Open Source Mac Clustering Software

kube-state-metrics (KSM) is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects. (See examples in the Metrics section below.) It is not focused on the health of the individual Kubernetes components, but rather on the health of the various objects inside, such as deployments, nodes and pods. kube-state-metrics is about generating metrics from Kubernetes API objects without modification. This ensures that features provided by kube-state-metrics have the same grade of stability as the Kubernetes API objects themselves. In turn, this means that kube-state-metrics in certain situations may not show the exact same values as kubectl, as kubectl applies certain heuristics to display comprehensible messages. kube-state-metrics exposes raw data unmodified from the Kubernetes API, this way users have all the data they require and perform heuristics as they see fit.

Scripts to configure a Mesos cluster using Mesos and Mesosphere services. Mesos master running the Marathon and Chronos frameworks. Mesos agent with Docker containerizer. Mesos DNS for core service discovery. Marathon load balancer using HAProxy for SSL and proxying to internal applications. To try it out locally use the Vagrant configuration. To use the scripts to build a custom Mesos cluster first install the roles in your project and configure Ansible to load roles from the roles directory provided by this project. Install the chronos-sync ruby script distributed as part of Chronos. Once installed the script can be used for keeping version controlled Chronos job definitions up-to-date with a Chronos instance. Install DCOS CLI and configure for use "inside the cluster" with configured master nodes. The configuration relies on Mesos DNS to provide the Mesos master and Marathon endpoints.
