moxy

moxy is a HTTP Reverse Proxy and Load Balancer that automatically configures itself for microservices deployed on Apache Mesos and Marathon. It is inspired by Vulcand and moxy does in fact use the same proxy library written by the nice people at Mailgun.

UPDATE (2016/02/12): moxy development is being greatly reduced in favor of nixy which replaces moxy completely

Features:

• Reverse proxy and load balancer for your microservices running inside Mesos and Marathon
• Single binary with no other dependencies for easy deployment
• Supports TLS termination
• Statistics of req/s per application via statsd
• Event callback listener to automatically be up-to-date with Marathon
• Local file backups of Marathon states, so moxy will keep serving your apps even if Marathon goes down or across restarts.
• • more on the works...

Compatibility

Tested againts Marathon 0.8.1<->0.13.0 and Mesos 0.22<->0.26

Getting started

1. Easiest is to install moxy from pre-compiled packages. Check releases page.

2. Edit config (default on ubuntu is /etc/moxy.toml):

# moxy listening port
port = "7000"

# optional X-Proxy header name
xproxy = "hostname"

# marathon api
marathon = "http://localhost:8080"

# statsd settings
statsd = "localhost:8125" # optional if you want to graph req/s per app
prefix = "moxy."

# tls settings
tls = false # optional if you want moxy to terminate tls
cert = "cert.pem"
key = "key.pem"

3. Add the moxy url + /moxy_callback to your callbacks in Marathon.

4. Run moxy!

Using Moxy

Routing is based on the HTTP Host header matching app.* Example: app.example.com and app.example.org both route to the same tasks running that app.

Example to access your apps app1,app2,app3 running in Mesos and Marathon:

curl -i localhost:7000/ -H 'Host: app1.example.com'
curl -i localhost:7000/ -H 'Host: app2.example.com'
curl -i localhost:7000/ -H 'Host: app3.example.com'

To set custom subdomain for an application

Deploy your app to Marathon setting a custom label called moxy_subdomain:

"labels": {
    "moxy_subdomain": "foobar"
},

This will override the application name and replace it with foobar as the new subdomain/host-header.
