Error when running docker build

[forest]

I'm getting an error when trying to build my image based on this one. I have a very simple Phoenix app and followed your blog post minus the docker-compose stuff. I don't need the DB.

Here is the output from my run:

❯ docker build -t my-phoenix-app . 
Sending build context to Docker daemon 526.3 kB
Step 1 : FROM shanesveller/phoenix-framework:latest
# Executing 7 build triggers...
Step 1 : WORKDIR /usr/src/app
 ---> Using cache
Step 1 : COPY *.js* /usr/src/app/
stat Dockerfile: no such file or directory

This is probably my issue but I can't figure it out.
