3. Agenda ・About Terraform Plugins ・Manage Spinnaker Applications w/ Terraform Providers ・Operation by Terraform Provisioners ・Wrap up
4. About Terraform Plugins
5. Terraform When terraform is executed...
6. Terraform = Terraform Core + Terraform Plugins Terraform Cores • Entrypoint for Terraform • Resource state management • Communicate with Terraform Plugins Terraform Plugins • Executable binary called by Terraform Core • Exposes an implementation for a specific services(GCP, AWS, local host, etc)
7. Terraform Plugins = Terraform Providers + Terraform Provisioners
8. Terraform Plugins = Terraform Providers + Terraform Provisioners Terraform Providers • Access external service APIs and CRUD resources • Managed Terraform State Terraform Provisioners • Run model specific actions for preparing the resources
9. Manage Spinnaker Applications by Terraform Provider
10. Spinnaker Spinnaker is an open source, multi-cloud continuous delivery platform
11. Spinnaker Spinnaker is an open source, multi-cloud continuous delivery platform Service Team Spinnaker Application Trigger Deploy
12. Spinnaker Spinnaker is an open source, multi-cloud continuous delivery platform Service Team Spinnaker Application Trigger Deploy How to manage Spinnaker Applications?
13. Terraform Providers The three kinds 1. Built-in Providers • Null provider • Secret provider • … 2. Hashicorp distributed Providers • terraform-provider-gcp • terraform-provider-aws • terraform-provider-vault
14. Terraform Providers The three kinds 3. Custom Providers • Third-party developed providers • Develop by yourself

16. Manage Spinnaker Applications CODE EDITOR resource “spinnaker_application” “my_app” { application = “my-app” email = “keke@hello.com” } resource “spinnaker_application” “my_test_app” { application = “my-test-app” email = “keke@hello.com” }
17. Manage Spinnaker Applications CODE EDITOR resource “spinnaker_application” “my_app” { application = “my-app” email = “keke@hello.com” } resource “spinnaker_application” “my_test_app” { application = “my-test-app” email = “keke@hello.com” }
18. Terraform Providers Take away To Terraform manage resources… 1. Check if there are built-in providers 2. Check if Hashicorp distributes the provider 3. Check custom provider in the community, GitHub, etc 4. Develop by yourself! Ideally, there are no limits what you can manage!
19. Terraform Providers Take away But… • Built-in provider: It’s built-in • Hashicorp distributed provider: Terraform will download on terraform init • Custom Provider: You need to manually download to your environment
20. Operation by Terraform Provisioner
21. Spinnaker Spinnaker is an open source, multi-cloud continuous delivery platform New Spinnaker Application Create Old Spinnaker Application
22. Spinnaker Spinnaker is an open source, multi-cloud continuous delivery platform New Spinnaker Application Create Old Spinnaker Application How to delete old application? Delete
23. Terraform Provisioners List of provisioners • Chef • File • habitat • puppet • remote-exec • salt-masterless • local-exec: Run any script on resource create or delete. See details Provisioners(https://www.terraform.io/docs/provisioners/index.html)
24. local-exec Terraform Provisioner Runs script on resource create CODE EDITOR resource “spinnaker_application” “my_app” { application = “my-app” email = “keke@hello.com provisioner “local-exec” { command = “./script/delete-app.sh my-old-app” } }
25. Terraform Provisioners Take away There are many actions provided by Terraform Provisioners. Ideally, you can run any operation by local-exec provisioner. Very useful for many use cases.
26. Terraform Provisioners Take away There are many actions provided by Terraform Provisioners. Ideally, you can run any operation by local-exec provisioner. Very useful for many use cases. No custom provisioners!
27. Wrap up
28. Manage Spinnaker Application by Terraform Plugins Managed Spinnaker application by custom Providers By developing custom Terraform Providers, you can ideally manage any resource. Start building one!
29. Manage Spinnaker Application by Terraform Plugins Managed Spinnaker application by custom Providers By developing custom Terraform Providers, you can ideally manage any resource. Start building one! Provisions are done by local-exec Provisioners Terraform is mainly used as provisioning tool but can be also used as configuration management tool.
30. Terraform has high extensibility which fits is many use cases
