Bump Test Image

Bump default docker test image

Updates the default redislabs/client-libs-test docker tag used by tests (a single shared config in @redis/test-utils), adjusts the CI matrix, commits on a freshly-reset bump-test-image branch, force-pushes it, and opens (or updates) a PR against redis/node-redis master.

Inputs

• tag (required): the new docker tag, e.g. 8.8.0, 8.8-rc1, custom-28772936538-debian, unstable-24425681442-debian. If given as redislabs/client-libs-test:<tag>, strip the image name.
• version (sometimes required): the Redis version the tag represents, e.g. 8.10.
• Derivable when the tag is version-shaped: 8.8.0 → 8.8, 8.8-rc1 → 8.8, 8.8-m03 → 8.8.
• NOT derivable for custom-* / unstable-* tags — if missing, ask the user which Redis version the tag maps to before doing anything else.

If no tag was given at all, ask for it and stop.

Step 1 — Sync master from upstream

Remotes: upstream = redis/node-redis (canonical), origin = the user's fork.

git fetch upstream
git rev-parse --abbrev-ref HEAD   # remember current branch

Update local master to upstream:

• If currently on master: git reset --hard upstream/master (only if working tree is clean — if dirty, stop and tell the user).
• Otherwise: git fetch upstream master:master (fails safely if master has local-only commits; if it fails, stop and report).

Step 2 — Reset the work branch

git checkout -B bump-test-image master

-B creates or hard-resets the branch to latest master. Any previous bump commits on it are intentionally discarded (the branch is recycled for each bump; force-push later matches this).

Step 3 — Edit the shared default config

The default image config lives in exactly ONE place:

packages/test-utils/lib/index.ts → DEFAULT_DOCKER_CONFIG:

export const DEFAULT_DOCKER_CONFIG: TestUtilsConfig = {
  dockerImageName: 'redislabs/client-libs-test',
  dockerImageTagArgument: 'redis-tag',
  dockerImageVersionArgument: 'redis-version',
  defaultDockerVersion: { tag: '<old-tag>', version: '<old-version>' }
};

Note the old tag/version, then replace them with the new values on the defaultDockerVersion line. Nothing else in the file changes.

If DEFAULT_DOCKER_CONFIG does not exist in that file (e.g. master predates the dedupe refactor), STOP and tell the user — do not fall back to editing per-package test-utils files without confirmation.

Step 4 — Update the CI matrix

File: .github/workflows/tests.yml, matrix → redis entries of the form:

          - tag: "8.8.0"
            version: "8.8"

Two cases, decided by comparing the new version with the old default version from Step 3:

• New Redis version (e.g. default moves 8.8 → 8.10): add a new - tag/version entry at the end of the matrix list, keeping the previous entry so CI retains coverage of the prior version.
• Same Redis version (rc → GA, or a newer custom build of the same version): replace the tag of the existing entry for that version; the version line stays.

Step 5 — Verify

grep -rn "defaultDockerVersion:" packages --include="*.ts" | grep -v dist | grep -v node_modules

Exactly one config line (in packages/test-utils/lib/index.ts) must show the new tag/version; any other hits are the type definition / JSDoc examples, not real defaults. Also confirm git diff --stat touches exactly 2 files: packages/test-utils/lib/index.ts + .github/workflows/tests.yml.

Step 6 — Commit

Fill in this template exactly (Conventional Commits):

chore(tests): bump default docker test image to <X>

Bump the default Redis test image from <old-tag> to <new-tag> (Redis
<version>) in DEFAULT_DOCKER_CONFIG, and <matrix-action> the CI matrix.

• <X>: the human-meaningful version when the tag is version-shaped (8.10, 8.8.0, 8.8-rc1, 8.8-m03); the full tag for unstable-* builds; the version for custom-* tags (the actual tag already appears in the body as <new-tag>).
• <matrix-action>: either add an <version> entry to (keeping prior-version coverage) or update the <version> entry in, matching what Step 4 did.

Example:

chore(tests): bump default docker test image to 8.10

Bump the default Redis test image from 8.8.0 to custom-28772936538-debian
(Redis 8.10) in DEFAULT_DOCKER_CONFIG, and add an 8.10 entry to the CI
matrix.

Keep any company-internal references (Jira/Confluence IDs, internal links) out of the commit and PR.

Step 7 — Force-push and PR

git push -f origin bump-test-image

Then check for an existing open PR before creating one:

gh pr list --repo redis/node-redis --head <fork-owner>:bump-test-image --state open

(<fork-owner> = GitHub owner from the origin remote URL.)

• If a PR exists, the force-push already updated it — just report the URL. Update its title/body via gh pr edit to match the new tag.
• Otherwise create one:

gh pr create --repo redis/node-redis --base master --head <fork-owner>:bump-test-image \
  --title "<commit subject>" \
  --body "<commit body>"

Finish by reporting: old → new tag/version, matrix action taken (added vs replaced entry), and the PR URL.
