可以在Google云端功能中运行无头Chrome / Chromium？ [英] Possible to run Headless Chrome/Chromium in a Google Cloud Function?

问题描述

有没有办法运行无头Chrome / Chromium 在谷歌云功能？我知道我可以在GCF中包含并运行静态编译的二进制文件。我可以得到一个静态编译版本的Chrome吗？

解决方案

我刚刚部署了一个运行无头的GCF函数铬。一对夫妇：

1. 您必须在Debian 8上静态编译Chromium和NSS


2. 在启动Chromium之前将环境变量修补为指向NSS


3. 的性能比您在AWS Lambda上获得的性能差得多（3+秒）

对于1，您应该能够在网上找到大量说明。





对于2， m使用如下：



  static executablePath（）{
 let bin = path.join（__ dirname，'。 '，'bin'，'chromium'）; 
 let nss = path.join（__ dirname，'..'，'bin'，'nss'，'Linux3.16_x86_64_cc_glibc_PTH_64_OPT.OBJ'）; 
 
 if（process.env.PATH === undefined）{
 process.env.PATH = path.join（nss，'bin'）; 
} else if（process.env.PATH.indexOf（nss）=== -1）{
 process.env.PATH = [path.join（nss，'bin'），process.env 。路径]。加入（ '：'）; 
} 
 
 if（process.env.LD_LIBRARY_PATH === undefined）{
 process.env.LD_LIBRARY_PATH = path.join（nss，'lib'）; 
} else if（process.env.LD_LIBRARY_PATH.indexOf（nss）=== -1）{
 process.env.LD_LIBRARY_PATH = [path.join（nss，'lib'），process.env .LD_LIBRARY_PATH]。加入（ '：'）; 
} 
 
 if（fs.existsSync（'/ tmp / chromium'）=== true）{
 return'/ tmp / chromium'; 
 
 
返回新的Promise（
（resolve，reject）=> {
 try {
 fs.chmod（bin，'0755'， （）=> {
 fs.symlinkSync（bin，'/ tmp / chromium'）; return resolve（'/ tmp / chromium'）; 
}）; 
} catch（error ）{
 return reject（error）; 
} 
} 
）; 
} 
  

启动Chrome时还需要使用一些必需的参数，即：

   -  disable-dev-shm-usage 
 --disable-setuid-sandbox 
 --no -first-run 
 --no-sandbox 
 --no-zygote 
 --single-process 
  

我希望这有助于。




Is there any way to run Headless Chrome/Chromium in a Google Cloud Function? I understand I can include and run statically compiled binaries in GCF. Can I get a statically compiled version of Chrome that would work for this?

解决方案

I've just deployed a GCF function running headless Chrome. A couple takeways:

1. you have to statically compile Chromium and NSS on Debian 8
2. you have to patch environment variables to point to NSS before launching Chromium
3. performance is much worse than what you'd get on AWS Lambda (3+ seconds)

For 1, you should be able to find plenty of instructions online.

For 2, the code that I'm using is the following:

static executablePath() {
  let bin = path.join(__dirname, '..', 'bin', 'chromium');
  let nss = path.join(__dirname, '..', 'bin', 'nss', 'Linux3.16_x86_64_cc_glibc_PTH_64_OPT.OBJ');

  if (process.env.PATH === undefined) {
    process.env.PATH = path.join(nss, 'bin');
  } else if (process.env.PATH.indexOf(nss) === -1) {
    process.env.PATH = [path.join(nss, 'bin'), process.env.PATH].join(':');
  }

  if (process.env.LD_LIBRARY_PATH === undefined) {
    process.env.LD_LIBRARY_PATH = path.join(nss, 'lib');
  } else if (process.env.LD_LIBRARY_PATH.indexOf(nss) === -1) {
    process.env.LD_LIBRARY_PATH = [path.join(nss, 'lib'), process.env.LD_LIBRARY_PATH].join(':');
  }

  if (fs.existsSync('/tmp/chromium') === true) {
    return '/tmp/chromium';
  }

  return new Promise(
    (resolve, reject) => {
      try {
        fs.chmod(bin, '0755', () => {
          fs.symlinkSync(bin, '/tmp/chromium'); return resolve('/tmp/chromium');
        });
      } catch (error) {
        return reject(error);
      }
    }
  );
}

You also need to use a few required arguments when starting Chrome, namely:

--disable-dev-shm-usage
--disable-setuid-sandbox
--no-first-run
--no-sandbox
--no-zygote
--single-process

I hope this helps.
