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
