🪢 Infrastructure as Code Glue Code

Bridging the gap between declarative IaC tools and imperative shell scripting for complex automation workflows.

📖 Contents

• Shell in Terraform
• Shell in Ansible
• Shell in Pulumi
• When to Use Shell vs IaC
• Best Practices: Glue Code

🎯 Learning Objectives

✅ Master shell integration with Terraform, Ansible, and Pulumi ✅ Understand when to use shell vs declarative IaC ✅ Implement robust glue code patterns ✅ Build maintainable hybrid automation workflows ✅ Avoid common anti-patterns in IaC integration

🔍 Quick Reference

IaC Tool	Shell Integration	Use Cases
Terraform	local-exec, external data source	Pre/post hooks, custom provisioning
Ansible	shell, command, script modules	Ad-hoc tasks, complex logic
Pulumi	Native language shell execution	Dynamic resource creation
CloudFormation	AWS::CloudFormation::Init	Bootstrap scripts
