Overpush

Project

A self-hosted, drop-in replacement for Pushover, that uses XMPP as delivery method and offers the same API for submitting messages, so that existing setups (e.g. Grafana) can continue working and only require changing the API URL.

Build

$ go build

Configure

Overpush will try to read the overpush.toml file from one of the following paths:

• /etc/overpush.toml
• $XDG_CONFIG_HOME/overpush.toml
• $HOME/.config/overpush.toml
• $HOME/overpush.toml
• $PWD/overpush.toml

Every configuration key available in the example overpush.toml can be exported as environment variable, by separating scopes using _ and prepend OVERPUSH to it.

Run

All that’s needed is a configuration and Overpush can be launched:

$ overpush

Supervisor

To run Overpush via supervisord, create a config like this inside /etc/supervisord.conf or /etc/supervisor/conf.d/overpush.conf:

[program:overpush]
command=/path/to/binary/of/overpush
process_name=%(program_name)s
numprocs=1
directory=/home/overpush
autostart=true
autorestart=unexpected
startsecs=10
startretries=3
exitcodes=0
stopsignal=TERM
stopwaitsecs=10
user=overpush
redirect_stderr=false
stdout_logfile=/var/log/overpush.out.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
stdout_capture_maxbytes=1MB
stdout_events_enabled=false
stderr_logfile=/var/log/overpush.err.log
stderr_logfile_maxbytes=1MB
stderr_logfile_backups=10
stderr_capture_maxbytes=1MB
stderr_events_enabled=false

Note: It is advisable to run Overpush under its own, dedicated daemon user (overpush in this example), so make sure to either adjust directory as well as user or create a user called overpush.

OpenBSD rc

As before, create a configuration file under /etc/overpush.toml.

Then copy the example rc.d script to /etc/rc.d/overpush and copy the binary to e.g. /usr/local/bin/overpush. Last but not least, update the /etc/rc.conf.local file to contain the following line:

overpush_user="_overpush"

It is advisable to run overpush as a dedicated user, hence create the _overpush daemon account or adjust the line above according to your setup.

You can now run Overpush by enabling and starting the service:

rcctl enable overpush
rcctl start overpush

Use

The official Pushover API documentation shows how to submit a message to the /1/messages.json endpoint. Replacing Pushover with Overpush requires your tooling to be able to change the endpoint URL you your own server’s.

Please find an example script here that you can use as a command-line API client for both, Pushover and Overpush, to submit notifications. As Overpush does not yet have 100% feature parity, not all features might be available.
