SAM DynamoDB Application for Managing Orders

This is a sample application to demonstrate how to build an application on DynamoDB using the DynamoDBMapper ORM framework to map Order items in a DynamoDB table to a RESTful API for order management.

Requirements

AWS CLI already configured with at least PowerUser permission
Java SE Development Kit 8 installed
Docker installed
Maven
SAM CLI
Python 3

Setup process

Installing dependencies

We use maven to install our dependencies and package our application into a JAR file:

mvn package

Local development

Invoking function locally through local API Gateway

Start DynamoDB Local in a Docker container. docker run -p 8000:8000 amazon/dynamodb-local
Create the DynamoDB table. aws dynamodb create-table --table-name orders_table --attribute-definitions AttributeName=orderId,AttributeType=S --key-schema AttributeName=orderId,KeyType=HASH --billing-mode PAY_PER_REQUEST --endpoint-url http://localhost:8000
Start the SAM local API.

On a Mac: sam local start-api --env-vars src/test/resources/test_environment_mac.json
On Windows: sam local start-api --env-vars src/test/resources/test_environment_windows.json
On Linux: sam local start-api --env-vars src/test/resources/test_environment_linux.json

If the previous command ran successfully you should now be able to hit the following local endpoint to invoke the functions rooted at http://localhost:3000/orders

SAM CLI is used to emulate both Lambda and API Gateway locally and uses our template.yaml to understand how to bootstrap this environment (runtime, where the source code is, etc.) - The following excerpt is what the CLI will read in order to initialize an API and its routes:

...
Events:
    GetOrders:
        Type: Api # More info about API Event Source: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#api
        Properties:
            Path: /orders
            Method: get

Packaging and deployment

AWS Lambda Java runtime accepts either a zip file or a standalone JAR file - We use the latter in this example. SAM will use CodeUri property to know where to look up for both application and dependencies:

...
    GetOrdersFunction:
        Type: AWS::Serverless::Function
        Properties:
            CodeUri: target/aws-sam-java-rest-1.0.0.jar
            Handler: com.amazonaws.handler.GetOrdersHandler::handleRequest

Firstly, we need a S3 bucket where we can upload our Lambda functions packaged as ZIP before we deploy anything - If you don't have a S3 bucket to store code artifacts then this is a good time to create one:

export BUCKET_NAME=my_cool_new_bucket
aws s3 mb s3://$BUCKET_NAME

Next, run the following command to package our Lambda function to S3:

sam package \
    --template-file template.yaml \
    --output-template-file packaged.yaml \
    --s3-bucket $BUCKET_NAME

Next, the following command will create a Cloudformation Stack and deploy your SAM resources.

sam deploy \
    --template-file packaged.yaml \
    --stack-name sam-orderHandler \
    --capabilities CAPABILITY_IAM

See Serverless Application Model (SAM) HOWTO Guide for more details in how to get started.

After deployment is complete you can run the following command to retrieve the API Gateway Endpoint URL:

aws cloudformation describe-stacks \
    --stack-name sam-orderHandler \
    --query 'Stacks[].Outputs'

Testing

Running unit tests

We use JUnit for testing our code. Unit tests in this sample package mock out the DynamoDBTableMapper class for Order objects. Unit tests do not require connectivity to a DynamoDB endpoint. You can run unit tests with the following command:

mvn test

Running integration tests

Integration tests in this sample package do not mock out the DynamoDBTableMapper and use a real AmazonDynamoDB client instance. Integration tests require connectivity to a DynamoDB endpoint, and as such the POM starts DynamoDB Local from the Dockerhub repository for integration tests.

mvn verify

Running end to end tests through the SAM CLI Local endpoint

Running the following end-to-end tests requires Python 3 and the requests pip package to be installed. For these tests to succeed,

pip3 install requests
python3 src/test/resources/api_tests.py 3

The number that follows the test script name is the number of orders to create in the test. For these tests to work, you must follow the steps for local development.

Appendix

AWS CLI commands

AWS CLI commands to package, deploy and describe outputs defined within the cloudformation stack:

sam package \
    --template-file template.yaml \
    --output-template-file packaged.yaml \
    --s3-bucket REPLACE_THIS_WITH_YOUR_S3_BUCKET_NAME

sam deploy \
    --template-file packaged.yaml \
    --stack-name sam-orderHandler \
    --capabilities CAPABILITY_IAM \
    --parameter-overrides MyParameterSample=MySampleValue

aws cloudformation describe-stacks \
    --stack-name sam-orderHandler --query 'Stacks[].Outputs'

aws-sam-java-rest's Issues

transactGetItems / transactWriteItems ( ConditionCheck )

I suppose this might not be the correct place to ask for this, but since its the linked example on the page dynamodb-local page I will put it here.

It seems as if the dynamodb-local docker container does not support the ConditionCheck. At least I am getting an "unimplemented" error.

Are there any plans on supporting this?

Question: Best practice for creating the dynamo table

Hello and thanks for the sample app!

I see that in this project there is an endpoint triggered from a POST request, that attempts to create the dynamodb table. I realize this is just a sample project but I was expecting the table definition to be in the template.yaml file instead of java code and now I wonder if there was a reason for the author to do it this way instead

Dynamo unreachable

Working on Windows 10 I am unable to browse content of database with http://127.0.0.1:3000/orders endpoint due to docker-related networking issues. This is due to endpoints being defined with hostname docker.for.windows.localhost which is no longer domain name used by docker during Docker for Windows installation. Recommended is to use host.docker.internal. This change fixes the issue and provides excellent out-of-the-box experience for fresh install of docker for windows.

I tried running other containers in docker and exposing ports which work perfectly example

`docker run -d -p 80:80 nginx

`
So I don't think it something in docker that's missing here

Not working out of the box

One has to use the following command:
aws cloudformation deploy --template-file /Users/nmas409/aws-sam-java-rest/aws-sam-java-rest/packaged.yaml --stack-name sam-orderHandler --capabilities CAPABILITY_IAM
Waiting for changeset to be created..

But getting this error.

Failed to create the changeset: Waiter ChangeSetCreateComplete failed: Waiter encountered a terminal failure state Status: FAILED. Reason: [/Resources/DeleteOrderFunction/Type/Environment/Variables/TABLE_NAME] 'null' values are not allowed in templates

This doesn't work at all:
sam deploy
--template-file packaged.yaml
--stack-name sam-orderHandler
--capabilities CAPABILITY_IAM

Gradle implementation

A lot of projects have abandoned Maven out of preference to use Gradle - can we get an updated example that uses Gradle instead of Maven?

How to best send command line args to local dynamodb docker container

Sorry if this is the wrong git repo - I couldn't find where the dockerfile for amazon/dynamodb-local was being maintained.

2 questions here:

Currently, to send command line args as described here https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.UsageNotes.html it looks like I need to send the full args to the java process instead of just the args to configure the dynamodb server. So instead of running docker run -it --rm amazon/dynamodb-local -sharedDb I need to run docker run -it --rm amazon/dynamodb-local -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb
Would it be possible to change the entrypoint/cmd of the dockerfile to handle the java args for you and the user just pass in the extra arguments? I think the more common use case is to just specify the dynamodb args, but if a user wanted to modify the java args they should be able to override the entrypoint in their own docker run
What directory in the container should I mount if I want to persist the .db file?

DaggerOrderComponent is not found.

In my develop environment (Eclipse IDE), an error occurs that DaggerOrderComponent is not found. Where is the DaggerOrderComponent ? Is there in the source code?
