kube-fledged VS terraform-cdk

Exactly. Part of the appeal to consolidate all of our container images to use Debian-slim is the ability to optimise the caching of layers, both in our container registry but also on our kubernetes cluster’s nodes (which can be done in a consistent manner with kube-fledged[1]).

If you're pulling big images you could try kube-fledged (it's the simplest option, a CRD that works like a pre-puller for your images), or if you have a big cluster you can try a p2p distributor, like kraken or dragonfly2.

Also there's that project called Nydus that allows starting up big containers way faster. IIRC, starts the container before pulling the whole image, and begins to pull data as needed from the registry.

kube fledged - pre pull containes in nodes: https://github.com/senthilrch/kube-fledged

kube-fledged is a kubernetes add-on or operator for creating and managing a cache of container images directly on the worker nodes of a kubernetes cluster. It allows a user to define a list of images and onto which worker nodes those images should be cached (i.e. pulled). As a result, application pods start almost instantly, since the images need not be pulled from the registry. kube-fledged provides CRUD APIs to manage the lifecycle of the image cache, and supports several configurable parameters in order to customize the functioning as per one’s needs.

I found recently this tool kube-fledged that should do what you want..

I recommend you also look at kube-fledged this is more appealing IMHO.

At first I tested it to deploy an OVHcloud Managed Kubernetes Service (MKS) with a Node Pool. And step by step, it worked. I even created a Pull Request (PR) in the terraform-cdk repository to add it as an example ☺️.

I'll be trying more sample app deployments with CDK and maybe even explore CDK for Terraform.

You can use CDK with other providers using https://github.com/hashicorp/terraform-cdk

In my experience, CDK is far better than Pulumi, especially if you're mostly going to be using AWS.

I, personally, prefer Crossplane Composite Functions on top of CDK8S, but had dropped CDKTF due to bloat. You can actually manage Kubernetes updates/upgrade lifecycle with Crossplane, as well.

I was going to recommend Pulumi, but looks like CDK for Terraform is still being kept up to date.

Avoid Pulumi, get directly to source and use https://github.com/hashicorp/terraform-cdk
