# Argo Tunnel client
Contains the command-line client for Argo Tunnel, a tunneling daemon that proxies any local webserver through the Cloudflare network. Extensive documentation can be found in the [Argo Tunnel section](https://developers.cloudflare.com/argo-tunnel/) of the Cloudflare Docs.
Contains the command-line client and its libraries for Argo Tunnel, a tunneling daemon that proxies any local webserver through the Cloudflare network.
## Before you get started
## Getting started
Before you use Argo Tunnel, you'll need to complete a few steps in the Cloudflare dashboard. The website you add to Cloudflare will be used to route traffic to your Tunnel.
1. [Add a website to Cloudflare](https://support.cloudflare.com/hc/en-us/articles/201720164-Creating-a-Cloudflare-account-and-adding-a-website)
2. [Change your domain nameservers to Cloudflare](https://support.cloudflare.com/hc/en-us/articles/205195708)
## Installing `cloudflared`
Downloads are available as standalone binaries, a Docker image, and Debian, RPM, and Homebrew packages. You can also find releases here on the `cloudflared` GitHub repository.
* You can [install on macOS](https://developers.cloudflare.com/argo-tunnel/getting-started/installation#macos) via Homebrew or by downloading the [latest Darwin amd64 release](https://github.com/cloudflare/cloudflared/releases)
* Binaries, Debian, and RPM packages for Linux [can be found here](https://developers.cloudflare.com/argo-tunnel/getting-started/installation#linux)
* A Docker image of `cloudflared` is [available on DockerHub](https://hub.docker.com/r/cloudflare/cloudflared)
* You can install on Windows machines with the [steps here](https://developers.cloudflare.com/argo-tunnel/getting-started/installation#windows)
go install github.com/cloudflare/cloudflared/cmd/cloudflared
User documentation for Argo Tunnel can be found at https://developers.cloudflare.com/argo-tunnel/
## Creating Tunnels and routing traffic
Once installed, you can authenticate `cloudflared` into your Cloudflare account and begin creating Tunnels that serve traffic for hostnames in your account.
* Create a Tunnel with [these instructions](https://developers.cloudflare.com/argo-tunnel/create-tunnel)
* Route traffic to that Tunnel with [DNS records in Cloudflare](https://developers.cloudflare.com/argo-tunnel/routing-to-tunnel/dns) or with a [Cloudflare Load Balancer](https://developers.cloudflare.com/argo-tunnel/routing-to-tunnel/lb)
## TryCloudflare
Want to test Argo Tunnel before adding a website to Cloudflare? You can do so with TryCloudflare using the documentation [available here](https://developers.cloudflare.com/argo-tunnel/learning/trycloudflare).
## Deprecated versions
Cloudflare currently supports all versions of `cloudflared`. Starting on March 20, 2021, Cloudflare will no longer support versions released prior to 2020.5.1.
All features available in versions released prior to 2020.5.1 are available in current versions. Breaking changes unrelated to feature availability may be introduced that will impact versions released prior to 2020.5.1. You can read more about upgrading `cloudflared` in our [developer documentation](https://developers.cloudflare.com/argo-tunnel/getting-started/installation#updating-cloudflared).
| Version(s) | Deprecation status |
|---|---|
| 2020.5.1 and later | Supported |
| Versions prior to 2020.5.1 | Will no longer be supported starting March 20, 2021 |

Description: ` Cloudflared lets you route traffic from the internet to multiple different addresses on your
origin. Multiple-origin routing is configured by a set of rules. Each rule matches traffic
by its hostname or path, and routes it to an address. These rules are configured under the
'ingress' key of your config.yaml, for example:
ingress:
- hostname: www.example.com
service: https://localhost:8000
- hostname: *.example.xyz
path: /[a-zA-Z]+.html
service: https://localhost:8001
- hostname: *
service: https://localhost:8002
To ensure cloudflared can route all incoming requests, the last rule must be a catch-all
rule that matches all traffic. You can validate these rules with the 'ingress validate'
command, and test which rule matches a particular URL with 'ingress rule <URL>'.
Multiple-origin routing is incompatible with the --url flag.`,
