AWS-Command

Configure aws credential

aws configure

Get I am user:
aws iam get-user

Create a bucket:

aws s3 mb s3://bucketname

Get a java function:

sam init --location gh:symphoniacloud/sam-init-HelloWorldLambdaJava

sam init --location gh:symphoniacloud/sam-init-HelloWorldLambdaJava-zip

Deploy in AWS Lambda:
sam deploy --s3-bucket $CF_BUCKET --stack-name HelloWorldLambdaJava --capabilities CAPABILITY_IAM

Inovke lambda function

aws lambda invoke --invocation-type RequestResponse --function-name HelloWorldJava --payload \"world\" outputfile.txt

Invoke lambda function with invocation type

aws lambda invoke --invocation-type Event --function-name HelloWorldJava --payload \"world\" outputfile.txt

Delete the lambda:
aws cloudformation delete-stack --stack-name HelloWorldLambda

View the cloudformation of particular stack:

aws cloudformation list-stack-resources --stack-name chapter4-sam

View the format of input or output in aws services(in this case s3):

sam local generate-event s3 delete

View bucket name:

aws cloudformation describe-stack-resource --stack-name chapter-five --logical-resource-id PipelineStartBucket --query 'StackResourceDetail.PhysicalResourceId'

The underline commands, chapter-five is the stack name and PipelineStartBucket is the bucket logical name. Result will be similar like:

chapter-five-781251715253-us-west-2-start

Upload file to s3 bucket:

aws s3 cp sampledata.json s3://chapter-five-781251715253-us-west-2-start/sampledata.json

Error 2:

java.lang.reflect.InaccessibleObjectException: Unable to make field private final java.util.Map java.util.Collections$UnmodifiableMap.m accessible

This is due to incompatable version of java with maven plugin. 

Seems like an version incompatibility between the cucumber version and the Java version you are running. It would be helpful if you provided us with both versions

Error 4:

The specified log group does not exist. (Service: AWSLogs; Status :400; Error Code....)

I don't know the reason, but the variable subsitution for cloud log group in template.yaml is not working.

Manually created the log group in cloud formation.

Error 5:

Aws resources not found in cloud9.

This has been replaced by IDE AWS toolkit, so it won't be shown in the cloud 9. If you want to see it, got to perference, disable aws toolkit in AWS Resources.
