3. Talking Points Terraform and Infrastructure as Code Introduction Terraforming Microsoft Azure Continuous Integration with GitHub Actions Terraform Resources
4. by HashiCorp • Toolset for Infrastructure as Code • Written in Go • Available for Windows, Linux, macOS, FreeBSD, OpenBSD, Solaris • Open Source • Optional paid services • Terraform Cloud (adds collaboration features) • Terraform Enterprise (adds governance features) Terraform
5. Terraform Write, Plan, and Create 1 Infrastructure as Code 2 Preview Changes before applying 3 Build reproducible infrastructure
6. Terraform Write, Plan, and Create 1 Infrastructure as Code 2 Preview Changes before applying 3 Build reproducible infrastructure
7. Infrastructure as Code • Automate your Infrastructure • Can be stored in a version control system (git) • Change History / Change Tracking • Collaboration • Better documentation • Eliminates the Truck Factor (or Single Point of Failure) • Predictable deployments Terraform - Write
8. Terraform Write, Plan, and Create 1 Infrastructure as Code 2 Preview Changes before applying 3 Build reproducible infrastructure
9. Preview changes before applying • Execution plan tells you which parts of the environment will be • Created • Modified • Deleted • Displayed / Verified before modifying the targeting infrastructure • Think of git status Terraform - Plan
10. Terraform Write, Plan, and Create 1 Infrastructure as Code 2 Preview Changes before applying 3 Build reproducible infrastructure
11. Build reproducible infrastructure • One Terraform script can be applied million times • Configurable environments • Variables • Interpolation • Built-in functions Terraform - Create
12. Write Code Terraform plan Verify Terraform apply Consume The Terraform Lifecycle Terraform Destroy
13. HashiCorp Configuration Language • Declarative language used to code your infrastructure • Based on JSON but more focused • Simple but powerful type system • Strings, Numbers, Booleans, Maps, Lists • One language for all infrastructure vendors • Using dedicated Providers Meet the HCL
14. Talking Points Terraform and Infrastructure as Code Introduction Terraforming Microsoft Azure Continuous Integration with GitHub Actions Terraform Resources
15. The AzureRM Provider • Terraform Provider supports all ARM API Features • Different Authentication patterns supported • Reuse Azure CLI Authentication • Dedicated Service Principal • Dedicated Managed Service Identity • Read/Write Azure Resources Terraforming Microsoft Azure
16. Demo Terraforming Microsoft Azure
