#### Notes
1) From release 1.6.1 onward, the minimum golang version supported is 1.16.
2) From release 1.6.0 onward, metrics backend statsd is no longer supported. statsd_raw
works similarly, though it actually resets counters appropriately. If you are using datadog,
you should consider using the new dogstatsd backend, which has support for tags now. Graphite
histogram functionality has changed slightly since switching to gokit framework, so something to be aware of.
Prometheus functionality is now supported natively.
3) From release 1.5.15 onward, fabio changes the default GOGC from 800 back to
the golang default of 100. Apparently this made some sense back in the golang 1.5 days, but with
changes introduced with golang 1.12 and others, this is probably no longer a very good default.
This is still configurable, as always, but the new default should make the most sense for most users.
4) From release 1.5.14, release hashes are signed with a new PGP key.
See details [here](https://fabiolb.net/faq/verifying-releases/).
5) From release 1.5.14 onward, fabio binary releases are compiled with golang 1.15+.
This means that the fabio will no longer validate upstream https certificates that do
not have SAN extensions matching the server name. This may be a concern if fabio is
communicating with https backends with misconfigured certificates. If this is a problem,
you can specify `tlsskipverify=true` on the route.

fabio is a fast, modern, zero-conf load balancing HTTP(S) and TCP router
for deploying applications managed by [consul](https://consul.io/).
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 The Fabio Authors.
It powers some of the largest websites in
Australia ([gumtree.com.au](http://www.gumtree.com.au))
and Italy ([www.kijiji.it](http://www.kijiji.it/)).
It delivers 23.000 req/sec every day since Sep 2015 without problems.
It integrates with
[Consul](https://consul.io/),
[Vault](https://vaultproject.io/),
[Amazon ELB](https://aws.amazon.com/elasticloadbalancing),
[Amazon API Gateway](https://aws.amazon.com/api-gateway/)
and more.
It supports ([Full feature list](https://fabiolb.net/feature/))
* [TLS termination with dynamic certificate stores](https://fabiolb.net/feature/certificate-stores/)
* [Raw TCP proxy](https://fabiolb.net/feature/tcp-proxy/)
* [TCP+SNI proxy for full end-to-end TLS](https://fabiolb.net/feature/tcp-sni-proxy/) without decryption
* [HTTPS+TCP+SNI proxy for TCP+SNI with HTTPS fallback](https://fabiolb.net/feature/https-tcp-sni-proxy/)
* [TCP dynamic proxy](https://fabiolb.net/feature/tcp-dynamic-proxy/)
* [HTTPS upstream support](https://fabiolb.net/feature/https-upstream/)
* [Websockets](https://fabiolb.net/feature/websockets/) and
* [SSE](https://fabiolb.net/feature/sse/)
* [Dynamic reloading without restart](https://fabiolb.net/feature/dynamic-reloading/)
* [Traffic shaping](https://fabiolb.net/feature/traffic-shaping/) for "blue/green" deployments,
* [Prometheus](https://fabiolb.net/feature/metrics/),
* [Circonus](https://fabiolb.net/feature/metrics/),
* [Graphite](https://fabiolb.net/feature/metrics/),
* [StatsD](https://fabiolb.net/feature/metrics/),
* [DataDog](https://fabiolb.net/feature/metrics/) for metrics,
* [WebUI](https://fabiolb.net/feature/web-ui/) and
* [Advertising BGP anycast addresses](https://fabiolb.net/feature/bgp/) on non-windows platforms.

## Getting started
1. Install from source, [binary](https://github.com/fabiolb/fabio/releases),
[Docker](https://hub.docker.com/r/fabiolb/fabio/) or [Homebrew](http://brew.sh).
```shell
# go 1.15 or higher is required
go install github.com/fabiolb/fabio@latest (>= go1.15)
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](https://consul.io/).
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](https://consul.io/docs/agent/checks.html).
By default fabio only watches services which have a **passing** health check, unless overridden with [registry.consul.service.status](https://fabiolb.net/ref/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](https://github.com/fabiolb/fabio/wiki/Routing#config-language).
5. 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.
6. Send all your HTTP traffic to fabio on port `9999`.
For TCP proxying see [TCP proxy](https://fabiolb.net/feature/tcp-proxy/).
7. Done
