Examples:
aedes --protos tcp ws Starts Aedes broker with TCP and WS
servers
aedes --config myConfig.js Starts Aedes broker with custom
config file
aedes --stats -v --statsInterval 2000 Starts Aedes broker with stats
enabled
aedes --credentials ./credentials.json Add/Modify user1 with password1 to
adduser user1 password1 credentials
aedes --credentials ./credentials.json Removes user1 from credentials
rmuser user1
To fully use Aedes you need to define a configuration file where the communication broker is defined. Here follows an example using Mongodb.
A configuration file is structured in the following way:
module.exports = {
protos: ['tcp'],
host: '127.0.0.1',
port: 1883,
wsPort: 3000,
wssPort: 4000,
tlsPort: 8883,
brokerId: 'aedes-cli',
credentials: './credentials.json',
persistence: {
name: 'mongodb',
options: {
url: 'mongodb://127.0.0.1/aedes'
}
},
mq: {
name: 'mongodb',
options: {
url: 'mongodb://127.0.0.1/aedes'
}
},
key: null,
cert: null,
rejectUnauthorized: true,
verbose: false,
veryVerbose: false,
noPretty: false
}Docker
aedes-cli is available on Docker-Hub for amd64, arm64v8, arm32v6, arm32v7, i386 archs. If you want to use a local credentials.json file and/or a custom config file to pass using --config option you have to use docker volumes and map the local folder containing those files to a folder inside the container.
Example:
docker run --rm -it -p 1883:1883 -v $(pwd):/data moscajs/aedes:latest --config /data/myConfig.js
-v $(pwd):/datawill map the local folder from where you are running this command to/datafolder of the container--config /data/myConfig.jswill tell aedes to use the configuration file that is in your local folder
Here there is an example with docker-compose that runs aedes with mongodb as persistence
version: '3.7'
services:
aedes:
container_name: aedes
image: moscajs/aedes:latest
restart: always
stop_signal: SIGINT
networks:
- mqtt
command: --config /data/mongodbConfig.js # add here the options to pass to aedes
volumes:
- ./:/data # map the local folder to aedes
ports:
- '1883:1883'
- '3000:3000'
- '4000:4000'
- '8883:8883'
mongo:
container_name: mongo
networks:
- mqtt
logging:
driver: none
image: mvertes/alpine-mongo
volumes:
- db-data:/data/db
ports:
- "27017:27017"
volumes:
db-data:
name: db-data
networks:
mqtt:When using persistences with docker-compose file remember that the database url will be the name of the service in docker-compose, in the mongo example it will be: mongodb://mongo/dbName.
Authorization
Aedes supports user authentication through the use of a specific json file. In order to create one run the following command.
// add a user
$ aedes adduser <user> <pass> --credentials ./credentials.json
// add a user specifying the authorized topics
$ aedes adduser myuser mypass --credentials ./credentials.json \
--authorize-publish 'hello/*' --authorize-subscribe 'hello/*'
// remove a user
$ aedes rmuser myuser --credentials ./credentials.json
// start aedes with a specific set of credentials:
$ aedes --credentials ./credentials.jsonThe patterns are checked and validated using Minimatch.
The credentials file is automatically reloaded by aedes when it receives a SIGHUP.
Persistence and Emitters
The MQTT specification requires a persistent storage for offline QoS 1 subscription that has been done by an unclean client. Aedes offers several persitance options.
Supported persistences are:
- aedes-persistence: In-memory implementation of an Aedes persistence
- aedes-persistence-mongodb: MongoDB persistence for Aedes
- aedes-persistence-redis: Redis persistence for Aedes
Emitters are needed to deliver messages to subscribed clients. In a cluster environment it is used also to share messages between brokers instances
All of them can be configured from the configuration file, under the persistence and mq key.
Supported mqemitters are:
- mqemitter: An opinionated memory Message Queue with an emitter-style API
- mqemitter-redis: Redis-powered mqemitter
- mqemitter-mongodb: Mongodb based mqemitter
