The govulncheck workflow from google/trillian, explained and optimized by Latchkey.

What it does

This is the govulncheck workflow from the google/trillian repository, a real project running GitHub Actions. It is shown here with attribution under its Apache-2.0 license.

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
