Teacher connected to the Classroom-Network opens the webbrowser and log-in to the server. School could have a small Web-Server installed on the Classroom-Router or switch.

Change basic setting like WLAN-Password, SSID, etc. ISP could have a small Web-Server installed on Client devices. Installing Dockers on my Router could be a very nice solution. My handfull of devices usually make each 1 SQL-Request a day. I for exemple need at home very small MariaDB-Server for a software I use (Devolutions RDM).

Like ioT-Server, Web-Server, Data and Logging, Authentication (freeradius), DNS (pihole) etc. I know a lot of IT-Enthusiast wo use RPi's at home as some sort of low performance Server. There is always a small Feature or Service from the All-in-One Router that Mikrotik can't provide. I find it difficult sometimes to implement a Mikrotik-Routers in a SOHO or SME's environment. So the Docker-Feature is a welcome Tool for my Toolbox I use Mikrotik-Devices all the time to solve problem no other Router can ! In other words, no Entreprise with On-Site virtualization capability, will move there DNS-Server to a Mikrotik-Device! I don't think the Docker-Feature will be widely used in the 'Entreprise' enviroment.
