i create a ipa on centos 8 (domain name = my_company_2)
how to create trust between to domain.
i want to use samba for windows connectoin and ipa for all linux/unix


This is not related to LInux containers as far as you mention betwen ipa and samba access.

By the way, why dontn’t you look for nexcloud/owncloud?
