Set up Selenium with a docker rails app on wsl2 - ruby-on-rails

Question

After following a couple of tutorials I can't figure out how to configure Selenium with:
a rails app on debian wsl2
the gem "Webdrivers"
docker
With my local application, Selenium worked properly with
require "webdrivers"
Since I have dockerized the app, everything works properly except Selenium.
When I run a js test I get
Webdrivers::NetworkError:
Net::HTTPServerException: 404 "Not Found" with https://github.com/mozilla/geckodriver/releases/download/v0/geckodriver-v0-linux64.tar.gz
It seems that the request url is not build correctly "v0"
When I hard code a version number in my config file like so
Webdrivers::Geckodriver.required_version = "0.32.0"
geckodriver is downloaded properly.
1- How can I configure webdriver to handle verssion automatically ?
Then I get this error message
Selenium::WebDriver::Error::SessionNotCreatedError:
Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line
What I understand is that it tries to reach for the firefox application. I have firefox installed on windows side and firefox-esr on wsl2/debian side.
2- How can I configure webdrivers and/or docker to run my tests with selenium ?
I have tried to hard code the firefox path.
Here is my webdrivers config, with many settings attempts.
Capybara.register_driver :remote_firefox do |app|
firefox_capabilities = ::Selenium::WebDriver::Remote::Capabilities.firefox
# (
# "moz:firefoxOptions": {
# "args": %w[headless window-size=1400,1400]
# },
# "binary": "/mnt/c/Users/Fz/AppData/Local/Microsoft/WindowsApps/firefox.exe"
# )
firefox_options = Selenium::WebDriver::Firefox::Options.new
firefox_options.binary = "/mnt/c/Users/Fz/AppData/Local/Microsoft/WindowsApps/firefox.exe"
Capybara::Selenium::Driver.new(
app,
browser: :remote,
url: "http://172.28.0.7:5555",
# desired_capabilities: firefox_capabilities,
options: firefox_options
)
end
RSpec.configure do |config|
config.before(:each) do
Capybara.current_driver = :remote_firefox
Capybara.javascript_driver = :remote_firefox
Capybara.app_host = "http://#{IPSocket.getaddress(Socket.gethostname)}:3000"
Capybara.server_host = IPSocket.getaddress(Socket.gethostname)
Capybara.server_port = 5555
end
end
