aws-lambda-dotnet-build

Contains the tools to build & package dotnet core aws lambdas

Usage

  1. Start a container with your project mapped as a volume
docker run -it --rm -v "$(PWD):/var/app" cfbarbero/aws-lambda-dotnet-build /bin/bash
  1. Run dotnet commands against your project
    • Restore
    dotnet restore
    • Test
    dotnet test tests/tests.csproj
    • Build
    cd src/project
dotnet build
    • Lambda Package - note: this is different that the standard 'dotnet publish' command. It automatically flattens the platform specific 'runtimes' folder in the generated build folder to target the aws lambda environment. AWS Lambda runtime can't dynamically load platform assemblies from the runtime folder.
    cd src/project
dotnet lambda package -f netcoreapp1.0 -c Release -o build.zip
    • Compile SAM template - note: this assumes that you have valid credentials in the container.
    aws cloudformation package --template-file serverless.template --s3-bucket <sam-artifactbucket> --output-template-file compiledTemplate.yaml

AWS Credentials

To map credentials into the container you should map your ~/.aws folder into the container.

Running your container like below will set the aws credentials/config from your local machine available to any user of the docker container (ie root, jenkins, etc)

docker run -it --rm -e "HOME=/home" -v $HOME/.aws:/home/.aws cfbarbero/aws-lambda-dotnet-build
