 # flotta-scale-tests
 The purpose of this project is to test the scalability and performance of [project-flotta](https://github.com/project-flotta/flotta-operator) using [JMeter](https://jmeter.apache.org).
 
+## Install OCP SNO cluster
+Clone https://gitlab.cee.redhat.com/jgil/simple-openshift-cluster-provisioner
+Run `CLUSTER_NAME=<cluster name> SNO_MASTER_MEMORY=<amount of memory in Mib> SNO_MASTER_CPU=<amount of CPU> make create_sno_cluster`.
+
+Ex: `CLUSTER_NAME=devicemgmt1 SNO_MASTER_MEMORY=64000 SNO_MASTER_CPU=16 make create_sno_cluster`
+## Configure K8S/OCP cluster
+Follow https://metallb.universe.tf/installation/ to avoid having to create NodePort service to expose the flotta operator
+See https://metallb.universe.tf/configuration/#layer-2-configuration. Use `kubectl get nodes -o` or `oc get nodes -o wide` to get the IP adress.
+
 ## Running the test plan
 Use [./scripts/run_test_plan.sh](./scripts/run_test_plan.sh) to run the test plan.
 The script will create the required resources on the cluster for running the test.
