Pull down just this directory to follow along: ```bash git clone --filter=blob:none --sparse https://github.com/pulumi/examples pulumi-examples git -C pulumi-examples sparse-checkout set aws-ts-lambda-thumbnailer cd pulumi-examples/aws-ts-lambda-thumbnailer ``` 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](https://www.pulumi.com/blog/aws-lambda-container-support/) for a full walkthrough. ## Prerequisites To run this example, make sure [Docker](https://docs.docker.com/engine/installation/) is installed and running. ## Running the App 1. Create a new stack: ``` pulumi stack init dev ``` 1. Configure Pulumi to use an AWS region of your choice, for example: ``` pulumi config set aws:region us-west-2 ``` 1. Restore NPM modules via `npm install` or `yarn install`. 1. 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 Previewing update (dev) ...

View the stack outputs: ``` $ pulumi stack output Current stack outputs (1): OUTPUT VALUE bucketName bucket-7c6b55a ``` 1. Upload a video, embedding the timestamp in the filename: ``` $ aws s3 cp ./sample/cat.mp4 s3://$(pulumi stack output bucketName)/cat_00-01.mp4 upload: sample/cat.mp4 to s3://***/cat_00-01.mp4 ``` 1.
