lambda-layer-chromedriver
Run selenium-based automation tests in a lambda function using the latest AmazonLinux2 (AL2) with Node10.
This packages uses a pre-built binary (chrome-aws-lambda) for chromium which is built for AL2018 with Node8. In order to get this working with Node10 as well as allowing chromedriver to run additional packages were built using the AmazonLinux2 docker image.
Some further optimizations are needed as this does not currently try to minimize to the fullest extent the size of the layer file. Additionally, chrome-aws-lambda bundles a stripped down version of iltorb which was built for node8, so instead we are just bundling the full version of iltorb built for node10. Some of the chromium dependencies might not be needed if/when chrome-aws-lambda is updated to support node10. See alixaxel/chrome-aws-lambda#37 to follow the github issue.
Building and publishing the lambda layer
The following assumes you have a default aws profile setup with the AWS CLI installed as well as docker.
The latest layer zip file can be found in the layers folder if you'd prefer to use the pre-built layer.
You can also use the docker image to easily extend the layer such as in the webdriver.io example
Docker images: https://cloud.docker.com/repository/docker/jensbodal/lambda-amazonlinux2/tags
Build the layer zip file
./create-lambda-layer.sh
Publish the layer
./publish-layer ${MY_BUCKET_NAME}
# publishes the lambda-layer-chromedriver-al2-node10.zip layer to your lambda layers
# the layer zip file artifact will be stored in s3 in the specified bucket
