Basically I have an app that calls a web browser for authentication purposes

Any help is appreciated

Thanks

I can do this with a Dockerfile along the lines of (Please note I have found most of the code for this from other repos), but would like to add a web access etc for this

FROM ubuntu:bionic

RUN useradd apps
RUN mkdir -p /home/apps && chown apps:apps /home/apps

RUN apt-get install -y xvfb

The main focus of this baseimage is to run a single application. However, I guess you could install Chrome along with your app and launch it manually when needed. If your app invokes xdg-open to open an URL, you can create a script at /usr/bin/xdg-open and launch Chrome from there.

Else, you can have a look at https://github.com/fcwu/docker-ubuntu-vnc-desktop for a full desktop.
