  npm install https://github.com/dice-cyfronet/hyperflow/archive/1.1.0.tar.gz

###Running

• Start the redis server: redis-server

• Run example workflows using command hflow run <wf_directory>, for example:
  ./bin/hflow run ./examples/Sqrsum
• Optionally, you can add directory <hyperflow_root_dir>/bin to your system PATH

###Using docker image

• Build the image: docker build -t hyperflow .
• Start redis container: docker run --name redis -d redis
  • [OPTIONAL] If you plan on using amqp executor, start a rabbitmq container: docker run -d --name rabbitmq rabbitmq:3
• Run hyperflow server: docker run -d --rm --link=redis -e "REDIS_URL=redis://redis" --name hyperflow -p 8080:80 hyperflow
  • [OPTIONAL] or with amqp executor: docker run -d --rm --link=rabbitmq --link=redis -e "AMQP_URL=amqp://rabbitmq" -e "REDIS_URL=redis://redis" --name hyperflow -p 8080:80 hyperflow
• Verify that the server responds with: curl localhost:8080 -v, the output should contain a string: Cannot GET /
