Minikube load balancing demo
Here's a quick demo of load balancing in minikube
# Start the cluster. Takes a minute. Be patient.
make mk-start
# Build the Docker image, start your K8S services + deployments
make mk-build kb-create
# Wait for your pods to start
# kubectl get svc,deploy,po
kubectl get --watch po
# Hit the endpoint multiple times and observe load balancing in action
for i in $(seq 1 7); do printf "Request #$i: "; curl $(minikube service hello-world-go-api --url)/id; echo ""; doneBenchmarks
Load tests show nearly 80k requests per second.
