Bondy is an open source, always-on and scalable application networking platform for modern architectures. It is an all-in-one event and service mesh that offers both Publish-Subscribe (PubSub) and routed Remote Procedure Calls (RPC). Bondy implements the open Web Application Messaging Protocol (WAMP) and is written in Erlang.

Bondy

The distributed application networking platform

Bondy is an open source, always-on and scalable application networking platform for modern distributed architectures. It is an all-in-one event and service mesh with support for multiple communication patterns, multiple protocols and secure multi-tenancy.

Bondy implements the open Web Application Messaging Protocol (WAMP) offering both Publish and Subscribe (PubSub) and routed Remote Procedure Calls (RPC) communication patterns.

Quick Start

Docker

The fastest way to get started is by using our official docker images.

1. Make sure you have Docker installed and running.
2. Download the examples/custom_config folder to a location of your choice, then cd to that location and run the following command (If you already cloned the Bondy repository then just cd to the location of the repo).

docker run \
--rm \
-e [email protected] \
-e BONDY_ERL_DISTRIBUTED_COOKIE=bondy \
-u 0:1000 \
-p 18080:18080 \
-p 18081:18081 \
-p 18082:18082 \
-p 18083:18083 \
-p 18084:18084 \
-p 18085:18085 \
-v "$(PWD)/examples/custom_config/etc:/bondy/etc" \
-v "/tmp/data:/bondy/data" \
leapsight/bondy:master

Building from source

Requirements

• Erlang 24 or later
• Rebar3 3.17.0 or later
• openssl
• libssl
• Libsodium
• libsnappy
• liblz4

Building

Clone this repository and cd to the location where you cloned it.

To generate a Bondy release to be used in production execute the following command which will generate a tarball containing the release at $(PWD)/_build/prod/rel/.

rebar3 as prod tar

Untar and copy the resulting tarball to the location where you want to install Bondy e.g. ~/tmp/bondy.

tar -zxvf _build/prod/rel/bondy-1.0.0-beta.28.tar.qz -C ~/tmp/bondy

Running

To run Bondy, cd to the location where you installed it e.g. ~/tmp/bondy and run the following command which will print all the options.

bin/bondy

For example, to run Bondy with output to stdout do

bin/bondy foreground

And to run Bondy with an interactive Erlang shell do

bin/bondy console

Local cluster testing

Run a first node

We will start a node named [email protected] which uses the following variables from the config file (config/test/node_1_vars.config).

Transport	Description	Port
HTTP	REST API GATEWAY	18080
HTTP	REST API GATEWAY	18083
HTTP	REST Admin API	18081
HTTPS	REST Admin API	18084
Websockets	WAMP	18080
TCP	WAMP Raw Socket	18082
TLS	WAMP Raw Socket	18085

make node1

Create a Realm

WAMP is a session-based protocol. Each session belongs to a Realm.

curl -X "POST" "http://localhost:18081/realms/" \
     -H 'Content-Type: application/json; charset=utf-8' \
     -H 'Accept: application/json; charset=utf-8' \
     -d $'{
  "uri": "com.myrealm",
  "description": "My First Realm"
}'

Disable Security

We will disable security to avoid setting up credentials at this moment.

curl -X "DELETE" "http://localhost:18081/realms/com.myrealm/security_enabled" \
     -H 'Content-Type: application/json; charset=utf-8' \
     -H 'Accept: application/json; charset=utf-8'

Run a second node

We start a second node named [email protected] which uses the following variables from the config file (config/test/node_2_vars.config).

Transport	Description	Port
HTTP	REST API GATEWAY	18180
HTTP	REST API GATEWAY	18183
HTTP	REST Admin API	18181
HTTPS	REST Admin API	18184
Websockets	WAMP	18180
TCP	WAMP Raw Socket	18182
TLS	WAMP Raw Socket	18185

make node2

After a minute the two nodes will automatically connect. From now on all new Bondy control plane state changes will be propagated in real-time through broadcasting. One minute after joining the cluster, the Active Anti-entropy service will trigger an exchange after which the Realm we have created in [email protected] will have been replicated to [email protected].

Run a third node

make node3
