tags: NVIDIA, Kubernetes, Docker, Kubernetes-dashboard

HW Equipment

Hardware System: SCB 1921B-AA1 OS: Ubuntu 18.04 LTS, kernel 5.4.0-42 GPU: NVIDIA GEFORCE GTX 1050

Docker Installtion

Install the prerequsities:

$ sudo apt-get update
$ sudo apt-get install \
   apt-transport-https \
   ca-certificates \
   curl \
   gnupg-agent \
   software-properties-common

Add gpg key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo apt-key fingerprint 0EBFCD88

Make sure result is like this:
9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

Add repository:

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
$ sudo apt-get update

Docker Installtion:

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

Check the Docker Version:

$ docker version

Now Installtion the NVIDIA Driver

download .run installing driver file from NVIDIA website:

Note: Select your model of Nvida and OS before Downlaoding: https://www.nvidia.com/Download/index.aspx?lang=en-us

before installtion blacklist nouveau driver

create a file:

$ sudo vim /etc/modprobe.d/blacklist-nouveau.conf

in blacklist-nouveau.conf

blacklist nouveau
options nouveau modeset=0

save the file and exit

final:

$ sudo update-initramfs -u
$ sudo reboot

After restarting, we can use the following command to confirm whether Nouveau has stopped working:

lsmod | grep nouveau

If nothing is printed, then congratulations! You have disabled Nouveau's kernel driver. Now we can try again to see if we can install Nvidia's official driver

make it excutable

$ chmod +x NVIDIA-Linux-x86_64-460.32.03.run //make it executable

install gcc and make

$ sudo apt-get install gcc make

installing nvidia driver

$ ./NVIDIA-Linux-x86_64-460.32.03.run //name of file may be different, depends on the version which you download from

in .run, there're some warnings, just choose continue installing item and finish the installing procedure

and

$ reboot

after reboot, press nvidia-smi to see the driver is OK or not

$ nvidia-smi

The output would be like this

Kubernetes Installtion

Do the SWAPOFF:

$ sudo su
$ swapoff –a

**Optional Step: $ nano /etc/fstab add # into the following line like this: #UUID=45fc9fe6-6500-4bca-864e-1effad4764b3 and save **

Install the prerequsities:

$ sudo apt-get update
$ sudo apt-get install -y apt-transport-https ca-certificates curl
$ curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -

Adding the kubernetes repository into the update list:

cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
EOF

update:

$ sudo apt-get update

install kubeadm kubectl kubelet:

$ apt-get install -y kubelet kubeadm kubectl

check the versions

$ docker -v
Docker version 17.03.2-ce, build f5ec1e2
$ kubectl version
Client Version: version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.1", GitCommit:"4ed3216f3ec431b140b1d899130a69fc671678f4", GitTreeState:"clean", BuildDate:"2018-10-05T16:46:06Z", GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?
$ kubeadm version
kubeadm version: &version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.1", GitCommit:"4ed3216f3ec431b140b1d899130a69fc671678f4", GitTreeState:"clean", BuildDate:"2018-10-05T16:43:08Z", GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
$ kubelet --version
Kubernetes v1.12.1

Set up the environment driver in config file:

$ gedit /etc/systemd/system/kubelet.service.d/10.kubeadm.conf

Start cluster:

$ kubeadm init --pod-network-cidr=10.244.0.0/16
*###This will take 3-4 mintues##*

Run the following commands as non-root user:

$ mkdir -p $HOME/.kube
$ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
$ sudo chown $(id -u):$(id -g) $HOME/.kube/config

cluster information:

$ kubectl cluster-info
Kubernetes master is running at https://10.132.0.2:6443
KubeDNS is running at https://10.132.0.2:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

Install CNI (I prefer weave)::

$kubectl apply -f “https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d ‘\n’)”

clusterrole.rbac.authorization.k8s.io/weave-net created
clusterrolebinding.rbac.authorization.k8s.io/weave-net created
. 
.
.

Confirm with those commands:

$ kubectl get no -o wide
NAME            STATUS   ROLES    AGE     VERSION   INTERNAL-IP   EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION    CONTAINER-RUNTIME
kube-master-1   Ready    master   9m15s   v1.12.1   10.132.0.2    <none>        Ubuntu 16.04.5 LTS   4.15.0-1021-gcp   docker://17.3.2

Deploy the Dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

Now we have to creat the admin-user for access the dashboard

kubectl apply -f https://gist.githubusercontent.com/chukaofili/9e94d966e73566eba5abdca7ccb067e6/raw/0f17cd37d2932fb4c3a2e7f4434d08bc64432090/k8s-dashboard-admin-user.yaml
