Maximum number of docker networks (lemm.ee)

Hey guys, I was happily running 44 docker containers for a while on Debian host. Today I tried to add a new service (uptime-kuma) using portainer stacks, but I got this error:

Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

Quick google led me to this link where I found possible problem with max number of docker networks. I did docker network prune, it removed 5 networks that were not in use and viola, uptime-kuma is working now!

Am I reaching the limit? What to do if I need 10 more services on the same host? I bet I saw some people in this community running many more services

Oh rly? Im still reading about what others said and feels like I can still continue with docker. Ive heard about kubernetes many times. Even tho some people use them on single node, isnt that made for multiple nodes setup? I have to learn more about kubernetes

Take a look at K3S if you plan to use kubernetes on a single node.
