Load Test for HTC

Overview

This is a general purpose gRPC load test.

See the details of running the program in its src/README.md.

Deploy with Terraform

Requirements

You must have have the following installed:

Note that Cloud Shell meets the requirements.

Configuration

Create terraform.tfvars with the following content:

project_id="<project id>"
region="<region>"
zones=["<letter zone1>", "<letter zone2>", "<letter zone3>"]

For example in us-central1:

project_id="<project id>"
region="us-central1"
zones=["a", "b", "c", "f"]

For example in europe-west1:

project_id="<project id>"
region="europe-west1"
zones=["b", "c", "d"]

Create infrastructure

Authorize gcloud if needed:

gcloud auth login  --quiet --update-adc

You may need to enable some basic APIs for Terraform to work:

gcloud services enable iam.googleapis.com cloudresourcemanager.googleapis.com

Initialize and run terraform:

terraform init
terraform apply

NOTE: While running the terraform if the APIs are newly enabled, there may be timing errors and terraform apply will need to be re-run.

Seeing infrastructure & Running Test Workloads

See what's from terraform

Inspect the possible run scripts:

terraform output

Key variable outputs:

  • local_test_scripts contain a list of shell scripts which you can run for different loadtests.
  • get_credentials is the command line to fetch the credentials for kubectl.
  • lookerstudio_create_dashboard_url is a link to create a new Lookerstudio Dashboard from a template.
  • monitoring_dashboard_url is a custom made monitoring dashboard for loadtest.

Running the GUI

Create a virtual environment:

python3 -m venv ui/.venv
ui/.venv/bin/python3 -m pip install --require-hashes -r ui/requirements.txt

Run the Gradio dashboard:

ui/.venv/bin/python3 ui/main.py generated/config.yaml

Use port 8080 or preview 8080 in the Cloud Shell (Webpreview). This allows you to load tests, inspect the jobs from BigQuery (similar to the dashboard), and has some deep links into the Console.
