A bake of a CI machine image runs test/docker/prepare-ci.ts. Its pull step ran `docker compose pull --ignore-pull-failures`, which exits 0 for a refused pull, and it printed a warning for each other failure. So a bake passed when the image of a test service could not be fetched. The pull step had one image to fetch, that of `redis_plain`, which no test starts. The service, the pull step and `withRedis()` are removed. prepare-ci.ts runs `docker compose build` only, and that step throws on a failure. `ensure()` starts a service with `docker compose up --pull never`, so a service with no `build:` section does not start. A source lint reports such a service in docker-compose.yml.

The CI runner passes a per-test timeout of 150 s for this file, so the explicit 30 s made the limit shorter there.

Question for a maintainer: is this rule wanted? Each compose service needs a
build:section. Notes give the alternative.Problem
pullImages()(test/docker/index.ts:489) runsdocker compose pull --ignore-pull-failures, which exits 0 for a refused pull.redis_plain, which no test starts. No test fails today.Fix
pullImages(),prepareImages(),redis_plainandwithRedis().prepare-ci.tsruns onlydocker compose build, which throws on failure.ensure()runscompose up --pull never, so a service withoutbuild:fails on its own PR. A lint reports it earlier.test/internal/docker-compose-helper.test.tsandtest/internal/source-lints/docker-compose-build.test.tsfail on main and pass here. In build 121739 the Linux x64 lanes started 284 services with the flag, 0 failed.postgres_auth(separate cleanup), runcompose buildfromspec.ts(renames 6 images).Background
prepare-ci.tsputs the service images on it. An existing image is not baked again.pull --ignore-buildable, ci: build the MinIO test image from source and fail the bake on a failed image pull #44041). Withoutredis_plainit fetches nothing.Downsides

The question

The lint reports it sooner, in theSource lintsjob.pullImages()stays and becomes strict (pull --ignore-buildableand a throw, as in ci: build the MinIO test image from source and fail the bake on a failed image pull #44041).--pull neverand the lint go.

doUp()builds the service beforeup, so each of the 10 services is in this case.up --pullis older thanup --wait-timeout(v2.17.0), whichdoUp()already uses.With a Docker daemon: build 121739 (f724ff8) ran the four Linux x64 lanes with the new arguments. The coordinator started 284 services (Alpine 64, Debian 71, Debian ASAN 78, Ubuntu 71), and each became ready. It started 9 of the 10 services.
