Question 1

How to integrate tfupdate with GitHub Actions?

Accepted Answer

You can set up a workflow that runs tfupdate commands in a job, using environment variables for tokens and scripting to create pull requests, similar to the provided CircleCI example. Ensure you install tfupdate via binary or Docker in the runner.

Question 2

tfupdate vs terraform providers lock: which is better for updating lock files?

Accepted Answer

tfupdate is faster for bulk updates across directories without Terraform CLI, but terraform providers lock handles more complex dependency scenarios with version constraints. Choose tfupdate for performance in scattered projects, and Terraform CLI for comprehensive dependency resolution.

Question 3

How to update all provider versions in a directory recursively?

Accepted Answer

Use 'tfupdate provider <name> -r ./' to recursively update a specific provider, or combine with scripts for multiple providers. The README shows examples with the -r flag for recursive updates and optional version specification.

Question 4

Does tfupdate work with private Terraform module registries?

Accepted Answer

Yes, but it requires setting environment variables like tokens or custom base URLs. For private GitHub or GitLab repos, export GITHUB_TOKEN or GITLAB_TOKEN; for custom registries, adjust TFREGISTRY_BASE_URL as per the README.

Question 5

Can tfupdate handle version constraints like '>= 1.0' in updates?

Accepted Answer

Yes, tfupdate accepts version constraint expressions as input, allowing updates to constraints like '>= 1.0' for providers and modules. However, for lock file updates, it assumes pinned versions and may not process constraints fully.

Question 6

How to ignore certain folders when using tfupdate recursively?

Accepted Answer

Use the -i flag with a regular expression, e.g., '-i vendor/' to exclude paths. The README provides examples of ignoring directories like 'modules/' during recursive updates.
