# Kubernetes-Mesos
|
|
|
|
Kubernetes-Mesos modifies Kubernetes to act as an [Apache Mesos](http://mesos.apache.org/) framework.
|
|
|
|
## Features On Mesos
|
|
|
|
Kubernetes gains the following benefits when installed on Mesos:
|
|
|
|
- **Node-Level Auto-Scaling** - Kubernetes minion nodes are created automatically, up to the size of the provisioned Mesos cluster.
|
|
- **Resource Sharing** - Co-location of Kubernetes with other popular next-generation services on the same cluster (e.g. [Hadoop](https://github.com/mesos/hadoop), [Spark](http://spark.apache.org/), and [Chronos](https://mesos.github.io/chronos/), [Cassandra](http://mesosphere.github.io/cassandra-mesos/), etc.). Resources are allocated to the frameworks based on fairness and can be claimed or passed on depending on framework load.
|
|
- **Independence from special Network Infrastructure** - Mesos can (but of course doesn't have to) run on networks which cannot assign a routable IP to every container. The Kubernetes on Mesos endpoint controller is specially modified to allow pods to communicate with services in such an environment.
|
|
|
|
## Features On DCOS
|
|
|
|
Kubernetes can also be installed on [Mesosphere DCOS](https://mesosphere.com/learn/), which runs Mesos as its core. This provides the following *additional* enterprise features:
|
|
|
|
- **High Availability** - Kubernetes components themselves run within Marathon, which manages restarting/recreating them if they fail, even on a different host if the original host might fail completely.
|
|
- **Easy Installation** - One-step installation via the [DCOS CLI](https://github.com/mesosphere/dcos-cli) or DCOS UI. Both download releases from the [Mesosphere Universe](https://github.com/mesosphere/universe), [Multiverse](https://github.com/mesosphere/multiverse), or private package repositories.
|
|
- **Easy Maintenance** - See what's going on in the cluster with the DCOS UI.
|
|
|
|
For more information about how Kubernetes-Mesos is different from Kubernetes, see [Architecture](./docs/architecture.md).
|
|
|
|
|
|
## Release Status
|
|
|
|
Kubernetes-Mesos is alpha quality, still under active development, and not yet recommended for production systems.
|
|
|
|
For more information about development progress, see the [known issues](./docs/issues.md) or the [kubernetes-mesos repository](https://github.com/mesosphere/kubernetes-mesos) where backlog issues are tracked.
|
|
|
|
## Usage
|
|
|
|
This project combines concepts and technologies from two already-complex projects: Mesos and Kubernetes. It may help to familiarize yourself with the basics of each project before reading on:
|
|
|
|
* [Mesos Documentation](http://mesos.apache.org/documentation/latest)
|
|
* [Kubernetes Documentation](../../README.md)
|
|
|
|
To get up and running with Kubernetes-Mesos, follow:
|
|
|
|
- the [Getting started guide](../../docs/getting-started-guides/mesos.md) to launch a Kuberneters-Mesos cluster,
|
|
- the [Kubernetes-Mesos Scheduler Guide](./docs/scheduler.md) for topics concerning the custom scheduler used in this distribution.
