Several e2e tests used fixed host ports (8070, 8080, 8090, etc.), global
buildx builders registered with --use, and a hardcoded IPC container name.
Under parallel execution these shared daemon-level resources caused port
conflicts, buildkitd container-name collisions, and intermittent failures.
Separately, the standalone make target hardcoded -parallel=1, forcing the
entire standalone suite to run serially even though the same tests run in
parallel in plugin mode.
Changes:
- Convert fixed host ports in four fixtures (network-test, sentences,
build-test, volume-test) to ephemeral bindings; add ServicePublishedPort
helper to framework.go to resolve the actual mapped port at runtime.
- Give each buildx-builder test a unique daemon-scoped name via BuilderName
helper, preventing container-name collisions between parallel goroutines.
Applies to TestBuildPlatformsWithCorrectBuildxConfig, TestBuildPrivileged,
TestBuildBuilder, TestBuildEntitlements, TestBuildTLS.
- Rename the fixed ipc_mode_container to a project-scoped name
(ipc_e2e-src) and update the ipc-test fixture accordingly.
- Replace the hardcoded -parallel=1 in make e2e-compose-standalone with
E2E_PARALLEL_PLUGIN?=4 and E2E_STANDALONE_PARALLEL?=4, aligning both
modes with the effective GOMAXPROCS on 4-core GitHub Actions runners.
Both variables are overridable (E2E_STANDALONE_PARALLEL=1 restores
serial local debugging).
- Raise the poll delay in watch_test.go long-running polls (90s/120s
timeout) from the default 100ms to 1s; bump cascade_test.go and
publish_test.go from 100ms to 500ms. Reduces CPU pressure without
affecting effective test duration.
The logging-driver fixture retains its fixed port 24224: the Docker fluentd
log driver encodes fluentd-address at service-start time, making ephemeral
resolution non-trivial. TestLoggingDriver is serial so there is no
collision risk in practice.
