도커 설치 톰캣
방법 1. Dockerfile을 통해 빌드
Dockerfile 만들기
먼저 나중에 관련 내용을 저장할 tomcat 디렉터리를 만듭니다.
php@php:~$ mkdir -p ~/tomcat/webapps ~/tomcat/logs ~/tomcat/conf
webapps 디렉토리는 Tomcat 컨테이너가 구성한 애플리케이션 디렉토리에 매핑됩니다.
logs 디렉토리는 Tomcat 컨테이너의 로그 디렉토리에 매핑됩니다.
conf 디렉토리의 구성 파일은 구성 파일에 매핑됩니다.
생성된 tomcat 디렉토리에 들어가서 Dockerfile을 생성합니다
