An XMPP server written in Go.
jackal is a free, open-source, high performance XMPP server which aims to be known for its stability, simple configuration and low resource consumption.
jackal supports the following features:
- Customizable
- Enforced SSL/TLS
- Stream compression (zlib)
- Database connectivity for storing offline messages and user settings (PostgreSQL 9.5+)
- Clustering capabilities (etcd 3.4+)
- Expose prometheus metrics
- Cross-platform (OS X, Linux)
To start using jackal, install Go 1.17+ and run the following commands:
$ go get -d github.com/ortuman/jackal
$ cd $GOPATH/src/github.com/ortuman/jackal
$ make install installctl
This will fetch the code and install jackal
and jackalctl
binaries into your $GOPATH/bin
path.
By default the application will try to locate service configuration at config.yaml
, but alternatively you can specify a custom configuration path either through command line.
$ jackal --config=/your-custom-path/your-config.yaml
or environment variable:
$ env JACKAL_CONFIG_FILE=/your-custom-path/your-config.yaml jackal
Create a user and a database for that user:
CREATE ROLE jackal WITH LOGIN PASSWORD 'password';
CREATE DATABASE jackal;
GRANT ALL PRIVILEGES ON DATABASE jackal TO jackal;
Download lastest version of the PostgreSQL schema from jackal Github repository.
wget https://raw.githubusercontent.com/ortuman/jackal/master/sql/postgres.up.psql
Run the postgres script file to create database schema:
psql --user jackal --password -f sql/postgres.up.psql
Configure jackal to use PostgreSQL by editing the configuration file:
storage:
type: pgsql
pgsql:
host: 127.0.0.1:5432
user: jackal
password: password
database: jackal
That's it!
Your database is now ready to connect with jackal.
After completing database setup and starting jackal
service you'll have to register a new user to be able to login. To do so, you can use
jackal command-line tool to create a new user proving name and password.
make installctl && jackalctl user add <user>:<password>
The purpose of clustering is to be able to use several servers for fault-tolerance and scalability.
Since jackal
is a distributed system, it needs a distributed data store like etcd to share its state across the entire cluster.
To properly run jackal
in clustering mode make sure to add a cluster
section configuration in each of your service nodes.
Here's an example of how this section should look like:
cluster:
etcd:
endpoints:
- http://<etcd-host1>:<etcd-port1>
- http://<etcd-host2>:<etcd-port2>
...
port: your-cluster-node-port # default is 14369
Note the defined port
value will be used to perform cluster node communication, so make sure is reachable within your internal network.
The purpose of the extensibility framework is to provide an interface between jackal server and third-party external modules, thus offering the possibility of extending the functionality of the service for particular use cases. Extensibility gRPC API proto files can be found at jackal proto definitions repository.
The Docker deployment framework supports easy installation and configuration of jackal server.
You need to have Docker installed on your system before you can use a jackal Docker image. See Install Docker for instructions.
Download the jackal Docker image from the official Docker Hub library with this command:
docker pull ortuman/jackal:latest
Start a new jackal Docker container with custom configuration.
docker run --name=jackal \
--mount type=bind,src=/path-on-host-machine/my-custom-config.yaml,dst=/jackal/config.yaml \
-d ortuman/jackal:latest
Alternatively, and with the purpose of facilitating service mounting, you can make use of docker-compose
as follows:
docker-compose -f dockerfiles/docker-compose.yml up
This command will spin up a jackal
server along with its dependencies on a docker network and start listening for incoming connections on port 5222
.
Once up and running, don't forget to register one or more users using jackalctl
.
