I'm don't sure the ISPConfig have a docker to install or not? or I should setup ispconfig by my self I ask because may save time for install and very confuse how to config Thank
Using Docker makes not much sense to install a hosting control panel, that's why there is no official docker image for it. Some ISPConfig users have created docker files though, you can probably find them using a search engine of your choice. ISPConfig installation instructions can be found at ispconfig.org website.
