Workflow Tool Versions

Workflow tool-version sweep (Fission)

Playbook for refreshing the CLI tool versions that the Fission GitHub Actions workflows pin. Optimised for isolating regressions: each tool lands as its own commit so CI failure attribution is one click on git blame.

When to invoke

Trigger phrases: "update workflow tool versions", "bump skaffold/kind/cosign/helm", "what's outdated in our workflows", "process the dependabot github-actions PR", "CI tool refresh".

Skip if the user names a single tool and a single version — just edit and commit.

Scope (in order of priority)

1. Primary — env: block *_VERSION: vars. These are the versions the workflow downloads at runtime. This is the user's main scope.
2. Secondary — # vX.Y.Z comments next to SHA-pinned uses: actions. Dependabot already does these on a weekly schedule (.github/dependabot.yml has a github-actions group), so a manual sweep is mostly catch-up if Dependabot is behind.
3. Tertiary — matrix kindversion: (k8s node images for kind). Tied to kind release support windows; bump only when the underlying kind binary supports newer node images. Verify against kind release notes — kind v0.X.Y publishes a list of supported kindest/node tags.

Out of scope:

• with: version: "~> v2" (floating semver constraints — by design, no pin to bump).
• Tool versions referenced in Makefile, hack/, Dockerfiles, or goreleaser config — those live with the build code, not the workflow runners.

Known inventory (snapshot for orientation)

The skill should re-discover dynamically (see Phase 1) — but a recent snapshot for orientation:

SHA-pinned actions usually present:

• Azure/setup-helm, goreleaser/goreleaser-action, sigstore/cosign-installer, aquasecurity/trivy-action, helm/kind-action, step-security/harden-runner, actions/checkout, actions/setup-go.

Phase 0 — Baseline

1. Create branch off main. Check for a stale collision first — last month's branch is often still present locally and on origin after its PR merged, so git checkout -b ci/tool-versions-<YYYY-MM> fails with "branch already exists". If it exists, run gh pr list --head <branch> --state all; a MERGED PR means it's leftover (its bumps are already in main) — don't reuse it. Use a date-stamped name: git checkout main && git checkout -b ci/tool-versions-<YYYY-MM-DD>. After a recent merged sweep, expect most *_VERSION: vars to already be at latest — that's normal, not a discovery failure.
2. Inventory dynamically — do not trust the snapshot above:

   grep -rnE "^\s*[A-Z_]+_VERSION:" .github/workflows/
   

   Then for SHA-pinned actions with version comments:

   grep -rnE "uses:.*@[a-f0-9]{40} # v" .github/workflows/
   

3. Resolve each pinned tool to its upstream repo (see table) and fetch latest:

   for repo in helm/helm kubernetes-sigs/kind GoogleContainerTools/skaffold sigstore/cosign golangci/golangci-lint; do
     latest=$(gh api "repos/$repo/releases/latest" --jq '.tag_name')
     echo "$repo -> $latest"
   done
   

   gh api already authenticates; no token wrangling needed.

Phase 1 — Decide what to bump

Per tool, decide based on the size of the jump:

• Patch (vX.Y.Z → vX.Y.Z+n): take it unconditionally. Read the release notes only if the version skips many patches.
• Minor (vX.Y → vX.Y+1): read upstream release notes for breaking-ish changes — golangci-lint and skaffold periodically rename or drop linters/profiles. Helm minor bumps are usually safe; kind minor bumps may drop support for older kindest/node tags, so cross-check against the kindversion matrix.
• Major (vX → vX+1): don't lump into a sweep. Open a separate branch.

Flag deliberate stale pins:

• upgrade_test.yaml historically pins Helm v3.x while push_pr.yaml pins v4.x — upgrade_test simulates the v3-user upgrade path, so the v3 pin is intentional. Leave it unless the user says otherwise.
• kindversion: matrix entries that intentionally lag (testing k8s 1.28 LTS for backwards compat) — leave them unless the kind binary no longer ships a kindest/node:v1.28.x image.

Phase 2 — Per-tool workflow

For each tool to bump:

# Edit the *_VERSION: line(s). If the var is used in >1 workflow,
# bump them in the same commit IFF the workflows share intent
# (push_pr + release both want "latest stable kind"). Keep
# upgrade_test separate when it has its own intent.
$EDITOR .github/workflows/push_pr.yaml .github/workflows/release.yaml

# Sanity-check the YAML still parses. PyYAML is NOT installed on the dev macOS
# box (python3 -c "import yaml" -> ModuleNotFoundError), so prefer ruby, which ships
# with macOS and has YAML in stdlib. (For a pure value-only edit on a pre-valid line,
# YAML validity is preserved by construction — but validate anyway when in doubt.)
ruby -ryaml -e 'ARGV.each { |f| YAML.load_file(f) }; puts "YAML OK"' \
  .github/workflows/push_pr.yaml .github/workflows/release.yaml
# Fallback if ruby is absent: python3 -c "import yaml,sys; [yaml.safe_load(open(f)) for f in sys.argv[1:]]" <files>

git add .github/workflows/
git commit -m "Bump <tool> v<old> -> v<new>"

Commit message convention (matches Fission's existing dep-bump style):

Bump <tool> v<old> -> v<new>

<One line on why if it closes a CVE or unblocks a known issue.>

If the tool is in multiple files with the same intent (e.g. kind across push_pr and release), bump them in one commit. If intents differ (helm in push_pr-target vs upgrade_test-source), separate commits.

Phase 3 — Verification

There is no local equivalent for "did this workflow still pass" — CI is the test.

1. git log --oneline main..HEAD to review the per-tool commits.
2. git push -u origin <branch> and let CI run on the PR.
3. If a single tool's commit breaks CI, you can revert that one commit without affecting the rest. That's the point of the per-tool structure.

Pitfalls

Helm CLI version drift between push_pr and upgrade_test

upgrade_test.yaml pinning Helm v3.x while push_pr.yaml is on v4.x looks like a bug; it's deliberate (testing the "user is on Helm v3, upgrading their Fission install" path). Don't "fix" this by aligning them.

kindversion matrix is NOT the kind binary

KIND_VERSION is the kind CLI binary (kubernetes-sigs/kind). matrix.kindversion is the k8s node image tag (kindest/node:vX.Y.Z). They version separately. Updating one does not require updating the other, but the kind binary must still support the requested node-image tag — check the kind release notes' "Supported Kubernetes versions" table.

Skaffold breaking config changes

Skaffold occasionally renames or removes profile keys. The Fission skaffold.yaml uses kind, kind-ci, kind-debug, kind-opentelemetry profiles. After a skaffold bump, grep for apiVersion and kind: Config in skaffold.yaml and verify they match the new skaffold's expected schema. Most safe: download the new skaffold locally and run skaffold diagnose --profile kind-ci against the repo.

golangci-lint config schema migrations

v2.0.0 and v2.x.0 minors have repeatedly tightened the .golangci.yaml schema. If you bump and CI fails with a config-validation error, run golangci-lint config verify against the new binary locally. Sometimes the fix is to migrate a deprecated linter name; don't --no-config your way out.

cosign across two workflow jobs in release.yaml

release.yaml installs cosign twice (once in the release job, once in image-provenance-verification-with-cosign). Both read the same COSIGN_VERSION env, so a single bump covers both — but verify both still reference the env, not a hardcoded version, after editing.

Dependabot's grouped github-actions PR

Dependabot already groups action version bumps weekly (.github/dependabot.yml declares a github-actions group). The *_VERSION: env vars are NOT touched by Dependabot — those are runtime downloads, not action versions. So this skill's primary scope (env vars) does not overlap with Dependabot's; the SHA-pinned uses: bumps usually arrive via Dependabot, so manually doing them is catch-up if Dependabot is paused or behind.

Before deciding a SHA-pinned action is "behind," check for an open Dependabot PR: gh pr list --author "app/dependabot" --state open. If there's an open github-actions group PR (e.g. it bumps harden-runner/codeql-action/codecov-action/goreleaser-action), that PR already owns those SHA bumps — don't duplicate it in a sweep; flag it in the summary instead.

Bumping a SHA-pinned action when the user explicitly asks

The user may name a SHA-pinned action directly ("can we bump goreleaser too") even though it's normally Dependabot's domain. Do it, but:

1. Resolve the new tag to its commit SHA (the pin is a 40-hex SHA, not the tag): gh api repos/<owner>/<repo>/commits/<tag> --jq '.sha'. This dereferences annotated tags to the commit. Update both the @<sha> and the trailing # vX.Y.Z comment.
2. One action lives in multiple files — e.g. goreleaser/goreleaser-action is pinned in push_pr.yaml, upgrade_test.yaml, and release.yaml (×2). Replace every occurrence with the identical new @<sha> # vX.Y.Z and commit together. Edit with replace_all: true per file is reliable; a perl -pi -e "s{...}{...}" one-liner with the #/spaces in shell-expanded vars silently no-ops, so don't trust it without a grep re-check.
3. Flag the Dependabot overlap in the PR/summary if an open github-actions group PR also bumps it (it usually does), so the user can reconcile (whichever merges first, the other rebases/drops the entry).

Out of scope

• Tools versioned in Makefile, hack/, Dockerfile, or goreleaser config.
• Floating semver ranges (~> v2).
• Major version bumps — do those on a dedicated branch with their own validation plan.

Canonical execution (copy-paste outline for the model)

1. TaskCreate: baseline + one task per tool to bump + push/CI
2. git checkout -b ci/tool-versions-<YYYY-MM>
3. Discover pinned versions via grep on .github/workflows/
4. For each *_VERSION env var, gh api repos/<owner>/<repo>/releases/latest
5. For each tool to bump (patch/minor; defer majors):
     a. Edit the *_VERSION line(s); group same-intent files together
     b. Validate YAML parses (python3 yaml.safe_load)
     c. Commit per tool
6. git push and let CI verify
7. Summarize: commits on branch, versions bumped, deferred majors, flagged
   intentional stale pins (Helm v3 in upgrade_test).
