Creating API Gateway with ACK(AWS Controllers for Kubernetes)

Akhil Sai Latchireddi — Sat, 26 Nov 2022 13:41:30 +0000

To create the API Gateway with ACK we need to install the required controllers.

Terraform code to install the EKS Blueprints:
https://github.com/aws-ia/terraform-aws-eks-blueprints

terraform apply -target="module.eks_blueprints"

once the addon is installed in EKS we can use the addon to create a API Gateway in our EKS cluster using helm or kubectl apply.
https://github.com/AkhilSaiLatchireddi/eks-ack-api-gateway/blob/main/http-api-gw-v2-ack-eks.yaml

clone the repo and run:

kubectl apply -f http-api-gw-v2-ack-eks.yaml

Dynamic provisioning of Persistent Volumes using Amazon EFS CSI driver in EKS.

Akhil Sai Latchireddi — Wed, 23 Nov 2022 17:27:11 +0000

EFS CSI driver supports both static and dynamic provisioning.

dynamic provisioning creates an access point for each pv under the hood. This means you have to create an Amazon EFS file system manually and provide it as input to the storage class parameters. it will not create the EFS automatically.
