## Chrome Headless fails due to sandbox issues
|
|
|
|
- make sure kernel version is up-to-date
|
|
- read about linux sandbox here: https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md
|
|
- try running without the sandbox (**Note: running without the sandbox is not recommended due to security reasons!**)
|
|
```js
|
|
const browser = await puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});
|
|
```

## Running Puppeteer in Docker
|
|
|
|
Using headless Chrome Linux to run Puppeteer in Docker container can be tricky.
|
|
The bundled version Chromium that Puppeteer installs is missing the necessary
|
|
shared library dependencies.
|
|
|
|
To fix this, you'll need to install the latest version of Chrome dev in your
|
|
Dockerfile:
|
|
|
|
```
|
|
FROM node:8-slim
|
|
|
|
# Install latest chrome dev package.
|
|
# Note: this installs the necessary libs to make the bundled version of Chromium that Pupppeteer
|
|
# 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 \
|
|
--no-install-recommends \
|
|
&& rm -rf /var/lib/apt/lists/* \
|
|
&& apt-get purge --auto-remove -y curl \
|
|
&& rm -rf /src/*.deb
|
|
|
|
# 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
|
|
|
|
# Install puppeteer so it's available in the container.
|
|
RUN yarn add puppeteer
|
|
|
|
# Add pptr user.
|
|
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 user as non privileged.
|
|
USER pptruser
|
|
|
|
CMD ["google-chrome-unstable"]
|
|
```
|
|
|
|
Build the container:
|
|
|
|
```bash
|
|
docker build -t puppeteer-chrome-linux .
|
|
```
|
|
|
|
Run the container by passing `node -e "<yourscript.js content as a string>` as the command:
|
|
|
|
```bash
|
|
docker run -i --rm --name puppeteer-chrome puppeteer-chrome-linux node -e "`cat yourscript.js`"
|
|
```
|
|
|
|
There's a full example at https://github.com/ebidel/try-puppeteer that shows
|
|
how to run this setup from a webserver running on App Engine Flex (Node).

|
## Running Puppeteer on Heroku
|
|
|
|
Running Puppeteer on Heroku requires some additional dependencies that aren't included on the Linux box that Heroku spins up for you. To add the dependencies on deploy, add the Puppeteer Heroku buildpack to the list of buildpacks for your app under Settings > Buildpacks.
|
|
|
|
The url for the buildpack is https://github.com/jontewks/puppeteer-heroku-buildpack
|
|
|
|
When you click add buildpack, simply paste that url into the input, and click save. On the next deploy, your app will also install the dependencies that Puppeteer needs to run.
