You need to install Docker (and docker-compose, which is included in all recent releases of Docker).

You can run the application with this command (from the top-level directory of the repo):

docker-compose up

The app is configured with the following containers:

• primary - this is the application with LiteFS running as primary (all writes happen on this node)
• replica1 - this is the application running with LiteFS as a replica
• nginx - nginx configured as a load balancer, and also configured to route all POST requests to the primary node

Each of these is available to test out locally:

• http://localhost:8080 - the load balancer
• http://localhost:8081 - the primary
• http://localhost:8082 - the replica

You can test generating records on each node (it will fail if attempted on the replica).
