March 12, 2026 - custom_cni : You can specify some manifests that will be applied to the clusters to bring you own CNI and use non-supported ones by Kubespray. See tests/files/custom_cni/README.md and tests/files/custom_cni/values.yamlfor an example with a CNI provided by a Helm Chart.

February 4, 2026 - As you can see, this file lists all the EC2 instances and their role in the cluster. For example, the content above shows that we will install the Kube control components and etcd into ip-10-250-193-75.us-west-2.compute.internal. ... Now that our EC2 instances are available, we can use Kubespray to deploy a Kubernetes cluster.

December 15, 2022 - By applying the playbook - Ansible jargon for the installation/setup scripts that consume your configuration - the desired state is manifested on the target server. Using Kubespray means to manifest your cluster as true Infrastructure as code: All subsequent runs lead to the very same desired state.

Deploy a Production Ready Kubernetes Cluster

For this article, we’ll use an AWS EC2 VM as the infrastructure. You can reference sample Terraform scripts within your newly-extracted Kubespray folder by navigating to ~/Projects/kubespray_workspace/kubespray-2.15.1/contrib/terraform/aws/.

By default, Kubespray configures kube_control_plane hosts with insecure access to kube-apiserver via port 8080. A kubeconfig file is not necessary in this case, because kubectl will use http://localhost:8080 to connect. The kubeconfig files generated will point to localhost (on kube_control_planes) and kube_node hosts will connect either to a localhost nginx proxy or to a loadbalancer if configured.

1 week ago - Set ANSIBLE_CONFIG environment variables to Kubespray’s ansible configuration file as follows: ... Check that you have basic SSH connectivity to the nodes. You can do this by running the following ansible command. ... You should see similar to the following figure if all nodes are reachable. master-0.example.com | SUCCESS => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": false, "ping": "pong" } worker-0.example.com | SUCCESS => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": false, "ping": "pong" } worker-1.example.com | SUCCESS => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": false, "ping": "pong" } worker-2.example.com | SUCCESS => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python3" }, "changed": false, "ping": "pong" }

February 7, 2024 - Clone the Kubespray GitHub repository. ... Create an inventory file for Ansible. (See more details here). In the following example, the HOST_PREFIX will set the nodes name prefix to dcmp-cp- and KUBE_CONTROL_HOSTS will mark all 3 nodes to be control nodes.

June 4, 2023 - Follow the following steps to set up Kubespray on your Ansible host. In this example, the Ansible host is the Ubuntu 20.04 system with the hostname ansible-host.

Here are 3 examples: 3 vms, all 3 have etcd installed, all 3 are nodes (running pods), 2 of them run master components ... You should have at least 3 nodes but you can spawn only one instance for tests purposes.

September 16, 2020 - Before beginning the demonstration, I want to remind you that kubespray is under active development, so make sure to use a stable release version. In this demo, I created three VMs consisting of one master and two nodes on AWS compute instances.
