[Docker] Error response from daemon: driver failed programming external connectivity on endpoint, port is already allocated 대처 방법 (port 강제 종료)
Greenplum and PostgreSQL Database 2018. 9. 24. 23:30
도커 컨터이너를 잘 사용하다가 컴퓨터를 껐다가 다시 켜고서 docker start 를 다시 하면 포트가 이미 할당되어 있다(port is already allocated) 면서 에러가 발생하는 경우가 있습니다.
저의 경우, 도커로 Greenplum Database + MADlib + PL/R + PL/Python 설치되어 있는 gpdb-ds 도커 컨터이너를 실행하려고 하니 아래와 같은 에러 메시지가 떴습니다.
(추측컨데, docker를 정상적으로 종료하지 않고 그냥 컴퓨터를 막 꺼버린 경우에 이런 에러가 발생하는거 아닌가 싶습니다.)

이번 포스팅에서는 도커를 사용할 때 "포트가 이미 할당되어 있어서 연결에 실패했습니다 (port is already allocated)" 에러가 발생했을 때 대처 방법을 소개하겠습니다.
(1) 5432 포트가 사용 중인지 여부 확인하기 : sudo lsof -i :5432
port 번호는 docker run 할 때 할당했던 port 번호를 입력해주세요. 저는 5432 로 했었기에 5432 입력했습니다.

postgresql 두 개가 5432 port 를 점유하고 있네요.
(2) 이미 할당된 port 죽이기 : sudo kill -15 93
ihongdon-ui-MacBook-Pro:~ ihongdon$ ihongdon-ui-MacBook-Pro:~ ihongdon$ sudo kill -15 93
ihongdon-ui-MacBook-Pro:~ ihongdon$

죽여, 살려 하니깐 좀 말이 과격한데요, ^^; 원치 않게 자리를 점하고 있던 좀비 port를 죽였습니다(kill).
(1)번에서 했던 방법으로 5432 번호에 할당된 port를 조회해 볼까요? 아무것도 없네요.
ihongdon-ui-MacBook-Pro:~ ihongdon$ sudo lsof -i :5432

(3) 도커 컨터이너 시작하기 : docker start container_name

다시 잘 실행되네요. ^^
많은 도움이 되었기를 바랍니다.
