Go workflow (talent-plan/tinykv)

The Go workflow from talent-plan/tinykv, explained and optimized by Latchkey.

What it does

This is the Go workflow from the talent-plan/tinykv repository, a real project running GitHub Actions. It is shown here with attribution under its Apache-2.0 license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

name: Go
on: [push,pull_request]
jobs:

  build:
    name: Build & Test
    runs-on: ubuntu-latest
    steps:

    - name: Set up Go 1.13
      uses: actions/setup-go@v1
      with:
        go-version: 1.13
      id: go

    - name: Check out code into the Go module directory
      uses: actions/checkout@v1

    - name: Build & Test
      run: make ci

The same workflow, on Latchkey

Removes redundant runs and caps runaway jobs. Added and changed lines are highlighted.

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• Cancel superseded runs when a branch or PR gets a newer push.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.
