how to make img for ranchervm?

[ruanshudong]

in example , docker was created like this:
[root@mirror centos]# make build
docker build --build-arg BASE_IMAGE=centos7.0.qcow2 -t rancher/vm-centos:1 .
Sending build context to Docker daemon 4.296GB
Step 1/3 : FROM scratch
--->
Step 2/3 : ARG BASE_IMAGE
---> Using cache
---> b8fd05b49a47
Step 3/3 : COPY ${BASE_IMAGE} /base_image/${BASE_IMAGE}
---> d0ffb95143d7
Successfully built d0ffb95143d7
Successfully tagged rancher/vm-centos:1
[root@mirror centos]# ls
centos7.0.qcow2 Dockerfile Makefile
[root@mirror centos]# cat Dockerfile
FROM scratch
ARG BASE_IMAGE
COPY ${BASE_IMAGE} /base_image/${BASE_IMAGE}

i create img, k8s pull the docker file failed, kubectl describe pod pull-centos-1-172.16.124.203:

Error: failed to start container "pull": Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: "/bin/sh": stat /bin/sh: no such file or directory": unknown

Should i modify Dockerfile to this?
FROM rancher/vm-base
ARG BASE_IMAGE
COPY ${BASE_IMAGE} /base_image/${BASE_IMAGE}

Try

FROM alpine

instead of scratch

I modify Dockerfile to:
FROM rancher/vm-base

it seems work fine!
