Use localstack to mock aws services

What is localstack​

Localstack is a tool that allows you to mock aws services locally. It is very useful when you want to test your code locally without making real requests to aws.

Pre-requisite​

We need the following dependencies to get start with localstack.

  • aws cli v2
example
aws --version
aws configure
ls ~/.aws
  • docker

Install localstack​

Install the local stack following the localstack official doc.

Ensure docker desktop is running.

Then run localstack start -d

Well, It is doable. However, This way we will need to add additional logic just for this legacy items. Personally I think, for long term, this redundant logic would make SDK unclean and difficult to follow. So I'd try to avoid it if it resolvable from user end. And one another concern is that we would not know which chain was that users used to signup before. So I think it is better to let user to re-signup again.
