Docker file does not have /bin/bash directory

I have been following this tutorial about posting a Rasa chatbot on Heroku using a Docker image. I am using Windows 10, and I am new to Docker.

When I get to the step heroku container:push web -a {appname}, it runs through the Dockerfile, but it outputs the following error:

container_linux.go:380: starting container process caused: exec: "/bin/bash": stat /bin/bash: no such file or directory

I've tried doing some of the suggestions in other StackOverflow responses like, such as updating ubuntu, installing bash (with apt-get and apk), adding different shebangs. However, I can't seem to get the Dockerfile to run chmod or any similar commands. Here is my Dockerfile for reference.

FROM ubuntu
RUN apt-get update -y
RUN apt-get install -y bash

FROM rasa/rasa:latest
ADD . /testheroku/
RUN chmod +x /testheroku/rasa.sh
RUN cd /testheroku && rasa train
ENTRYPOINT []
CMD /testheroku/rasa.sh

The terminal shows the following process as it builds:

[+] Building 0.8s (7/8)
=> [internal] load build definition from Dockerfile <br
=> => transferring dockerfile: 32B
=> [internal] load .dockerignore
=> => transferring context: 2B
=> [internal] load metadata for docker.io/rasa/rasa:latest
=> [internal] load build context
=> => transferring context: 721B
=> [stage-1 1/4] FROM docker.io/rasa/rasa:latest
=> CACHED [stage-1 2/4] ADD . /testheroku/
=> ERROR [stage-1 3/4] RUN chmod +x /testheroku/rasa.sh

Does anyone have any thoughts about what I need to do to make this run?

Why are you using #! /usr/bin/env bash in your Dockerfile?

Did you try building your image without that line?

Your Dockerfile should look just like this:

FROM ubuntu
RUN apt-get update -y
RUN apt-get install -y bash

FROM rasa/rasa:latest
ADD . /testheroku/
RUN chmod +x /testheroku/rasa.sh
RUN cd /testheroku && rasa train
ENTRYPOINT []
CMD /testheroku/rasa.sh
