Gitlab CI/CD integration

Run your Gatling Enterprise simulations from GitLab CI/CD.

The Gatling Enterprise Docker runner

This runner, packaged as a Docker image and published on Docker Hub, enables you to start a Gatling Enterprise simulation directly from your GitLab CI/CD pipelines.

This plugin doesn’t create a new Gatling Enterprise simulation, you have to create it using the Gatling Enterprise Dashboard before.

On Gatling Enterprise Cloud, you can do it using the options provided by our build tools plugins:

Don’t forget to check out GitLab’s official documentation to learn how to write CI/CD pipelines on GitLab.

Docker Hub coordinates

The Docker image is published on Docker Hub with the following coordinates: gatlingcorp/enterprise-runner:1.

You can check out the latest releases available from the GitHub project. You generally only need to specify the major version you want to use, currently 1.

Pre-requisites

You must first create an API token. It will be used to authenticate with Gatling Enterprise.

You can store the API Token in a Gitlab CI Variable (make sure to check “Mask variable”) with the name GATLING_ENTERPRISE_API_TOKEN, which our tools will detect automatically. Or if you use a vault to store secrets, store the API Token in your vault and retrieve its value to an environment variable named GATLING_ENTERPRISE_API_TOKEN in your Gitlab CI/CD configuration file.

  • for Gatling Enterprise Cloud, the API token needs the Start permission.
  • for Gatling Enterprise Self-Hosted, the API token needs the All role.

We also assume that you have already configured a simulation on Gatling Enterprise. You can copy the simulation ID from the simulations list view. In the following examples, we will show the simulation ID as 00000000-0000-0000-0000-000000000000.

See Gatling Enterprise Cloud documentation or Gatling Enterprise Self-Hosted documentation.

Quickstart (minimal job configuration)

In this example, we configure a workflow which will only start a simulation as already configured and uploaded on Gatling Enterprise.

Create a file named .gitlab-ci.yml in your repository:

stages:
  - load-test

run-gatling-enterprise:
  stage: load-test
  image:
    name: gatlingcorp/enterprise-runner:1
    entrypoint: ['']
  script:
    - gatlingEnterpriseStart
  variables:
    # We assume GATLING_ENTERPRISE_API_TOKEN is available,
    # e.g. configured on the GitLab project
    # Specify your simulation ID:
    SIMULATION_ID: '00000000-0000-0000-0000-000000000000'
stages:
  - load-test

run-gatling-enterprise:
  stage: load-test
  image:
    name: gatlingcorp/enterprise-runner:1
    entrypoint: ['']
  script:
    - gatlingEnterpriseStart
  variables:
    # We assume GATLING_ENTERPRISE_API_TOKEN is available,
    # e.g. configured on the GitLab project
    # Specify the URL for your Gatling Enterprise Self-Hosted instance:
    GATLING_ENTERPRISE_URL: 'http://my-gatling-instance.my-domain.tld'
    # Specify your simulation ID:
    SIMULATION_ID: '00000000-0000-0000-0000-000000000000'

Push this to GitLab. The pipeline will run automatically on new commits; you can also run it manually from your GitLab project’s CI/CD menu.

Configuration reference

Several options can be configured with environment variables. The Docker runner also provides several outputs which you can export to access in the following stages of your pipeline.

  • GATLING_ENTERPRISE_API_TOKEN required: The API token used to authenticate with Gatling Enterprise.

  • SIMULATION_ID required: The ID of the simulation as configured on Gatling Enterprise.

  • EXTRA_SYSTEM_PROPERTIES optional: Additional Java system properties, will be merged with the simulation’s configured system properties. Must be formatted as a JSON object containing the desired key/value pairs. Values can be strings, numbers or booleans.

  • EXTRA_ENVIRONMENT_VARIABLES optional: Additional environment variables, will be merged with the simulation’s configured environment variables. Must be formatted as a JSON object containing the desired key/value pairs. Values can be strings, numbers or booleans.

  • OVERRIDE_LOAD_GENERATORS optional: Overrides the simulation’s load generators configuration. Must be formatted as a JSON object. Keys are the load generator IDs, which can be retrieved from the public API (using the /pools route). Weights are optional.

    See Gatling Enterprise Cloud public API documentation or Gatling Enterprise Self-Hosted public API documentation.

  • FAIL_ACTION_ON_RUN_FAILURE optional (defaults to true): If true, the Action will fail if the simulation run ends in an error (including failed assertions). Note: if set to false and the simulation ends in an error, some of the outputs may be missing (e.g. there will be no assertion results if the simulation crashed before the end).

  • WAIT_FOR_RUN_END optional (defaults to true): If true, the runner will wait for the end of te simulation run on Gatling Enterprise before terminating. Note: if set to false, some of the outputs may be missing (there will be no status nor assertion results).

  • OUTPUT_DOT_ENV_FILE_PATH optional (defaults to gatlingEnterprise.env): path to a dotenv file where output values will be written

  • RUN_SUMMARY_ENABLED optional (defaults to true): Assuming wait_for_run_end is also true, will regularly log a summary of the ongoing run to the console until it finishes. See also the logs section.

  • RUN_SUMMARY_INITIAL_REFRESH_INTERVAL optional (defaults to 5): Initial interval before displaying a new summary of the ongoing run in the console, in seconds. Should be a multiple of 5 (otherwise it will be rounded up). Only used a limited number of times (set by run_summary_initial_refresh_count) before switching to the interval set by run_summary_refresh_interval. See also the logs section.

Outputs

Outputs are written to a dotenv file, which can then be exported to make the variables available. Check out the GitLab documentation for more details on exporting dotenv files. Example:

stages:
  - load-test
  - post-load-test

run-gatling-enterprise:
  stage: load-test
  image:
    name: gatlingcorp/enterprise-runner:1
    entrypoint: ['']
  script:
    - gatlingEnterpriseStart
  variables:
    # For Gatling Enterprise Self-Hosted, you must specify the URL:
    # GATLING_ENTERPRISE_URL: 'http://my-gatling-instance.my-domain.tld'
    SIMULATION_ID: '00000000-0000-0000-0000-000000000000'
  artifacts:
    reports:
      dotenv: 'gatlingEnterprise.env' # Using the default value

print-output:
  stage: post-load-test
  image: alpine:latest
  script: |
    # Show that we can access the outputs exported by the previous stage
    echo "RUN_ID=$RUN_ID"
    echo "REPORTS_URL=$REPORTS_URL"
    echo "RUNS_URL=$RUNS_URL"
    echo "RUN_STATUS_CODE=$RUN_STATUS_CODE"
    echo "RUN_STATUS_NAME=$RUN_STATUS_NAME"
    echo "RUN_ASSERTIONS=$RUN_ASSERTIONS"    
  • RUN_ID: The ID of the run started by this runner.

  • REPORTS_URL: The URL of the reports page for this run.

  • RUNS_URL: The URL of the runs history page for this simulation.

  • RUN_STATUS_NAME: The name of the run’s final status (e.g. Successful, AssertionsSuccessful, AssertionsFailed, etc.).

  • RUN_STATUS_CODE: The code of the run’s final status.

  • RUN_ASSERTIONS: The results of the run’s assertions, as a JSON array.

Logs

Every few seconds, the Docker runner logs to the console output a summary of the run’s current status. When the run ends, it logs the status of the run and the results of any assertions. Here’s the beginning and end of a very short duration example:

A run's logs in the GitLab CI/CD console (beginning)
A run's logs in the GitLab CI/CD console (end)

By default, logs are printed every 5 seconds the first 12 times (i.e. during 60 seconds), then every 60 seconds. This can be adjusted using the input variables RUN_SUMMARY_INITIAL_REFRESH_INTERVAL, RUN_SUMMARY_INITIAL_REFRESH_COUNT, and RUN_SUMMARY_REFRESH_INTERVAL. The ongoing logs can also be completely disabled using the input variable RUN_SUMMARY_ENABLED: 'false': in this case, only the final results will be printed.

Sample use cases for cloud Cloud

Build and run simulation

This pipeline is defined in the GitLab repository which contains your Gatling simulation script built with one of our build tools plugins. In this example, every time the code on the main branch gets updated, we:

  • build, package, and upload to Gatling Enterprise the current version of the simulation script
  • run the updated simulation on Gatling Enterprise

Feel free to use different workflow rules or to configure the other inputs and outputs for the runner as documented above, according to your own use case.

Sample use cases Self-Hosted

Building from sources

In this example, we assume you have configured your repository on Gatling Enterprise to build from sources, from your GitHub repository’s main branch. Every time the code on the main branch gets updated, we run the updated simulation on Gatling Enterprise.

Feel free to use different trigger events or to configure the other inputs and outputs for the runner as documented above, according to your own use case. But keep in mind that Gatling Enterprise will only download and run your simulation scripts from the branch set in the simulation configuration!

workflow:
  rules:
    # Execute the pipeline only on pushes to the main branch
    - if: $CI_COMMIT_BRANCH == "main"

stages:
  - load-test

# Run the simulation on Gatling Enterprise
# If it is configured to "build from sources" from the branch "main",
# it will download and run the updated version of the code
run-gatling-enterprise:
  stage: load-test
  image:
    name: gatlingcorp/enterprise-runner:1
    entrypoint: ['']
  script:
    - gatlingEnterpriseStart
  variables:
    GATLING_ENTERPRISE_URL: 'http://my-gatling-instance.my-domain.tld'
    SIMULATION_ID: '00000000-0000-0000-0000-000000000000'

Using a binary repository

This workflow is defined in the GitLab repository which contains your Gatling simulation script built with one of our build tools plugins. In this example, every time the code on the main branch gets updated, we build, package, and publish the current version of the simulation script, before starting the simulation on Gatling Enterprise.

In this example, we assume that:

  • You have configured your repository on Gatling Enterprise to download from a binary repository, using Artifactory or Sonatype Nexus.
  • You have configured your simulation to use the version marker latest.integration for the artifact published on the binary repository.
  • Your build is properly configured to publish to the binary repository, using Maven, Gradle, or sbt.
