YAML格式
ROSTemplateFormatVersion: '2015-09-01'
Parameters:
AutoDeleteState:
AllowedValues:
- 'True'
- 'true'
- 'False'
- 'false'
Description: 'Specifies whether the Auto Delete attribute is configured. Valid
values:
true: The Auto Delete attribute is configured. If the last queue that is bound
to an exchange is unbound, the exchange is automatically deleted.
false: The Auto Delete attribute is not configured. If the last queue that is
bound to an exchange is unbound, the exchange is not automatically deleted.'
Type: Boolean
ExchangeName:
Description: The name of the exchange.
MaxLength: 255
Type: String
ExchangeType:
AllowedValues:
- FANOUT
- DIRECT
- TOPIC
- HEADERS
Description: 'The type of the exchange. Valid values:
FANOUT: An exchange of this type routes all the received messages to all the
queues bound to this exchange. You can use a fanout exchange to broadcast messages.
DIRECT: An exchange of this type routes a message to the queue whose binding
key is exactly the same as the routing key of the message.
TOPIC: This type is similar to the direct exchange type. An exchange of this
type routes a message to one or more queues based on the fuzzy match or multi-condition
match result between the routing key of the message and the binding keys of
the current exchange.
HEADERS: Headers Exchange uses the Headers property instead of Routing Key for
routing matching. When binding Headers Exchange and Queue, set the key-value
pair of the binding property; when sending a message to the Headers Exchange,
set the message''s Headers property key-value pair and use the message Headers
The message is routed to the bound Queue by comparing the attribute key-value
pair and the bound attribute key-value pair.'
Type: String
InstanceId:
Description: InstanceId
Type: String
Internal:
AllowedValues:
- 'True'
- 'true'
- 'False'
- 'false'
Description: 'Specifies whether an exchange is an internal exchange. Valid values:
false: The exchange is not an internal exchange.
true: The exchange is an internal exchange.'
Type: Boolean
VirtualHost:
Description: The name of the virtual host.
