What is Gatling Commander ?

Gatling Commander is a CLI tool that automates a series of tasks in the execution of load test using Gatling Operator.
Gatling Operator is a Kubernetes Operator for running automated distributed Gatling load test.

Features

By writing load test scenarios in the configuration file, Gatling Commander automatically run load test and record the results.

Gatling Commander automates the following tasks.

  • Create Gatling objects for each load test
  • Build Gatling image
  • Stop load test when result latency exceeds a predefined threshold
  • Record Gatling Report and target container metrics for each load test
  • Check running load test status

In addition, Gatling Commander allow to have multiple load test scenarios in the configuration file.

After preparing the configuration file, run the gatling-commander command, this will automatically run all load test and record the results to Google Sheets.
Gatling Commander notify load test finished status to Slack as configured in the configuration file.

Please refer to User Guide about details of each field in the configuration.

Here is an example of how to fill out the configuration file (config.yaml).

Requirements

Gatling Commander is intended for use in load test with the Gatling Operator.
When using Gatling Commander, please create an environment in which the Gatling Operator can be used first. Information about how to setup Gatling Operator environment, please refer to the Gatling Operator Quick Start Guide.
