Hey @rehamkhalil3 , You can do it by just modifying the host file and add an entry mapping the custom DNS name to the IP address of the Docker container.127.0.0.1 mycustomdomain.com
Then again pull the image from hub and run it on your desired port and after running successfully you can access it by your custom DNS.

You can change the test server domain by changing the variable in the main Makefile the Domain config variable for generating the test certs (here https://github.com/chromium/badssl.com/blob/master/Makefile#L36). You'll then also need to change the /etc/hosts list to use the new domain (or however you are setting up DNS for your test server instance).

I have not tried re-configuring the test server in a long time though, so there may be some rough edges. If you do this and report back I'd be happy to brainstorm improvements to running and customizing the test server.
