Kubernetes Handler module for AUTOQUBE load testing

Project description

This library contains:

  • Objects for
    • Creating, updating and deleting a Kubernetes cluster.

    • Deploying various objects on Kubernetes cluster.

    • Running Jmeter Load tests on Kubernetes cluster.

Table of Contents


python-autoqube_kubernetes is compatible with Python 3.x. It is listed on PyPi as ‘autoqube_kubernetes’. The recommended way to install is via pip:

pip install autoqube_kubernetes


  • kops: kops is a command line utility tool required to manage kubernetes cluster. The installation information is available at kops installation.

  • kubectl: kubectl is a command line utility tool required to manage various objects on existing kubernetes cluster. The installation information is available at kubectl installation.

  • dns-zone: A public hosted zone should be created for AWS which would be the same as the name of the cluster. Please refer creating dns-zone.


KubernetesHandler object will create, delete cluster and run load tests.

Kubernetes cluster

Currently the cluster creation is supported only on AWS cloud platform.

For creating a new Kubernetes cluster, the following parameters are needed:

  • cloud_provider : The cloud provider on which the cluster needs to be created.

  • cluster_config : The configuration details for the cluster.

  • env_config : The environment configuration for storage of cloud provider essential keys.

A typical cluster configuration file would be like

config = {
    "cloud_provider": "AWS",
    "cluster_config": {
        'node-count':  2,
        'master-size': 't2.small',
        'master-zones': 'us-west-2a',
        'zones':  'us-west-2a',
        'name': '',
        'node-size': 't2.small',
        'ssh-public-key': '/Users/autoqube/.ssh/',
        'dns-zone': '',
    "env_config": {
        'AWS_ACCESS_KEY_ID': '*********************',
        'AWS_SECRET_ACCESS_KEY': '***********************',
        'AWS_REGION': 'us-west-2',
        'KUBECONFIG': '/Users/autoqube/kubernetes/',
        'KOPS_STATE_STORE': 's3://agent-kops-store'

For better understanding or debugging of various processes running behind, setup a logging functionality.

from autoqube_kubernetes import KubernetesHandler
import config
import logging

root_logger = logging.getLogger()
console_handler = logging.StreamHandler()


kubernetes_handler = KubernetesHandler(config)
kubernetes_handler.create_cluster() # Creation of cluster with the above configuration.
# kubeconfig will be stored in the path specified in the configuration.
kubernetes_handler.delete_cluster() # Deletion of cluster with the above configuration.

Load Testing

  • Currently only ‘jmeter’ load testing is supported on kubernetes cluster.

  • Load testing using jmeter on a kubernetes cluster has been inspired from the following blog.

  • The results of the load test can be visually seen on grafana service dashboards.

  • The templates for deployment of various kubernetes objects required for jmeter load testing can be downloaded from Jmeter Load Test Templates.

  • Extract the downloaded templates and place them in location accessible by python.

  • The following parameters are needed for load testing
    • load_config - The configuration details about type of load test and the templates for kubernetes objects.

    • test_file_config - The configuration details about the test files for load test.

A sample configuration would be like

load_config = {
     'test_type': 'jmeter',
     'templates_path': '/Users/autoqube/kubernetes/load_testing/k8s_templates/jmeter/'
 test_file_config = {
     'test_files': ['./tmp/sample.jmx', './tmp/sample.csv']

KubernetesHandler will create the necessary objects on cluster and run load tests.

 # After creation of kubernetes cluster using 'kubernetes_handler'.
 # Creates pods, deployments, services and other objects required for
 # load testing on cluster.

 # Run load tests using the test files provided in the configuration

# Once the tests are complete, all the resources created can be destroyed
# and only empty cluster will remain.


KubernetesClient can be used to perform various actions on existing cluster like:
  • Creating objects from yaml files

  • Destroying resources on cluster

  • Listing all the pods and services on cluster

  • Executing commands on a specific pod

  • Copy files to a specific pod

kubeconfig of a cluster is required.

from autoqube_kubernetes import KubernetesClient

kubernetes_client = KubernetesClient('/path/to/kubeconfig')
namespace = 'autoqube' # Namespace on which the operations are to be performed.
kubernetes_client.create_object('/path/to/yaml', namespace) # Creates object from yaml file.
kubernetes_client.get_pod_list(namespace) # Lists all the pods.
kubernetes_client.get_service_list(namespace) # Lists all the services.
podname = 'autoqube-jmeter'
commands_list = ['cd ~', 'ls']
kubernetes_client.execute_commands(podname, commands_list, namespace) # Executes the commands on a specific pod.
kubernetes_client.destroy_all_resources(namespace) # Destroys all resources in a given namespace.
