尝试执行云构建以将应用程序部署到云运行时出现错误

Question

我尝试将应用程序部署到云中运行的GCP，成功地使用docker file.Now执行，我使用cloudbuild.yaml .I镜像repo到CSR来设置CI/CD，并创建了一个cloudbuild服务，并将cloudbuild.yaml放在从cloudbuild执行的存储库.When中，它抛出了以下错误。

    Status: Downloaded newer image for gcr.io/google.com/cloudsdktool/cloud-sdk:latest
gcr.io/google.com/cloudsdktool/cloud-sdk:latest

Deploying...
Creating Revision...failed
Deployment failedERROR: (gcloud.run.deploy) Cloud Run error: Container failed to start. Failed to start and then listen on the port defined by the PORT environment variable. 

Docker文件附件如下：

#pulls python 3.7’s image from the docker hub
FROM python:alpine3.7
#copies the flask app into the container
COPY . /app
#sets the working directory
WORKDIR /app
#install each library written in requirements.txt
RUN pip install -r requirements.txt
#exposes port 8080
EXPOSE 8080
#Entrypoint and CMD together just execute the command
#python app.py which runs this file
ENTRYPOINT [ "python" ]
CMD [ "app.py" ]

cloudbuild.yaml：

 steps:
 # Build the container image
 - name: 'gcr.io/cloud-builders/docker'
   args: ['build', '-t', 'gcr.io/projectid/servicename', '.']
 # Push the container image to Container Registry
 - name: 'gcr.io/cloud-builders/docker'
   args: ['push', 'gcr.io/projectid/servicename']
 # Deploy container image to Cloud Run
 - name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'
   entrypoint: gcloud
   args:
   - 'run'
   - 'deploy'
   - 'phase-2'
   - '--image'
   - 'gcr.io/projectid/servicename'
   - '--region'
   - 'us-central1'
   - '--platform'
   - 'managed'
 images:
 - 'gcr.io/projectid/servicename'.  

Answer 1

OP解决了这个问题，如评论所示：

的问题是因为resolved.It的兼容性问题。我应该在docker文件中使用pip3和python3。我认为gcr.io镜像与python3兼容。
