Node.js 應用程序無法在 Azure Web 應用程序與自定義容器上啟動

Question

我將 node.js 應用程序部署到應用程序服務。 最初我采用了node14提供的運行時應用服務。 但是，puppeteer 在 node14 運行時不起作用，我創建了自定義容器來使用 puppeteer/Headless Chrome。

我可以成功部署，但服務器沒有打開。 誰能讓我知道我錯過了什么？

FROM node:14
# 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.

# 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

# Headfull mode
# Install dependencies
# 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.

您需要添加CMD和ENTRYPOINT以在 Dockerfile 中啟動您的應用程序。 你錯過了。 因此，當您從 Dockerfile 創建映像並將其部署到 Web 應用程序時，沒有應用程序按預期運行。
