CNAB Operator

🚨 This repository has been archived. Our operator efforts are being continued in https://github.com/getporter/operator 🚨

Running locally

Prerequisites

• operator-sdk
• dep version v0.5.0+.
• git
• go version v1.10+.
• docker version 17.03+.
• kubectl version v1.11.3+.
• Access to a Kubernetes v1.11.3+ cluster.

Building and running

For now, you can run a local OCI registry, push a CNAB bundle using a tool that implements the coras package (coras or this branch of duffle).

You must first create the Custom Resource Definition for a CNAB Bundle (this is a placeholder that only contain the name and URL you can find the bundle in an OCI registry), then create an instance of the Bundle CRD with the remote bundle you pushed. At this point, the controller will pull the bundle periodically and, for now, display it.
