NOTE: This project is a work in progress

The CLI for developing, collaborating, and delivering data-centric applications.

Install Instructions

go install


KMDR is the CLI for kubelt but, KMDR also works in offline contexts.

KMDR provides a kubernetes-like experience for defining a schema driven graph of data containers, a git-like experience for working with data against those data containers, and a package manager-like experience for materializing/synthensizing datasets and running transforms. With KMDR, users can discover, source, publish and subscribe to data to collaborate with peers across the globe.


kubelt is a distrubuted platform that operates on an IPFS data plane. The tools kubelt publishes provides users with a familiar developer experience and abstractions for working with datasets and data pipelines.

The KMDR CLI is paired with a daemon named KTRL and as the names suggest, KMDR instructs KTRL to perform specific actions using declarative manifests. KTRL manages an offline IPFS node, auth, and more (for more details checkout the KTRL repo).

Some further concepts are below.


KMDR uses declarative configurations to apply changes to the underlying graph and linked data. These declartive configrations can be supplied to KMDR as manifests written in (cue)[].

TODO: provide examples

Graph and Content Addresses

kubelt maintains a graph of data containers that define users, datasets, and more. The graph informs KMDR and KTRL the metadata and addresses for data stored in the data plane.


Information stored on the data plane is encrypted into opaque blocks of data chuncked based on the schema provided by the user.

Types and Schemas

KMDR encourges defining types and schemas for your datasets in order to optimize the utility of the underlying platforms.

Schemas help KMDR reason about your data to validate it, clean it, share it, materalize it, synthesize it, and otherwise improve it.

TODO: provide examples

Immutability and Versioning

All data published to a specific content address is immutably stored in a directed acyclic graph. Just like with git, changes can be rolled back leaving unwanted changes in a detached state.


Similar to Kubernetes contexts, KMDR supports multiple contexts and contexts are linked to specific enviroments.

Offline only contexts are currently supported however, online public, managed, and on-prem backed contexts will be rolled out over time.
