July 18, 2024 - This repository provides Ansible Playbooks To setup Kubernetes HA on Redhat Enterprise Linux 7. The playbooks are mainly inspired by Kubeadm documentation and other ansible tentatives on github. The playbooks could be used separately or as one playbook for a fully fledged HA cluster.

Build a Kubernetes cluster using kubeadm via Ansible. - kairen/kubeadm-ansible

November 8, 2024 - Finally, add_worker_node.yaml is imported to join the worker nodes to the cluster, allowing them to participate in workload distribution. This structure provides clear, step-by-step automation for creating a Kubernetes cluster. It handles everything from initial setup to cluster-wide integration, ensuring a streamlined, repeatable deployment process. By following this guide, we’ve automated the setup of a Kubernetes cluster using Ansible and kubeadm, streamlining what would otherwise be a complex and time-consuming process.

June 19, 2024 - In 5 steps, I do the following: ... (more on this below) ... Generate the join command with kubeadm token create --print-join-command and save it in the variable {{ join_command_output }}...

February 2, 2022 - To start using your cluster, you need to run the following as a regular user: mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config [...] Then you can join any number of worker nodes by running the following on each as root: kubeadm join 192.168.178.180:6443 --token 7k2z9o.atvgwvywu5pkd5w3 \ --discovery-token-ca-cert-hash sha256:9f00a315991af8873e050862a8884d8300424e481721d96afe19cdf0d236270f

2 weeks ago - You can install and use kubeadm on various machines: your laptop, a set of cloud servers, a Raspberry Pi, and more. Whether you're deploying into the cloud or on-premises, you can integrate kubeadm into provisioning systems such as Ansible or Terraform.

modular, clean code, supporting multiple activies by using ansible tags (e.g. add/reset a subgroup of nodes). optionally help configuring container engine (e.g. docker) This project targets to get a fully working environment in matter of minutes on any hw: baremetal, vms (vsphere, virtualbox), etc. k8s version upgrades: while many of its roles can be used for an upgrade, upgrade should be done using kubeadm tool.

October 10, 2025 - Let’s create kube_workers.yml under ~/ansible/playbooks/.

Whether the particular server will serve as a Kubernetes control_plane (default) or node. The control plane will have kubeadm init run on it to intialize the entire K8s control plane, while nodes will have kubeadm join run on them to join them to the control_plane.

April 25, 2019 - Kubeadm automates the installation and configuration of Kubernetes components such as the API server, Controller Manager, and Kube DNS. It does not, however, create users or handle the installation of operating-system-level dependencies and their configuration. For these preliminary tasks, it is possible to use a configuration management tool like Ansible or SaltStack.
