[Docker] 도커파일 Apache-Tomcat 망분리 구축 및 Zabbix-Agent 설치 간단 예제 (Apache Dockerfile, Tomcat Dockerfile, Zabbix-agent Dockerfile)

 

• 도커 Apache-Tomcat 망분리 구축 및 Zabbix-Agent 설치 코드 (Apache Dockerfile, Tomcat Dockerfile, Zabbix-agent Dockerfile)

기존에 올렸던 포스팅(https://nirsa.tistory.com/132?category=876464)을 도커파일로 변환시켜서 사용하는 예제 입니다. 셋팅자체는 위의 포스팅과 거의 똑같고 서버 IP 등의 정보는 변경해서 사용하시면 됩니다.

기본적으로 연결하기 위한 간단한 설정만 적용된 apache, zabbix-agent 두가지 Dockerfile을 만든 후 docker-compose를 사용하여 실행 했습니다. 간단히 작성된것이므로 볼륨등을 추가적으로 설정 후 사용하시는게 좋습니다. 만약, 소스코드를 따로 설정해야할 경우 COPY 또는 VOLUMES 등을 이용하면 됩니다.
