Ansible is a powerful open-source automation tool that simplifies the management of complex IT environments. Its agentless architecture and straightforward YAML syntax make it an attractive choice for configuration management, application deployment, and task automation. However, as environments grow in size and complexity, scaling Ansible effectively becomes crucial. This article explores strategies and best practices for using and scaling Ansible in large environments.

When managing remote systems with Ansible, tasks are generally executed on target hosts over SSH. However, there are scenarios where you might want to execute certain tasks on the local machine (the control node) instead of the remote hosts. Ansible provides built-in mechanisms for delegating tasks to the local host or other specific hosts while running playbooks remotely.

In today’s security-conscious IT environments, sensitive data like passwords, API keys, and certificates must be handled with care. Ansible offers a solution through Ansible Vault – a feature that allows you to encrypt sensitive information. However, as environments become more complex, managing a single vault can quickly become cumbersome. This is where Ansible Vault IDs come into play, enabling you to manage different tiers of secrets with ease.

Podman’s integration with Kubernetes through the podman kube play command allows users to create pods, containers, and volumes from Kubernetes YAML files. This command reads the structured file and recreates the described resources, starting the containers within a pod and outputting the ID of the new pod or the name of the new volume.
Sometimes you must create your own Podman images. Building your own Podman images allows for greater customization, control, consistency, and organizational efficiency compared to using only public images. The investment upfront can pay dividends in the long run through improved security, consistency, and maintainability of your container infrastructure.

Podman volumes allow you to persist data outside of the container’s file system. This is particularly important when you need to ensure that your application data is not lost when a container is stopped, restarted, or removed. In this lesson you will learn the basics of managing Podman volumes in the command line.
Continue reading “Podman Basics 06: Podman Volumes”
After installing Podman you have to know and understand some of the terminology. Understanding the basic jargon of containerization will help you start with this lesson, and it will be beneficial later on too. You will learn about the image registries, images and containers in this lesson. You will take a look at how to pull, run and manage them.
