How should i deploy new versions of molecular services?
The documentation explains well how to start them with moleculer-runner, but i can't find what is the proper way reload them without downtime.
The zero-downtime updating is not part of the framework, it's a system admin/devops issue. I recommend using Kubernetes for deploying upgraded containers with zero-downtime: https://kubernetes.io/docs/tutorials/kubernetes-basics/update/update-intro/
