## Upload Lambda layer to AWS
|
|
|
|
1. Download the layer zip from Github Releases
|
|
|
|
2. Create a S3 bucket, or use a pre-existing bucket, upload the zip, and copy the URL
|
|
|
|
3. Create a new layer or use a pre-existing layer. (If using a pre-existing layer, Create a new verion)
|
|
|
|
4. Use the S3 file to load into to AWS Lambda Layers
|
|
|
|
5. Add the layer to your serverless function
|
|
|
|
```yaml
|
|
service: sls-with-preexisting-layer
|
|
|
|
provider:
|
|
name: aws
|
|
runtime: nodejs18.x
|
|
stage: dev
|
|
region: us-east-1
|
|
timeout: 300
|
|
|
|
functions:
|
|
chromium-test:
|
|
handler: index.handler
|
|
layers:
|
|
- arn:aws:lambda:us-east-1:************:layer:chromium:*
|
|
```
|
|
|
|
# BONUS
|
|
|
|
These steps can easily be automated using the following code:
|
|
|
|
```shell
|
|
$ chromiumVersion="112.0.0"
|
|
$ bucketName="chromiumUploadBucket"
|
|
$ wget "https://github.com/Sparticuz/chromium/releases/download/v${chromiumVersion}/chromium-v${chromiumVersion}-layer.zip"
|
|
$ aws s3 cp "chromium-v${chromiumVersion}-layer.zip" "s3://${bucketName}/chromiumLayers/chromium-v${chromiumVersion}-layer.zip"
|
|
$ aws lambda publish-layer-version --layer-name chromium --description "Chromium v${chromiumVersion}" --content "S3Bucket=${bucketName},S3Key=chromiumLayers/chromium-v${chromiumVersion}-layer.zip" --compatible-runtimes nodejs --compatible-architectures x86_64
|
|
```
