branch represent an incremental terraform state. You can go through each branch an apply your changes (terraform apply) to see how that works

Usage

We are going to use AWS for this. So you need to provide your access keys as environment variables. Check env.sample to see what variables are required.

If you don't have an AWS account, you can create one (A credit card is required) at aws.amazon.com. This examples works under their free-tier plan. So it shouldn't cost you anything.

Once you have your access keys for AWS, run this:

cp env.sample .env
# replace your AWS access keys in the .env file you just created
source .env

Make sure when you end using the example, to teardown everything using terraform destroy

Installing terraform

If you are on OSX, you should have homebrew installed (if not installed it, you have been missing one of the best tools for devs in OSX)

brew install terraform

Branches

Once you reach this point, you should be able to run terraform commands without problems.

In each branch you should run first terraform plan to see the changes, and then terraform apply to apply the changes. Before continue to the other branches, if you want to apply, run terraform destroy before

Once you are done running the examples, you can run terraform destroy to teardown the resources you created
