Description

I changed the workflow to cache dependencies using actions/setup-go. actions/setup-go@v3 or newer has caching built-in.

AS-IS

- name: Install Go
  uses: actions/setup-go@v2
  with:
    go-version: '1.19.1'
- name: Checkout
  uses: actions/checkout@v2
  with:
    fetch-depth: 1

TO-BE

- name: Checkout
  uses: actions/checkout@v3
  with:
    fetch-depth: 1
- name: Install Go
  uses: actions/setup-go@v3
  with:
    go-version: '1.19.1'
    check-latest: true
    cache: true
    cache-dependency-path: |
          **/go.sum
          **/go.mod

This looks good although I'm not sure exactly where the speedup is supposed to be visible?

@brandond It should cache the ginkgo and gomega packages, since those are downloaded when running go test. But your correct in that I don't expect must speed up. We aren't caching any of the k3s build dependencies, we don't built K3s in these jobs.
