Copy docker images tarball to the remote server

scp <folder_with_images>/*.tar <user>@<server>:<path>/<to>/<remote>/<folder>

Ensure docker is started

systemctl status docker

In case docker is not started

systemctl enable docker && systemctl start docker

Load docker images on remote server

For Centos7, enable sysctl configuration

edit `/etc/sysctl.conf`

vi /etc/sysctl.conf

modify

net.ipv4.ip_forward = 0 to net.ipv4.ip_forward = 1

Append

net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1

Reload properties

sysctl -p

Your Kubernetes master has initialized successfully!

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
    http://kubernetes.io/docs/admin/addons/

You can now join any number of machines by running the following on each node:

kubeadm join --token=<token> <master-ip>
# Copy the previous line
...

Network configuration

Download weave plugin configuration (with internet)

wget https://git.io/weave-kube
mv weave-kube weave-kube.yml

Copy weave plugin configuration

scp <folder_with_weave_yml>/weave-kube.yml <user>@<server>:<path>/<to>/<remote>/<folder>

Apply plugin

kubectl apply -f <folder_with_weave_yml>/weave-kube.yml

Fix kube-proxy problem

kubectl -n kube-system get ds -l "component=kube-proxy" -o json | jq ".items[0].spec.template.spec.containers[0].command |= .+ [\"--proxy-mode=userspace\"]" | kubectl apply -f - && kubectl -n kube-system delete pods -l "component=kube-proxy"

On Node

kubeadm join --token
