Pave GCP for Concourse

Description

This repository is derived from https://github.com/pivotal/paving

It's designed to create the infrastructure necessary to deploy Concourse for platform automation.

• Only the GCP IaaS is concerned.
• terraform resources needed for Concourse have been added
• resources not necessary for Concourse have been removed

Assumptions

• This repository was cloned to your workspace
• terraform v0.12 is installed
• A service account key with permissions necessary to create resources in your gcp project

Steps

1. In GCP create a DNS zone for your subdomain

2. Make a copy of terraform.tfvars.example; name the copy terraform.tfvars

3. Edit terraform.tfvars and fill in these fields

   • an environment name of your choosing
   • the target GCP project id
   • the name of the hosted zone created above
   • and a JSON-encoded GCP service account key

4. Initialize terraform

   terraform init

5. Run terraform refresh to update the state with what currently exists in GCP

   terraform refresh -var-file terraform.tfvars

6. Run terraform plan to see what changes will be made in the infrastructure

   terraform plan -out terraform.tfplan -var-file terraform.tfvars

7. Run terraform apply to create the resources in the IaaS

   terraform apply -parallelism=5 terraform.tfplan
