Crowdsec-Manager in multi-server setup

[fromCologne]

I use two docker hosts with LAPI on one of it and only Log Processor on the second docker host. Separated in two network segments and different subnets.
In the log I see:
{"level":"info","time":"xxxx","msg":"Multi-host Docker client initialized with single default host"}
I see environment variable DOCKER_HOSTS. This is necessary for my design?

I use docker-compose.yml
environment:

• ENVIRONMENT=production
  But in the log I have:
  [crowdsec-manager] .... [GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
