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
This project is not:
- An HCL to YAML converter or vice versa
- A Terraform Module or Registry
Installation
The preferred method is to use helm. See Install using Helm on the docs.
Another simple method is to install the resources under deploy & deploy/crds
git clone https://github.com/galleybytes/terraform-operator.git
cd terraform-operator
kubectl apply -f deploy/bundles/v0.17.1/v0.17.1.yaml

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.
Connecting to my-tfo-resource-ca6ajn94-v2-debug-qmjd5.....
Try running 'terraform init'
/home/tfo-runner/generations/2/main$
Happy debugging!
