# This file deploys Gurobi Cluster Manager and Compute Server Nodes
#
# 1- Create the license file as a secret
#    kubectl create secret generic gurobi-lic --from-file="gurobi.lic=$PWD/gurobi.lic"
#
# 2- Deploy the cluster manager with compute server nodes
#    kubectl apply -f k8s.yaml
#### To keep the demonstration simple, this deployment file will not persist the database.
#### If you wish to do so, please refer to the MongoDB documentation or a hosted solution (for example MongoDB Atlas).
