Quick Start with Docker

Start the onesparse demo docker container, substitute suitable password and container name:

docker run -d -e POSTGRES_PASSWORD=password -it --name onesparse-demo onesparse/onesparse:demo

The container will start detached in the background, verify it's running with 'docker ps'. Now exec a psql process to interact with the container:

docker exec -u postgres -it onesparse-demo psql

postgres# create extension onesparse;
CREATE EXTENSION
postgres# select print(random_matrix(8, 8, 16, seed=>0.42, max=>42)) as random_matrix;
