LV-426

A host repository for experimenting with Terraform and related tools (hence the whimsical name).

Also to collect tools in relevant reference file, based on tooling from an OSX workstation (hence Brewfile, bundler etc)

To understand what this contains, also start from https://www.liatrio.com/blog/secure-aws-account-structure-with-terraform-and-terragrunt as an approach and some pre requisites. Some one beat me to this little project but I'm going to use it a a reference not a blocker to self learning http://eddwardo.github.io/terraform/cloud/iac/2019/06/24/terraform-project-structure/

Config

• AWS, ~/aws/credentials is obviously required.
• AWS policy, for the Terraform or Terragrunt admin group for managing state https://github.com/gruntwork-io/terragrunt/blob/master/docs/_docs/02_features/aws-auth.md#aws-iam-policies
• command line and credentials, https://blog.gruntwork.io/authenticating-to-aws-with-the-credentials-file-d16c0fbcbf9e
• gitignore, https://github.com/github/gitignore/blob/master/Terraform.gitignore
• https://www.terraform.io/docs/commands/cli-config.html#credentials
• https://github.com/tonedefdev/terracreds

Interfaces

• AWS, https://console.aws.amazon.com/ obv. you need to know where the AWS console is so you can do the initial config and or setup.
• Azure, https://portal.azure.com, cos why use one cloud when you can hybridize (is that even a word)
• GCP, https://console.cloud.google.com/

Learning

https://learn.hashicorp.com/terraform?utm_source=terraform_io all three platforms, and more, plus links to hashicorps public code examples to support the tutorials.

Azures platform best practices https://registry.terraform.io/modules/aztfmod/caf/azurerm/latest

a series of modules for gcp start with the bootstrap one https://github.com/terraform-google-modules all available on the regsitry too.
