Allow roles to be renamed without having to manually stop the old
containers.
If you have config like:
```
servers:
jobs:
hosts:
- vm3
```
And you want to rename `jobs` to `workers`, you can do:
```
servers:
workers:
previously:
- jobs
hosts:
- vm3
```
And the deployment will take care of stopping the old "jobs" containers.
Once deployed you can remove the `previously` key.
Kamal: Deploy web apps anywhere
From bare metal to cloud VMs, deploy web apps anywhere with zero downtime. Kamal has the dynamic reverse-proxy Traefik hold requests while a new app container is started and the old one is stopped. Works seamlessly across multiple hosts, using SSHKit to execute commands. Originally built for Rails apps, Kamal will work with any type of web app that can be containerized with Docker.
