Simple golang wrapper over github.com/robfig/cron and os/exec as a cron replacement. Additionally the application opens a HTTP port that can be used as a healthcheck.

usage

go-cron -s "* * * * * *" -p 8080 -- /bin/bash -c "echo 1"

Check the healthcheck:

$ curl -v localhost:18080
* Rebuilt URL to: localhost:18080/
* Hostname was NOT found in DNS cache
*   Trying ::1...
* Connected to localhost (::1) port 18080 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.37.1
> Host: localhost:18080
