AWS Lamba Golang Runtime

Custom Golang runtime for the execution of AWS Lambdas used in LocalStack.

This is a modification of the custom runtime of lambdaci (Thank you guys!)

This custom runtime avoids using the /var folder as main place where to locate other files. It contains the source code of the docker-lambda mockserver to build the binary.

Build and test

To build run

make build

To run the test using the example handler from examples/handler, run

make test

The output should look something like:

go install ./...
go build -o /home/thomas/workspace/localstack/awslamba-go-runtime/bin/handler examples/handler/handler.go
AWS_LAMBDA_EVENT_BODY='{"name": "localstack"}' \
_HANDLER=/home/thomas/workspace/localstack/awslamba-go-runtime/bin/handler \
/home/thomas/workspace/localstack/awslamba-go-runtime/bin/aws-lambda-mock

Create cross-plattform distributions

Run

DIST_VERSION=0.3.0 make dist

To create the following file tree:

dist
├── awslamba-go-runtime-0.3.0-linux-amd64
│   ├── aws-lambda-mock
│   └── mockserver
├── awslamba-go-runtime-0.3.0-linux-amd64.tar.gz
├── awslamba-go-runtime-0.3.0-linux-arm64
│   ├── aws-lambda-mock
│   └── mockserver
└── awslamba-go-runtime-0.3.0-linux-arm64.tar.gz

The .tar.gz files can then be used for a release.

Build for debian buster (GLIBC==2.28)

The following make target will run make dist the build in a golang:1.16-buster docker image.

DIST_VERSION=0.3.0 make build-buster
