  • Exploring cgroups v2 and MemoryQoS With EKS and Bottlerocket
    7 projects | dev.to | 19 Feb 2024
    0 is not the request we've defined. And that makes sense. Memory QoS has been in alpha since Kubernetes 1.22 (August 2021) and according to the KEP data was still in alpha as of 1.27.
  • Jenkins Agents On Kubernetes

    Note: There's actually a Structured Authentication Config established via KEP-3331. It's in v1.28 as a feature flag gated option and removes the limitation of only having one OIDC provider. I may look into doing an article on it, but for now I'll deal with the issue in a manner that should work even with a bit older versions versions of Kubernetes.
  • Isint release cycle becoming a bit crazy with monthly releases and deprecations ?

    Kubernetes supports a skew policy of n+2 between API server and kubelet. This means if your CP and DP are both on 1.20, you could upgrade your control plane twice (1.20 -> 1.21 -> 1.22) before you need to upgrade your data plane. And when it comes time to upgrade your data plane you can jump from 1.20 to 1.22 to minimize update churn. In the future, this skew will be opened to n+3 https://github.com/kubernetes/enhancements/tree/master/keps/sig-architecture/3935-oldest-node-newest-control-plane
  • Kubernetes SidecarContainers feature is merged
    7 projects | news.ycombinator.com | 10 Jul 2023
    KEP: https://github.com/kubernetes/enhancements/tree/master/keps/...

    TLDR: Introduce a restartPolicy field to init containers and use it to indicate that an init container is a sidecar container. Kubelet will start init containers with restartPolicy=Always in the order with other init containers, but instead of waiting for its completion, it will wait for the container startup completion.

    So, until now, a sidecar container was just the idea of running helper containers in you Kubernetes pod that were 'helpers' for something: connection to databases or vpns, mesh networking, pulling secrets or config, debugging... But they didn't have special status, they were just regular containers in your pod.

    This sometimes posed some problems because they weren't available for the full life cycle of the pod, notably on the init process. So if your init containers needed secrets, connections, networking... that was being provided via a sidecar container, you were going to have a hard time.

    With this change, among other things, sidecars containers are going to be available for the whole life cycle of the pod.

    There are other implications, probably, but I still haven't finished reading the KEP [0]. Check it out, and there you'll find its motivation and several interesting examples.

    The KEP (Kubernetes Enhancement Proposal) is linked to in the PR [1]. From the summary:

    > Sidecar containers are a new type of containers that start among the Init containers, run through the lifecycle of the Pod and don’t block pod termination. Kubelet makes a best effort to keep them alive and running while other containers are running.

    If further interested, I may recommend checking out the KEP. I love how they document the decision making, and all these edge cases :).
