Traefik InFlightConn Middleware - TCP	Limiting the number of simultaneous connections.

To proactively prevent Services from being overwhelmed with high load, the number of allowed simultaneous connections by IP can be limited with the inFlightConn TCP middleware.

Configuration Examples

tcp:
  middlewares:
    test-inflightconn:
      inFlightConn:
        amount: 10

# Limiting to 10 simultaneous connections
[tcp.middlewares]
  [tcp.middlewares.test-inflightconn.inFlightConn]
    amount = 10
