Managing infrastructure as code with Terraform, Cloud Build, and GitOps

This is the repo for the Managing infrastructure as code with Terraform, Cloud Build, and GitOps tutorial. This tutorial explains how to manage infrastructure as code with Terraform and Cloud Build using the popular GitOps methodology.

Configuring your dev environment

Just for demostration, this step will:

1. Configure an apache2 http server on network 'dev' and subnet 'dev-subnet-01'
2. Open port 80 on firewall for this http server

cd ../environments/dev
terraform init
terraform plan
terraform apply
terraform destroy

Promoting your environment to production

Once you have tested your app (in this example an apache2 http server), you can promote your configuration to prodution. This step will:

1. Configure an apache2 http server on network 'prod' and subnet 'prod-subnet-01'
2. Open port 80 on firewall for this http server

cd ../prod
terraform init
terraform plan
terraform apply
terraform destroy

Suggested Pre-Requsites

• Create a demo project so you can easily destroy it later!
• Clone github repo (https://github.com/jjenkins70/solutions-terraform-cloudbuild-gitops)
• Configure Demo Project
  • PROJECT_ID=$(gcloud config get-value project)
  • gcloud services enable cloudbuild.googleapis.com compute.googleapis.com git commands for CLI ease of use

git checkout -b new_branch (off of dev)
git remote add upstream https://github.com/jjenkins70/solutions-terraform-cloudbuild-gitops
git push -u origin new_branch

After Demo

• Reset unique project ID to PROJECT_ID and push to git

cd ~/solutions-terraform-cloudbuild-gitops
sed -i s/$PROJECT_ID/PROJECT_ID/g environments/*/terraform.tfvars
sed -i s/$PROJECT_ID/PROJECT_ID/g environments/*/backend.tf

• Update modules/firewall/http-server to http-server2 Updated for live demo
