Oracle Functions LoadBalancer

Loadbalancing several Oracle Functions

You can run multiple Oracle Functions instances and balance the load amongst them using fnlb as follows:

fnlb --listen <address-for-incoming> --nodes <node1>,<node2>,<node3>

And redirect all traffic to the load balancer.

NOTE: For the load balancer to work all function nodes need to be sharing the same DB.

Running with docker

make docker-build
make docker-run
curl -X PUT -d '{"node":"127.0.0.1:8080"}' localhost:8081/1/lb/nodes

127.0.0.1:8080 should be the address of a functions server. The lb will health check this and log if it cannot reach that node. By default, docker-run runs with --net=host and should work out of the box. Any number of functions servers may be added to the load balancer.

To make functions requests against the lb:

API_URL=http://localhost:8081 fn call my/function
