Build kubernetes scheduler

Based on Kubernetes 1.15.3

set up kubernetes clusters

git clone https://github.com/fishercht1995/progress-based-k8s-scheduler.git

There is detailed version from Shaolun Zhang https://github.com/zsl3203/summer

in master node

deploy k8s system

./progress-based-k8s-scheduler/kubernetes/deploy.sh

init k8s in the master node, and get token

./progress-based-k8s-scheduler/kubernetes/init.sh

in worker node

deploy k8s system

./progress-based-k8s-scheduler/kubernetes/deploy.sh

Using Token get in the first step, so the worker will join into k8s cluster

set up prometheus and grafana monitor system

in master

./progress-based-k8s-scheduler/pgmonitor/master.sh

Dashboards

set up nfs system

in both master and worker nodes

get externel ip address

dig +short myip.opendns.com @resolver1.opendns.com

on master

sudo apt-get update
sudo apt install nfs-kernel-server
sudo mkdir -p /mnt/linuxidc
sudo chown nobody:nogroup /mnt/linuxidc
sudo chmod 777 /mnt/linuxidc

sudo nano /etc/exports

/mnt/linuxidc masterIP(rw,sync,no_subtree_check)
/mnt/linuxidc client1IP(rw,sync,no_subtree_check)
/mnt/linuxidc client2IP(rw,sync,no_subtree_check)

sudo exportfs -a
sudo systemctl restart nfs-kernel-server

on worker

sudo apt-get update
sudo apt-get install nfs-common
sudo mkdir -p /mnt/linuxidc_client

sudo mount master_ip:/mnt/linuxidc /mnt/linuxidc_client

set up configuration in kubernetes

kubectl edit clusterrole system:kube-scheduler

add my-scheduler in resourceNames:
