## Common questions

### How do I pass remote state backend settings to OpenTofu during init?

Add the required values with -backend-config flags when you run tofu init. If the backend settings are missing, OpenTofu may not find or connect to the state backend you intend to use.

### Can I cache provider plugins so repeated tofu init runs do not re-download them?

Set TF_PLUGIN_CACHE_DIR to a folder such as ~/.tofu.d/plugin-cache before running tofu init. This stores provider plugins in a shared place so later runs can reuse them.

### Can I switch from Terraform without rewriting my existing configuration?

OpenTofu is described as a drop-in replacement for Terraform that preserves your existing workflows and configurations.

### Are OpenTofu nightly builds suitable for production?

No. Nightly builds are experimental, are not intended for production use, and are removed after 30 days.

### What OpenTofu CI/CD issue was reported for self-managed GitLab?

A user reported a failed attempt to migrate Terraform CI/CD templates to the OpenTofu component on a self-managed GitLab install. They said they had to mirror a full repository and maintain it.
