# build into OCI containers. The docker-compose is being run as a Podman Service
# systemd's socket unit file. There is no need for "--file=" flag because of
# the build context that is being specified into the compose.yml. Without this,
# the COPY build context would be difficult because there would be the need of a
# script workaround since the build context for the container runtimes is the same
# as where the Dockerfile is located, passed by the "--file=" argument flag.
#
# btw, the same is true for the context of the .dockerignore. So, the OCI build
# context affects at least: dockerfile COPY build context and .dockerignore
