Provisioning a Lattice
All wasmCloud hosts are segmented into distinct namespaces called lattices.
When running locally with wash up
, the lattice name defaults to default
. In production, it's common to run multiple lattices on the same NATS cluster, where each lattice gets its own name.
From a provisioning perspective, a lattice is little more than:
- a name(space)
- NATS subject hierarchies based off the namespace: (
wasmbus.ctl.{lattice-id}.>
,wasmbus.rpc.{lattice-id}.>
,wasmbus.evt.{lattice-id}.>
, etc.) - lattice metadata, which is stored in JetStream as a
LATTICEDATA_{lattice-id}
Key Value bucket - lattice cluster keys
- one or more running hosts
The following guides explain how to create and manage each of these components.
