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
It sounds like your outgrowing docker. Maybe switch to Kubernetes at some point?
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
