README

This is a work in progress. This code does not represent production infrastructure yet. For the canonical source of GOV.UK’s infrastructure, see alphagov/govuk-aws and alphagov/govuk-puppet repos.

What’s in this repo

The govuk-infrastructure repo contains Terraform modules for turning up an EKS cluster for GOV.UK.

Helm charts have moved to alphagov/govuk-helm-charts.

Usage

To install the currently used version of Terraform:

brew install tfenv
cd terraform/
tfenv install
