Like, I have a generic Flask container repository that I clone as a starting base...change the domain name(s) on the config file, app name, etc. Then just copy things into the src/ directory and spin it up.
For me, this is really easy to spin up a new flask project. I do the same with golang [sort of, it really just downloads a binary+config file into a container that has all of my logging, etc setup].
The problem with doing LXC is where you have inheritance chains like this:
[Base Container of Ubuntu + Logging + Monitoring] -> [Base Flask Container] -> [Flask Container for Website X]
[Base Container of Ubuntu + Logging + Monitoring] -> [Base Flask Container] -> [Flask Container for API for Website X]
[Base Container of Ubuntu + Logging + Monitoring] -> [Container for Mail Service]
[Base Container of Ubuntu + Logging + Monitoring] -> [Container for Kibana]
[Base Container of Ubuntu + Logging + Monitoring] -> [Container for Redis-Cache]
etc.
Tbh, I think that is what docker really fixes. The ability to easily inherit containers so you only have to make changes in one spot to change all of them.
