Ini adalah skrip yang diberikan Eric Bidelman kepada saya (atau membantu saya membuat & mdash; saya cukup ingat).

Saya membutuhkan cara mudah untuk menghosting aplikasi web khusus yang dapat terhubung ke instance Chrome Tanpa Kepala di atas API Puppeteer. Artikel ini sebagian besar referensi untuk masa depan.

Kontainer docker relatif lurus ke depan:

Gunakan node: 8-slim 2. Instal semua dependensi yang diperlukan, termasuk Chrome. 3. Inisialisasi lingkungan 4. Salin aplikasi saya dari direktori saat ini (file dan aplikasi docker berada di folder yang sama) 5. Siapkan pengguna dan izin 6. Buka port dan jalankan aplikasi.

FROM node:8-slim
LABEL name "puppeteraas"

# See https://crbug.com/795759
RUN apt-get update && apt-get install -yq libgconf-2-4

# Install latest chrome dev package and fonts to support major 
# charsets (Chinese, Japanese, Arabic, Hebrew, Thai and a few others)
# Note: this installs the necessary libs to make the bundled version 
# of Chromium that Puppeteer
# installs, work.
RUN apt-get update && apt-get install -y wget --no-install-recommends \
    && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
    && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list' \
    && apt-get update \
    && apt-get install -y google-chrome-unstable fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst ttf-freefont \
      --no-install-recommends \
    && rm -rf /var/lib/apt/lists/* \
    && apt-get purge --auto-remove -y curl \
    && rm -rf /src/*.deb

# It's a good idea to use dumb-init to help prevent zombie chrome processes.
ADD https://github.com/Yelp/dumb-init/releases/download/v1.2.0/dumb-init_1.2.0_amd64 /usr/local/bin/dumb-init
RUN chmod +x /usr/local/bin/dumb-init

# Uncomment to skip the chromium download when installing puppeteer. 
# If you do, you'll need to launch puppeteer with:
#     browser.launch({executablePath: 'google-chrome-unstable'})
# ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD true

# Copy the app
COPY . /app/
#COPY local.conf /etc/fonts/local.conf
WORKDIR app
RUN npm i

# Add user so we don't need --no-sandbox.
RUN groupadd -r pptruser && useradd -r -g pptruser -G audio,video pptruser \
    && mkdir -p /home/pptruser/Downloads \
    && chown -R pptruser:pptruser /home/pptruser \
    && chown -R pptruser:pptruser ./node_modules

# Run everything after as non-privileged user.
USER pptruser

EXPOSE 8084
ENTRYPOINT ["dumb-init", "--"]
CMD ["npm", "run", "start"]

Untuk membuatnya tetap sederhana, saya telah mengabstraksi sebagian besar logika ke dalam skrip penampung galangan baru yang disebut kinlan: puppets yang memungkinkan Anda menyesuaikan cara Anda menerapkan aplikasi.

FROM kinlan/puppets:latest

# Copy the app
COPY . /app/
#COPY local.conf /etc/fonts/local.conf
WORKDIR app
RUN npm i

# Add user so we don't need --no-sandbox.
RUN groupadd -r pptruser && useradd -r -g pptruser -G audio,video pptruser \
    && mkdir -p /home/pptruser/Downloads \
    && chown -R pptruser:pptruser /home/pptruser \
    && chown -R pptruser:pptruser ./node_modules

# Run everything after as non-privileged user.
USER pptruser

EXPOSE 8084
ENTRYPOINT ["dumb-init", "--"]
CMD ["npm", "run", "start"]
