fabio is a fast, modern, zero-conf load balancing HTTP(S) and TCP router for deploying applications managed by consul.

Register your services in consul, provide a health check and fabio will start routing traffic to them. No configuration required. Deployment, upgrading and refactoring has never been easier.

fabio is developed and maintained by Frank Schroeder.

It powers some of the largest websites in The Netherlands (marktplaats.nl), Australia (gumtree.com.au) and Italy (www.kijiji.it). It delivers 23.000 req/sec every day since Sep 2015 without problems.

It integrates with Consul, Vault, Amazon ELB, Amazon API Gateway and more.

It supports (Full feature list)

Watch Kelsey Hightower demo Consul, Nomad, Vault and fabio at HashiConf EU 2016.

The full documentation is on fabiolb.net

Getting started

  1. Install from source, binary, Docker or Homebrew.

    # go 1.9 or higher is required
    go get github.com/fabiolb/fabio                     (>= go1.9)
    
    brew install fabio                                  (OSX/macOS stable)
    brew install --devel fabio                          (OSX/macOS devel)
    
    docker pull fabiolb/fabio                           (Docker)
    
    https://github.com/fabiolb/fabio/releases           (pre-built binaries)
  2. Register your service in consul.

    Make sure that each instance registers with a unique ServiceID and a service name without spaces.

  3. Register a health check in consul as described here.

    By default fabio only watches services which have a passing health check, unless overriden with registry.consul.service.status.

  4. Register one urlprefix- tag per host/path prefix it serves, e.g.:

# HTTP/S examples
urlprefix-/css                                     # path route
urlprefix-i.com/static                             # host specific path route
urlprefix-mysite.com/                              # host specific catch all route
urlprefix-/foo/bar strip=/foo                      # path stripping (forward '/bar' to upstream)
urlprefix-/foo/bar proto=https                     # HTTPS upstream
urlprefix-/foo/bar proto=https tlsskipverify=true  # HTTPS upstream and self-signed cert

# TCP examples
urlprefix-:3306 proto=tcp                          # route external port 3306

Make sure the prefix for HTTP routes contains at least one slash (/).

See the full list of options in the Documentation.

  1. Start fabio without a config file (assuming a running consul agent on localhost:8500) Watch the log output how fabio picks up the route to your service. Try starting/stopping your service to see how the routing table changes instantly.

  2. Send all your HTTP traffic to fabio on port 9999. For TCP proxying see TCP proxy.

  3. Done
