-###<a name="cluster-store"></a>Bypassing the Central Cluster Store When Building Docker Apps
-
-To run a Docker cluster without a central database, you need to ensure the following:
-
- 1. Run in "local" scope. This tells Docker to ignore any cross-host coordination.
- 2. Allow Weave to handle all the cross-host coordination and to set up all networks. This is done by using the `weave launch` command.
- 3. Provide an IP Address Management (IPAM) driver, which links to Weave Net's own IPAM system
-
-All cross-host coordination is handled by Weave Net's "mesh" communication, using gossipDNS and eventual consistency to avoid the need for constant communication and dependency on a central cluster store.
