Why do we need a custom lambda runtime?

  • Let's assume that we want to execute python file in a node js environment.

  • So the container image should have both python and node js runtime and the container should compatible with lambda

How to use this demo?

  • Create a Repo in Amazon ECR.
  • Then execute the below commands to push your image to ECR from your working directory.

Note: Please change [aws_region] and [aws_account as your expected

aws ecr get-login-password --region [aws_region] | docker login --username AWS --password-stdin [aws_account.dkr.ecr.[aws_region]

docker buildx build --platform linux/amd64 -t skg/lambda-python-node .

docker tag skg/lambda-python-node:latest [aws_account.dkr.ecr.[aws_region]

docker push [aws_account.dkr.ecr.[aws_region]
  • go to the Lambda console and create a lambda function using the uploaded container image.
