<마운트 실습 :: 마운트를 이용한 NginX 로그 기록 관리>
로그 기록 업데이트 파일 마운트
- 로그 기록을 마운트 해 자동적으로 업데이트 > 로그 기록 관리
- 로그 기록 파일 저장 위치: /Labs/ch06/nginx-log
1. 로그 기록 저장 폴더 생성: nginx-log
ubuntu@host1:~/Labs/ch06$ mkdir nginx-log
ubuntu@host1:~/Labs/ch06$ ls
bind01 bind02 **nginx-log**
2. 로그 기록을 가져올 컨테이너 생성
- 마운트
- 호스트: ${PWD}/nginx-log
- 컨테이너: /var/log/nginx
- 포트 포워딩 8001(호스트):80(컨테이너)
ubuntu@host1:~/Labs/ch06$ docker container run -d --name=myweb -v ${PWD}/nginx-log:/var/log/nginx -p 8001:80 nginx:1.25.0-alpine
8def3765c57b8e0c16a06dac3119b63ce16c70657c56f724f1e01d03e010aec4
>> nginx 웹 서버가 8001 포트에서 실행되며, 로그는 호스트의 ${PWD}/nginx-log 디렉터리에 저장
ubuntu@host1:~/Labs/ch06$ docker container ps
