ctr-powertest - Container runtime test tool

Easy and extensible tool for any OCI supported container runtime.

Useful to run same testcases on supported runtimes.

Currently supports

  • containerd
    • Status : WIP
      • Containerd support is 80% completed.
  • k8s CRI
    • Any runtime that implementes Kubernetes Container Runtime Interface
    • Tested for cri-containerd & cri-o
    • Status : WIP
      • CRI support is 60% completed.

Usage:

ctr-powertest -p <protocol> [-r <runtime>] <test-cases> [flags] [args]

Usage Example:

ctr-powertest -p cri -r cri-containerd stress -t image-pull

  -d, --debug            debug mode
  -p, --proto string     Protocol [ containerd, cri ] (default "containerd")
  -r, --runtime string   CRI-Runtime [ cri-containerd, crio ] (default "cri-containerd")

Performace:

Running performance test

Performace test can be directly run on system by running following commands

it build and run crio & cri-containerd in docker container (original idea cri-containerd-flame)

make crio
make cri-containerd

Perfomance

  • All using same runc version

Important TODO:

  • Implement Exec interface for CRI and containerd.
  • Implement Wait & Kill for CRI
