Actions for Kubernetes Master:

The following files need IP addresses changed: 
/etc/kubernetes/admin.conf
/etc/kubernetes/controller-manager.conf 
/etc/kubernetes/kubelet.conf
/etc/kubernetes/scheduler.conf
/etc/kubernetes/manifests/etcd.yaml
/etc/kubernetes/manifests/kube-apiserver.yaml
Existing certificates are deleted: 
cd /etc/kubernetes/pki
rm -rf apiserver.* apiserver-kubelet-client.*
New certificates are created (this stage may produce errors but they can be ignored): 
sudo kubeadm init phase certs apiserver-kubelet-client
sudo kubeadm init phase certs apiserver

sudo systemctl restart kubelet
The current config file is moved to the user’s home directory for access: 
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

​
Actions for MongoDB:

Connect to MongoDB: 
mongosh mongodb://<YOUR_NEW_MONGO_IP_ADDRESS>:25080 --authenticationDatabase "admin" -u "apinizer" -p
New IP settings are applied with the “force” option: 
cfg = rs.conf()
cfg.members[0].host = "<YOUR_NEW_MONGO_IP_ADDRESS>:25080"
rs.reconfig(cfg, {force:true})
