haliphax, 
Seen some grey-beards dogging on using containers to deliver applications lately, and I'm of two minds about it.
I understand the kernel of the argument, and I don't disagree with it.
On the other hand, I am currently working on a community server composed of many services:
- SSH server
- API server
- nginx server
- postgres server
- redis server
- proxy/load balancer
Does this need containers? No. Would it be less confusing/error prone without using them? Also no. Fuck no.
