Using an OBS Trigger¶
For details about the OBS event source, see section "Supported Event Sources".
Prerequisites¶
Before creating a trigger, ensure that you have prepared the following:
You have created a function. For details, see Creating a Function from Scratch.
You have created an OBS bucket, for example, obs_cff. For details, see Creating a Bucket.
Creating an OBS Trigger¶
Log in to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
Click the function to be configured to go to the function details page.
Choose Configuration > Triggers and click Create Trigger.
Figure 1 Creating a trigger¶
Set the following parameters:
Trigger Type: Select Object Storage Service (OBS).
Bucket Name: Specify the OBS bucket to be used as an event source, for example, obs-cff.
Events: Select events that will trigger the function. In this example, select Put, Post, and Delete. When files in the obs_cff bucket are updated, uploaded, or deleted, the function is triggered.
Event Notification Name: Specify the name of the event notification to be sent by SMN when an event occurs.
Prefix: Enter a keyword for limiting notifications to those about objects whose names start with the matching characters. This limit can be used to filter the names of OBS objects.
Suffix: Enter a keyword for limiting notifications to those about objects whose names end with the matching characters. This limit can be used to filter the names of OBS objects.
Click OK.
Triggering a Function¶
On the OBS console, upload an image ZIP package to the obs-cff bucket. For details, see Uploading a File.
Note
After the ZIP package is uploaded to the obs-cff bucket, the HelloWorld function is triggered.
