# EntryPoints
|
|
|
|
Opening Connections for Incoming Requests
|
|
{: .subtitle }
|
|
|
|
|
|
|
|
EntryPoints are the network entry points into Traefik.
|
|
They define the port which will receive the packets,
|
|
and whether to listen for TCP or UDP.
|
|
|
|
## Configuration Examples
|
|
|
|
??? example "Port 80 only"
|
|
|
|
```toml tab="File (TOML)"
|
|
## Static configuration
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
## Static configuration
|
|
entryPoints:
|
|
web:
|
|
address: ":80"
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
## Static configuration
|
|
--entryPoints.web.address=:80
|
|
```
|
|
|
|
We define an `entrypoint` called `web` that will listen on port `80`.
|
|
|
|
??? example "Port 80 & 443"
|
|
|
|
```toml tab="File (TOML)"
|
|
## Static configuration
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.websecure]
|
|
address = ":443"
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
## Static configuration
|
|
entryPoints:
|
|
web:
|
|
address: ":80"
|
|
|
|
websecure:
|
|
address: ":443"
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
## Static configuration
|
|
--entryPoints.web.address=:80
|
|
--entryPoints.websecure.address=:443
|
|
```
|
|
|
|
- Two entrypoints are defined: one called `web`, and the other called `websecure`.
|
|
- `web` listens on port `80`, and `websecure` on port `443`.
|
|
|
|
??? example "UDP on port 1704"
|
|
|
|
```toml tab="File (TOML)"
|
|
## Static configuration
|
|

|
|
[entryPoints.streaming]
|
|
address = ":1704/udp"
|
|
```
|
|
|
|

## Static configuration
|
|

|
|
```
|
|
|
|
```bash tab="CLI"

|
## Configuration
|
|
|
|
### General
|
|
|
|
EntryPoints are part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
|
|
You can define them using a toml file, CLI arguments, or a key-value store.

|
|
|
|
### Address
|
|
|
|
The address defines the port, and optionally the hostname, on which to listen for incoming connections and packets.
|
|
It also defines the protocol to use (TCP or UDP).
|
|
If no protocol is specified, the default is TCP.
|
|
The format is:
|
|
|
|
```bash
|
|
[host]:port[/tcp|/udp]
|
|
```
|
|
|
|
If both TCP and UDP are wanted for the same port, two entryPoints definitions are needed, such as in the example below.
|
|
|
|
??? example "Both TCP and UDP on port 3179"
|
|
|
|
```toml tab="File (TOML)"
|
|
## Static configuration
|
|
[entryPoints]
|
|
[entryPoints.tcpep]
|
|
address = ":3179"
|
|
[entryPoints.udpep]
|
|
address = ":3179/udp"
|
|
```
|
|
|
|
```yaml tab="File (YAML)"
|
|
## Static configuration
|
|
entryPoints:
|
|
tcpep:
|
|
address: ":3179"
|
|
udpep:
|
|
address: ":3179/udp"
|
|
```
|
|
|
|
```bash tab="CLI"
|
|
## Static configuration
|
|
--entryPoints.tcpep.address=:3179
|
|
--entryPoints.udpep.address=:3179/udp
|
|
```
|
|
|
|
### Forwarded Headers
|
|
|
|
You can configure Traefik to trust the forwarded headers information (`X-Forwarded-*`).
|
|
|
|
??? info "`forwardedHeaders.trustedIPs`"
|
|
|
|

|
|
|
|

```
|
|

|
|
### Transport
|
|
|
|
#### `respondingTimeouts`
|
|
|
|
`respondingTimeouts` are timeouts for incoming requests to the Traefik instance.
|
|
Setting them has no effect for UDP entryPoints.
|
|
|
|
??? info "`transport.respondingTimeouts.readTimeout`"
|
|
|
|
_Optional, Default=0s_
|
|
|
|
`readTimeout` is the maximum duration for reading the entire request, including the body.
|
|
|
|
If zero, no timeout exists.
|
|
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
|
|
If no units are provided, the value is parsed assuming seconds.
|
|
|
|
```toml tab="File (TOML)"

```
|
|
|
|
??? info "`transport.respondingTimeouts.writeTimeout`"
|
|
|
|
_Optional, Default=0s_
|
|
|
|
`writeTimeout` is the maximum duration before timing out writes of the response.
|
|
|
|
It covers the time from the end of the request header read to the end of the response write.
|
|
If zero, no timeout exists.
|
|
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
|
|
If no units are provided, the value is parsed assuming seconds.

??? info "`transport.respondingTimeouts.idleTimeout`"
|
|

|
_Optional, Default=180s_
|
|
|
|
`idleTimeout` is the maximum duration an idle (keep-alive) connection will remain idle before closing itself.
|
|
|
|
If zero, no timeout exists.
|
|
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
|
|
If no units are provided, the value is parsed assuming seconds.

|

|
|
#### `lifeCycle`
|
|
|
|
Controls the behavior of Traefik during the shutdown phase.
|
|
|
|
??? info "`lifeCycle.requestAcceptGraceTimeout`"
|
|
|
|
_Optional, Default=0s_
|
|
|
|
Duration to keep accepting requests prior to initiating the graceful termination period (as defined by the `graceTimeOut` option).
|
|
This option is meant to give downstream load-balancers sufficient time to take Traefik out of rotation.
|
|
|
|
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).
|
|
|
|
If no units are provided, the value is parsed assuming seconds.
|
|
The zero duration disables the request accepting grace period, i.e., Traefik will immediately proceed to the grace period.

|
|
|
|
Can be provided in a format supported by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration) or as raw values (digits).

|
### ProxyProtocol
|
|
|
|
Traefik supports [ProxyProtocol](https://www.haproxy.org/download/2.0/doc/proxy-protocol.txt) version 1 and 2.
|
|
|
|
If Proxy Protocol header parsing is enabled for the entry point, this entry point can accept connections with or without Proxy Protocol headers.
|
|
|
|
If the Proxy Protocol header is passed, then the version is determined automatically.
|
|
|
|
??? info "`proxyProtocol.trustedIPs`"
|
|
|
|

!!! warning "Queuing Traefik behind Another Load Balancer"
|

When queuing Traefik behind another load-balancer, make sure to configure Proxy Protocol on both sides.
|
|
Not doing so could introduce a security risk in your system (enabling request forgery).
|
