oh-my-zsh installation returns non zero code

Question

I'm trying to install oh-my-zsh as part of a Docker build (using a Dockerfile). Here's the dockerfile line in question:

RUN wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh`

and the error I get is:

The command [/bin/sh -c wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh] returned a non-zero code: 1

Full error gist here

To debug, I've run the command manually and it works. Did anyone have luck installing oh-my-zsh as part of a docker build? any idea why it behaves differently if run this way?

Build failing because install.sh return non zero code, when you execute script manually you are ignoring return code, but docker failing build. Usually non-zero return code indicate error, but if in this case everything ok you could ignore this error:

RUN wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh || true
