Hi everyone, I am trying to add redis to my stack. Is there a way to get the VPC and subnets that were created and use them for redis. I looked around and cannot find a way to get vpc. Thanks

you can do this via direct imports from CDK https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.Vpc.html

Thanks @thdxr for your help. I have an existing application that needs Redis.

If you have an existing VPC you can import it with this: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_ec2.Vpc.html#static-fromwbrvpcwbrattributesscope-id-attrs

Sorry if my question is not very clear. When building my stack the SST framework is already creating the VPC

lav-checkout-com-payments-app-my-stack/Cluster/vpc

. I am trying to use the same one. Should I use

fromVpcAttributes

to get that? Thanks again

hm are you using our RDS construct?

yup we have RDS as well

Ah ok so our RDS construct will create a VPC for itself since serverless RDS requires it - most people won't ever even need to know it exists because they're using it through the Data API. What you should do is create a new VPC and pass that into the RDS construct so it'll use it instead of making its own. Then you can use this same VPC wherever else you need it. I believe you can pass vpc in under here: https://docs.serverless-stack.com/constructs/v1/RDS#cdkcluster

Ok sounds good. I'll give this a try 🙂

note another thing to be aware of is to be fully serverless you also sort of need to be VPC-less

In our case, we had to house some of our services within a VPC for a static IP address for 1 of our partners to whitelist our services. Is there a better option for this 🤔 ?

Hey @Ash Rhazaly, afaik there isn’t an alternative. I’d say keep the least number of functions in the VPC.
