docker 컨테이너 ip확인
docker network inspect bridge
docker-server 172.17.0.4
ansible-server 172.17.0.3
확인
/etc/ansible/hosts
[devops]
172.17.0.3
172.17.0.4
echo -e "[mygroup]\n172.17.0.3\n172.17.0.4" >> /etc/ansible/hosts
ansible
1.핑
ansible all -m ping
2.메모리 확인
ansible all -m shell -a "free -h"
3.파일 복사
ansible all -m copy -a "src=./test.txt dest=/tmp"
4.프로그램 설치(httpd)
ansible devops -m yum -a "name=httpd state=present"
설치된 프로세스 확인
yum list installed | grep httpd
ansible playbook
사용자가 원하는 내용을 미리 작성해 놓는 파일
(설치,파일전송, 서비스 재시작, 다수의 서버에 반복 작업 처리..)
예제1
/etc/ansible/hosts [mygroup] 내용추가
first-playbook.yml
---
- name: Add an ansible hosts
hosts: localhost
tasks:
- name: Add a ansible hosts
blockinfile:
path: /etc/ansible/hosts
block: |
[mygroup] 172.17.0.5
실행
ansible-playbook first-playbook.yml
같은 명령어 실행해도 ansible은 멱등성으로 중복처리 되지 않는다.
예제2
파일 복사
first-playbook-sample1.yml
현재 폴더에 sample.txt 만들어서 실행해 보자
- name: Ansible Copy Example Local to Remtoe
hosts: devops
tasks:
- name: copying file with playbook
copy:
src: ~/sample.txt
dest: /tmp
owner: root
mode: 0644
예제3
디렉터리 생성
톰켓 다운
first-playbook-sample2.yml
---
