Informations about the package bernard-bundle
BernardBundle
Integrates Bernard neatly with a Symfony application.
Getting Started
Everything starts by installing the bundle. This is done through composer by adding the following lines
to your composer.json
file and running composer update bernard/bernard-bundle
.
Next up is adding the bundle to your kernel and configuring it in config.yml
.
Great! You are now ready to use this diddy. Go and read the rest of the documentation on Bernard at bernardphp.com.
Running the Consumer
What good is a message queue if you don't know how to run the consumer? Luckily this bundle auto registers the commands
with your application. So if you run php app/console
you should see bernard:consume
and bernard:produce
. These
work just as the documentation describes but if you are in doubt just add --help
when running the command.
It is important to use --no-debug
when running the consumer for longer periods of time. This is because Symfony by
default in debug mode collects a lot of information and logging and if this is omitted you will run into memory problems
sooner or later.
Adding Receivers
In order to know what messages needs to go where you have to register some receivers. This is done with a tag in your service definitions.
As the example shows it is possible to register the same receiver for many different message types.
Configuring Middlewares
By default the three core middlewares are registered for the consumer and only needs to be turned on. This example shows enabling all of them. But remember theese are only enabled for the consumer.
This is all good, but what if you can code your own? Luckily this is taken care of with a tag for the container through
a compiler pass. When you define your service just tag your middleware factory service with bernard.middleware
and give
it a type
attribute with either consumer
or producer
.
As the example shows a middleware factory can be registered for both the consumer and producer.
Configuration Options
There are different options that can be set that changes the behaviour for various drivers.
Doctrine
When using the doctrine driver it can be useful to use a seperate connection when using Bernard. In order to
change it use the connection
option. This also needs to be set if you default connection is called anything else
than default
.
FlatFile
The file driver needs to know what directory it should use for storing messages and its queue metadata.
The above example will dump your messages in the cache folder. In most cases you will want to change this to something because the cache folder is deleted every time the cache is cleared (obviously).
PhpRedis
PhpRedis depends on a service called snc_redis.bernard
with a configured Redis
instance. If you want to use a
different name use the phpredis_service
option:
If you're using the SncRedisBundle you have to set logging to false for the
bernhard client to ensure that is is a Redis
instance and not wrapped.
IronMQ
When using the IronMQ driver you have to configure an IronMQ
connection instance. You can configure it like the following:
Amazon SQS
To use Amazon SQS, configure your driver like this:
