Plugins and utilities for supervisor
Project description
Introduction
mr.laforge is a utility for supervisord in a development environment. It let’s you easily make sure that supervisord and specific processes controlled by it are running from within shell and Python scripts.
Usage
Installation as a script
One way to use it, is by installing it as a script. That’s also the way to use it in shell scripts. You can either just install it as an egg or you can install it in a buildout:
[mr.laforge] recipe = zc.recipe.egg eggs = mr.laforge
Either way you will get a supervisorup script. Just running it will check whether supervisord is running and if not will start it. You can also provide process names on the command line and those will be started if they are not already running.
Usage from a Python script
You can use the up method in mr.laforge which similar to the supervisorup script takes process names as arguments.
One example is a zc.recipe.testrunner part in a buildout like this:
[test] recipe = zc.recipe.testrunner eggs = ... mr.laforge initialization = import mr.laforge mr.laforge.up('solr-test')
As you can see, you have to add the egg, so it can be imported by the initialization code added to the test script created by zc.recipe.testrunner. The up call gets solr-test as an argument to make sure that the solr-test process is running for the tests.
Another example is an initialization snippet in a script created by zc.recipe.egg:
[paster] recipe = zc.recipe.egg eggs = ... mr.laforge dependent-scripts = true scripts = paster initialization = import mr.laforge mr.laforge.up('solr')
Now everytime you run the paster script created by this, it’s checked that supervisord and the solr process controlled by it are running.
