Trying pre-converted images

We have several pre-converted stargz images on Github Container Registry (ghcr.io/stargz-containers), mainly for benchmarking purpose. This document lists them.

ℹ️ You can build eStargz from Dockerfile using BuildKit, using Docker Buildx or Kaniko.

ℹ️ You can convert arbitrary images into eStargz optimized for your workload, using ctr-remote command.

ℹ️ You can convert arbitrary images into eStargz on the registry-side, using estargz.kontain.me.

Pre-converted images

ℹ️ You can request new pre-converted images from our CI repository (github.com/stargz-containers/image-ci).

In the following table, image names listed in Image Name contain the following suffixes based on the type of the image.

  • org: Legacy image copied from docker.io/library without optimization. Layers are normal tarballs.
  • esgz: eStargz-formatted version of the org images. ctr-remote images optimize command is used for the optimization.

Optimized Workload column describes workloads used for building esgz images. We optimized these images for benchmarking which is based on HelloBench so we specified "hello-world"-like workloads for the command. See benchmarking script for the exact command option specified for ctr-remote images optimize.

lazy-pulling-enabled KinD node image

You can enable lazy pulling of eStargz on KinD using our prebuilt node image ghcr.io/containerd/stargz-snapshotter:${VERSION}-kind namespace.

Example:

$ kind create cluster --name stargz-demo --image ghcr.io/containerd/stargz-snapshotter:0.12.1-kind

Please refer to README for more details.
