Automating Terraform with GitHub Actions

This repo is a part of Medium Article.
Follow Medium blog for steps: Automating Terraform with GitHub Actions

Main Points

• GCS bucket is serving as terraform backend.
• Workflow offers concurrency which means only one workflow can be run at a time; I’ve done this to prevent our terraform state from locking and getting corrupted.
• GitHub secrets are being used to pass GCP Service Account credentials safely on runtime.
• Terraform Plan generates a plan file which is further used by terraform apply. This is done to prevent uninformed changes b/w plan and apply.
• Terraform code must be properly formatted which is considered a good practice else terraform format validation will throw an error and the pipeline would get stopped.
• Manual Approval before applying terraform apply stage.
• Slack Integration for Workflow Alerts.
