Compressing Images

When an image is uploaded or updated to bucket your-bucket-input, an event is generated to trigger the function. The function compresses the image and stores the compressed one into bucket your-bucket-output.

Uploading an Image to Generate an Event

Log in to the OBS console, go to the object page of the your-bucket-input bucket, and upload the image.jpg image, as shown in Figure 1.

Triggering the Function

After the image is uploaded to bucket your-bucket-input, OBS generates an event to trigger the image compressing function. The function compresses the image and stores the compressed one into bucket your-bucket-output. You can view running logs of the function on the Logs tab page.

Go to the Objects page of the your-bucket-output bucket and view the size of the compressed image.
