I think this would be a question other than an issue.

I plan to use kubernetes plugin to run my jobs. Because I need to run python, I build a new image based on jnlp-slave then install python and related packages. After running on slave I found that the slave node can hardly recognize any python command. I also use

Building remotely on jenkins-slave-zcrgk (jenkins-slave) in workspace /home/jenkins/workspace/test
[test] $ /bin/sh -xe /tmp/jenkins7218841966279036340.sh

cd /usr/bin
ls -la

to list all the command, python is not in there. But If I run this slave image at my local machine
docker run -it --rm --entrypoint /bin/bash --user root robinchen007/jenkins-slave:1.5
python interpreter works well.
Can you help to figure out the reason?
