This is related to a maven 3.9.6-based and java 17-based selenium automation project used to log and download files from a remote site, it works fine as a nonotorized application.

This application uses the Chrome browser in headless mode. Currently, the Chrome drivers and relevant Maven versions are bundled with it in the application. The Chrome drivers have to match the Chrome browser for the Selenium operations to work without error. The Chrome browser version in the current server is 123.0.6312.86 and the drivers in drivers/chromedriver-linux64 are used. The Chrome drivers need to be updated if the Chrome browser is updated on the server. I have placed the report-automation.jar at the root level of the application during the build.

Currently, the Chrome browser should be installed on a server and is not bundled into the application in any way. The related Chrome drivers are only bundled in the application. how can this application be dockerized? should the Chrome browser and Chrome driver installation be handled in the docker file?

Given below is a sample docker file I created for this scenario. But the Chrome browser and Chrome driver-related sections need to be updated Could the docker file be optimized further to support containerization optimally?

Furthermore, the outcome of this application is to download a CSV report Downloaded-Report folder in the application. How can this operation be handled if the application is dockerized?

any suggestions on how this issue may be handled?

To run the Java Selenium application on a separate server I am attempting to build a Dockerfile install Chrome and use a headless way to run a browser. (This application provides a desired output when executed locally.) But when attempting to run the docker I receive this error.

Am I missing something in the docker build or the Java-based configurations provided.? How should chrome driver-related configurations be added?

Technologies used

• OS - Ubuntu 22.04 LTS
• Docker version - Docker version 24.0.2, build cb74dfc
• Java version - java version "17.0.4" 2022-07-19 LTS
• Selenium version - 4.11.0
• Chrome version - Google Chrome 120.0.6099.199--

Update: There also seems to be another way to run Chrome using selenium/standalone-chrome. Is it possible to integrate chrome/selenium with another docker using this method? which is the preferred option of these two methods?
