检查以下内容
Dockerfile，阅读注释。它应该正常运行。
# First, we need to make sure all dependencies are there. If you are using docker, then the important dependencies are already present on most node images. FROM node:8# To run Headful mode, you will need to have a display, which is not present in a server. # To avoid this, we will use Xvfb, and create a fake display, so the chrome will think there is a display and run properly. # So we just need to install Xvfb and Puppeteer related dependencies.RUN apt-get update && apt-get install -yq gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget x11vnc x11-xkb-utils xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic x11-apps xvfb# I am going to ignore dumb-init or such for now since it will add complexities to understand what is actually needed here.# Assuming we are working on /app folder, cd into /appWORKDIR /app# Copy package.json into app folderCOPY package.json /app# Install dependenciesRUN npm installCOPY . /app# Start server on port 3000EXPOSE 3000# I'll also assume you are going to use root user, # and your script has `--no-sandbox` and `--disable-setuid-sandbox` arguments.# We run a fake display and run our script.# Start script on XvfbCMD xvfb-run --server-args="-screen 0 1024x768x24" npm start
然后我用以下命令运行它，
# build the appsudo docker build -t app .# start the container, expose to network and remove after runningsudo docker run --network=host -it app
我上面使用的脚本的示例结果，可以是任何脚本，
