Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

To create a managing node include swarm::manager in your node's run list To create a worker node include swarm::worker in your node's run list

Both of the above recipes assume that the Docker engine will be installed and running. swarm::service can be included if the engine is not managed through some other cookbook
