Build Status GoDoc


Tilt is a toolkit for building multi-service dev environments.

Tilt offers many first-party data types like Docker builds and Kubernetes appliers. But long-term, we want to make it easier for users to define their own data types and behaviors.

The future of Tilt is a simple model consisting of very few types of building blocks, and a mix of uniformity and versatility whereby using the same simple elements one can build complex systems and different types of functionality.

The Tilt apiserver is the base layer of that model.


The Tilt apiserver is a full-fledged Kubernetes API server. You can query it with kubectl or any standard Kubernetes tooling.

This repo offers:

  • A builder for registering data types, storing them in memory, and serving them up on any port on HTTP
  • An example data type
  • An example of generated client code

This repo is intended primarily for consumption by, where we define the first-party data types and controllers that Tilt needs.


To develop the API server, install Tilt and run:

tilt up

This will present you with a list of common commands we run in development.

You may prefer running commands in the terminal.

To run on port 9443:

make run-apiserver

To create a new data object:

kubectl --kubeconfig kubeconfig apply -f manifest.yaml


Big thanks to the Kubernetes community for all the help and documentation on how to use their API infrastructure. We could not have built this without inspiration from:
