Cloudnet K8s Deploy 2주차 스터디를 진행하며 정리한 글입니다.
이번 포스팅에서는 Ansible 기초에 대해 알아보겠습니다.
Ansible이란
IT 인프라와 애플리케이션 운영 작업을 코드로 자동화하기 위한 오픈소스 도구입니다.
서버 설정, 애플리케이션 설치, 클라우드 리소스 생성 같은 반복 작업을 YAML 기반 플레이북으로 정의해 여러 환경에 동일하게 적용할 수 있습니다.
Ansible의 특징
1. Agentless
- 관리 대상 서버에 별도 에이전트 설치가 필요 없음
- SSH 기반으로 즉시 자동화 가능
- Puppet, Chef 대비 초기 도입과 운영 부담이 적음
2. 멱등성 (Idempotent)
- 동일한 작업을 여러 번 실행해도 항상 같은 결과
- 원하는 상태(desired state)를 기준으로 시스템을 유지
3. 쉬운 문법과 풍부한 모듈
- YAML 문법으로 사람이 읽고 쓰기 쉬움
- 파일 관리, 패키지 설치, 서비스 제어부터 클라우드 리소스 관리까지 다양한 모듈과 컬렉션 제공
Ansible 구성 요소 (커뮤니티 Ansible 기준)
전체 아키텍처
- Control Node + Managed Node
- 중앙 제어 노드에서 여러 관리 노드를 동시에 자동화
Control Node
- Ansible이 설치되어 실행되는 노드
- Linux 기반 환경이면 사용 가능
- Ansible은 Python 기반이므로 Python 필수
Managed Node
- Ansible이 제어하는 원격 서버
- Linux 또는 Windows 가능
- 에이전트 설치 불필요
- Control Node와 SSH 통신 가능, Python 설치 필요
Inventory
- 관리 대상 노드를 정의한 파일
- 호스트를 그룹 단위로 관리 가능
Module
- Ansible이 작업 수행 시 관리 노드로 전송(push) 하는 스크립트
- 작업 완료 후 자동 제거
- 시스템의 상태를 기준으로 동작
Plugin
- Ansible 제어 노드에서 실행
- 로깅, 데이터 변환, 인벤토리 연동 등 핵심 기능 확장
- 모듈을 보조하는 내부 확장 메커니즘
Playbook
- 실제 자동화를 정의하는 핵심 파일
- YAML 형식으로 작업을 순서대로 기술
Ansible 실습 환경
다음 서버를 생성하여 Ansible 실습을 진행하겠습니다.

Host 선정
인벤토리 파일
- 텍스트 파일로, Ansible이 자동화 대상으로 하는 관리 호스트를 지정
ansible config 적용 우선 순위
- 현재 프로젝트 디렉터리 내에 ansible.cfg 라는 앤서블 환경 설정 파일을 구성 시, -i 옵션을 사용하지 않아도 ansible.cfg 설정 파일에 정의된 인벤토리의 호스트 정보를 확인 가능
- ANSIBLE_CONFIG (environment variable if set)
- ansible.cfg (in the current directory)
- ~/.ansible.cfg (in the home directory)
- /etc/ansible/ansible.cfg

- 섹션 제목은 대괄호로 묶여 있으며, 기본적인 실행을 위해 다음 예제와 같이 [defaults]와 [privilege_escalation] 두 개의 섹션으로 구성
- default : ansible 작업을 위한 기본값 설정

- 호스트 변수: 특정 호스트에서만 사용하는 변수
- 그룹 변수: 인벤토리 정의된 호스트 그룹에 적용하는 변수
- 작업 변수: 플레이북의 수행 결과를 저장 후 후속 작업에 사용할 때 사용된다.
변수 우선 순위
- 추가변수
- 플레이 변수
- 호스트 변수
