What is terraform-operator?

This project is:

• A way to run Terraform in Kubernetes by defining Terraform deployments as Kubernetes manifests
• A controller that configures and starts Terraform Workflows when it sees changes to the Kubernetes manifest
• Workflow runner pods that execute Terraform plan/apply and other user-defined scripts

Debug With tfo CLI

Terraform is great, but every now and then, a module takes a turn for the worse and the workflow fails. When this happens, a terraform workflow will need to be "debugged."

Fortunately, the tfo cli (https://github.com/isaaguilar/terraform-operator-cli) can be used to start a debug pod which is connected directly to the same terraform session the workflow runs. It does so by reading the TFO resource and generates a pod with the same environment vars, ConfigMaps, Secrets, and ServiceAccount as a regular workflow pod. Then it drops the user in a shell directly in the main module.

tfo debug my-tfo-resource --namespace default

The user should be ready to rock-n-roll and show off their mad debugging skills.

Try running 'terraform init'

/home/tfo-runner/generations/2/main$

Happy debugging!
