flotilla/e2e/harness/zooid/docker/compose.yaml

# The relay the whole suite runs against. Bound to loopback only, and the one server this harness is
# allowed to connect to for real.
#
# The image is distroless and runs as `nonroot`. zooid creates DATA and MEDIA itself, but it cannot
# create their parent /app, so both have to arrive already mounted — and writable by uid 65532,
# which is what `mode` below is for: docker defaults a tmpfs to 1777 and podman does not, and a
# tmpfs the relay cannot write is a container that exits 1 the moment it opens its database.
# Nothing is persisted, so `up --force-recreate` is a guaranteed-empty database.
