gcloud 崩溃（OSError）：[Errno 2] 没有这样的文件或目录：'/workspace/env/bin/python3.7'

Question

尝试部署我的 fastapi python 服务（在 App Engine 上）时，我运行在部署步骤中遇到以下错误：ERROR: gcloud crashed (OSError): [Errno 2] No such file or directory: '/workspace/env/bin/python3.7'

我正在使用以下命令从我的本地计算机启动 deploy/build：gcloud builds submit --config config/cloudbuild/deploy.yaml --project $_PROJECT。

是我做错了什么，还是gcloud builder出了问题？我已经尝试使用 google cloud sdk 版本 274.0.1 和 300.0.0.

deploy.yaml:

steps:

  # Install gcc
  - name: 'python:3.7'
    id: 'install-dependencies'
    entrypoint: sh
    args:
      - -c
      - apt update && apt-get -y install gcc && python -m pip install -r requirements.txt -t lib

  # Run tests
  - name: 'python:3.7'
    id: 'test'
    env:
      - PYTHONPATH=lib
    entrypoint: python3
    args: ['-m', 'pytest']

  # Deploy
  - name: 'gcr.io/cloud-builders/gcloud'
    args: ['app', 'deploy', '--project', '$PROJECT_ID']

timeout: '1200s'

app.yaml:

runtime: python37
service: my-service
instance_class: F2

entrypoint: gunicorn main:app -w 4 -k uvicorn.workers.UvicornWorker
handlers:
  - url: /.*
    script: auto
    secure: always

inbound_services:
- warmup

automatic_scaling:
  min_instances: 1
  min_idle_instances: 1
  max_instances: 2
  max_idle_instances: 1

构建输出：

Cloud Build 本质上是一个应用于共享文件系统 (/workspace) 的容器管道。

您唯一可用的状态是通过 /workspace。

每一步都隐式挂载 /workspace。

您的第 0 步大部分是多余的。它将 apt 应用于步骤 #0 中创建的容器映像（并且可能作为副作用）也会更新已安装的 /workspace 但这些更新将被丢弃（除了 /workspace 的突变该步骤完成。您不应尝试使用例如您打算在后续步骤中使用的 Python 模块安装来更新 /workspace。

我怀疑您正在安装 pytest 和步骤 #0 中的 requirements.txt 但这并不正确地适用于步骤 #1 对 pytest 的使用。您应该做的是创建一个包含 pytest 的容器，以便您可以运行 pytest 在此步骤中。

如果您放弃除第 2 步以外的所有内容，它应该会起作用（对我来说是这样）。

如果您希望运行 pytest，您将需要一个包含它的容器映像，以便您可以运行在部署之前执行此独立步骤。
