![Install Kubernetes Cluster on Azure Platform using
KubeSpray
Prerequisite:
1. Azure Account
Setup system:
1. Install azure cli (choose any method of your choice)
https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest
2. Install ansible
We can install it from different ways but i install using pip
pip3 install ansible>=2.4.0
pip3 install ansible-modules-hashivault>=3.9.4
Installation:
1. Clone Code:
git clone https://github.com/kubernetes-incubator/kubespray.git
2. Configure Files:
a. cd kubespray
b. cp -r inventory/sample/ inventory/azcluster
c. Add Azure Detail
vi ./inventory/azcluster/group_vars/all.yml
Note: Check Appendix-1 for more Detail
d. Configure Node related info
vi contrib/azurerm/group_vars/all
e. Create infra
cd /kubespray/contrib/azurerm
./apply-rg.sh op-np [op-np is resource group in my case]
f. Create Inventory file
./generate-inventory.sh op-np
cd ..
check inventory file at vi contrib/azurerm/inventory
g. Create New Node (optional)
edit file vi contrib/azurerm/group_vars/all
repeat step e & f](https://image.slidesharecdn.com/installkubernetesclusteronazureplatformkubespray-180908135437/85/Install-Kubernetes-Cluster-on-Azure-Platform-using-kubespray-1-320.jpg)
![h. Delete infra
cd /kubespray/contrib/azurerm
./clear-rg.sh op-np
3. Configure Kubernetes
a. First Time
ansible-playbook -i contrib/azurerm/inventory -u clusteradmin --become -e
"@inventory/azcluster/group_vars/all.yml" -e
kube_network_plugin=flannel -e network_plugin=flannel -e
dns_domain=cluster.local cluster.yml -b -v --private-key=privatekey
b. Add Node [Follow steps define in 2g section before doing this]
ansible-playbook -i contrib/azurerm/inventory -u clusteradmin --become -e
"@inventory/azcluster/group_vars/all.yml" -e
kube_network_plugin=flannel -e network_plugin=flannel -e
dns_domain=cluster.local scale.yml --limit nodename2 -b -v --private-
key=privatekey
c. Delete Node
ansible-playbook -i contrib/azurerm/inventory -u clusteradmin --become -e
"@inventory/azcluster/group_vars/all.yml" remove-node.yml -b -v --
private-key=privatekey --extra-vars "node=nodename1,nodename2”](https://image.slidesharecdn.com/installkubernetesclusteronazureplatformkubespray-180908135437/85/Install-Kubernetes-Cluster-on-Azure-Platform-using-kubespray-2-320.jpg)
