Exercise3: Make and Try continuous deployment and Infrastructure as code

Goal

Understand the concept of Continuous Deployment and Infrastructure as code(Terraform)

Preparation

You need to set up a lab environment (Google Cloud and GitHub) to proceed with this exercise
- Lab Setup Procedure

Current State

Exercises procedure

Modify Go code and see automatic deployment
Add configuration via Terraform
(optional) read code

Exercises Procedure

1. Modify Go code and see automatic deployment

Access Cloud Run
- https://console.cloud.google.com/run
- You can get a URL from the console (Click the name of Cloud Run)
  - https://training-helloworld-*****.a.run.app
Modify message
- training-devenv-security/template/devenv-security-app/main.go
  
  Line 27 in 467bcce
  
  fmt.Fprintf(w, "Hello World!")
Re-Access Cloud Run
- Confirm an automated deployment

2. Add configuration via Terraform

Document: https://registry.terraform.io/providers/hashicorp/google/latest/docs
For instance, you can create a new service account like this configuration

resource "google_service_account" "test" {
  account_id = "service-account-id"
}

You can see the result on the web console: https://console.cloud.google.com/iam-admin/serviceaccounts

3. (optional) read code

Understand what happens from the source codes
