我有一个NX工作区，只包含一个angular应用程序和它的e2e应用程序，这是使用cypress
我正在尝试为端到端测试创建一个docker映像，但是当我运行docker容器时失败了。这是我的Dockerfile，它现在位于工作空间的根文件夹中。
FROM node:lts-alpine
WORKDIR /app
# add `/app/node_modules/.bin` to $PATH
ENV PATH /app/node_modules/.bin:$PATH
# install and cache app dependencies
COPY package.json /app/package.json
COPY decorate-angular-cli.js /app/decorate-angular-cli.js
RUN npm install
RUN npm install -g @angular/cli@latest
RUN npm install reflect-metadata tslib
# add cypress dependencies for image build
RUN apk add xauth xvfb
# add app
COPY . /app
CMD npm run e2e -- --headless
映像已构建，但当我运行容器时，我得到柏树依赖错误。

It looks like this is your first time using Cypress: 7.7.0

我需要知道这是否是用Nxdockerizing e2e apps的正确方法，如果是的话，那么我在这里错过了什么。
谢谢!
问题是Alpine Linux还不支持Cypress(或者可能永远不支持)。我建议您使用官方支持的Cypress Docker映像之一。即使你设法让Cypress在Alpine上运行，它也需要下载大量的外部依赖来构建Chrome/Electron，这将使磁盘大小优化可以忽略不计。
