Configuration¶

Pikacon uses Pythons ConfigParser to get config for connection, exchanges and queues.

Broker¶

Broker is configured as in above example. Section name is broker and options are regular pika parameters for broker. If you want to configure ssl_options create new section for those and refer that section name in broker options. Eg.:

[broker]
...
ssl = True
ssl_options = my_ssl_options

[my_ssl_options]
...

Exchange¶

Section name for exchange consists of two parts divided by ‘:’. First part is ‘exchange’ and second part is the name of the exchange. Eg.:

[exchange:myexchange]
...

The actual options below exchange section are normal key = value parameters which are used in pika.

Binding¶

The name of the binding section consists three parts divided by ‘:’. First part is always ‘binding’. Second part is the name of the queue we’re binding. Third part is name of the exchange where we’re binding the queue. Eg.:

[binding:myqueue:myexchange]

The actual options below binding section are normal key = value parameters which are used in pika.

Processing order¶

Pikacon’s processing order is following:

Connection
Channel
Exchanges
Queues
Bindings

Complete configuration example¶

[broker]
host = localhost
port = 5672
username = guest
password = guest
virtual_host = /
heartbeat = 60

[exchange:exchangename]
type = direct
durable = False
auto_delete = True

[queue:testqueue1]
durable = True
exclusive = False

[queue:testqueue2]
durable = False
exclusive = False

[queue:testqueue3]
durable = True
exclusive = False
arguments = queue:testqueue3:arguments

[queue:testqueue4]
durable = True
exclusive = False

[queue:testqueue3:arguments]
x-message-ttl = 1800000
x-dead-letter-exchange = exchangename
x-dead-letter-routing-key = key4

[binding:testqueue1:exchangename]
routing_key = key1

[binding:testqueue2:exchangename]
routing_key = key2

[binding:testqueue3:exchangename]
routing_key = key3

[binding:testqueue4:exchangename]
routing_key = key4

Above example configures connection to broker at localhost. It defines one direct exchange called exchangename and four queues called testqueue1, testqueue2, testqueue3 and testqueue4. Testqueue3 has extra arguments which define dead letter exchange. All queues are bound to our only exchange with routingkeys key1, key2, key3 and key4.
