Renovate

Renovate is a tool for automatically updating dependencies in a codebase. It is very powerful and flexible, and you can think of it as Dependabot on steroids. While it supports every ecosystem under the sun, our default configuration only uses it to automatically update templates from the Golden Path through Pull Requests. We run Renovate as a scheduled GitHub Actions workflow in golden-path-renovate.

How do I use it?

Renovate regularly opens Pull Requests in enrolled repositories, and by default only updates Golden Path templates.

Handling an update to a Terraform template

  1. Read the release notes to understand the changes.
    These can be especially useful when updating major versions as that typically implies some kind of breaking change that requires manual intervention.
  2. Apply the changes in a PR as you normally would any Terraform change.
    If it's a minor or patch update, you should typically be able to apply the changes as-is. If you don't have a CI/CD pipeline for your infrastructure, pull down the branch locally, navigate to the affected directory, run Terraform manually (i.e., terraform init, terraform plan, terraform apply, etc.), and finally merge the PR.

Familiarize yourself with the Dependency Dashboard

Renovate will create an issue named Dependency Dashboard the first time it runs against a repository. This issue will show you all the available updates, and can also be used to manually select which updates Renovate should create Pull Requests for on its next run.

Details

  • The renovate.json5 file in your repository defines Renovate's behavior when running against your repository. Feel free to customize this if you'd like - there are many options.
  • At most 4 PRs from Renovate are open at once unless temporarily overridden (through the Dependency Dashboard) or on a more permanent basis (through the renovate.json5 configuration file).
  • Renovate runs every weekday on an hourly schedule. You can also manually trigger this GitHub Actions workflow to have Renovate run immediately against your repository instead of waiting for the next scheduled run (e.g., if you've made changes through the Dependency Dashboard that you want to take effect ASAP).
