The Hoser runtime is responsible for taking a Hoser JSON graph file and executing it on actual hardware. The current implementation does it by spawning and supervising OS processes and connecting their stdio together similar to Unix pipes in shell works.
make install
hoser -h
See hoser-py on how to run sample pipelines using hoser.
With docker installed (see instructions on web), run:
make docker
which creates a local docker container with the tag hoser:latest-amd64. You can run examples/hello.hos
by running:
> docker run hoser:latest-amd64
