QUESTION
aws_stepfunctions_tasks.LambdaInvoke.__init__
takes an input_path
argument, which defaults to $
- the entire task input. How can I combine that with the context object ($$
), since my Lambda needs information from both? Or do I need to use something else, like the payload
argument, to specify more than one input?
ANSWER
Answered 2021-May-13 at 00:03To pass both, the payload and context to lambda function, you will need to wrap the original input inside the another attribute for instance Payload
QUESTION
I have an array of objects which I want to pass to a Lambda function iteratively. However, I also need to have an ECS Task running for each Lambda function I start.
I found that I would need to have an AWS Step Function where I iterate through an array of JSON inputs. For each input, I would have to start an ECS Task, wait for it to be in a RUNNING state, then move to next step where I invoke a Lambda function. In my case, the ECS Task itself does not return anything. It is supposed to stay running because the Lambda function uses it.
Currently, I have it so that the ECS Task starts but it stays stuck in the starting the ECS Task step because it does not return anything. How would I be able to wait for it be in a RUNNING state before moving to the next step?
Current Step Function definition:
...ANSWER
Answered 2021-Apr-21 at 14:54ecs:runTask can be triggered in two different ways.
- arn:aws:states:::ecs:runTask.sync > runs and waits until task is completed
- arn:aws:states:::ecs:runTask.waitForTaskToken - triggers and wait until it receives a SendTaskSucess or sendTaskFailure
We need to use second method in this case,
Pass TASK_TOKEN as environment variable to ECS task and within ECS task first few lines of code, we need to send a SendTaskSucess.
Here is an example:

QUESTION
I have two Cloudformation templates
- one which creates a VPC, ALB and any other shared resources etc.
- one which creates an elastic beanstalk environment and relevant listener rules to direct traffic to this environment using the imported shared load balancer (call this template
Environment
)
The problem I'm facing is the Environment
template creates a AWS::ElasticBeanstalk::Environment
which subsequently creates a new CFN stack which contains things such as the ASG, and Target Group (or process as it is known to elastic beanstalk). These resources are not outputs of the AWS owned CFN template used to create the environment.
When setting
...ANSWER
Answered 2021-Apr-30 at 01:10I don't have access as far as I can tell to the ARN of the target group created by the elastic beanstalk environment resource
That's true. The way to overcome this is through custom resource. In fact I developed fully working, very similar resource for one of my previous answers, thus you can have a look at it and adopt to your templates. The resource returns ARN of the EB load balancer, but you could modify it to get the ARN of EB's target group instead.

QUESTION
I'm trying to create a basic lambda and an S3 bucket using the Serverless Framework. I have cut out a small code snippet from this post: Enable Lambda function to an S3 bucket using cloudformation
...ANSWER
Answered 2021-Apr-11 at 23:10Based on the comments.
The link provided in the question showcases a CloudFormation (CFN) template, not serverless framework template. Although there are similarities between the two, they are different.
The code in the question is a mixture of both CFN and serverless templates, which makes it not work in both systems.
Thus to solve the issue, you have to check and find examples for serverless framework templates, not CFN. Then you modify your current template into valid serverless template.
QUESTION
I am wondering about how to configure AWS Lambda, SNS, and SQS for processing background tasks.
There are three ways I thought.
Option 1. A function called consumer can execute workers by receiving tasks from the queue.
Option 2. Send all tasks to SNS. One worker and one SQS receive and work from SNS.
Option 3. Directly forward the task to one SQS and one lambda from the APP.
The biggest concern is whether to directly invoke Lambda in the app or use task consumer using SQS or SNS.
My idea is from Triggering multiple lambda functions from one SQS trigger
...ANSWER
Answered 2021-Apr-09 at 03:45The typical pattern is:
- Push jobs/tasks to an Amazon SQS queue
- Configure an AWS Lambda function to subscribe to the SQS queue
- Lambda will automatically execute the Lambda function for each message in the SQS queue
I guess this matches your Option 1, but with the AWS Lambda service acting as the "consumer" that triggers the individual Lambda functions.
If there are different types of inputs (eg three different tasks) that each require a different Lambda function, then create 3 separate queues each linked to its own Lambda function (your Option 3).
Inserting Amazon SNS in-between (shown in your Option 2) makes it easier to 'fork' information, such as adding another subscriber to each message in case they need to be processed in parallel. Otherwise, it is not necessary.

I am trying to create an Event Bridge rule that will run my Lambda function every 30 mins. I based my code on this answer I found here on SO Use terraform to set up a lambda function triggered by a scheduled event source
Here is my terraform code:

...ANSWER
Answered 2021-Mar-23 at 01:08From what you posted is seems that you are not adding permissions for invocations. Your code does not show creation of aws_lambda_permission with proper rules. So you should add such permissions so that EventBridge can invoke your function (example):
