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.

chrony cookbook

Build Status Cookbook Version

Configures the time synchronization application chrony as a client or master timeserver, maintaining the accuracy of the system clock (similar to NTP). Isolated networks are supported as well.



  • Debian / Ubuntu
  • CentOS / Redhat


  • Chef 13+



Configures the node to use the chrony application to keep the node's clock synced. If there is a node using the chrony::master recipe, the client will attempt to sync with it. If there is not an available master, the attribute list ['chrony'][:servers] is used (defaults are [0-3] If there is a master node, the ['chrony'][:allowed] and ['chrony']['initslewstep'] will be set to allow for syncing with the master.


The default recipe passes through to the client recipe.


The node will use the chrony application to provide time to nodes using the chrony::client recipe. The master sets its own time against the attribute list ['chrony'][:servers] (defaults are [0-3] Access to this master is restricted by the ['chrony'][:allowed] attribute set in the recipe (default is to the x.y.* subnet). If the ['chrony'][:servers] are empty, the master will set its ['chrony']['initslewstep'] to the first 3 client nodes returned by search (it will set it to the first 3 ['chrony'][:servers] otherwise).


Nodes using the chrony::client recipe will attempt to sync time with nodes using the chrony::master recipe. If there are no chrony::master nodes found, the contents of the attribute list ['chrony'][:servers] are used (defaults are [0-3]

The current configurations are supported:
1) Clients with direct NTP server access
2) A master with direct NTP server access with clients pointing to it
3) Isolated master and clients, using the initslewstep to keep the master and clients synced. Manually setting the server's time may be required.
