Selenium in win docker container fails with "http request 60 second timeout" issue
thede...@gmail.com
Selenim test works fine locally on win10 or in a clean Windows Server 2016 with UI.
If I build a dockers container for windows and copy my tests in it fails with this message. Consistent on ff and chrome drivers. Seems to be a common error with not a lot of fixes out there.
Github repo with goodies - https://github.com/jhealy/devfish-shares/tree/master/docker-selenium-aspnet45
Repro
- docker build -f dockerfile -t aspnet45 .
- docker run -d --name aspnet45run -p 5000:80 aspnet45
Verify we are serving web pages
- Invoke-WebRequest http:\\localhost:5000 -UseBasicParsing
Connect to container with interactive ps
- docker exec -it aspnet45run powershell
Inside the container – make sure we can hit website
- Invoke-WebRequest http://localhost -UseBasicParsing
Extract out firefox, which we copy in with the docker file
- Cd \seleniumtests\assets
- .\firefox_setup_66.0.3.exe -ms
Run selenium console app, which works fine outside container
- Cd \
- Cd seleniumtests
- .\SeleniumDockerTests.exe http://localhost
Then I cry miserably cause I get the network timeout. Error dump below. Same thing for Chrome and FF with variance on the namespaces.
