I am planning to implement the following features in the future.
Support Failover-Mode (secondary ip address) as in official DLS.
Note: There is no Load-Balancing / Round-Robin HA Mode supported! If you want to use that, consider to use Docker-Swarm with shared/cluster database (e.g. postgres).
See ha branch for current status.
Add a user interface to manage origins and leases.
See ui branch for current status.
Instead of using environment variables, configuration files and manually create certificates, store configs and certificates in database (like origins and leases). Also, there should be provided a startup assistant to prefill required attributes and create instance-certificates. This is more user-friendly and should improve fist setup.
