I have created an image to run docker container with chrome. Below is my code. My dockerfile does compile into image. But whenever I try to run container from image I get error "Bootstrap.sh file not found" Although file is present in my FileSystem snapshot inside image. You can check screenshot.
Please help me resolve this issue I am new to docker.

Proof bootstrap.sh file is present inside my docker image
What you need to do is give the file the correct permissions. In your Dockerfile if you can add the line RUN chmod +x /bootstrap.sh
right before you run CMD.
Dockerfile
FROM ubuntu:16.04
COPY bootstrap.sh /
RUN apt-get update && apt-get clean && apt-get install -y \
x11vnc \
xvfb \
fluxbox \
wmctrl \
wget \

&& echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list \

RUN useradd apps \

You can try this: CMD sh /bootstrap.sh
