# File Backends
|
|
|
|
Like any other reverse proxy, Træfik can be configured with a file.
|
|
|
|
You have three choices:
|
|
|
|
- [Simple](/configuration/backends/file/#simple)
|
|
- [Rules in a Separate File](/configuration/backends/file/#rules-in-a-separate-file)
|
|
- [Multiple `.toml` Files](/configuration/backends/file/#multiple-toml-files)
|
|
|
|
To enable the file backend, you must either pass the `--file` option to the Træfik binary or put the `[file]` section (with or without inner settings) in the configuration file.
|
|
|
|
The configuration file allows managing both backends/frontends and HTTPS certificates (which are not [Let's Encrypt](https://letsencrypt.org) certificates generated through Træfik).
|
|
|
|
## Simple
|
|
|
|
Add your configuration at the end of the global configuration file `traefik.toml`:
|
|
|
|
```toml
|
|
defaultEntryPoints = ["http", "https"]
|
|
|
|
[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.org.cert"
|
|
keyFile = "integration/fixtures/https/snitest.org.key"
|
|
|
|
[file]
|
|
|
|
# rules
|
|
[backends]
|
|
[backends.backend1]
|
|
[backends.backend1.circuitbreaker]
|
|
expression = "NetworkErrorRatio() > 0.5"
|
|
[backends.backend1.servers.server1]
|
|
url = "http://172.17.0.2:80"
|
|
weight = 10
|
|
[backends.backend1.servers.server2]
|
|
url = "http://172.17.0.3:80"
|
|
weight = 1
|
|
[backends.backend2]
|
|
[backends.backend2.maxconn]
|
|
amount = 10
|
|
extractorfunc = "request.host"
|
|
[backends.backend2.LoadBalancer]
|
|
method = "drr"
|
|
[backends.backend2.servers.server1]
|
|
url = "http://172.17.0.4:80"
|
|
weight = 1
|
|
[backends.backend2.servers.server2]
|
|
url = "http://172.17.0.5:80"
|
|
weight = 2
|
|
|
|
[frontends]
|
|
[frontends.frontend1]
|
|
backend = "backend2"
|
|
[frontends.frontend1.routes.test_1]
|
|
rule = "Host:test.localhost"
|
|
|
|
[frontends.frontend2]
|
|
backend = "backend1"
|
|
passHostHeader = true
|
|
priority = 10
|
|
|
|
# restrict access to this frontend to the specified list of IPv4/IPv6 CIDR Nets
|
|
# an unset or empty list allows all Source-IPs to access
|
|
# if one of the Net-Specifications are invalid, the whole list is invalid
|
|
# and allows all Source-IPs to access.
|
|
whitelistSourceRange = ["10.42.0.0/16", "152.89.1.33/32", "afed:be44::/16"]
|
|
|
|
entrypoints = ["https"] # overrides defaultEntryPoints
|
|
[frontends.frontend2.routes.test_1]
|
|
rule = "Host:{subdomain:[a-z]+}.localhost"
|
|
|
|
[frontends.frontend3]
|
|
entrypoints = ["http", "https"] # overrides defaultEntryPoints
|
|
backend = "backend2"
|
|
rule = "Path:/test"
|
|
|
|
# HTTPS certificate
|
|
[[tlsConfiguration]]
|
|
entryPoints = ["https"]
|
|
[tlsConfiguration.certificate]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
```
|
|
|
|
!!! note
|
|
adding certificates directly to the entrypoint is still maintained but certificates declared in this way cannot be managed dynamically.
|
|
It's recommended to use the file provider to declare certificates.
|
|
|
|
## Rules in a Separate File
|
|
|
|
Put your rules in a separate file, for example `rules.toml`:
|
|
|
|
```toml
|
|
# traefik.toml
|
|
[entryPoints]
|
|
[entryPoints.http]
|
|
address = ":80"
|
|
[entryPoints.http.redirect]
|
|
entryPoint = "https"
|
|
[entryPoints.https]
|
|
address = ":443"
|
|
[entryPoints.https.tls]
|
|
|
|
[file]
|
|
filename = "rules.toml"
|
|
```
|
|
|
|
```toml
|
|
# rules.toml
|
|
[backends]
|
|
[backends.backend1]
|
|
[backends.backend1.circuitbreaker]
|
|
expression = "NetworkErrorRatio() > 0.5"
|
|
[backends.backend1.servers.server1]
|
|
url = "http://172.17.0.2:80"
|
|
weight = 10
|
|
[backends.backend1.servers.server2]
|
|
url = "http://172.17.0.3:80"
|
|
weight = 1
|
|
[backends.backend2]
|
|
[backends.backend2.maxconn]
|
|
amount = 10
|
|
extractorfunc = "request.host"
|
|
[backends.backend2.LoadBalancer]
|
|
method = "drr"
|
|
[backends.backend2.servers.server1]
|
|
url = "http://172.17.0.4:80"
|
|
weight = 1
|
|
[backends.backend2.servers.server2]
|
|
url = "http://172.17.0.5:80"
|
|
weight = 2
|
|
|
|
[frontends]
|
|
[frontends.frontend1]
|
|
backend = "backend2"
|
|
[frontends.frontend1.routes.test_1]
|
|
rule = "Host:test.localhost"
|
|
[frontends.frontend2]
|
|
backend = "backend1"
|
|
passHostHeader = true
|
|
priority = 10
|
|
entrypoints = ["https"] # overrides defaultEntryPoints
|
|
[frontends.frontend2.routes.test_1]
|
|
rule = "Host:{subdomain:[a-z]+}.localhost"
|
|
[frontends.frontend3]
|
|
entrypoints = ["http", "https"] # overrides defaultEntryPoints
|
|
backend = "backend2"
|
|
rule = "Path:/test"
|
|
|
|
# HTTPS certificate
|
|
[[tlsConfiguration]]
|
|
entryPoints = ["https"]
|
|
[tlsConfiguration.certificate]
|
|
certFile = "integration/fixtures/https/snitest.com.cert"
|
|
keyFile = "integration/fixtures/https/snitest.com.key"
|
|
|
|
[[tlsConfiguration]]
|
|
entryPoints = ["https"]
|
|
[[tlsConfiguration.certificates]]
|
|
certFile = "integration/fixtures/https/snitest.org.cert"
|
|
keyFile = "integration/fixtures/https/snitest.org.key"
|
|
```
|
|
|
|
## Multiple `.toml` Files
|
|
|
|
You could have multiple `.toml` files in a directory (and recursively in its sub-directories):
|
|
|
|
```toml
|
|
[file]
|
|
directory = "/path/to/config/"
|
|
```
|
|
|
|
If you want Træfik to watch file changes automatically, just add:
|
|
|
|
```toml
|
|
[file]
|
|
watch = true
|
|
```
