RelOps Infrastructure-As-Code

getting started

The repo uses pre-commit (https://pre-commit.com/) to install and manage git pre-commit hooks.

os x

brew install pre-commit
brew install terraform-docs

pre-commit install

structure

We manage state per-module. This allows us to work with some isolation to avoid conflicts with other people's changes and reduces the number of objects synced during terraform apply.

creating new modules

cd terraform
./create_state.sh "descriptive_name_for_what_this_module_does"

Then follow the directions given.

Authenticating to Azure, Google Cloud, or AWS

## AWS
export AWS_ACCESS_KEY_ID=foo
export AWS_SECRET_ACCESS_KEY=bar

## GCP
export GOOGLE_CLOUD_KEYFILE_JSON=~/.config/gcloud/application_default_credentials.json

## Azure
$ az login
$ az account set --subscription "108d46d5-fe9b-4850-9a7d-8c914aa6c1f0" ## based on subscription

Updating providers

Providers should be regularly upgraded. If you get an error during a plan or apply, always try this first.

terraform init -upgrade
