Tilt CLI Reference

tilt demo

Creates a local, temporary Kubernetes cluster and runs a Tilt sample project


Test out Tilt using an isolated, ephemeral local Kubernetes setup.

Tilt will create a temporary, local Kubernetes development cluster running in Docker. The cluster will be removed when Tilt is exited with Ctrl-C.

A sample project (github.com/tilt-dev/tilt-avatars) will be cloned locally to a temporary directory using Git and launched.
