从 azure 中的 Dockerfile 向私人 npm 注册表进行身份验证？

问题描述

I have the below Dockerfile:我有以下 Dockerfile：

FROM node:alpine

WORKDIR ./usr/local/lib/node_modules/npm/

COPY .npmrc ./

COPY package.json ./
COPY package-lock.json ./
RUN npm ci

COPY . .


EXPOSE 3000

CMD ["npm", "run", "start-prod"]

This file is used in an azure pipeline like so:此文件在 azure 管道中使用，如下所示：

variables:
  - name: NPMRC_LOCATION
    value: $(Agent.TempDirectory)
    
  - stage: BuildPublishDockerImage
    displayName: Build and publish Docker image
    dependsOn: Build
    jobs:
      - job: BuildPublishDockerImage
        steps:
          - checkout: self
          - task: DownloadSecureFile@1
            name: npmrc
            inputs:
              secureFile: .npmrc
          - task: npmAuthenticate@0
            inputs:
              workingFile: $(NPMRC_LOCATION)/.npmrc
          - task: Docker@2
            displayName: Build a Docker image
            inputs:
              command: build
              arguments: --no-cache

I know .npmrc should be in that location (I run RUN ls in the Dockerfile and its there).我知道.npmrc应该在那个位置（我在 Dockerfile 和那里运行RUN ls ）。
However when I run it I keep getting this error:但是，当我运行它时，我不断收到此错误：

failed to solve with frontend dockerfile.v0: failed to build LLB: failed to compute cache key: "/.npmrc" not found: not found无法使用前端 dockerfile.v0 解决：构建 LLB 失败：计算缓存键失败：“/.npmrc”未找到：未找到

I just want to authenticate to a private npm registry.我只想对私有 npm 注册表进行身份验证。 I'm mystified by this.我对此感到困惑。 Grateful for any help.感谢您的帮助。
