Node.js 如何在Github操作中设置Dockerfile参数

我有一个Node.js服务的Dockerfile，我试图通过使用Github操作将其推送到我的Digitalocean注册表

My Node.js服务需要一个由我自己在npm.js注册表上托管的私有包

在我的Dockerfile中，我有一个参数：

FROM node:14-slim

ARG NODE_ENV=production

EXPOSE 5000

WORKDIR /usr/src/app

ARG NPM_TOKEN

COPY .npmrc .npmrc

COPY package*.json ./

RUN npm install

RUN rm -f .npmrc

COPY src src

CMD ["npm", "start"]

以及以下.npmrc文件：

//registry.npmjs.org/:_authToken=${NPM_TOKEN}

在我的Github操作工作流中，我有两个操作。一个用于运行测试：

name: tests-user-service

on:
  pull_request:
    paths:
      - 'user-service/**'

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2

      - name: Install dependencies & run tests
        run: cd user-service && npm install && npm run test:ci
        env:
          NPM_TOKEN: ${{secrets.NPM_ACCESS_TOKEN}}

一个用于构建docker文件并将其推送到注册表：

name: deploy-user-service

on:
  push:
    branches:
      - main
    paths:
      - 'user-service/**'

jobs:
  build:
    runs-on: ubuntu-latest
    steps:

      - name: Check Out Repo
        uses: actions/checkout@v2

      - name: Install DigitalOcean Controller
        uses: digitalocean/action-doctl@v2
        with:
          token: ${{ secrets.DIGITALOCEAN_ACCESS_TOKEN }}

      - name: Set up Docker Builder
        uses: docker/setup-buildx-action@v1

      - name: Authenticate with DigitalOcean Container Registry
        run: doctl registry login --expiry-seconds 600

      - name: Build and Push to DigitalOcean Container Registry
        uses: docker/build-push-action@v2
        with:
          context: ./user-service
          push: true
          tags: registry.digitalocean.com/xxx/xxx:latest
        env:
          NPM_TOKEN: ${{secrets.NPM_ACCESS_TOKEN}}

      - name: Logout from DigitalOcean Container Registry
        run: doctl registry logout

现在，测试文件工作了。因此我知道NPM_访问_令牌设置正确

部署文件失败。它告诉我：

#10 [5/7] RUN npm install
#10 sha256:28b0590a43c14b889983d16b5e375f0156f7fdacc29e32fc3c219bce54e61d69
#10 0.317 Error: Failed to replace env in config: ${NPM_TOKEN}

#10 2.784 npm ERR! code E404
#10 2.790 npm ERR! 404 Not Found - GET https://registry.npmjs.org/@xxx%2fxxx - Not found
#10 2.790 npm ERR! 404 
#10 2.790 npm ERR! 404  '@xxx/xxx@^0.0.11' is not in the npm registry.
#10 2.790 npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

我在Dockerfile中尝试了以下操作：

FROM node:14-slim

ARG NODE_ENV=production

EXPOSE 5000

WORKDIR /usr/src/app

ARG NPM_TOKEN

ENV NPM_TOKEN ${NPM_TOKEN}

COPY .npmrc .npmrc

COPY package*.json ./

RUN npm install

RUN rm -f .npmrc

COPY src src

CMD ["npm", "start"]

然后它出错了，告诉我：

#10 [5/7] RUN npm install
#10 sha256:28b0590a43c14b889983d16b5e375f0156f7fdacc29e32fc3c219bce54e61d69
#10 0.317 Error: Failed to replace env in config: ${NPM_TOKEN}

#10 2.784 npm ERR! code E404
#10 2.790 npm ERR! 404 Not Found - GET https://registry.npmjs.org/@xxx%2fxxx - Not found
#10 2.790 npm ERR! 404 
#10 2.790 npm ERR! 404  '@xxx/xxx@^0.0.11' is not in the npm registry.
#10 2.790 npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

那么它就找不到模块了。我假设发生这种情况是因为NPM_令牌现在设置为空字符串，就像在tests操作中一样，它工作正常

你知道我还能尝试什么吗？

事实上，我已经想好了。必须将

build args

添加到build和Push部分，并从中删除

env

因此，不是：

- name: Build and Push to DigitalOcean Container Registry
  uses: docker/build-push-action@v2
  with:
    context: ./user-service
    push: true
    tags: registry.digitalocean.com/xxx/xxx:latest
  env:
    NPM_TOKEN: ${{secrets.NPM_ACCESS_TOKEN}}

应使用此选项：

- name: Build and Push to DigitalOcean Container Registry
  uses: docker/build-push-action@v2
  with:
    context: ./user-service
    push: true
    tags: registry.digitalocean.com/xxx/xxx:latest
    build-args: NPM_TOKEN=${{secrets.NPM_ACCESS_TOKEN}}
