Informations about the package supervisor
Yeebase.Supervisor
With this Flow package you can control and monitor your supervisor daemon http://supervisord.org/api.html and all configured processes from your Flow application. You can use it to control workers that compute job queue tickets in a complex MessageQueue scenario.
Yeebase.Supervisor is an excellent addition to Flow's Flowpack.JobQueue.Common package and some MessageQueue backend like Flowpack.JobQueue.Beanstalkd:
You would like to defer jobs in a message queue and do things asynchronous within your Flow application?
An example MessageQueue stack with Flow:
- Supervisor Daemon - monitors and controls your job queue workers (they are doing the hard work) http://supervisord.org/
- Beanstalkd Message Queue- manages what jobs to give to the workers (stupid, fast) http://kr.github.io/beanstalkd/
- Flowpack.JobQueue.Common - Flow package for putting jobs/functions into an asyncronous pipeline (using a simple @Job\Defer annotation) https://github.com/Flowpack/jobqueue-common
- Flowpack.JobQueue.Beanstalkd - The job queue implementation for Beanstalkd backends https://github.com/Flowpack/jobqueue-beanstalkd
- Yeebase.Supervisor client package - monitor and control all configured supervisor processes https://github.com/yeebase/Yeebase.Supervisor
Installation & configuration
Just add "yeebase/supervisor" as dependency to your composer.json and run a "composer update" in your root folder. You will also have to install the xml-rpc php extension (would be nice to remove this dependency in some future versions).
Configure the supervisor connection in your Settings.yaml:
Command line tool
The Yeebase.Supervisor package comes with a simple Flow command controller:
1) Test the connection to supervisor and get some details
This should output something like this:
2) Show all configured processes and their details
Just type ./flow help supervisor to get an overview of all available commands or ./flow help supervisor:processes (f.e.) on how to use a specific command.
Using the SupervisorService in your own classes
The main part of the Yeebase.Supervisor package is a the supervisor client class named "SupervisorService". In Flow you can just inject this class to your custom controllers via the following php code:
If the SupervisorService has been injected you can use it in your class without initializing it manually - something like this:
