# 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](../reference/entrypoints.md) for the list of available options.
|
|
|
|
??? example "Using the CLI"
|
|
|
|
Here is an example of using the CLI to define `entrypoints`:
|
|
|
|
```shell
|
|
--entryPoints='Name:http Address::80'
|
|
--entryPoints='Name:https Address::443'
|
|
```
|
|
|
|
!!! note
|
|
The whitespace character (` `) is the option separator, and the comma (`,`) is the value separator for lists.
|
|
The option names are case-insensitive.
|
|
|
|
!!! warning "Using Docker Compose Files"
|
|
|
|
The syntax for passing arguments inside a docker compose file is a little different. Here are two examples.
|
|
|
|
```yaml
|
|
traefik:
|
|
image: traefik:v2.0 # The official v2.0 Traefik docker image
|
|
command:
|
|
- --defaultentrypoints=powpow
|
|
- "--entryPoints=Name:powpow Address::42 Compress:true"
|
|
```
|
|
|
|
or
|
|
|
|
```yaml
|
|
traefik:
|
|
image: traefik:v2.0 # The official v2.0 Traefik docker image
|
|
command: --defaultentrypoints=powpow --entryPoints='Name:powpow Address::42 Compress:true'
|
|
```
|
|
|
|
## 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 Environnement 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
|
|
```
