Your First Experiment¶
Get started with your first Iter8 experiment by benchmarking an HTTP service.
1. Install Iter8 CLI¶
Install the latest stable release of the Iter8 CLI using
brew as follows.
brew tap iter8-tools/iter8 brew install firstname.lastname@example.org

2. Launch experiment¶
iter8 launch to benchmark the HTTP service whose URL is https://httpbin.org/get.
iter8 launch -c load-test-http --set url=https://httpbin.org/get --set numRequests=40
iter8 launch command downloads Iter8 experiment charts, combines a specified chart (
load-test-http in the above instance) with various parameter values (
numRequests in the above instance), generates the
experiment.yaml file, runs the experiment, and writes results into the
3. View experiment report¶
The text report looks like this
