InFlightConn

为主动防止服务因负载过高而不堪重负，可以通过 inFlightConn TCP 中间件限制每个 IP 允许的同时连接数。

配置示例¶

结构化 (YAML)

# Limiting to 10 simultaneous connections
tcp:
  middlewares:
    test-inflightconn:
      inFlightConn:
        amount: 10

结构化 (TOML)

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

容器标签

labels:
  - "traefik.tcp.middlewares.test-inflightconn.inflightconn.amount=10"

服务标签

// Limiting to 10 simultaneous connections
{
  //..
  "Tags" : [
    "traefik.tcp.middlewares.test-inflightconn.inflightconn.amount=10"
  ]
}

Kubernetes

apiVersion: traefik.io/v1alpha1
kind: MiddlewareTCP
metadata:
  name: test-inflightconn
spec:
  inFlightConn:
    amount: 10

字段	说明	默认值	必填
`amount`	`amount` 选项定义允许的最大同时连接数。如果已经打开了 `amount` 个连接，中间件将关闭新连接。	0	是
