Ansible-Core is the minimalist, yet powerful, foundation of the Ansible automation ecosystem. It provides the essential command-line tools and the underlying architecture required for running Ansible playbooks and managing automation tasks. This article explores what Ansible-Core is, its features, benefits, and how it fits into the broader Ansible ecosystem.
What is Ansible-Core?
Ansible-Core, formerly known as Ansible-Base in version 2.10, is the fundamental package for Ansible. It includes the core language and runtime required to execute Ansible playbooks and manage automation tasks. Unlike the Ansible community package, which includes a wide range of modules and plugins, Ansible-Core provides only the essential components, allowing users to install additional collections as needed.

3. Command-Line Tools: Ansible-Core includes crucial command-line tools such as ansible-playbook, ansible-doc, and others. These tools are essential for writing, testing, and running Ansible playbooks.
4. Extensibility: Ansible-Core's architecture supports extensions through Ansible collections, enabling users to expand its functionality as needed. This makes it suitable for both simple and complex automation tasks.
5. Stable and Reliable: Maintained by the Ansible Engineering Team, Ansible-Core focuses on stability and reliability, making it ideal for production environments where consistency and dependability are crucial.
