lambdafy makes it easy to deploy any docker image verbatim on AWS Lambda that serves a website.
This frees you from the constraints of available AWS Lambda runtimes.
Download the latest release binary for your OS/architecture, extract it and put it in your path.
Create an example project in mynewlambda directory and follow its Readme.md.
lambdafy create-sample-project mynewlambdalambdafy command has completely self contained help. Run each command with
-h to see the available subcommands. There are dedicated guide commands as
well.
lambdafy example-spec is a good place to start as it's well documented and
outlines the extent of capabilities of lambdafy.
Lambdafy embeds a proxy inside of your docker image when you run lambdafy make image-name (or as part of lambdafy publish command when using non-ECR image
names) and makes it the entrypoint of the image. The resulting image is hybrid:
it behaves like the original image when run outside of lambda environment and
behaves like a lambda function when run inside of lambda environment.
Inside of lambda environment, the lambdafy proxy executes the original
entrypoint and commands as a subprocess. The proxy then translates API Gateway
Proxy requests into HTTP requests and sends them to your application which must
listen on the port provided by the PORT environment variable. The proxy then
translates the HTTP response back into API Gateway Proxy response.
