xk6-pubsub

This is a k6 extension using the xk6 system.

:exclamation: This is a proof of concept, isn’t supported by the k6 team, and may break in the future. USE AT YOUR OWN RISK!

Build

To build a k6 binary with this extension, first ensure you have the prerequisites:

  1. Install xk6 framework for extending k6:

    1. go install github.com/k6io/xk6/cmd/xk6@latest

  2. Build the binary:

    1. #Required by Pub/Sub client
    2. export CGO_ENABLED=1
    1. xk6 build --with github.com/olvod/xk6-pubsub@latest

xk6 build —with github.com/k6io/xk6-redis=”/Users/avpretty/pr/xk6-pubsub”

  1. Setup Google Pub/Sub configuration via environment variables:
    1. export PUBSUB_PROJECT_ID=<project_id>
    2. export PUBSUB_CREDENTIALS=<credentials>

Or use PubSub emulator for local development
PUBSUB_EMULATOR_HOST environment variable must be present.

  1. export PUBSUB_EMULATOR_HOST=<emulator_host>

  1. ./k6 run example.js
