containerd/contrib/Dockerfile.test

# This dockerfile is used to test containerd within a container
#
# usage:
# 1.) docker build -t containerd-test -f Dockerfile.test ../
# 2.) docker run -it --privileged -v /tmp:/tmp --tmpfs /var/lib/containerd-test containerd-test  bash
# 3.) $ make binaries install test
#
# Use the RUNC_VERSION build-arg to build with a custom version of runc, for example,
# to build runc v1.0.0-rc94, use:
#
# docker build -t containerd-test --build-arg RUNC_VERSION=v1.0.0-rc94 -f Dockerfile.test ../

# cri-in-userns stage is for testing "CRI-in-UserNS", which should be used in conjunction with
# "Kubelet-in-UserNS": https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/2033-kubelet-in-userns-aka-rootless
# This feature is mostly expected to be used for `kind` and `minikube`.
#
# Requires Rootless Docker/Podman/nerdctl with cgroup v2 delegation: https://rootlesscontaine.rs/getting-started/common/cgroup2/
# (Rootless Docker/Podman/nerdctl prepares the UserNS, so we do not need to create UserNS by ourselves)
