A tiny zincati helper that provides a fleetlock backend for consul, and also serves as a HTTP metrics proxy.
This is a babashka script with no external dependencies, so it can just be run from source with bb.
Configuration is through environment variables:
| GROUP_DOWN_MAP | json map: group name -> max hosts down (by default, at most 1 host down per group) |
| BIND_IP | ip to bind to (default: 127.0.0.1) |
| BIND_PORT | port to bind to (default: 15535) |
| METRICS_IP | ip to bind the metrics proxy to (default: unset and disabled) |
| METRICS_PORT | port to bind the metrics proxy to (default: 9090) |
When running in a container you should set an init process to handle signals, and you need to mount /run/zincati/public/ and convince SELinux to allow access to promsock.
