Cluster Manager

Cluster Manager manages the life cycle of Kubernetes clusters from different cloud providers.

Before You Begin

Cluster Manager supports provisioning, scaling up, scaling down and shutting down of Kubernetes clusters on various cloud providers. The cluster lifecycle status and cloud provider specific configuration are stored as annotations into the Kubernetes Cluster object in the Federation. Cluster Manager uses these annotations to decide which lifecycle operation to perform and how to set up the cluster. Currently AWS and Wercker Clusters are supported. Support for more providers will be added in the near future.

Cluster Manager may be used with Navarkos to help scale out deployments to various cloud providers. When Cluster Manager is used with Navarkos, Navarkos determines on which cluster to perform the operation depending on the demand and supply.

Figure:1 cluster-manager with Navarkos Architecture

The Cluster Manager supports the following operations on clusters:

1. Provisioning: Cluster Manager can create a new Kubernetes cluster on a cloud provider.
2. Scale Up: Cluster Manager can scale up nodes on a currently provisioned cluster on any supported cloud provider.
3. Scale Down: Cluster Manager can scale down nodes on a currently provisioned cluster on any supported cloud provider.
4. Shutdown: Cluster Manager can shutdown a currently provisioned cluster on any supported cloud provider.

Build

Requirements

Cluster Manager build has been currently tested with go version 1.8.x

Clone Repository

Clone the source to a local repository

export K8S_INCUBATOR_DIR="$GOPATH/src/github.com/kubernetes-incubator"
mkdir -p $K8S_INCUBATOR_DIR
cd $K8S_INCUBATOR_DIR
git clone https://github.com/oracle/cluster-manager

Build Project

Project Makefile supports the following targets

• make build-local - cleans up and build Cluster Manager binary.
• make build-image - invokes 'build-local' by building Cluster Manager docker image.
• make build-docker - cleans up and build docker image of Cluster Manager using docker multi-stage build.
• make push-image - pushes an already created Cluster Manager docker image to registry of choice. Use ${DOCKER_REGISTRY} environment variable to specify the registry.
• make build-push-image - cleans up, build and push Cluster Manager docker image to a registry of choice. Use ${DOCKER_REGISTRY} environment variable to specify the registry.

Deploy

Follow the deploy instructions to deploy Cluster Manager.
