![]() This allows kube-controller-manager to allocate CIDRs to nodes (with allocate-node-cidrs=true), but will not try to configure them on the cloud provider, even if the cloud provider supports Routes. The default is configure-cloud-routes=true, and it will only try to configure routes if allocate-node-cidrs is also configured, so the default behaviour is unchanged. This is useful because on AWS the cloud provider configures routes by setting up VPC routing table entries, but there is a limit of 50 entries. So setting configure-cloud-routes on AWS would allow us to continue to allocate node CIDRs as today, but replace the VPC route-table mechanism with something not limited to 50 nodes. We can't just turn off the cloud-provider entirely because it also controls other things - node discovery, load balancer creation etc. Fix #25602 |

Kubernetes-Mesos
Kubernetes-Mesos modifies Kubernetes to act as an Apache Mesos 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, Spark, and Chronos, Cassandra, 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, 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 or DCOS UI. Both download releases from the Mesosphere Universe, 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.
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 or the kubernetes-mesos repository 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:
To get up and running with Kubernetes-Mesos, follow:
- the Getting started guide to launch a Kuberneters-Mesos cluster,
- the Kubernetes-Mesos Scheduler Guide for topics concerning the custom scheduler used in this distribution.
