I'm trying to package/deploy my AWS SAM Lambda function written with dotnet core. I have 3 files:
pipeline.yml is a CloudFormation template creating a CodeBuild project, sets environmental variables, and wires up GitHub webhook to a specific buildspec.yml file.
buildspec.yml installs needed packages, calls dotnet lambda package which generates a zipped file containing .Net packaged app. Then calls sam package and sam deploy which is supposed to update the Lambda function with new codebase.
template.yml contains the code for Lambda function which gets packaged and deployed by sam commands.
Here's my pipeline.yml code:
AWSTemplateFormatVersion: "2010-09-09"
Parameters: [REMOVED FOR BREVITY]
Resources:
CodeBuildProject:
Type: AWS::CodeBuild::Project

Here's my buildspec.yml file:
version: 0.2
phases:

runtime-versions:
dotnet: 2.2
commands:
- export PATH="$PATH:/root/.dotnet/tools"
- dotnet tool install -g Amazon.Lambda.Tools
- pip install aws-sam-cli

commands:
- dotnet restore
build:
commands:
- cd $FOLDER
- dotnet lambda package --configuration release --framework netcoreapp2.1 -o ./$ZIPPED_APPLICATION
- sam package --template-file template.yml --s3-bucket $S3_DEPLOYMENT_BUCKET --output-template-file packaged-template.yml --region us-east-2
- sam deploy --template-file packaged-template.yml --stack-name event-publisher-app --capabilities CAPABILITY_IAM --region us-east-2
Here's my template.yml file:
AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
EventPublisherLambda:

I'm getting this error in CodeBuild output:
[Container] 2019/10/01 05:15:48 Phase complete: BUILD State: FAILED
[Container] 2019/10/01 05:15:48 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: sam package --template-file template.yml --s3-bucket $S3_DEPLOYMENT_BUCKET --output-template-file packaged-template.yml --region us-east-2. Reason: exit status 1
Is there another way to install aws-sam-cli in buildspec other than through pip? My tech is dotnet core. Is there a dotnet specific way to install aws-sam-cli?
NOTE: if I replace sam package/deploy commands with aws s3 cp $ZIPPED_APPLICATION s3://$S3_DEPLOYMENT_BUCKET/$ZIPPED_APPLICATION the process works. So, it does not appear to be an issue with environmental variables.
I'm completely stumped at how to get sam package/deploy to work with dotnet core app. Any help is appreciated.
'sam package' is an alias to 'aws cloudformation package', 'sam deploy' is an alias to 'aws cloudformation deploy'. If you having trouble installing/using SAM cli, can you try using the 'aws cloudformation ...' command instead for these actions.
