kpm, the Kubernetes Package Manager

kpm is a package manager for Kubernetes. It is designed to be a simple CLI for managing Kubernetes-native application packaging.

To begin, it focuses on OLM's registry+v1 bundle format, but the intention is to expand it to support more (FBC, Helm, and other Kubernetes-native application artifacts)

Installation

go install github.com/operator-framework/kpm@latest

OLM registry+v1 bundles

1. Build the bundle into a kpm file:

   $ cat << EOF > bundle.kpmspec.yaml
   apiVersion: specs.kpm.io/v1alpha1
   kind: RegistryV1
   
   source:
     sourceType: BundleDirectory
     bundleDirectory:
       path: ./bundle
   EOF
   
   $ kpm build ./bundle.kpmspec.yaml
   Bundle my-operator.v0.1.0 written to my-operator.v0.1.0.kpm (digest: sha256:ebd8006b0bee0e1b0b26b313b21213229c436498a6ad023d3bbb561abfccb815)

2. Push the kpm file to an image registry:

   $ skopeo copy oci-archive:./my-operator.v0.1.0.kpm docker://quay.io/my-org/my-operator:v0.1.0
