It looks like a good candidate for https://github.com/plutov/awesome-functions
Isn't it possible to subscribe to push notification without the need of polling S3 for updates?
What is in the SNS message?
Both functions. Perhaps kappa?
LOL.
Document this
Read the payload of the SNS message and put that into a DynamoDB table
This could be a shell script of AWS CLI commands
The kappa commands in the README are not up to date.
That's all.
The file written by Lambda, and read by the website
How do we setup DynamoDB Stream aspect of this?
We have a little config issue - it needs to be stored somewhere so it can be ready by
Config are things like
Ideas?
Hi, Thanks for your good demo codes. When I do ./resource.py cf
, there is as following error.
ERROR
Resource Subscription required in type AWS::SNS::Topic
Resource Subscription required in type AWS::SNS::Topic`
I am following your instructions, but when I get to the point of running resources.py, the "cf" bit seems to work, but the next step fails because the resources.py script is looking for a --profile argument and you instructions say nothing about that:
./resources.py launch --region=us-west-2
Usage:
resources.py cf
resources.py launch --region= --profile=
resources.py update --region= --profile=
resources.py delete --region= --profile=
resources.py output --region= --profile=
To delete all resources created as part of getting this up and running.
It might also be worth having a reset
script that clear any state and gets the system back to the initial one without any data. I'm sure we will use this as part of testing.
Take the last 20(?) messages from DynamoDB and put them into an S3 object to be read by the website
