Just a collection of notes about Ansible. Ansible is a contraction of “answerable”. In the novel Rocannon’s world by Ursula K Leguin it is an instant comms system 🙂
- Ansible is a python application for configuration management, bought by Redhat in 2015.
- Red Hat Automation Controller (RHAC) provides REST API & Web UI for central management & reporting.
- Ansible AWX is an open source version of RHAC.
- Puppet, Chef, Terraform are alternatives to Ansible.
- Uses YAML (YAML aint markup language) configuration files to declaratively describe configuration of managed nodes.
Yaml
