This quickstart helps to install a Kubernetes cluster hosted on GCE, Azure, OpenStack, AWS, vSphere, Oracle Cloud Infrastructure (Experimental) or Baremetal with Kubespray.
Provision servers with the following requirements:
ansible_become flag or command parameters
-b should be specified
Kubespray provides the following utilities to help provision your environment:
Kubespray provides the ability to customize many aspects of the deployment:
Kubespray customizations can be made to a variable file. If you are just getting started with Kubespray, consider using the Kubespray defaults to deploy your cluster and explore Kubernetes.
Next, deploy your cluster:
Cluster deployment using ansible-playbook.
ansible-playbook -i your/inventory/hosts.ini cluster.yml -b -v \
Large deployments (100+ nodes) may require specific adjustments for best results.
Kubespray provides a way to verify inter-pod connectivity and DNS resolve with Netchecker. Netchecker ensures the netchecker-agents pods can resolve DNS requests and ping each over within the default namespace. Those pods mimic similar behavior of the rest of the workloads and serve as cluster health indicators.
Kubespray provides additional playbooks to manage your cluster: scale and upgrade.
You can add worker nodes from your cluster by running the scale playbook. For more information, see “Adding nodes”. You can remove worker nodes from your cluster by running the remove-node playbook. For more information, see “Remove nodes”.
You can upgrade your cluster by running the upgrade-cluster playbook. For more information, see “Upgrades”.
You can reset your nodes and wipe out all components installed with Kubespray via the reset playbook.
Caution: When running the reset playbook, be sure not to accidentally target your production cluster!
