We’re using GCP Cloud Build to build and push container images upon any merge activities to main branch in GitHub. In the 2nd step of CloudBuild, we run into the issue COPY failed: file not found in build context or excluded by .dockerignore: stat requirements.txt: file does not exist.

I ran docker build . under the root directory where both Dockerfile and requirements.txt are located.

The directory looks like this:

• Dockerfile
• requirements.txt
• deploy
  • cloudbuild.yaml
  • deployment.yaml

Dockerfile:

# Use the official lightweight Python image.
# https://hub.docker.com/_/python
FROM python:3.10.12-slim


# Allow statements and log messages to immediately appear in the Knative logs
ENV PYTHONUNBUFFERED True

# Copy local code to the container image.
ENV APP_HOME /app
WORKDIR $APP_HOME
ENV PYTHONPATH /app


# Install production dependencies.
COPY requirements.txt ./requirements.txt
COPY . .
RUN pip install --no-cache-dir -r requirements.txt

CMD ["python3", "telegram_bot.py"]

This is the cloudbuild.yaml:

steps:
  - name: 'gcr.io/cloud-builders/git'
    entrypoint: 'bash'
    args:
      - '-c'
      - |
        git clone https://[email protected]/CohumanSpace/cohuman.git
        cd cohuman
        git checkout .
    secretEnv: ['GH_TOKEN']

  - name: 'gcr.io/cloud-builders/docker'
    args: ['build', "--no-cache", '-t', 'gcr.io/cohuman-432919/telegram-bot:$SHORT_SHA', '-f', '../Dockerfile', '.']
    dir: 'deploy'

logsBucket: gs://gke-deployment/

images:
  - 'gcr.io/cohuman-432919/telegram-bot:$SHORT_SHA'

availableSecrets:
  secretManager:
    - versionName: projects/cohuman-432919/secrets/GH_TOKEN/versions/latest
      env: 'GH_TOKEN'

I tried:

1. RUN cwd: it prints out “/app” in Cloud Build logs.
2. RUN ls: nothing.
3. I looked thru almost all online posts and forums I can find and most mention that the copied files shouldn’t be in .dockerignore and the copied files should under the same directory as Dockerfile. My setup is correct to these 2 points.
