WSL에서 Spring Cloug Config Server를 Docker 배포 중 Git 내용을 못 가지고 오는 문제

January 28th, 2022

커피 중독자되는 중…

WSL Ubuntu 20.04 버전에서 Spring Cloud Config Server를 Docker로 구축하던 중 Git 내용을 못 가지고 오는 에러

최근에 듣게 된 inflear 강의가 하나 있다.

바로 이도원 강사님의 Spring Cloud로 개발하는 마이크로서비스 애플리케이션(MSA)이다.

Spring MSA 관련해서 많은 내용을 다루고 실습도 알차서 매우 좋은 강의이다.

마지막 챕터를 향해 달려가던 중 문제가 생겼다. 로컬에서 잘 작동되던 config-server가 제대로 작동하지 않았다.

어떤 에러인지는 내가 직접 inflear에 질문을 하고 직접 답변을 한 링크를 달겠다.

일주일동안 이 에러에 시달렸던 것 같다. 아무리 구글링을 해도 찾을 수가 없었고 결국 한줄한줄 읽어보며 뭐가 문제인지 찾아봤던 것 같다.

읽다가 위 내용에 신경이 좀 가게됐다. 일단 컨테이너 내부적으로 git clone 명령을 해서 해당 리포지토리를 가지고 온다음 거기서 원하는 리소스를 가져오는 방법인 것 같았다.

그렇다면 어떤 디렉토리 아래 폴더에 clone를 하고 가져오는지 찾는 게 중요했다.

어디에서 clone를 하는지 찾기 위해서 도커로 배포 안 하고 단순히 WSL Ubuntu 환경에서 jar 파일을 실행시키고 로그를 살펴보았다. 신기하게 이때는 제대로 작동하고 원하는 리소를 가져온다.

위 로그를 통해서 내가 만약 Dockerfile를 통해 컨테이너를 실행하게 되면 config-server는 컨테이너의 /tmp/config-repo-(랜덤 숫자들) 폴더 안에서 리소스를 가져온다는 것이다. ecommerce.yml과 application.yml 파일의 내용이 내가 원하는 리소스 내용이다.

정리

정리하면 내가 Dockerfile를 통해 이미지를 만들고 run하게 되면 config-server가 내부적으로 /tmp/config-repo-(랜덤숫자들) 디렉토리 안에서 git clone url를 하게 되는 것이다. 그리고 그렇게 clone한 리소스를 우리가 특정 url로 접근하게 되면 보여주는 것이다.

확인을 위해 다시 도커 이미지를 실행시키고 sudo docker exec -it [컨테이너 ID] bash 명령을 통해 터미널로 들어가보았다.

역시 예상했던 대로 /tmp/config-repo 폴더가 생성이 되어 있었고 안에는 아무 내용이 없었다. 그리고 git clone [내 리소스가 있는 url] 명령을 치자 clone이 되지 않았다. 물론 그전에 이 명령어들을 실행하고 다운받는 것이 필요하다

apt-get update -y; \
apt-get upgrade -y; \
apt-get install git -y;

git clone만 된다면 문제는 해결될 것이다. 구글링을 하다가 나와 비슷한 문제가 발생한 사람의 질문 중 답변을 확인해보니 ping github.com의 결과가 제대로 나오는지 보라는 것이었다.

역시나 제대로 작동하지 않았다. 그렇다면 WSL 안에 컨테이너가 외부 네트워크랑 통신을 못하고 있다고 가정을 하게 되었다.

그리고 여러 자료를 찾다가 해결 방안을 2가지 찾았다.

(해결 1) /etc/resolv.conf 파일 수정하기

컨테이너 안으로 이전에 했던 명령어 exec -it로 터미널에 들어가고 /etc/resolv.conf 파일을 열게되면 아래와 같은 사진의 내용이 보인다.

이 내용을 아래와 같이 수정하는 것이다.

nameserver 127.0.0.11
nameserver 8.8.8.8
nameserver 8.8.4.4
options edns0

그리고 /tmp/config-repo-(랜덤 숫자들) 폴더 아래 git clone [원하는 리소스가 있는 리포지토리 url]를 하면 제대로 접근이 된다.

하지만 이 방법은 일일이 컨테이너를 없애고 만들때마다 해줘야 하며 이는 매우 불편하다.

(해결 2) /etc/default 디렉터리 아래 docker 파일 수정하기

기본 WSL Ubuntu 터미널에서 docker를 다운받았다면 /etc/default 디렉터리 안에 docker라는 파일이 있다 이를 아래와 같이 수정한다.

# Docker Upstart and SysVinit configuration file

#
# THIS FILE DOES NOT APPLY TO SYSTEMD
#
#   Please see the documentation for "systemd drop-ins":
#   https://docs.docker.com/engine/admin/systemd/
#

# Customize location of Docker binary (especially for development testing).
#DOCKERD="/usr/local/bin/dockerd"

# Use DOCKER_OPTS to modify the daemon startup options.
DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"

# If you need Docker to use an HTTP proxy, it can also be specified here.
#export http_proxy="http://127.0.0.1:3128/"

# This is also a handy place to tweak where Docker's temporary files go.
#export DOCKER_TMPDIR="/mnt/bigdrive/docker-tmp"

이렇게 하고 config-server를 배포하게 되면 정상적으로 리소스를 가져올 수 있고 해결 1 방안보다 더 좋다.
