Examples of Node-to-Node image sharing on Kubernetes using nerdctl ipfs registry

This directory contains examples of node-to-node image sharing on Kubernetes with nerdctl ipfs registry.

  • ./ipfs: node-to-node image sharing using IPFS
  • ./ipfs-cluster: node-to-node image sharing with content replication using ipfs-cluster
  • ./ipfs-stargz-snapshotter: node-to-node image sharing with lazy pulling using eStargz and Stargz Snapshotter

Example Dockerfile of nerdctl ipfs registry

The above examples use nerdctl ipfs registry running in a Pod. The image is available at ghcr.io/stargz-containers/nerdctl-ipfs-registry.

The following Dockerfile can be used to build it by yourself.
