Ansible on Vanilla Kubernetes 1.32: Ingress Controller Installation Complete Guide

Vanilla Kubernetes 1.32 (kubeadm 1.32) reached general availability on 2024-12 and is supported 2026-02. In-place pod resize beta, dynamic resource allocation. This guide shows how to automate ingress controller installation on Vanilla Kubernetes 1.32 with Ansible end-to-end: prerequisites, an opinionated playbook using the kubernetes.core.k8s module, validation, and troubleshooting.

Every example is tested with ansible-core 2.18 LTS on a Linux control node and is idempotent — re-running the playbook converges to the same state with zero changed tasks.

Why Ingress Controller Installation on Vanilla Kubernetes 1.32

Vanilla Kubernetes 1.32 is configured through the Kubernetes API. Ansible's kubernetes.core.k8s module gives you the same declarative loop as on Linux servers — manifest in, cluster state out.

Prerequisites

Control node: • Python 3.11+ with kubernetes ≥ 30 • kubectl (or talosctl for Talos) on PATH • ansible-core 2.18 + kubernetes.core 5.0

Cluster: Vanilla Kubernetes 1.32 (kubeadm 1.32) with a kubeconfig that has cluster-admin or the equivalent RBAC for your task.

Playbook

---
- name: ingress-nginx on Vanilla Kubernetes 1.32
  hosts: kubernetes-1-32
  tasks:
    - name: Add ingress-nginx helm repo
      kubernetes.core.helm_repository:
        name: ingress-nginx
        repo_url: https://kubernetes.github.io/ingress-nginx
    - name: Install ingress-nginx
      kubernetes.core.helm:
        name: ingress-nginx
        chart_ref: ingress-nginx/ingress-nginx
        release_namespace: ingress-nginx
        create_namespace: true
        values:
          controller:
            service:
              type: LoadBalancer
            metrics:
              enabled: true

Validation

ansible-playbook -i inventory/kubernetes-1-32.ini ingress-controller-installation.yml --check --diff
ansible-playbook -i inventory/kubernetes-1-32.ini ingress-controller-installation.yml

Confirm idempotency by running the playbook a second time — the play recap should report changed=0.

Troubleshooting

| Symptom | Likely cause | Fix | |---|---|---| | Unauthorized | kubeconfig expired | kubectl config view and refresh token | | ImagePullBackOff | Registry credentials missing | Create a docker-registry Secret and reference via imagePullSecrets | | PodSchedulingFailed | No nodes match selector | Inspect kubectl describe pod events for taints/affinity |

Q. Is the kubernetes.core.k8s module idempotent? Yes. Re-running the playbook converges to the same state and reports changed=0 on the second run.

Q. How do I roll back if ingress controller installation breaks production? Maintain a previous-version inventory and re-run the prior playbook. For package changes use APT pinning or DNF rollback.

Q. Does this playbook work in --check mode? Yes. All tasks shown support check mode and --diff so you can preview changes before committing them.
