Per Istio's installation instructions for Minikube, ensure your instance has at least 4 CPUs and 8096 MB of RAM.

Usage:

  # finally, deploy the baseline, Linkerd2-meshed and Istio-meshed echo servers
  $ CMD=INIT ./minikube.sh

  # also, deploy the report server
  $ CMD=RUN_TESTS ./minikube.sh

  # delete the linkerd, istio-system, benchmark-baseline, benchmark-linkerd, benchmark-istio namespaces
  $ CMD=CLEANUP ./minikube.sh
