$PATH is not passed

[prary]

Actual behavior
Dockerfile

FROM something/lrh7
RUN env

Do a docker build, output shows

Step 2/3 : RUN env
 ---> Running in a7ea3e88b5a6

HOSTNAME=a7ea3e88b5a6
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
PWD=/
SHLVL=1
HOME=/root
_=/usr/bin/env

Do skaffold build -v=debug

INFO[0025] RUN env
INFO[0025] cmd: /bin/sh
INFO[0025] args: [-c env]
PWD=/

Expected behavior
Path variable should be retained

[tejal29]

can you try

docker run -it something/lrh7  env

and see if the PATH variable is set?

[prary]

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
HOSTNAME=34fbfd2c2006
TERM=xterm
HOME=/root

If we do echo $PATH then

INFO[0021] RUN echo $PATH
INFO[0021] cmd: /bin/sh
INFO[0021] args: [-c echo $PATH]
/usr/local/bin:/usr/bin

Don't know from where this $PATH is coming

We should set the default path if $PATH isnt defined in base image

kaniko/pkg/executor/build.go

Line 127 in 1d3cf8a

if img == empty.Image {

Should remove this condition
