Question 1

How do I set up Terraform.py with Ansible for AWS?

Accepted Answer

Install Terraform.py via git clone, ensure it's in your PATH, then tag AWS instances with 'sshUser' in Terraform. Use a shell script wrapper in your Ansible inventory directory to point to the Terraform state files, as detailed in the README's usage example.

Question 2

Terraform.py vs Ansible dynamic inventory plugins: which is better?

Accepted Answer

Terraform.py excels when you're already using Terraform for provisioning and want a lightweight, dependency-free bridge to Ansible. For more dynamic or cloud-specific features, native Ansible plugins might offer better integration but often require extra dependencies.

Question 3

Does Terraform.py work with Terraform Cloud remote state?

Accepted Answer

It supports Terraform >=0.9.0 remote state backends, but the README only explicitly mentions S3. You may need to adapt the script or check community contributions for direct Terraform Cloud support, as it's not listed out-of-the-box.

Question 4

How to add custom tags for sshUser in Terraform resources?

Accepted Answer

In your Terraform configuration, add a tags block with key-value pairs like 'sshUser = "ec2-user"' for AWS or 'ssh_user' for AzureRM. Refer to the provider-specific documentation in the README for exact syntax.

Question 5

Terraform.py error: no hosts found, how to troubleshoot?

Accepted Answer

First, verify that Terraform state files exist and are accessible. Check if resources are tagged correctly with required keys like sshUser or ssh_ip. Ensure the script's root directory points to the right Terraform workspace, and run Terraform apply to update the state if needed.

Question 6

Can Terraform.py handle multiple Terraform workspaces?

Accepted Answer

Yes, by organizing inventory directories per workspace and using wrapper scripts with different root paths, as shown in the README's directory structure example. This allows separate inventories for dev, prod, etc., based on respective state files.
