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.

One of the key features that contributes to Ansible’s popularity is its extensive ecosystem of community-contributed content, known as Ansible Galaxy. Ansible Galaxy is a hub for discovering and sharing Ansible roles, which are reusable automation components that encapsulate tasks, variables, and other Ansible functionality. These roles are created and shared by the Ansible community, allowing users to quickly find and incorporate pre-built automation into their own projects.

In configuration management and automation, templates play a very important role. They allow you to create dynamic, reusable file content by using variables and other expressions in text files. In the context of Ansible, the template engine of choice is Jinja2. You will create mostly configuration templates in Jinja2 format, and address them in your playbooks with the ansible.builtin.template module. In this lesson you will also learn how can you use expressions in the template files.
