Running in Docker

[rcepka]

Hello, I created an R script which uses Selenider to collect some information from the web. I want to run this script from a Docker container, but I am getting this error on the Docker start:

selenider installed
`google-chrome` and `chromium-browser` were not found. Try setting the `CHROMOTE_CHROME` environment variable to the executable of a Chromium-based browser, such as Google Chrome, Chromium or Brave or adding one of these executables to your PATH.
Error in initialize(...) : Invalid path to Chrome
Calls: selenider_session ... <Anonymous> -> initialize -> <Anonymous> -> initialize
Execution halted

Apparently, I am missing either Chromote or Selenium in my system. I prefer using Chromote over Selenium and attached as a Docker container, not installing it onto my server. Could you provide me some hints how to make it working, setup like this please?

Thank you very much.

From my memory, that error occurs when chromote::find_chrome() fails. This suggests that you have installed chromote successfully, but you don't actually have Google Chrome or Chromium installed (or if you do, chromote can't find it). I think that installing Chrome in your Docker image should fix this issue (I'm not super experienced with Docker, so I'm not sure exactly how you would do this).

If your docker file is like your one in rstudio/chromote#157, try installing chrome in the image in one of the 2 following ways:

RUN apt-get install -y wget
RUN wget -q https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
RUN apt-get install -y ./google-chrome-stable_current_amd64.deb

from this thread

RUN curl -LO https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
RUN apt-get install -y ./google-chrome-stable_current_amd64.deb

or from here

Hopefully, chromote would be able to find chrome and the container will start up without an error :)

@Doozy134 , Thank you for your hints, it works like a charm. I needed to add to my Dockerfile a line for OS updating otherwise I would be receiving errors about unmet dependencies; but this might be just my case determined by my particular base image. Thanks once again.

@ashbythorpe , many thanks to you too, you always respond with the best intention to help, also I understand that this type of request goes beyond the module support.

Closing as fixed.
