What You Need to Know About GitHub Agentic Workflows and Renovate
In this post, I want to describe the problem when combining the two, how I tried to fix it, and the correct solution.
GitHub Agentic Workflows and Renovate are two tools that can be used together to keep dependencies up-to-date in a repository. Renovate is a powerful tool that scans repositories for outdated package versions and automatically opens pull requests to bump them. It is similar to Dependabot, but with more ecosystem support and extensibility.
Agentic Workflows, on the other hand, allow users to create GitHub workflows in Markdown and compile them to generate GitHub Workflow-compliant YAML files. When combining these two tools, some issues can arise, particularly with GitHub actions dependencies.
One issue that can occur is that Renovate may bump a dependency SHA to a newer version, which in turn references a new version of a GitHub action. This can cause the workflow to fail when it tries to run the newer version of the GitHub action. One potential solution to this problem is to create a separate non-agentic GitHub workflow that runs whenever Renovate updates the lock file, and has the trigger only fire for changes to the GitHub action version.
However, this can still introduce problems if Renovate later updates other parts of the workflow, such as Node.js version pins.
The actual solution to this problem is to exclude the lock file from Renovate's processing. Renovate has an `ignorePaths` entry that can be used to exclude specific files from being processed. By adding the lock file and any other generated files to this list, Renovate will ignore them and prevent any issues from arising. Additionally, when updating the GitHub actions lock file manually, the `gh aw update-actions` command should be used to refresh the manifest file that Renovate relies on. This ensures that the pins in the lock file match the generated outputs from the compiler.
In conclusion, combining GitHub Agentic Workflows and Renovate can be a powerful way to keep dependencies up-to-date, but it requires careful attention to the generated files and proper configuration to avoid issues. By filtering out generated files, such as the GitHub actions lock file, and properly managing the manifest file, developers can ensure a smooth and error-free workflow.
