kubemarks: KUBErnetes benchMARKS

kubemarks is a benchmarking tool based on Google Cloud Platform's PerfKit Benchmarker that can periodically run benchmarks as CronJobs on Kubernetes. Results can be exposed to a Prometheus Pushgateway.

Supported benchmarks

• block_storage_workload
• cluster_boot
• fio
• iperf
• mesh_network
• netperf

How to run it

Benchmarks are periodically launched as a CronJob.

Steps

1. Clone this repository:

   $ git clone git@github.com:marcomicera/kubemarks.git
   $ cd kubemarks
   $ git submodule update --init --recursive

2. Set the number of pods to be used for each benchmark in the yaml/base/kubemarks-num-pods.yaml file
3. Set the Pushgateway address in yaml/base/kubemarks-conf.yaml
4. Launch a benchmark periodically. E.g., for iperf:

   $ kubectl kustomize yaml/benchmarks/iperf | kubectl apply -f -

Launch more benchmarks programmatically

1. Define the list of benchmarks to run (and the Pushgateway address) in yaml/base/kubemarks-conf.yaml
2. Set the number of pods to be used for each benchmark in the yaml/base/kubemarks-num-pods.yaml file
3. Set the frequency with which benchmarks will be run in yaml/base/kubemarks-pkb-cronjob.yaml

   schedule: '0 * * * *'

4. Launch this set of benchmarks periodically:

   $ kubectl kustomize yaml/base | kubectl apply -f -
