iter8 k launch
iter8 k launch¶
Launch an experiment inside a Kubernetes cluster
Synopsis¶
Launch an experiment inside a Kubernetes cluster.
iter8 k launch --set "tasks={http}" --set http.url=https://httpbin.org/get \
--set runner=job
Use the dry option to simulate a Kubernetes experiment. This creates the manifest.yaml file, but does not run the experiment, and does not deploy any experiment resource objects in the cluster.
iter8 k launch \
--set http.url=https://httpbin.org/get \
--set runner=job \
--dry
The launch command creates the 'charts' subdirectory under the current working directory, downloads the Iter8 experiment chart, and places it under 'charts'. This behavior can be controlled using various launch flags.
This command supports setting values using the same mechanisms as in Helm. Please see https://helm.sh/docs/chart_template_guide/values_files/ for more detailed descriptions. In particular, this command supports the --set, --set-file, --set-string, and -f (--values) options all of which have the same behavior as in Helm.
