The kubernetes.core collection offers several modules and plugins for orchestrating Kubernetes.

Ansible addresses these challenges by automating cluster provisioning, enforcing configurations, and managing application deployments across Kubernetes environments. By pairing Ansible with Kubernetes, organizations can combine the strengths of both—taking advantage of Ansible’s library of modules, human-readable playbooks, and support for complex tasks like virtual machine migration.

January 1, 2024 - Also in the blog series about virtualization mentioned above I created a Python virtual environment with Ansible installed for my Physical Hosts in /opt/scripts/ansible/k8s-01_phy (/opt/scripts/ansible is my base directory for everything Ansible related). Now I’ll create one for my Virtual Machines in /opt/scripts/ansible/k8s-01_vms. So in /opt/scripts/ansible directory I execute the following command: ... That creates a directory called k8s-01_vms. k8s-01 is for “Kubernetes Cluster 01” and vms for “Virtual Machines”. So everything related to the “Physical Hosts” will be managed by k8s-01_phy (just FYI, not relevant for this blog series) and every thing related to the “Virtual Machines” which runs on the Physical Hosts will go into k8s_01_vms.

October 10, 2025 - Ansible integrates into this ecosystem by focusing on orchestrating initial setup tasks such as configuring Kubernetes clusters, setting up network policies, storage solutions, and other cloud infrastructure essentials.

June 19, 2024 - Ansible makes editing files easy so I’m going to take advantage of it. My initial version of this script was longer, but I took this opportunity to move up the apt repo configs, consolidate the installations, and shorten everything. This is where we really start building the Kubernetes cluster. In 5 steps, I do the following: Initialize the Kubernetes cluster with kubeadm init and quite a few options (more on this below)

The collection includes a variety of Ansible content to help automate the management of applications in Kubernetes and OpenShift clusters, as well as the provisioning and maintenance of clusters themselves.

String d = "docs/tutorials/jenkins/ansible-kubernetes" pipeline { agent any parameters { choice(name: 'ANIMAL', choices: ['cat', 'cow', 'dog', 'lion', 'pig'], description: 'Tag to use for deployment image') } stages { stage("deploy") { agent { dockerfile { dir "$d" reuseNode true } } environment { K8S_AUTH_KUBECONFIG = credentials('kubeconfig') KUBECONFIG = credentials('kubeconfig') } steps { sh """ ansible-playbook $d/deploy-to-kubernetes.yml --extra-vars "animal=${params.ANIMAL}" ./$d/wait-until-service-up.sh """ } } } } After you have created the pipeline, try to execute it by clicking Build Now. The pipeline should have deployed the example application into the Kubernetes cluster with the default image tag (cow) defined in the deploy-to-kubernetes.yml Ansible playbook.

August 4, 2025 - The kubelet acts as the node agent, communicating with the control plane and managing container lifecycle. The kube-proxy handles network routing for services, and the CNI plugin manages pod-to-pod networking across the cluster. To understand better what Ansible code does, instead of adding the code here, I decided to place the sequence diagram of the steps, so that we can clearly see how the interaction occurs between the ansible code and the remote virtual machine. To deploy the kubernetes, three roles are created:

February 18, 2020 - In Ansible 2.10, the code for anything not deemed 'core' (which includes the majority of plugins and modules that are currently stored in the ansible/ansible repository) will be moved into separate collection repositories, with the majority moving into a 'general' collection. As time goes on, some of the more actively-maintained content in the general collection may be extracted into more specific collections. Seeing the huge increase in Kubernetes adoption—often by teams using some automation tooling already—I decided to help organize the Kubernetes Working Group, and get all the current Kubernetes-related plugins and modules extracted into their own, dedicated Kubernetes collection.
