Deploying in Kubernetes/Openshift

A convenient alternative to running Hyperfoil on hosts with SSH access is deploying it in Kubernetes or Openshift. The recommended way to install it using an operator in your Openshift console - just go to Operators - OperatorHub and search for ‘hyperfoil’, and follow the installation wizard. Alternatively you can deploy the controller manually

In order to start a Hyperfoil Controller instance in your cluster, create a new namespace hyperfoil: Go to Operators - Installed Operators and open Hyperfoil. In upper left corner select ‘Project: ‘ - Create project and fill out the details. Then click on the ‘Hyperfoil’ tab and find the button ‘Create Hyperfoil’.

You should see a YAML definition like this:

apiVersion: hyperfoil.io/v1alpha2
kind: Hyperfoil
  name: example-hyperfoil
  namespace: hyperfoil
  agentDeployTimeout: 60000
  log: myConfigMap/log4j2-superverbose.xml
    host: hyperfoil.apps.mycloud.example.com
  version: latest

Change the name to just hyperfoil (or whatever you prefer) and delete all the content from the spec section:

apiVersion: hyperfoil.io/v1alpha2
kind: Hyperfoil
  name: hyperfoil
  namespace: hyperfoil

This is a perfectly valid Hyperfoil resource with everything set to default values. You can customize some properties in the spec section further - see the reference.

The operator deploys only the controller; each agent is then started when the run starts as a pod in the same namespace and stopped when the run completes.

When the resource becomes ready (you can check it out through Openshift CLI using oc get hf) the controller pod should be up and running. Now you can open Hyperfoil CLI and connect to the controller. While default Hyperfoil port is 8090, default route setting uses TLS (edge) and therefore Openshift router will expose the service on port 443. If your cluster’s certificate is not recognized (such as when using self-signed certificates) you need to use --insecure (or -k) option.

> bin/cli.sh
[hyperfoil]$ connect hyperfoil-hyperfoil.apps.my.cluster.domain:443 --insecure
WARNING: Hyperfoil TLS certificate validity is not checked. Your credentials might get compromised.
WARNING: Server time seems to be off by 12124 ms

Now you can upload & run benchmarks as usual - we’re using k8s-hello-world.hf.yaml in this example. Note that it can take several seconds to spin up containers with agents.

[hyperfoil@hyperfoil-hyperfoil]$ upload examples/k8s-hello-world.hf.yaml

[hyperfoil@hyperfoil-hyperfoil]$ run k8s-hello-world

You can find more details about adjusting the agents in the benchmark format reference.

Running Hyperfoil inside the cluster you are trying to test might skew results due to different network topology compared to driving the load from ‘outside’ (as real users would do). It is your responsibility to validate if your setup and separation between load driver and SUT (system under test) is correct. You have been warned.


Property Description
version Tag for controller image (e.g. 0.14 for a released version or 0.15-SNAPSHOT for last build from main (master) branch). Defaults to latest.
image Controller image. If ‘version’ is defined, too, the tag is replaced (or appended). Defaults to ‘quay.io/hyperfoil/hyperfoil’
route Configuration for the route leading to Controller REST endpoint.
auth Authorization configuration.
log Name of the config map and optionally its entry (separated by ‘/’: e.g myconfigmap/log4j2-superverbose.xml) storing Log4j2 configuration file. By default the Controller uses its embedded configuration.
agentDeployTimeout Deploy timeout for agents, in milliseconds.
triggerUrl Value for io.hyperfoil.trigger.url - see above
preHooks List of config map names holding hooks that run before the run starts.
postHooks List of config map names holding hooks that run when the run finishes.
persistentVolumeClaim Name of the PVC Hyperfoil should mount for its workdir.


Property Description
host Host for the route leading to Controller REST endpoint. Example: hyperfoil.apps.cloud.example.com
type Either ‘http’ (for plain-text routes - not recommended), ‘edge’, ‘reencrypt’ or ‘passthrough’
tls Name of the secret hosting tls.crt, tls.key and optionally ca.crt. This is mandatory for passthrough routes and optional for edge and reencrypt routes


Property Description
secret Name of secret used for basic authentication. Must contain key password; Hyperfoil accepts any username for login.
