    View Code Deploy this example with Pulumi

    A video thumbnail extractor using serverless functions. The video processing function is packaged as a Docker container.

    Navigate to Running Container Images in AWS Lambda for a full walkthrough.


    To run this example, make sure Docker is installed and running.

    Running the App

    1. Create a new stack:

      pulumi stack init dev
    2. Configure Pulumi to use an AWS region of your choice, for example:

      pulumi config set aws:region us-west-2
    3. Restore NPM modules via npm install or yarn install.

    4. Preview and deploy the app via pulumi up. The preview will take some time, as it builds a Docker container. A total of 16 resources are created.

      $ pulumi up

    8. Download the key frame:

      $ aws s3 cp s3://$(pulumi stack output bucketName)/cat.jpg .
      download: s3://***/cat.jpg to ./cat.jpg

    Clean up

    To clean up the resources, you will first need to clear the contents of the bucket.

    aws s3 rm s3://$(pulumi stack output bucketName) --recursive

    Then, run pulumi destroy and answer the confirmation question at the prompt.
