fired {
raise cloudos event subscriptionRequestApproved
with eventChannel = "3f15b820-af7f-012f-4c6e-00163ebcaaaa"
and _api = "sky";
} |
Once the subscription request is approved, the CloudOS service in both the orginating and target clouds will raise the cloudos:CloudOS_subscriptionAdded event so that a ruleset can take additional actions once the subscription has been created
| Domain | cloudos |
|---|---|
| Type | CloudOS_subscriptionAdded |
| Attributes | eventChannel, backChannel, namespace, relationship, channelName |
cloudos:CloudOS_subscriptionAdded event is raised:
| Code Block | ||||
|---|---|---|---|---|
| ||||
rule process_subscriptionRequestAddedsubscriptionAdded { select when cloudos subscriptionRequestAddedsubscriptionAdded namespace re/MyFriends/ channelName re/Coworkers Bob+Ted/ relationship re/friend-friend/ ... } |
Rejection
To reject the subscription request a ruleset in the the target cloud raises the cloudos:subscriptionRequestRejected event to signal the CloudOS service that the subscription is rejected:
| Domain | cloudos |
|---|---|
| Type | subscriptionRequestRejected |
| Attributes | eventChannel |
For example, the following postlude would raise the cloudos:subscriptionRequestRejected event:
| Code Block | ||||
|---|---|---|---|---|
| ||||
fired {
raise cloudos event subscriptionRequestRejected
with eventChannel = "3f15b820-af7f-012f-4c6e-00163ebcaaaa"
and _api = "sky";
} |
cloudos:subscriptionRejected event within the target cloud (i.e. the cloud rejecting the subscription):
| Domain | cloudos |
|---|---|
| Type | subscriptionRejected |
| Attributes | eventChannel, namespace, relationship, channelName |
The following rule is selected when the cloudos:subscriptionRejected event is seen:
| Code Block | ||||
|---|---|---|---|---|
| ||||
rule receive_subscriptionRejected {
select when cloudos subscriptionRejected
namespace re/MyFriends/
channelName re/Coworkers Bob+Ted/
relationship re/friend-friend/
...
} |
In addition, the CloudOS service raises the cloudos:subscriptionRejected event in the originating cloud:
| Domain | cloudos |
|---|---|
| Type | subscriptionRejected |
| Attributes | backChannel, namespace, relationship, channelName |
The only difference is that the attribute backChannel is contains the value of the ECI to the target cloud.
The following rule is selected when the cloudos:subscriptionRejected event is raised:
| Code Block | ||||
|---|---|---|---|---|
| ||||
rule receive_subscriptionRejected {
select when cloudos subscriptionRejected
namespace re/MyFriends/
channelName re/Coworkers Bob+Ted/
relationship re/friend-friend/
...
} |
...
| Code Block | ||||
|---|---|---|---|---|
| ||||
fired {
raise cloudos event unsubscribe
with eventChannel = "3f15b820-7aff-012f-4c6e-00163ebcfddfd"
and _api = "sky";
} |
The CloudOS service in both the originating and target clouds raises the cloudos:CloudOS_subscriptionRemoved event so that rulesets within the respective clouds can take any appropriate action:
| Domain | cloudos |
|---|---|
| Type | CloudOS_subscriptionRemoved |
| Attributes | eventChannel, backChannel, namespace, relationship, channelName |
The following rule is selected when the cloudos:CloudOS_subscriptionRemoved event is raised:
| Code Block | ||||
|---|---|---|---|---|
| ||||
rule receive_CloudOS_subscriptionRemoved { select when cloudos CloudOS_subscriptionRemoved namespace re/MyFriends/ channelName re/Coworkers Bob+Ted/ relationship re/friend-friend/ ... } |
