Bundle. Declare. Reconcile.
Kubo facilitates the bundling, installing, and managing of container-native applications — and their coupled services — on Kubernetes. One versioned, portable deliverable. No vendor lock-in.
A Stack is the unit of delivery
A Stack is a cloud-native application bundle: an OCI artifact that packages Helm charts, images, and values into a single, versioned, portable deliverable — composable across teams, organizations, and registries.
Package once
Charts and images are packaged into a single OCI artifact, versioned like any other image and pushed to the registry of your choice.
make bundle
Declare intent
A Stack CRD points at the bundle and declares components, dependencies, and values — the whole product as one declarative object.
kind: Stack
Let the operator drive
The controller installs components in dependency order via Helm, prunes dropped releases, and reports per-component status — continuously.
status.phase: Ready
Installed once, watching every Stack
Cluster-scoped operators are installed once in a shared operators namespace and watch every tenant namespace — tenant charts never duplicate them. Enable only what your product needs, per Stack.
From clone to Stack in four commands
Requires Go 1.23+, Docker, kubectl, and access to a Kubernetes cluster.
