This is a tool to build a freebsd service cluster
- Basic Idea
-
Use consul as service discovery
-
Use nomad to schedule services
-
Use traefik as service redirect
-
Use CARP to handle service fail over
-
Use FreeBSD jail management tool(pot) to manage service jail
-
Use vxlan to connect jails inside cluster
- Usage
