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 at eBay in Amsterdam. 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 SSL, TCP proxy, TCP+SNI proxy (full end-to-end TLS), Websockets, SSE, dynamic reloading, traffic shaping for "blue/green" deployments, Circonus metrics, Graphite metrics, StatsD/DataDog metrics, WebUI and more.
Watch Kelsey Hightower demo Consul, Nomad, Vault and fabio at HashiConf EU 2016.
The full documentation is on the Wiki.
Getting started
-
Install from source, binary, Docker or Homebrew.
# go 1.8 or higher is required go get github.com/eBay/fabio (>= go1.8) brew install fabio (OSX/macOS stable) brew install --devel fabio (OSX/macOS devel) docker pull magiconair/fabio (Docker) https://github.com/eBay/fabio/releases (pre-built binaries) -
Register your service in consul.
Make sure that each instance registers with a unique ServiceID.
-
Register a health check in consul as described here.
Make sure the health check is passing since fabio will only watch services which have a passing health check.
-
Register one
urlprefix-tag perhost/pathprefix 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 # route with path stripping (forward only '/bar' to upstream)
# TCP examples
urlprefix-:3306 proto=tcp # route external port 3306
Make sure the prefix for HTTP routes contains at least one slash (/).
-
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. -
Send all your HTTP traffic to fabio on port
9999. For TCP proxying see TCP proxy. -
Done
