Question 1

How do I pass multiple var files in RubyTerraform?

Accepted Answer

Use the singular :var_file or plural :var_files option, as shown in the README—both are supported and can be combined, with all files passed to Terraform in order.

Question 2

RubyTerraform vs shelling out to Terraform directly?

Accepted Answer

RubyTerraform offers a cleaner, type-safe Ruby API that avoids brittle shell invocations and simplifies error handling, but adds a gem dependency. Shelling out is lighter for one-off scripts but harder to maintain.

Question 3

How to run Terraform commands in RSpec tests using RubyTerraform?

Accepted Answer

Require the gem and call methods like RubyTerraform.plan within test blocks, using parameters to simulate different scenarios. Configure I/O streams to capture output for assertions.

Question 4

Can RubyTerraform work with Terraform Cloud or Enterprise?

Accepted Answer

It can interact via CLI options like -backend-config, but lacks direct API integration. You'll need to rely on Terraform CLI's remote backend support, which might limit automation features.

Question 5

How to handle errors or retries when Terraform fails in RubyTerraform?

Accepted Answer

RubyTerraform raises exceptions on command failures; wrap calls in begin-rescue blocks and implement retry logic manually, as the gem doesn't provide built-in retry mechanisms.

Question 6

Is RubyTerraform compatible with the latest Terraform version?

Accepted Answer

It supports up to Terraform 1.5.7; check the project's GitHub for updates. Newer Terraform versions might work but could have unsupported options until the gem is updated.
