Introduction

This tutorial is intended to introduce you to serverless computing in Next.

Serverless what? Google explains. It is, like, function as a service.

What better way to introduce than to create, deploy and update a full-blown serverless application?

Pick one example from the collection of Serverless examples. OMG!

What? Oh alright. The biggest one. REST API with DynamoDB! This example lets you create, retrieve, update and delete “todos”. A common denominator of apps. :-)

clone git@github.com:serverless/examples
xamples serverless-examples
erverless-examples/aws-node-rest-api-with-dynamodb

Note that there's a directory called “todos”:

s
reate.js
elete.js
et.js
ist.js
pdate.js

Impatient?

clone git@github.com:financial-times/next-serverless-example
ext-serverless-example
 install

and skip to Deploy it. Whoooo.

FT-ify and Next-ify the example

Righto. We need to make some tweaks to get it to work in the FT.

serverless.yml

Make the following changes in the serverless.yml:

vice: serverless-rest-api-with-dynamodb
vice: ft-next-app-noob

You will need to make up a unique (and more respected) system code to replace ft-next-app-noob with. It needs to start with ft-next- and end with a name of your choosing. This will be the “prefix” name for all the resources it creates in the cloud. Now…

vider:
ame: aws
untime: nodejs4.3
amRoleStatements:
 - Effect: Allow
   Action:
     - dynamodb:DescribeTable
     - dynamodb:Query
     - dynamodb:Scan
     - dynamodb:GetItem
     - dynamodb:PutItem
     - dynamodb:UpdateItem
     - dynamodb:DeleteItem
   Resource: "arn:aws:dynamodb:us-east-1:*:*"
ole: ${env:AWS_ROLE}
eploymentBucket: ${env:AWS_DEPLOYMENT_BUCKET}

That's because we're going to have a role and a deployment bucket created for us by the cool FT tooling, details of which we will then put in .env. All that will come up shortly.

Following that:

nvironment:
 TODOS_TABLE_NAME: ft-next-app-noob_${opt:stage}_todos

To avoid hardcoding the table name in the different functions, we'll create the environment variable and use it. So, in todos/(create|delete|get|list).js files:

     TableName: 'todos',
     TableName: process.env.TODOS_TABLE_NAME,

Back in serverless.yml, update the DynamoDB table definition:

     TableName: 'todos'
     TableName: ft-next-app-noob_${opt:stage}_todos

and

   DeletionPolicy: Retain

to delete the table when we delete the application.

Finally, put this at the bottom:

kage:
xclude:
 - node_modules/serverless/**

which is not used by the application itself. In Next, every little performance tweak helps. :-)

Makefile

Create a Makefile with tasks to deploy and remove the application.

If in Next, ensure n-makefile is present in the folder:

ude n.Makefile

else:

tup environment variables
lude .env
rt $(shell [ -f .env ] && sed 's/=.*//' .env)
node_modules/.bin on the PATH
L := /bin/bash
rt PATH := ./node_modules/.bin:$(PATH)

Add the following tasks:

oy:
erverless deploy --verbose --region eu-west-1 --stage dev

:
erverless remove --verbose --region eu-west-1 --stage dev

Serverless tooling

Either:

install -g serverless

or

install --save-dev serverless

Tough decision… I figure the latter is better because we can ensure everyone has the same version.

Keys, role & deployment bucket

Progress. I've left the most uninspiring task to last!

We need to get a key with which to setup all the AWS access keys (secrets!), role and deployment bucket for our application. I have good news and bad news.

Get a key to setup access

The good news is that we are so modern that we can get the key through a Slackbot! Boom-boom. In Slack, in any channel (noone will know):

keyfor kon_policygen personal

Then check your email and through that you should see an apiKey field which is what you want.

Setup access

Now the bad news is that the Konstructor webpage with which we use to setup access for applications is more confusing than knowing whether Father Santa exists. Let's do it a better way: cURL.

Replace YOUR_API_KEY_IN_HERE with the aforementioned key and the system code name:

 -H 'x-api-key: YOUR_API_KEY_IN_HERE' -X POST -d '{
 "systemCode": "ft-next-app-noob",
 "policyDescription": "Next app by noob",
 "performTestRun": "false",
 "requireS3": {
   "artefacts": true,
   "application": true
 },
 "requireLambda": true,
 "requireApiGateway": true,
 "requireDynamo": true,
 "requireKinesis": true,
 "requireCloudformation": {
   "required": true,
   "changeRequestSetName": "Serverless-2016-10-31"
 }
ttps://awspolicy-api-d.in.ft.com/v1/create > policy.json

This policy.json will now have the all the information we need.

.env

Pick the bits we need from the policy.json and put in a new .env file:

 -e 'const p = require("./policy.json");
    console.log(`AWS_ACCESS_KEY_ID=${p.accessKey.accessKeyId}`);
    console.log(`AWS_SECRET_ACCESS_KEY=${p.accessKey.secretAccessKey}`);
    console.log(`AWS_ROLE=${p.role.arn}`);
    console.log(`AWS_DEPLOYMENT_BUCKET=${p.artefactBucket.name}`);' > .env
olicy.json

This is just brilliance. :-) The excitement can now begin!

Deploy it

Wooo.

 deploy

and you should see something like:

How fantastic! Let's cURL one of the functions:

which is the empty list.

Update or delete it all

The deployment is completely managed (“Infrastructure as Code”) and so it's just as easy to update (by running make deploy again) and to delete:

FAQs

I've forgotten what the URLs are for my application

Add a task to the Makefile:

:
@serverless info --verbose --region eu-west-1 --stage prod

and run it.

How do I get multiple applications to work together?

Ask Ben about using Exporting Stack Output Values which outputs useful information such as references for use by other applications.

How to test?

You can test locally using serverless invoke local --stage dev --function list (you may need to npm install --save aws-sdk - not forgetting to exclude this in serverless.yml because it's already available in the Lambda container).

You can test the deployed function using the same command as above but without local.

Please read also: Serverless testing

What about CircleCI and logging?

That's a Work in Progress. Contact us for the latest update. :-)

Problems?

Please contact Ben Fletcher or #ft-next-platform (if Next), or #cloud-enablement.

I highly recommend:

• Serverless framework guide - how to use the Serverless framework
• AWS Resource Property Types Reference - help with Resources section… what properties are required, what they do, etc.
• Serverless repo - where you can search for issues
• Serverless testing - some ideas regarding serverless testing (don't forget you've got dev and have a look at serverless --help regarding invoking functions locally)
