复制失败:stat /var/lib/docker/tmp/docker-builder<num>/server/requirements.txt:没有这样的文件或目录

似乎是某种上下文问题。我试图弄清楚为什么在使用 Skaffold 启动本地 Kubernetes 集群时效果很好,但在推送到 Azure 时却无法正确构建映像。

基本结构是:

test-app/
  server/
    requirements.txt
    Dockerfile
azure-pipeline.yml
skaffold.yaml

我的制作server/Dockerfile如下:

FROM python:3.7-slim
ENV PYTHONUNBUFFERED 1
WORKDIR '/app'
EXPOSE 5000
COPY ./server/requirements.txt .
RUN pip install -r requirements.txt
COPY ./server .
CMD ["python", "manage.py", "collectstatic"]
CMD ["gunicorn", "-b", ":5000", "--log-level", "info", "config.wsgi:application"]

我正在使用azure-pipelines.yml在 Azure DevOps 的 Pipelines 部分中为我生成的:

# Docker
# Build and push an image to Azure Container Registry
# https://learn.microsoft.com/azure/devops/pipelines/languages/docker

trigger:
- master

resources:
- repo: self

variables:
  # Container registry service connection established during pipeline creation
  dockerRegistryServiceConnection: '<connection-string>'
  imageRepository: 'testapp'
  containerRegistry: 'testappcontainers.azurecr.io'
  dockerfilePath: '$(Build.SourcesDirectory)/server/Dockerfile'
  tag: '$(Build.BuildId)'

  # Agent VM image name
  vmImageName: 'ubuntu-latest'

stages:
- stage: Build
  displayName: Build and push stage
  jobs:  
  - job: Build
    displayName: Build
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: Docker@2
      displayName: Build and push an image to container registry
      inputs:
        command: buildAndPush
        repository: $(imageRepository)
        dockerfile: $(dockerfilePath)
        containerRegistry: $(dockerRegistryServiceConnection)
        tags: |
          $(tag)

在自动构建过程中,它会COPY ./server/requirements.txt .在标题中抛出错误。

阅读这个问题,我尝试了一些建议的解决方案但没有解决方案,例如:

COPY ./server/requirements.txt /app
COPY server/requirements.txt /app
Run Code Online (Sandbox Code Playgroud)

另外,我也刚刚尝试过:

COPY requirements.txt /app
Run Code Online (Sandbox Code Playgroud)

仍然收到错误。

所以,有点难住了:

  1. 如何解决这个问题,以便它在 Pipelines 中正确构建并推送到 CRS...
  2. 如果是上下文问题,为什么在使用 Skaffold 时本地开发中没有问题

实际上,示例项目具有类似的项目结构:

pipelines-javascript-docker/
  app/
    Dockerfile

它运行良好......有些我可能明显忽略了一些东西。

在更仔细地查看示例项目(该项目与我想要做的结构相同)之后,我最终复制了其Dockerfile格式。我最终得到了这个,效果很好:

FROM python:3.7-slim
ENV PYTHONUNBUFFERED 1
WORKDIR /app
EXPOSE 5000
COPY requirements*.txt ./
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "manage.py", "collectstatic"]
CMD ["gunicorn", "-b", ":5000", "--log-level", "info", "config.wsgi:application"]
