I have a docker file and I want to install zsh/oh-my-zsh to I have like

FROM codercom/enterprise-base:ubuntu

when I run this image locally it works as expected and I can see a /home/coder/.oh-my-zsh folder created. When I use this from Coder, I don't get that folder created. What could be the issue?
