文件后端

类似其他的反向代理工具，Træfɪk也可以使用文件来配置。你有两种选择：

  • 在全局配置文件 traefik.toml 后追加你的配置： 
  1. # traefik.toml
  2. logLevel = "DEBUG"
  3. defaultEntryPoints = ["http", "https"]
  4. [entryPoints]
  5.   [entryPoints.http]
  6.   address = ":80"
  7.     [entryPoints.http.redirect]
  8.       entryPoint = "https"
  9.   [entryPoints.https]
  10.   address = ":443"
  11.     [entryPoints.https.tls]
  12.       [[entryPoints.https.tls.certificates]]
  13.       CertFile = "integration/fixtures/https/snitest.com.cert"
  14.       KeyFile = "integration/fixtures/https/snitest.com.key"
  15.       [[entryPoints.https.tls.certificates]]
  16.       CertFile = "integration/fixtures/https/snitest.org.cert"
  17.       KeyFile = "integration/fixtures/https/snitest.org.key"
  19. [file]
  21. # rules
  22. [backends]
  23.   [backends.backend1]
  24.     [backends.backend1.circuitbreaker]
  25.       expression = "NetworkErrorRatio() > 0.5"
  26.     [backends.backend1.servers.server1]
  27.     url = "http://172.17.0.2:80"
  28.     weight = 10
  29.     [backends.backend1.servers.server2]
  30.     url = "http://172.17.0.3:80"
  31.     weight = 1
  32.   [backends.backend2]
  33.     [backends.backend1.maxconn]
  34.       amount = 10
  35.       extractorfunc = "request.host"
  36.     [backends.backend2.LoadBalancer]
  37.       method = "drr"
  38.     [backends.backend2.servers.server1]
  39.     url = "http://172.17.0.4:80"
  40.     weight = 1
  41.     [backends.backend2.servers.server2]
  42.     url = "http://172.17.0.5:80"
  43.     weight = 2
  45. [frontends]
  46.   [frontends.frontend1]
  47.   backend = "backend2"
  48.     [frontends.frontend1.routes.test_1]
  49.     rule = "Host:test.localhost"
  50.   [frontends.frontend2]
  51.   backend = "backend1"
  52.   passHostHeader = true
  53.   priority = 10
  54.   entrypoints = ["https"] # 覆盖 defaultEntryPoints
  55.     [frontends.frontend2.routes.test_1]
  56.     rule = "Host:{subdomain:[a-z]+}.localhost"
  57.   [frontends.frontend3]
  58.   entrypoints = ["http", "https"] # 覆盖 defaultEntryPoints
  59.   backend = "backend2"
  60.     rule = "Path:/test"
  • 或者将你的规则分割成独立的文件，例如 rules.toml： 
  1. # traefik.toml
  2. logLevel = "DEBUG"
  3. [entryPoints]
  4.   [entryPoints.http]
  5.   address = ":80"
  6.     [entryPoints.http.redirect]
  7.       entryPoint = "https"
  8.   [entryPoints.https]
  9.   address = ":443"
  10.     [entryPoints.https.tls]
  11.       [[entryPoints.https.tls.certificates]]
  12.       CertFile = "integration/fixtures/https/snitest.com.cert"
  13.       KeyFile = "integration/fixtures/https/snitest.com.key"
  14.       [[entryPoints.https.tls.certificates]]
  15.       CertFile = "integration/fixtures/https/snitest.org.cert"
  16.       KeyFile = "integration/fixtures/https/snitest.org.key"
  18. [file]
  19. filename = "rules.toml"
  1. # rules.toml
  2. [backends]
  3.   [backends.backend1]
  4.     [backends.backend1.circuitbreaker]
  5.       expression = "NetworkErrorRatio() > 0.5"
  6.     [backends.backend1.servers.server1]
  7.     url = "http://172.17.0.2:80"
  8.     weight = 10
  9.     [backends.backend1.servers.server2]
  10.     url = "http://172.17.0.3:80"
  11.     weight = 1
  12.   [backends.backend2]
  13.     [backends.backend1.maxconn]
  14.       amount = 10
  15.       extractorfunc = "request.host"
  16.     [backends.backend2.LoadBalancer]
  17.       method = "drr"
  18.     [backends.backend2.servers.server1]
  19.     url = "http://172.17.0.4:80"
  20.     weight = 1
  21.     [backends.backend2.servers.server2]
  22.     url = "http://172.17.0.5:80"
  23.     weight = 2
  25. [frontends]
  26.   [frontends.frontend1]
  27.   backend = "backend2"
  28.     [frontends.frontend1.routes.test_1]
  29.     rule = "Host:test.localhost"
  30.   [frontends.frontend2]
  31.   backend = "backend1"
  32.   passHostHeader = true
  33.   priority = 10
  34.   entrypoints = ["https"] # overrides defaultEntryPoints
  35.     [frontends.frontend2.routes.test_1]
  36.     rule = "Host:{subdomain:[a-z]+}.localhost"
  37.   [frontends.frontend3]
  38.   entrypoints = ["http", "https"] # overrides defaultEntryPoints
  39.   backend = "backend2"
  40.     rule = "Path:/test"

如果你希望 Træfɪk 动态监测这些文件的变化，只需添加：

  1. [file]
  2. watch = true
