Data Aware Scheduler (PoC)

This Scheduler works (and is tested) with Kubernetes 1.5

Dependency Managment

For the dependency managment was (dep)[https://github.com/golang/dep] used.

$ dep ensure -update

Build

To build the binary (for linux):

$ GOOS=linux go build -o scheduler -a --ldflags '-extldflags "-static" -s -w' -tags netgo -installsuffix netgo .

to build a Docker container:

$ VERSION=0.0.2
$ docker build -t johscheuer/data-aware-scheduler:$VERSION .
$ docker push johscheuer/data-aware-scheduler:$VERSION

Run it

Prerequisites

• Running Quobyte Cluster (you can use this tool for a quick start)
• Running Kubernetes Cluster

Inside Kubernetes

Adjust config deployments/scheduler_config.yaml to your need:

kubectl create --namespace=kube-system -f deployments/scheduler_config.yaml
kubectl create --namespace=kube-system -f deployments/scheduler.yaml

Outside Kubernetes

At the moment you need a local mount of Quobyte with xattr enabled (-o user_xattr). As soon as the same information is available over the API this requierement drops.

Copy the example configuration and adjust it to your needs:

copy config.yaml.example config.yaml

Now start the Scheduler:

./scheduler --config=./config.yaml
