HelloBench is originally authored by @tylerharter. The original repository is not active for quite a long time. I forked the repository from commit 0fa7a8c7950615cb5aae04a85226f04f88ad3bda. As Python2 had reached its EOL, hello-bench adapts Python3 to attract more young python developers.

Nowadays, several container image acceleration solutions around containerd and CRI-O/podman are being introduced. This forked project is aiming at building a universal container startup benchmark tool. Acceleration images usually differs OCI images by image tags. So the improved hello-bench can receive image tags now.

This repository just contains the benchmark harness than runs various Docker, OCI and other acceleration container images e.g. nydus and stargz.

Please ensure your nerdctl is beyond v0.22

Both docker and containerd can manage container images. Containerd has more a flexible mechanism - snapshots - to add plugin and manage containers images. To run benchmark for different container engines, change hello-bench argument --engine.

• docker for Docker
• nerdctl for Containerd

./hello.py --engine nerdctl --op run --images python:3.7
./hello.py --engine docker --op run --images python:3.7

# To run benchmark for nydus snapshotter.
./hello.py --engine nerdctl --snapshotter nydus --op run --registry=gechangwei --images python:3.7-nydus
