dcron 0.8.7

Distributed Cronlike Scheduler

## Distributed Cronlike Scheduler [](https://travis-ci.org/witlox/dcron)

The aim of dcron is to offer [cron](https://en.wikipedia.org/wiki/Cron) like behaviour spanning multiple machines. The system offers a web interface to manage your jobs, and reports the health of the cluster. Everything is self contained, so you only need to start the system to have a working setup. We do however recommend that you run the system behind a reverse proxy, since there is no authentication mechanism. Please check the [docs](https://dcron.readthedocs.io) regarding installation, configuration and options.

## Details

• dcron requires Python 3.7+ in order to work.

• all nodes running dcron need to have the same software installed you want dcron to run

• dcron runs tasks at-most-once (according to schedule)

## Installation

pip install dcron

## Options

• -l or –log-file: by default we only log to stdout/stderr, specify a path and a log file will be created

• -p or –storage-path: we cache our stuff directly in memory, if you wan’t your runtime configuration to be saved, specify a folder here

• -c or –communication-port: udp broadcast is used for synchronization between nodes, specify a port here (default: 12345)

• -w or –web-port: port to host the web interface (default: 8080)

• -n or –ntp-server: given that we are doing cron, we need time sync to be relatively close, if skewed, we break (default: pool.ntp.org)

• -s or –node-staleness: after x seconds of inactivity a node is marked stale and jobs are redistributed over active nodes

• -v or –verbose: more logging
