### Prerequisites

* Runs as non-root with fixed UID 10777 and GID 10777. See [howto prepare volume permissions](https://github.com/codeclou/doc/blob/master/docker/README.md).
 * See [howto use SystemD for named Docker-Containers and system startup](https://github.com/codeclou/doc/blob/master/docker/README.md).

### Usage

Assuming you are currently inside a NodeJS Project containing a `package.json`, you can do an `npm install` like this:

```
docker run \
    -i -t \
    -v $(pwd):/work \
    --shm-size=128M \
    codeclou/docker-nodejs-chrome-xvfb:node-8.1.3-chome-59 \
    npm install
```

Or take a screenshot via:

```
docker run \
    -i -t \
    -v $(pwd):/work \
    --shm-size=128M \
    codeclou/docker-nodejs-chrome-xvfb:node-8.1.3-chome-59 \
    google-chrome --no-sandbox --headless --disable-gpu --window-size=1280,768 \
                  --screenshot=/work/screenshot.png https://codeclou.io
```

### Usage with Karma.js

Since **Chrome 59** we must use several things, which is handled by docker entrypoint:

* We need to start pulseaudio, or Chrome will complain about [Audio Managers](https://stackoverflow.com/questions/43943721/error-running-headless-chromium-on-ubuntu)
 * We need to start dbus
 * We need to start xvfb
 * We need some flags for chrome startup
 * We need a symlink to chromium binary

When using with [karma.js](https://github.com/karma-runner/karma):

* Start docker with a greater `/dev/shm` cache and use `--shm-size=128M` or greater.
 * Configure karma config with Chrome flags:

```
...
  logLevel: config.LOG_DEBUG,
...
  browsers: ['Chrome_without_security'],
  singleRun: false,
  customLaunchers: {
    Chrome_without_security: {
      base: 'Chrome',
      flags: [
        //'--headless', // DO NOT USE headless !!!
        '--disable-gpu',
        '--no-sandbox',
      ]
    }
  }
});
```

-----

&nbsp;

### Usage with Protractor

In your `protractor.conf.js`

```js
// ...

exports.config = {
  // ...
  capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
      'args': ['--disable-gpu', '--no-sandbox']
    }
  },
// ...
};
```
