sillelien/scheduler repository overview

⁠Scheduler

Scheduler is very much a work in progress. It's aim is to provide work scheduling for distributed Docker based systems.

If you use this project please consider giving us a star on GitHub⁠. Also if you can spare 30 secs of your time please let us know your priorities here https://sillelien.wufoo.com/forms/zv51vc704q9ary/⁠ - thanks, that really helps!

Please contact us through chat or through GitHub Issues.

Please use a tagged version:

FROM sillelien/scheduler:0.1.70

⁠Setting Up

Sillelien Scheduler, uses Sillelien Configurator⁠ to configure schedules. Configurator is simply a combination of a git repository and an editor to allow you to alter config in Docker images in a sensible and permanent manner.

Below is a typical docker-compose file

worker:
  image: sillelien/jessie
  command: "sleep 1000000"


scheduler:
  image: sillelien/scheduler:0.1.70
  links:
    - test:test
    - scserver:scserver

scserver:
  image: sillelien/sc-server:0.0.56
  volumes:
    - /var/sc/config/server:/repo
  ports:
    - "1500"
    - "9418"

sceditor:
  image: sillelien/sc-editor:0.0.56
  volumes:
    - /var/sc/config/editor:/config
  links:
    - scserver:scserver
  ports:
    - "8080:8080"

Here you can see the three parts: the Configurator server, the Configurator editor and the Scheduler. The editor allows you to create and modify Scheduler YAML files, the server stores them in a git repository and Scheduler uses them to Schedule work.

When you first start up this docker-compose arrangement Scheduler will create the appropriate directories and files for you to use.

⁠Creating a Job

Scheduler schedules Jobs, these jobs are read from a YAML file. An example schedule is:

date_job:
  cron: "* * * * *"
  action: 
    type: tutum_exec
    service: "test"
    command: "date"

Currently the supported action types are tutum_exec only.

⁠tutum_exec

The action should contain type: tutum_exec, the service field is the name of the Tutum service to use and the command is the command string to be executed on that service.
