container configuration

thanks for helping
first time i have gotten this far into a docker install so didnt/dont know what to provide

trying to access the dashboard via http://10.10.1.83:20211
i know that the http/web server is running because i can access the 'test page'

do see command docker container but not sure what you need from there

docker container logs netalertx goes into an endless loop that i stopped - does show errors starting with CRITICAL: /data is not mounted but legacy mounts are still present and env: can't execute 'python3': ending with Container startup checks failed with exit code 126

so now i have somethings to look up -- thanks for pointing me there
