서버에 Docker를 사용해서 Containerized app을 실행중이었는데, 어떤 이유에선지 실행중인 컨테이너가 다 내려가는 이상한 일이 발생했다. 그래서 다시 컨테이너를 마운트하는데 내가 사용하려는 포트를 이미 사용중이라고 나온다.

docker: Error response from daemon: driver failed programming external connectivity on endpoint katech-web (e2869131fb101ad044163633db6a1f72a8057a6bb39f9e42ce2f6684f1ac0cf3): Error starting userland proxy: listen tcp4 0.0.0.0:8824: bind: address already in use.
뭐지 싶어서 프로세스를 다 띄워 봤다.

이럴 땐, sudo를 사용해야했다.
