capsule VS vcluster

Compare capsule vs vcluster and see what are their differences.


vcluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular namespaces. (by loft-sh)

  • Happy Birthday vcluster!

    Those are just a few of what I consider important changes in the project but there have been a lot more. One thing that many of the changes have in common is that they were inspired by user requests and feedback. We appreciate the community of vcluster users and your ideas. If you have suggestions, you can open a GitHub issue or join us in the #vlcuster channel of our community Slack.

    We recently passed the one-year mark since vcluster was open sourced. If you’re not familiar with vcluster, it’s a tool for creating and managing virtual Kubernetes Clusters. A virtual cluster runs inside a namespace on a shared host cluster, but appears to the user as if it’s their own dedicated cluster.

    vcluster is an open source project that allows users to create and run virtual Kubernetes clusters inside of a shared cluster. A virtual cluster runs inside a namespace of the shared host cluster, but it appears to the user as a standalone, dedicated cluster. The Loft Labs team released the initial version of vcluster almost one year ago. Since then, a lot of momentum has built around the project, and we’ve received a lot of helpful feedback from users.

    Want to build your own plugin? Here’s a tutorial that will walk you through the process. If you have questions about vcluster plugins or using the SDK, you can open a GitHub issue on the GitHub repo or visit our community Slack to chat with the maintainers and other community members. We’d love to hear your feedback.

    Kubernetes controller (it's like an extension for Kubernetes) - . Most of the Kubernetes ecosystem is written in Go, so you have all the API definitions, libraries, etc. that you can just import, and as a result people rarely go with other programming languages. Most used libs would be kubernetes/client-go, kubernetes-sigs/controller-runtime, spf13/cobra

    Approach C This approach provides a way to implement hard isolation among Kubernetes tenants who have no trust between them. This provides segregated master plane components for each tenant by creating a mini virtual cluster on the super Kubernetes cluster. Admins can also create custom resources in those virtual clusters as well. This is provided by projects like VirtualCluster and vCluster.
