Not able to execute any sudo commands in Jenkins

Question

Im trying to run my pipeline through Jenkins and not able to execute any commands using "sudo". Getting the following error when sudo is encountered :

sudo: you do not exist in the passwd database

Follwing the Dockerfile which Im using for setting up the Jenkins slave.
