Docker Compose is a convenient way to launch a cluister when testing locally. The following Docker Compose example demonstrates how to start a cluster using a single process that acts as both a scheduler and an executor, with a data volume mounted into the container so that Ballista can access the host file system.
version: '2.0' services: etcd: image: quay.io/coreos/etcd:v3.4.9 command: "etcd -advertise-client-urls http://etcd:2379 -listen-client-urls http://0.0.0.0:2379" ports: - "2379:2379" ballista-executor: image: ballistacompute/ballista-rust:0.4.1 command: "/executor --bind-host 0.0.0.0 --port 50051 --local" environment: - RUST_LOG=info ports: - "50050:50050" - "50051:50051" volumes: - ./data:/data
With the above content saved to a
docker-compose.yaml file, the following command can be used to start the single
The scheduler listens on port 50050 and this is the port that clients will need to connect to.
