registry.k8s.io VS containers-roadmap

If you stop to think about, what AWS is selling here, it's quite funny. Most of the infrastructure behind registry.k8s.io is hosted on AWS (and also GCP). So AWS essentially tells you: Don't trust the upstream registry, it might go down, cache it on your own registry, hosted also by us.

For example: if you only allow cluster autoscaler and metrics server from registry.k8s.io you can pull those images through the cache as someone who has create repo IAM privileges. If someone without create repo privileges tries to pull a new image it will fail because they can't create the initial repo.

https://registry.k8s.io (the root url at /) redirects you to https://github.com/kubernetes/registry.k8s.io where we have an issue tracker.

❗ This container is having trouble accessing https://registry.k8s.io

Hosting a forwarding / redirect server instead of actually hosting images is probably a decent idea.

The K8s proxy is redirecting from only hosting on GCR to community-owned registries - https://kubernetes.io/blog/2023/03/10/image-registry-redirec...

You can view the code here - https://github.com/kubernetes/registry.k8s.io

But because everyone is already pointing at gcr.io (just like many openfaas users point at docker.io/) - they're having to do a huge campaign to announce the new URL - the same would apply with the author's solution here.

I wrote some automation for hosting (not redirects) in arkade with the OSS registry - Get a TLS-enabled Docker registry in 5 minutes - https://blog.alexellis.io/get-a-tls-enabled-docker-registry-...

The registry is also something you can run on a VM if you so wish, and have act as a pull through cache.

Apart from reliability - GitHub's container registry is the current next best option - but we have to ask ourselves, what happens when they start charging or the outages start to last longer or are more frequent than 1-2 times per week as we've seen in Q1 2023.

One annoyance with how docker images are specified is they include the location where they are stored. So if you want to change where you store you image you break everyone.

I wonder if what regsitry.k8s.io does could be generalized:

https://github.com/kubernetes/registry.k8s.io/blob/main/cmd/...

The idea is the depending on which cloud you are pulling the image from, they will use the closest blob store to service the request. This also has the effect that you could change the source of truth for the registry without breaking all Dockerfiles.

If you are using updated helm charts then most of them have already replaced with registry.k8s.io, for example nginx ingress so not really breaking change.

Thanks for showing up and answering questions. Congratulations on the release.

What kind of plans for support of Rust's evolving async ecosystem?

Any particular reason why the public roadmap does not show the columns similar to "Researching", "We're Working On It" like the other similar public AWS Roadmaps? See example for Containers: https://github.com/aws/containers-roadmap/projects/1

Would be nice to have fully working examples on Github, for most common scenarios across most AWS services. This is something that historically

Second, We will only rely on one managed node group, but we will leverage Karpenter; however, karpenter needs to be deployed on a node. (This may change soon once the Karpenter is available on the EKS Control Plane.) [EKS] Karpenter inside control plane · Issue #1792 · aws/containers-roadmap

As written in the AWS documentation, during periods of extremely high demand, Fargate Spot capacity might be unavailable. In concrete terms, if your ECS service is set up to execute tasks in 100% Spot, there is a risk of running out of capacity. A workaround has been created in the hope that one day this issue will be implemented by the AWS team. This workaround allows you to set up two ECS services :

Deploying Fargate with CDK has to have been the most pleasant developer experience I have ever had with any product so far.

If image caching becomes a reality with Fargate I can't imagine a need to ever use anything else

Eks Fargate doesn't support spot yet https://github.com/aws/containers-roadmap/issues/622

Until podman could be used with AWS ECR/ECS it's pretty much moot in my case: https://github.com/aws/containers-roadmap/issues/626
