lazyatom / dokku-chrome Goto Github PK

Hello! I'm using Watir with dokku chrome and so far it's amazing. But I have an issue of how to store the download files or change the default. I enable a storage folder on the app that is linked to store the files. Any help will be appreciated.

An example of how I'm running the test:

chrome_url = ENV['CHROME_URL']
@download_directory = Rails.env.production? ? "#{Rails.root.to_s}/storage" : "#{Rails.root.to_s}/tmp"
prefs = {
   'download' => {
      'default_directory' => @download_directory,
      'prompt_for_download' => false,
      'directory_upgrade' => true,
   },
}

args = [ '--headless', '--no-sandbox']

@browser = Watir::Browser.new(:chrome, options: {prefs: prefs, args: args}, url: "#{chrome_url}/webdriver")
@browser.goto "https://www.dwsamplefiles.com/?dl_id=176"

Probably a long-shot question... the Readme isn't clear on how dokku-chrome is not supposed to be used. So I'd like to clarify.

I have a Rails web app running inside dokku, the web app has webdrivers and watir (which basically is built on top of Selenium) in Gemfile. When the web app runs, it tries to open a headless Chrome browser to read a web page. But even after installing dokku-chrome, the app would throw this error: "Failed to find Chrome binary". So is dokku-chrome supposed to provide a Chrome binary inside dokku? If not, any idea how a Chrome binary could be installed in dokku?

Appreciate any pointer.

I am trying to access chrome executable to work. Is there any way I can get BROWSER_PATH for the chrome installed ?
