# EntryPoints
|
|
|
|
Opening Connections for Incoming Requests
|
|
{: .subtitle }
|
|
|
|
|
|
|
|
EntryPoints are the network entry points into Traefik.
|
|
They define the port which will receive the requests (whether HTTP or TCP).
|
|
|
|
## Configuration Examples
|
|
|
|
??? example "Port 80 only"
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
```
|
|
|
|
We define an `entrypoint` called `web` that will listen on port `80`.
|
|
|
|
??? example "Port 80 & 443"
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.web-secure]
|
|
address = ":443"
|
|
```
|
|
|
|
- Two entrypoints are defined: one called `web`, and the other called `web-secure`.
|
|
- `web` listens on port `80`, and `web-secure` on port `443`.
|
|
|
|
## 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.
|
|
|
|
See the complete reference for the list of available options:
|
|
|
|
```toml tab="File"
|
|
[entryPoints]
|
|
|
|
[entryPoints.EntryPoint0]
|
|
Address = ":8888"
|
|
[entryPoints.EntryPoint0.Transport]
|
|
[entryPoints.EntryPoint0.Transport.LifeCycle]
|
|
RequestAcceptGraceTimeout = 42
|
|
GraceTimeOut = 42
|
|
[entryPoints.EntryPoint0.Transport.RespondingTimeouts]
|
|
ReadTimeout = 42
|
|
WriteTimeout = 42
|
|
IdleTimeout = 42
|
|
[entryPoints.EntryPoint0.ProxyProtocol]
|
|
Insecure = true
|
|
TrustedIPs = ["foobar", "foobar"]
|
|
[entryPoints.EntryPoint0.ForwardedHeaders]
|
|
Insecure = true
|
|
TrustedIPs = ["foobar", "foobar"]
|
|
```
|
|
|
|
```ini tab="CLI"
|
|
--entryPoints.EntryPoint0.Address=:8888
|
|
--entryPoints.EntryPoint0.Transport.LifeCycle.RequestAcceptGraceTimeout=42
|
|
--entryPoints.EntryPoint0.Transport.LifeCycle.GraceTimeOut=42
|
|
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.ReadTimeout=42
|
|
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.WriteTimeout=42
|
|
--entryPoints.EntryPoint0.Transport.RespondingTimeouts.IdleTimeout=42
|
|
--entryPoints.EntryPoint0.ProxyProtocol.Insecure=true
|
|
--entryPoints.EntryPoint0.ProxyProtocol.TrustedIPs=foobar,foobar
|
|
--entryPoints.EntryPoint0.ForwardedHeaders.Insecure=true
|
|
--entryPoints.EntryPoint0.ForwardedHeaders.TrustedIPs=foobar,foobar
|
|
```
|
|
|
|
## ProxyProtocol
|
|
|
|
Traefik supports [ProxyProtocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt).
|
|
|
|
??? example "Enabling Proxy Protocol with Trusted IPs"
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.web.proxyProtocol]
|
|
trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
|
|
```
|
|
|
|
IPs in `trustedIPs` only will lead to remote client address replacement: Declare load-balancer IPs or CIDR range here.
|
|
|
|
??? example "Insecure Mode -- Testing Environment Only"
|
|
|
|
In a test environments, you can configure Traefik to trust every incoming connection.
|
|
Doing so, every remote client address will be replaced (`trustedIPs` won't have any effect)
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.web.proxyProtocol]
|
|
insecure = true
|
|
```
|
|
|
|
!!! 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).
|
|
|
|
## Forwarded Header
|
|
|
|
You can configure Traefik to trust the forwarded headers information (`X-Forwarded-*`)
|
|
|
|
??? example "Trusting Forwarded Headers from specific IPs"
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.web.forwardedHeaders]
|
|
trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
|
|
```
|
|
|
|
??? example "Insecure Mode -- Always Trusting Forwarded Headers"
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.web]
|
|
address = ":80"
|
|
|
|
[entryPoints.web.forwardedHeaders]
|
|
insecure = true
|
|
```
