Hi! I tried your fly.yml and it worked for me.

One difference I could find in your fly.toml was that I got this line

[build]
  dockerfile = "Dockerfile"

Maybe that will help

Also, my Dockerfile also looks different, but I'm running a Django app.

ARG PYTHON_VERSION=3.10-slim-buster
FROM python:${PYTHON_VERSION}
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
RUN mkdir -p /code
WORKDIR /code
COPY requirements.txt /tmp/requirements.txt
RUN set -ex && \
    pip install --upgrade pip && \
    pip install -r /tmp/requirements.txt && \
    rm -rf /root/.cache/
COPY . /code/
RUN python ./manage.py collectstatic
EXPOSE 8000
CMD ["gunicorn", "--bind", ":8000", "--workers", "2", "mysite.wsgi"]

Can you deploy it from your own computer?

[eliasj]

Ohh, I missed one thing. I added --remote-only on the last line in fly.yml, so it looks like this: flyctl deploy --remote-only. All the docs got it.

Hi @eliasj , thank you for the reply. Yes, I could deploy it with my own Windows 10 PC and flyctl deploy --local-only command, but flyctl deploy --remote-only command on my PC always stuck on

Waiting for remote builder

That's why I want to try to deploy it with GitHub Actions.

After adding

[build]
  dockerfile = "Dockerfile"

and --remote-only in the specified files, it still fails with the similar error message.

Can you please share more about your fly.yml file?

[mingchau]

Finally, I found the problem was caused by the .dockerignore file, which was auto-generated, so I've assumed it's ok.😅

There is error log which I ignored says:

time="**" level=error msg="Error matching .dockerignore: syntax error in pattern"

Replacing the \ with / in the .dockerignore file, everything goes good!

Are you running on a Windows machine? Just for reference, if someone gets this error in the future.

Sorry, I made a typo in the previous reply, it should be the .dockerignore file, not the .gitignore file. I have edited it. Yes, I am using a Windows PC. The file was generated by flyctl.
