This tool accepts Alertmanager webhook notification HTTP POST requests and forwards them to Keybase. It also offers a Watchdog feature where if notifications are not received at a regular interval, an alert will be fired to Keybase.

This project vendors its dependencies and they are maintained using Go modules.

$ go build -mod=vendor .

$ ./kbam -recipient <keybase recipient>

Additional options are available to tweak behaviour:

$ ./kbam --help
Usage of ./kbam:
  -expiry duration
        The amount of time after which a non-pinging watchdog check will be considered to have expired (default 2m0s)
  -interval duration
        The interval at which to check for watchdog expiry (default 10s)
  -keybase string
        the location of the Keybase app (default "keybase")
  -port int
        Port to listen for webhooks (default 3000)
  -template string
        Go text template definition file (default "default.tmpl")
  -recipient string
        Keybase recipient to send message to:
        1) 'team#channel' - to teams
        2) 'username' - directly to a user

In a similar way to Alertmanager itself, keybase-alertmanager offers customisable templating via Go's built-in text templating. See default.tmpl for defaults. Note that the Go template file must define templates named: keybaseAlert, watchdogAlertFire and watchdogAlertRecover.

A custom template file can be used by specifying the -template <file path> command line option.
