vproxy

vproxy

A zero-config service mesh for local development

Stop trying to remember port numbers and create secure endpoints for your services. Automatically updates your hosts file, generates TLS certificates, (via mkcert/truststore), and binds a reverse proxy with a single command.

No third-party dependencies. No Docker. No Kubernetes.

Quickstart

brew install jittering/kegs/vproxy
vproxy caroot --create
sudo brew services start vproxy
vproxy connect hello.local:8888 -- vproxy hello

Now open https://hello.local in your browser!

Installation

via homebrew (mac or linux):

brew install jittering/kegs/vproxy

or manually (macOS, linux, windows):

• Download a pre-built binary
• Install in proper location, e.g., /usr/local/bin/ or %SYSTEMROOT%\System32\

or build it from source:

go install github.com/jittering/vproxy/bin/vproxy@master

Initialize local root CA

Create and install a new local root CA in your system:

vproxy caroot --create

Usage

vproxy can run in two modes, depending on the use case: single-process for proxying a single service or with a standalone daemon for proxying more than one service.

vproxy consists of two processes: daemon and client.

• The daemon serves as the primary host of the HTTP & HTTPS endpoints for your applications.
• The client registers a service with the daemon and relays all access logs to the current terminal. It can also optionally run the service for you.

A single daemon is required per-host, while clients can be run multiple times.

In single-process mode, skip the daemon section.

daemon

If installed via homebrew on macOS, running it as a service is easy:

sudo brew services start vproxy

Note that you must run as root to bind to privileged ports (hence the use of sudo above).

Or run it manually:

$ vproxy daemon
[*] rerunning with sudo
Password:
[*] starting proxy: http://127.0.0.1:80
[*] starting proxy: https://127.0.0.1:443

client

Use the connect command to bind a hostname to a local port:

$ vproxy connect --bind foo.local.com:5000
[*] registering vhost: foo.local.com:5000

The daemon will automatically:

• Issue a TLS cert for foo.local.com
• Add foo.local.com to your hosts file (e.g., /etc/hosts)
• Add a reverse proxy vhost connecting foo.local.com to port 5000

You can even run the underlying service with one command, for ease of use:

$ vproxy connect --bind foo.local.com:5000 -- flask run
[*] running command: /usr/local/bin/flask run
[*] registering vhost: foo.local.com:5000
 * Serving Flask app "app/main.py"
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Now visit https://foo.local.com to access your application originally running on http://127.0.0.1:5000

When you stop the client process (i.e., by pressing ^C), vproxy will deregister the vhost with the daemon and send a TERM signal to it's child process.

Permissions

A couple of notes on permissions. The vproxy daemon must be run with elevated privileges for the following reasons:

• macOS or Linux: binding on privileged ports 80/443 and modifying /etc/hosts
• Windows: modifying %SYSTEMROOT%\System32\drivers\etc\hosts
• All: installing our local CA into the system trust stores (system prompt)

On mac or linux this means running as root (or via sudo).

On Windows this means running via an elevated command prompt.
