This sample shows you how to blur an image using ImageMagick in a Storage-triggered Cloud Function.

View the source code.

1. Follow the Cloud Functions quickstart guide to setup Cloud Functions for your project.

2. Clone this repository:

    git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git
    cd nodejs-docs-samples/functions/imagemagick
   

3. Create a Cloud Storage bucket for storing images (if you already have one you want to use, you can skip this step):

    gsutil mb gs://YOUR_BUCKET_NAME
   

   • Replace YOUR_BUCKET_NAME with the name of your image Bucket.

4. Create a Cloud Storage Bucket to stage our deployment:

    gsutil mb gs://YOUR_STAGE_BUCKET_NAME
   

   • Replace YOUR_STAGE_BUCKET_NAME with the name of your Cloud Storage Bucket.

5. Deploy the blurOffensiveImages function with a Storage trigger:

    gcloud alpha functions deploy blurOffensiveImages --trigger-bucket=YOUR_BUCKET_NAME --stage-bucket=YOUR_STAGE_BUCKET_NAME
   

   • Replace YOUR_BUCKET_NAME with the name of your image Cloud Storage Bucket.
   • Replace YOUR_STAGE_BUCKET_NAME with the name of your Cloud Storage Bucket.

6. Upload an offensive image to your image Storage bucket, such as this image of a flesh-eating zombie: https://cdn.pixabay.com/photo/2015/09/21/14/24/zombie-949916_1280.jpg

7. Check the logs for the blurOffensiveImages function:

   gcloud beta functions get-logs blurOffensiveImages
   

   You should see something like this in your console:

   D      ... User function triggered, starting execution
   I      ... `The image zombie.jpg has been detected as inappropriate.`
   D      ... Execution took 1 ms, user function completed successfully
