# PMTiles on Lambda
|
|
|
|
Generates a Lambda function for deploying PMTiles on Lambda behind Lambda Function URLs or API Gateway. (CloudFront is recommended as a cache in front.)
|
|
|
|
## How To Use
|
|
|
|
```sh
|
|
git clone https://github.com/protomaps/PMTiles
|
|
cd serverless/aws
|
|
python create_lambda_function.py
|
|
```
|
|
|
|
Upload the resulting `lambda_function.zip` using the Lambda console.
|
|
|
|
Configure these Lambda environment variables:
|
|
|
|
* `BUCKET`: the S3 bucket name.
|
|
* `PMTILES_PATH`: optional, define how a tileset name is translated into an S3 key. Default `{name}.pmtiles`
|
|
* Example path setting for objects in a directory: `my_folder/{name}/file.pmtiles`
|
|
* `TILE_PATH`: optional, define the URL route of the tiles API. Default `/{name}/{z}/{x}/{y}.pbf`
|
|
|
|
## Test Event
|
|
|
|
API Gateway V2 / Lambda Function URLs:
|
|
|
|
```json
|
|
{
|
|
"rawPath": "/my-tileset-name/0/0/0.pbf"
|
|
}
|
|
```
|
|
|
|
|
|
### Monitoring
|
|
|
|
|
|
|
|
### Lambda@Edge
|
|
|
|
Lambda@Edge's multi-region features have little benefit when fetching data from S3 in a single region, and Lambda@Edge [doesn't support](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/edge-functions-restrictions.html) environment variables or responses over 1 MB. For globally distributed caching, use CloudFront in combination with Lambda Function URLs.
