Configuration

StaticUpdate

[pilot]
    token="xxx"

[experimental.plugins.blockuseragent]
    modulename = "github.com/agence-gaya/traefik-plugin-blockuseragent"
    version = "vX.Y.Z"

Dynamic

To configure the Block User-Agent plugin you should create a middleware in your dynamic configuration as explained here. The following example creates and uses the blockuseragent middleware plugin to block all HTTP requests with a User-Agent like \bTheAgent\b. You can use regexAllow to make exception on blocking regex.

[http.routers]
  [http.routers.my-router]
    rule = "Host(`localhost`)"
    middlewares = ["block-foo"]
    service = "my-service"

# Block all user agent containing TheAgent except if containing Allowed word
[http.middlewares]
  [http.middlewares.block-foo.plugin.blockuseragent]
    regexAllow = ["\bAllowed\b"]    
    regex = ["\bTheAgent\b"]

[http.services]
  [http.services.my-service]
    [http.services.my-service.loadBalancer]
      [[http.services.my-service.loadBalancer.servers]]
        url = "http://127.0.0.1"
