I have a problem with

addDefaultFunctionEnv

Method of app Object. I'm trying to bulk pass table names from storage stack to lambdas by using the method like so: StorageStack:

Copy code

export default class StorageStack extends sst.Stack {
   // Use public fields for reference in other stacks
   tables;

   constructor(scope, id, props) {
      super(scope, id, props);

      this.tables = {
         users: new sst.Table(this, "Users", {
            fields: {
               // fieldspecs
            },
            // more table specs
         }),
         organisations: new sst.Table(this, "Organisations", {
            fields: {
               // fieldspecs
            },
            // more table specs
         }),
         ... etc.

index.js:

Copy code

export default function main(app) {
   const storageStack = new StorageStack(app, "storage");

   // Add table names to process environment for lambda functions
   const tableNames = {};
   Object.keys(storageStack.tables).forEach((key) => {
      const name = 'TABLE_NAME_' + key.toUpperCase();
      tableNames[name] = storageStack.tables[key].tableName;
   });
   console.log(tableNames);
   app.addDefaultFunctionEnv(tableNames); // If i comment this line out, deployment works
   ... etc.

hey folks! quick question, does anyone know how i can support configurations for arbitrary stage names in

serverless.yml

? for example, if i want to deploy to a stage like

dev-pranav

, is there a way for me to structure this such that i fallback to my

dev

stage config? thanks!

Just starting to get familiar with using & composing CDK constructs inside SST stacks. Curious, does a stack like this look decently well-formed or are there areas you’d change to make it more performant, succinct, or better leverage SST?

Hello SST 👋 do we have an example of direct integration of APIGW to SQS ? I tried to look at all the construct methods on APIGW and SQS and couldn't find anything My worry is that if I use CDK constructs I would lose the local development benefits. Is that true ?

I'm trying to get a lambda layer of "sharp". Following this example: https://github.com/serverless-stack/serverless-stack/tree/master/examples/bucket-image-resize It seems to be missing the "layers/sharp" folder... what goes in there? The docs say to

Copy code

Unzip the packaged layer to this directory.

Does that mean copy whats in node_modules?

From the docs, how is this true [

[It supports] Lambda IAM permissions, so if a Lambda fails on AWS due to the lack of IAM permissions, it would fail locally as well

] if the lambda function is ran locally and only the results are passed back to the stub lambda in AWS?

Clayton

11/04/2021, 9:19 PM

I’m not sure how to interpret this top-level IAM role statement from Serverless Framework ↓ How might something like this be reproduced in SST or CDK for a service? Thanks in advance for any help.

Copy code

// serverless.yml

provider:
  name: aws
  iamRoleStatements:
    - Effect: Allow
      Action: cloudwatch:PutMetricData
      Resource: '*'

11/04/2021, 9:59 PM

…and a different question – Is there a smart way to dynamically pass or reference an ARN between separate services (SST projects) in the same AWS account?

Greg Martin

When running locally, is this to be expected?

👋 I just noticed this in the

sst.Table

construct: https://github.com/serverless-stack/serverless-stack/blob/cd3829ea4f004675aed8c5a4823ab8ca9198339c/packages/resources/src/Table.ts#L152 it's not super clear in the docs that you can't have something like this

Copy code

this.table = new sst.Table(this, "table", {
      fields: {
        pk: sst.TableFieldType.STRING,
        sk: sst.TableFieldType.NUMBER,
      },
      primaryIndex: { partitionKey: "pk", sortKey: "sk" },
      stream: true,
      dynamodbTable: {
        stream: dynamodb.StreamViewType.NEW_IMAGE
      }
    });

it indeed rejects the stream in

dynamodbTable

but I had to dig the code to figure that out, not critical, but worth pointing out 😄

Is there a way to setup an EventBridge eventPattern for something like this…

Copy code

event: {
  'detail-type': 'MediaConvert Job State Change',
  source: 'aws.mediaconvert',
  detail: {
    status: 'COMPLETE',
    userMetadata: {
      stackname: 'dev-idx-idx',
    },
  },
}

Right now i have this working…

Copy code

{
  "detail-type": [
    "MediaConvert Job State Change"
  ],
  "source": [
    "aws.mediaconvert"
  ],
  "detail": {
    "status": [
      "COMPLETE"
    ]
  }
}

but I also want to filter on that

userMetadata.stackname === 'dev-idx-idx'

I’m suddenly seeing this on every API request (locally)

Copy code

Warning: Ignoring extra certs from `/etc/pki/tls/certs/ca-bundle.crt`, load failed: error:02001002:system library:fopen:No such file or directory

anyone know what this is?

I am trying to add SST to existing Serverless monorepo. I need to run deployment using

seed.run

. I am encountered with this problem. 1. Serverless has a

api gateway

defined 2. Newly created SST has

congnito

and

react

app defined (previously manually deployed) The

react

app and

gateway

needs to know about

congnito

id after congnito gets deployed. The

react

app needs to know

gateway

url after gateway gets deployed. In other words, I want only

congnito

to be created first from SST then

gateway

from serverless then

react

app from sst. Is there a way to ensure this order in

seed.run

Won't SST delete

Auth

(Cognito) resource from AWS when

sst remove

is executed?

Serverless-Framework-familiar friends — does this top-level property in a serverless.yml doc need to be declared someway in SST or does SST’s build process already account for what it’s meant to accomplish?

Copy code

👋 I might be misunderstanding something but it seems like the event bridge

addRules

function has lost some functionality. here we prevent setting up the

targets

https://github.com/serverless-stack/serverless-stack/blob/eed6864ee360edeac18312182bcd923ae9e87410/packages/resources/src/EventBus.ts#L19 but it means we cannot set the

RuleTargetInput

this is the CF reference for it https://docs.aws.amazon.com/eventbridge/latest/APIReference/API_PutTargets.html I'm basically trying to set InputTransformer
and InputPath
, any pointers? or should I revert to CF for this?

I currently have a single stack that has a function used to basically keep track of any changes happening to my DDB tables as an audit log. This function is now pretty stable so it never changes, but when doing a

sst diff

it always has to build it first, which takes quite some time. This holds up checking any other changes. Just wondering if anyone has any other ideas other than separating the stack?

Is it possible to use

Auth

construct for Cognito User Pool Groups?

Gerald

11/06/2021, 3:22 PM

how do you run cdk synth?

Ömer Toraman

11/06/2021, 3:35 PM

Hello. I would like to receive your opinion on something. Users will have roles:

regular

manager

globalManager

And different roles will have different capabilities, e.g., globalManager can create users, but regular users cannot. I’m still not sure how I can approach this. I’m thinking to use Cognito User Pool, and attach users to IAM User Groups, and make the relevant API’s require appropriate role. How else can I achieve Role Based Access Control model do you think?

11/06/2021, 3:48 PM

Why sst automatically create a dynamo table? how can I disable it?

Gerald

11/06/2021, 5:28 PM

How to fix this?

Do not set the "env" prop while initializing "MyStack" stack. Use the "AWS_PROFILE" environment variable and "--region" CLI option instead.

I am just passing an env just like this

new MyStack(app, 'MyStack', {

env: {

account: '123456789012',

region: 'us-east-1'

},

});

I am just adding route53 record for the custom domain of my user pool

new route53.ARecord(this, "CustomerUserPoolDomainARecord", {

zone: _props_?.hostedZone!,

recordName: domainName,

target: route53.RecordTarget.fromAlias(

new route53Targets.UserPoolDomainTarget(userPoolDomain)

),

});

What does this error means?

then cd into the repo and run npm run

Copy code

npm run test

I get ✅ If I then run

Copy code

npx create-react-app frontend --use-npm

per the docs and then run

Copy code

npm run test

the tests fail. The error is similar to

I just followed the NextJS demo tutorial to the letter - the live Lambda part worked fine then deployment to prod seemed ok, but on clicking the "Click Me" I got the lovely inline error: 503 Error, The lambda function associated with the Cloudfront distrib is invalid or doesn't have the required permissions.... this isn't inspiring much confidence for a first go I gotta say!

I was thinking about building something like this

Copy code

myCoolApp
  /stacks
  /frontend - a react app 
  /website - a gatsby site

I’d then have my app deploy at

Copy code

<http://app.myCoolApp.com|app.myCoolApp.com> //react site
<http://www.myCoolApp.com|www.myCoolApp.com> //gatsby
<http://myCoolApp.com|myCoolApp.com> // gatsby

Or something. Really I just want to avoid Next but have some static content for SEO. Any ideas?

For configuring Cognito, which one should be used? 1.

Copy code

new Auth(this, "Auth", {
  cognito: { signInAliases: { email: true } },
});

Copy code

new Auth(this, "Auth", {
  cognito: {
    userPool: {
      signInAliases: { email: true, phone: true },
    },
  },
});

There are examples for both of them in the documentation. The upgrading to v0.12.0 section ( https://docs.serverless-stack.com/constructs/Auth#upgrading-to-v0120 ) suggests to use the second one, but I’m not sure what that version corresponds to.
