Tucano

An educational service scheduler and load balancer.

(WIP - improve README.)

Manually run locally with Docker

Build container and worker images:

docker build -f dockerfiles/node.dockerfile --build-arg='CRATE=ctl' --tag ctl .
docker build -f dockerfiles/node.dockerfile --build-arg='CRATE=worker' --tag worker .

The images don't define a Docker ENTRYPOINT rules. The container caller must manually execute the binary that is in /usr/local/bin. It may be ctl or worker.

Create a network that will be shared by the controller and worker nodes:

docker network create tucano-net

Run the controller:

docker container run --rm --network tucano-net --name ctl --entrypoint '/usr/local/bin/ctl' ctl

Fetch its designated IP address:

export TUC_CTL_IP="$(docker container inspect ctl --format '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}')"
echo "$TUC_CTL_IP"

Add as many worker nodes as you want:

docker container run --rm --network tucano-net --entrypoint '/usr/local/bin/worker' worker "--controller-addr=$TUC_CTL_IP"
