integration.yml

# The integration suites — the tests that need real infrastructure.
#
# They bring up Redis and RabbitMQ through Testcontainers, so they need a Docker daemon. The hosted
# Ubuntu runner has one, and the runner user is already in the docker group.
#
# Deliberately not a required check on pull requests. Container startup is the flakiest thing in
# this repository's CI, and a flaky required check teaches people to re-run rather than to read.
# Promote it once the suite has been stable for a stretch of runs.
