Although Rselenium allows a screenshot of the current browser window
library(RSelenium) remDr <- remoteDriver( remoteServerAddr = "localhost", port = 4444, browserName = "Chrome" ) remDr$open() remDr$navigate("http://google.com") remDr$screenshot(display = T) # remDr$screenshot(file="screen.jpg")
So we need also a VNC server in the docker container as found at github.
After starting in the terminal
docker run -d -p 4444:4444 -p 5900:5900 -v /dev/shm:/dev/shm selenium/standalone-chrome:4.0.0-beta-1-prerelease-20210207
we can watch live at vnc://127.0.0.1:5900 what’s going on.
