shell.image in 0.14.x has problems

[skaegi]

I noticed this when running under Kata but I believe this is a general problem with anyone using "scripts" in Tasks.

For "kata" in the container logs I was seeing...

standard_init_linux.go:211: exec user process caused "exec format error"
ERRO[0000] init failed                                   error="standard_init_linux.go:211: exec user process caused \"exec format error\"" name=kata-agent pid=1 source=agent

for any shell script run using the place-scripts container.

Running docker locally...

With 0.14.x shell.image
$ docker run --rm gcr.io/distroless/base@sha256:f79e093f9ba639c957ee857b1ad57ae5046c328998bf8f72b30081db4d8edbe4 -c ls
ls: can't open '.': Value too large for defined data type

With latest distroless base debug
$ docker run --rm gcr.io/distroless/base:debug -c ls
bin
boot
busybox
dev
etc
home
lib
lib64
proc
root
run
sbin
sys
tmp
usr
var

We should probably update shell.image to use the current gcr.io/distroless/base:debug SHA
e.g. gcr.io/distroless/base@sha256:60f5ffe6fc481e9102747b043b3873a01893a5a8138f970c5f5fc06fb7494656

Anyone running with gVisor will also have this problem... GoogleContainerTools/distroless#352
