谷歌云构建错误：构建步骤 0“gcr.io/cloud-builders/docker”失败：步骤以非零状态退出：1

Question

Note: There is a similar post regarding this issue but it involves a CI/CD workflow and a considerably more complicated Dockerfile. The solutions presented do not seem to apply to my situation.

Per Google documentation I am attempting to build an image by running gcloud run deploy in the directory where the files mentioned in my Dockerfile are located. The Dockerfile appears as:

FROM python:3.9-alpine
WORKDIR /app
COPY main.py /app/main.py
COPY requirements.txt /tmp/requirements.txt
RUN pip3 install -r /tmp/requirements.txt
CMD ["python3", "main.py"]

I receive a message that the build failed, and when checking the logs I see the following:

starting build "..."

Can anyone explain the reason for this error? I suspect it has to do with how files are copied to the image, but I was able to build and run this container without problem on my local machine. Any idea why this fails in Cloud Run Build?

Running ls -la in the directory where I ran gcloud run deploy returns:

Answer 1

I had added Dockerfile to .gitignore as it contained API keys stored as environment variables. Removing Dockerfile from .gitignore resolved the issue.
