# 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 ../
