If I needed 100% automatic updates I would
- split to a web + database containers
- put web containers behind a load balancer
- build a new web image, cycle it in once I am sure it is responding properly to 200s
This is very complicated to do in a safe way, hence it is not automatic .
Definately don’t be entering containers and changing config inside outside of our supported docker manager that works on a single host, single container setup.
