나한테 제일 만만한거 놈 톰캣을 Docker 이미지로 불러와서 띄워보겠다.

1. tomcat 이미지 유무 확인

[albert@docker ~]$ docker search tomcat

2. 이미지 있는걸 확인하고 다운하기

[albert@docker ~]$ docker pull tomcat

Status: Downloaded newer image for tomcat:latest
docker.io/library/tomcat:latest

3. 이미지가 정상 다운되었는지 리스트 확인

[albert@docker webapps]$ docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
tomcat        latest    51adadb96917   8 hours ago     481MB
hello-world   latest    feb5d9fea6a5   17 months ago   13.3kB

4. 정상 다운되었으니 tomcat 컨테이너 실행 및 실행상태 확인

[albert@docker ~]$ docker run -d -t -p 8080:8080 --name tomcat tomcat:latest
55607934c6f495a4fdd7b281e2af987540c12250dd7392f367305788b1d2f17a
[albert@docker ~]$ docker ps
CONTAINER ID   IMAGE           COMMAND             CREATED         STATUS         PORTS                                       NAMES
55607934c6f4   tomcat:latest   "catalina.sh run"   8 seconds ago   Up 7 seconds   0.0.0.0:8080->8080/tcp, :::8080->8080/tcp   tomcat

5. 웹브라우저에서 확인(확인하면 404가뜸 원인은 webapp 디렉토리가 깡통임)

6. 컨테이너 않으로 샘플 파일 옮기기

(난 그냥 톰캣다운했을때 webapp 않의 default ROOT폴더를 복사해 넣어줬음)

[albert@docker webapps]$ docker cp ROOT/ 55607934c6f4:/usr/local/tomcat/webapps
Preparing to copy...
Copying to container - 32.77kB
Copying to container - 65.54kB

Copying to container - 131.1kB
Copying to container - 160.3kB
Successfully copied 160.3kB to 55607934c6f4:/usr/local/tomcat/webapps

7. 컨테이너 않으로 들어가 정상적으로 ROOT폴더가 webapp 밑에 들어갓는지 확인

[albert@docker webapps]$ docker exec -it 55607934c6f4 /bin/bash
root@55607934c6f4:/usr/local/tomcat' ls
bin           conf             lib      logs            NOTICE     RELEASE-NOTES  temp     webapps.dist

8. 정상적으로 웹브라우저에서 화면이 뜨는걸 볼 수 있음
