### CLI
|
|
|
|
For more information about the CLI, see the documentation about [Traefik command](/basics/#traefik).
|
|
|
|
```shell
|
|
--entryPoints='Name:http Address::80'
|
|
--entryPoints='Name:https Address::443 TLS'
|
|
```
|
|
|
|
!!! note
|
|
Whitespace is used as option separator and `,` is used as value separator for the list.
|
|
The names of the options are case-insensitive.
|
|
|
|
In compose file the entrypoint syntax is different:
|
|
|
|
```yaml
|
|
traefik:
|
|
image: traefik
|
|
command:
|
|
- --defaultentrypoints=powpow
|
|
- "--entryPoints=Name:powpow Address::42 Compress:true"
|
|
```
|
|
or
|
|
```yaml
|
|
traefik:
|
|
image: traefik
|
|
command: --defaultentrypoints=powpow --entryPoints='Name:powpow Address::42 Compress:true'
|
|
```
|
|
|
|

## Basic
|
|
|
|
```toml
|
|
# Entrypoints definition
|
|
#
|
|
# Default:
|
|
# [entryPoints]
|
|
# [entryPoints.http]
|
|
# address = ":80"
|
|
#
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
```
|
|
|
|
## Redirect HTTP to HTTPS
|
|
|
|
To redirect an http entrypoint to an https entrypoint (with SNI support).
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
[entryPoints.http.redirect]
|
|
entryPoint = "https"
|
|
[entryPoints.https]
|
|
address = ":443"
|
|
[entryPoints.https.tls]
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.org.cert"
|
|
keyFile = "integration/fixtures/https/snitest.org.key"
|
|
```
|
|
|
|
!!! note
|
|
Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an entrypoint is defined for the redirection (they will not be used in this case).
|
|
|
|
## Rewriting URL
|
|
|
|
To redirect an entrypoint rewriting the URL.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
[entryPoints.http.redirect]
|
|
regex = "^http://localhost/(.*)"
|
|
replacement = "http://mydomain/$1"
|
|
```
|
|
|
|
!!! note
|
|
Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an `entrypoint` is defined for the redirection (they will not be used in this case).
|
|
|
|
Care should be taken when defining replacement expand variables: `$1x` is equivalent to `${1x}`, not `${1}x` (see [Regexp.Expand](https://golang.org/pkg/regexp/#Regexp.Expand)), so use `${1}` syntax.
|
|
|
|
Regular expressions and replacements can be tested using online tools such as [Go Playground](https://play.golang.org/p/mWU9p-wk2ru) or the [Regex101](https://regex101.com/r/58sIgx/2).
|
|
|
|
## TLS
|
|
|
|
### Static Certificates
|
|
|
|
Define an entrypoint with SNI support.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.https]
|
|
address = ":443"
|
|
[entryPoints.https.tls]
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
```
|
|
|
|
!!! note
|
|
If an empty TLS configuration is done, default self-signed certificates are generated.
|
|
|
|
|
|
### Dynamic Certificates
|
|
|
|
If you need to add or remove TLS certificates while Traefik is started, Dynamic TLS certificates are supported using the [file provider](/configuration/backends/file).
|
|
|
|
|
|
## TLS Mutual Authentication
|
|
|
|
TLS Mutual Authentication can be `optional` or not.
|
|
If it's `optional`, Træfik will authorize connection with certificates not signed by a specified Certificate Authority (CA).
|
|
Otherwise, Træfik will only accept clients that present a certificate signed by a specified Certificate Authority (CA).
|
|
`ClientCAFiles` can be configured with multiple `CA:s` in the same file or use multiple files containing one or several `CA:s`.
|
|
The `CA:s` has to be in PEM format.
|
|
|
|
By default, `ClientCAFiles` is not optional, all clients will be required to present a valid cert.
|
|
The requirement will apply to all server certs in the entrypoint.
|
|
|
|
In the example below both `snitest.com` and `snitest.org` will require client certs
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.https]
|
|
address = ":443"
|
|
[entryPoints.https.tls]
|
|
[entryPoints.https.tls.ClientCA]
|
|
files = ["tests/clientca1.crt", "tests/clientca2.crt"]
|
|
optional = false
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.org.cert"
|
|
keyFile = "integration/fixtures/https/snitest.org.key"
|
|
```
|
|
|
|
!!! note
|
|
The deprecated argument `ClientCAFiles` allows adding Client CA files which are mandatory.
|
|
If this parameter exists, the new ones are not checked.
|
|
|
|
## Authentication
|
|
|
|
### Basic Authentication
|
|
|
|
Passwords can be encoded in MD5, SHA1 and BCrypt: you can use `htpasswd` to generate them.
|
|
|
|
Users can be specified directly in the TOML file, or indirectly by referencing an external file;
|
|
if both are provided, the two are merged, with external file contents having precedence.
|
|
|
|
```toml
|
|
# To enable basic auth on an entrypoint with 2 user/pass: test:test and test2:test2
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
[entryPoints.http.auth.basic]
|
|
users = ["test:$apr1$H6uskkkW$IgXLP6ewTrSuBkTrqE8wj/", "test2:$apr1$d9hr9HBB$4HxwgUir3HP4EsggP/QNo0"]
|
|
usersFile = "/path/to/.htpasswd"
|
|
```
|
|
|
|
### Digest Authentication
|
|
|
|
You can use `htdigest` to generate them.
|
|
|
|
Users can be specified directly in the TOML file, or indirectly by referencing an external file;
|
|
if both are provided, the two are merged, with external file contents having precedence
|
|
|
|
```toml
|
|
# To enable digest auth on an entrypoint with 2 user/realm/pass: test:traefik:test and test2:traefik:test2
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
[entryPoints.http.auth.digest]
|
|
users = ["test:traefik:a2688e031edb4be6a3797f3882655c05", "test2:traefik:518845800f9e2bfb1f1f740ec24f074e"]
|
|
usersFile = "/path/to/.htdigest"
|
|
```
|
|
|
|
### Forward Authentication
|
|
|
|
This configuration will first forward the request to `http://authserver.com/auth`.
|
|
|
|
If the response code is 2XX, access is granted and the original request is performed.
|
|
Otherwise, the response from the authentication server is returned.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
# ...
|
|
# To enable forward auth on an entrypoint
|
|
[entryPoints.http.auth.forward]
|
|
address = "https://authserver.com/auth"
|
|
|
|
# Trust existing X-Forwarded-* headers.
|
|
# Useful with another reverse proxy in front of Traefik.
|
|
#
|
|
# Optional
|
|
# Default: false
|
|
#
|
|
trustForwardHeader = true
|
|
|
|
# Enable forward auth TLS connection.
|
|
#
|
|
# Optional
|
|
#
|
|
[entryPoints.http.auth.forward.tls]
|
|
cert = "authserver.crt"
|
|
key = "authserver.key"
|
|
```
|
|
|
|
## Specify Minimum TLS Version
|
|
|
|
To specify an https entry point with a minimum TLS version, and specifying an array of cipher suites (from [crypto/tls](https://godoc.org/crypto/tls#pkg-constants)).
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.https]
|
|
address = ":443"
|
|
[entryPoints.https.tls]
|
|
minVersion = "VersionTLS12"
|
|
cipherSuites = [
|
|
"TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256",
|
|
"TLS_RSA_WITH_AES_256_GCM_SHA384"
|
|
]
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
[[entryPoints.https.tls.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.org.cert"
|
|
keyFile = "integration/fixtures/https/snitest.org.key"
|
|
```
|
|
|
|
## Compression
|
|
|
|
To enable compression support using gzip format.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
compress = true
|
|
```
|
|
|
|
Responses are compressed when:
|
|
|
|
* The response body is larger than `512` bytes
|
|
* And the `Accept-Encoding` request header contains `gzip`
|
|
* And the response is not already compressed, i.e. the `Content-Encoding` response header is not already set.
|
|
|
|
## White Listing
|
|
|
|
To enable IP white listing at the entry point level.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
|
|
[entryPoints.http]
|
|
sourceRange = ["127.0.0.1/32", "192.168.1.7"]
|
|
# useXForwardedFor = true
|
|
```
|
|
|
|
## ProxyProtocol
|
|
|
|
To enable [ProxyProtocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt) support.
|
|
Only IPs in `trustedIPs` will lead to remote client address replacement: you should declare your load-balancer IP or CIDR range here (in testing environment, you can trust everyone using `insecure = true`).
|
|
|
|
!!! danger
|
|
When queuing Træfik behind another load-balancer, be sure to carefully configure Proxy Protocol on both sides.
|
|
Otherwise, it could introduce a security risk in your system by forging requests.
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
|
|
# Enable ProxyProtocol
|
|
[entryPoints.http.proxyProtocol]
|
|
# List of trusted IPs
|
|
#
|
|
# Required
|
|
# Default: []
|
|
#
|
|
trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
|
|
|
|
# Insecure mode FOR TESTING ENVIRONNEMENT ONLY
|
|
#
|
|
# Optional
|
|
# Default: false
|
|
#
|
|
# insecure = true
|
|
```
|
|
|
|
## Forwarded Header
|
|
|
|
Only IPs in `trustedIPs` will be authorized to trust the client forwarded headers (`X-Forwarded-*`).
|
|
|
|
```toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
|
|
# Enable Forwarded Headers
|
|
[entryPoints.http.forwardedHeaders]
|
|
# List of trusted IPs
|
|
#
|
|
# Required
|
|
# Default: []
|
|
#
|
|
trustedIPs = ["127.0.0.1/32", "192.168.1.7"]
|
|
```
|
