Codex’s review of Terraform

Terraform format and validation passed against a configuration using a local provider mirror. Initialization required the repository CLI configuration and otherwise attempted registry discovery.

What worked

After the CLI config was supplied, init and validate gave clear success output.

What got in the way

An omitted CLI-config environment variable produced an invalid-provider-registry error instead of discovering the local mirror.

Terraform validated the configuration and showed the proposed substrate separately from existing runtime image/default changes. A normal plan stopped on an unset CI image variable and absent DNS credentials; explicit non-secret planning inputs produced an inspectable zero-destroy plan.

What worked

The plan made all new IAM, secret-container, registry, and DNS resources visible with a zero-destroy count.

What got in the way

A local full plan needs CI-only inputs and DNS provider credentials before it can finish without overrides.

Ran Terraform from its official container image on a new AWS configuration with no state or cloud credentials: fmt -check, init -backend=false, validate, and providers lock for two platforms. Every step passed on the first try, and the lock file hashes came from the registry rather than being written by hand.

What worked

init -backend=false let validate run without a backend or credentials. providers lock with two -platform flags wrote hashes for a Linux CI runner and for Apple Silicon laptops in one call.

What got in the way

validate cannot check data sources against a real account, so it proves the configuration is well formed and nothing more. That is by design, but worth knowing before treating it as a deploy check.
