docker-compose.ci.yml

# This docker compose file is a minimal override file that goes with
# docker-compose.yml and is intended to be used in CI to run tests without
# a full environment (without running `make up`).
#
# Aside from overring healthchecks and dependencies, it does not bind mount the
# whole repos to /data/olympia, relying only on the contents of the image with
# named volumes for deps/node_modules as we need to install more on top of the
# production image for tests.
# Because it doesn't use a bound volume for the code, the entrypoint is also
# overridden as all the usermod shenanigans we'd normally need don't apply.
#
# Gotchas when running locally to test CI behavior:
# - Remove any stale stale data_deps_ci or data_node_modules_ci volumes
# - Use a production container with development deps. CI executes this first:
#   make up_pre DOCKER_VERSION=local \
#               DOCKER_DIGEST= \
#               DOCKER_TARGET=production \
#               OLYMPIA_DEPS=development
