Docker, Linux

docker 설치

FileZilla myhome3.war 파일 이동

pwd
cd data

docker image ls
docker container ls
root 전환
cd ~calisws/data
ls 로 war 파일 확인

container 충돌이 나길래
docker container prune : 모든 작동중인 컨테이너 삭제
근데 안 지워지고 에러가 발생함

docker container ls -a 해보니 nginx 가 남아서 톰캣이 안됨
docker ps -a -q 죽이려는데 안 죽음

docker stop 컨테이너 ID or 이름
docker rm 컨테이너 ID or 이름
입력해주면 삭제 가능

docker run --name tomcat -p 9090:8080 tomcat:9.0
톰캣 입장

docker exec -it tomcat /bin/bash
cd data
docker cp myhome3.war tomcat:/usr/local/tomcat/webapps
docker container restart tomcat

접속 성공!
