#Mock AWS Mock AWS is docker-compose project template that simulates 3 common services in AWS serverless architecture: Lambda, DynamoDB, and S3. And, our use case is mainly for students to try and learn how to use node.js to build serverless services, but it can be extended for your local lambda code development or testing.

##Start Mock AWS Environment docker-compose up

4 containers will start in the following sequence s3 & dynamodb => preprocessing => lambda

Preprocessing can let you create bucket in S3 and table in DynamoBD.

##Check Result

Keep the s3 and dynamodb container running Go to http://localhost:8000/shell/ to inspect the result.

You can check created table with

+++++++++++++++++++++++++++++++++++++++++++++++++++

var params = {}; dynamodb.listTables(params, function(err, data) { if (err) console.log(JSON.stringify(err, null, 2)); else console.log(JSON.stringify(data, null, 2)); });

You can check the data in Music table

+++++++++++++++++++++++++++++++++++++++++++++++++++

var params = { TableName: "Music", KeyConditionExpression: "Artist = :artist", ExpressionAttributeValues: { ":artist": "No One You Know" } };

dynamodb.query(params, function(err, data) { if (err) console.log(JSON.stringify(err, null, 2)); else console.log(JSON.stringify(data, null, 2)); });

You can check S3 folder for the files.

##Stop Mock AWS Environment Stop the cluster

Ctrl + C

docker-compose down

##Cleanup

Delete S3 and DB folders.
