Welcome to the exciting world of Ansible for Kubernetes! In this comprehensive guide, we’ll explore how to utilize Ansible alongside Kubernetes to create seamless deployment and automation processes. Through practical examples, you will gain insight into how these technologies can work together effectively.

Getting Started with Ansible for Kubernetes

This article is based on the [Ansible for Kubernetes](https://www.ansibleforkubernetes.com) repository created by Jeff Geerling. The repository contains a collection of Ansible and Kubernetes examples to aid in understanding core concepts. Here’s how to leverage this repository:

Examples and Their Structure

The repository is structured into various chapters, each containing specific examples designed to demonstrate different functionalities. Here is a high-level overview:

• Chapter 1 – hello-go: A simple Go application illustrating stateless application deployment in a Kubernetes cluster.
• Chapter 2:
  • hello-ansible: An introductory Ansible playbook for task-based automation.
  • hello-go-automation: Automation of the Hello Go app deployment using Ansible.
• Chapter 3:
  • ansible-containers: Building a container image for the Hello Go app with Ansible.
  • ansible-solr-container: End-to-end playbook for building an Apache Solr container without a Dockerfile, leveraging Ansible’s Docker connection plugin.
• Chapter 4 – cluster-local-vms: A Kubernetes cluster running on VirtualBox VMs using Vagrant and Ansible.
• Chapter 5 – cluster-aws-eks: An AWS EKS cluster setup using Ansible to apply CloudFormation templates.
• Chapter 7 – testing-molecule-kind: Environment for developing and testing Ansible playbooks against a Kind Kubernetes cluster.

Understanding Code through Analogy

To understand the code snippets and playbooks in this repository, let’s think of a chef preparing different dishes in a restaurant. Each chapter represents a unique menu item:

• Chapter 1 – hello-go: The chef prepares a simple salad (a basic application) that demonstrates how to serve a dish quickly with minimal ingredients (running a stateless application).
• Chapter 3 – ansible-containers: Here, the chef learns how to create a meal (container image) using multiple cooking techniques (Ansible playbooks) rather than sticking to a single recipe (Dockerfile).
• Chapter 5 – cluster-aws-eks: Imagine a chef setting up a large banquet (AWS EKS cluster), coordinating a whole team of cooks and servers (Ansible tasks) to create a grand dining experience (functioning Kubernetes environment).

Troubleshooting Tips

While working with Ansible for Kubernetes, you may encounter a few hurdles. Here are some common troubleshooting ideas:

• Ensure that your Kubernetes cluster is properly configured and running before executing Ansible playbooks.
• Double-check your Ansible inventory settings to confirm that they are set according to your local environment.
• If you encounter permission issues, consider adjusting your Kubernetes service account roles.
• In case of connectivity issues, verify your networking setup between Ansible and Kubernetes.
