Musl 1.2.4 adds TCP DNS fallback
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]).

Ask HN: Have You Left Kubernetes?
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: Cache Container Images in Kubernetes
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.

Can Kubernetes pre-pull and cache images?
I found recently this tool kube-fledged that should do what you want..

Best way to mirror images to improve their availability for a cluster?
I recommend you also look at kube-fledged this is more appealing IMHO.

shell-operator & addon-operator v1.0.0-rc1 to simplify creating Kubernetes operators & extend your K8s
addon-operator has no built-in magic around Helm, it basically runs "helm upgrade --install --values GENERATED_VALUES.yaml" to install a chart for the module. I guess that you can use beforeAll or beforeHelm hooks to transform files in the templates folder with whatever tool you have in the image. Although it's not an immutable way, still it is possible.
What are some alternatives?
kraken - P2P Docker registry capable of distributing TBs of data in seconds
cloud-on-k8s - Elastic Cloud on Kubernetes
ImageWolf - Fast Distribution of Docker Images on Clusters
kubeip - Assign static public IPs to Kubernetes nodes (GKE, EKS)

db-operator - The DB Operator creates databases and make them available in the cluster via Custom Resource.
containers-roadmap - This is the public roadmap for AWS container services (ECS, ECR, Fargate, and EKS).
