2년간 운영하던 서버의 디스크 160GB 까지 가득 차는 문제가 발생했다.
문제의 원인으로는 2가지가 있다.
1. Docker Registry 서버를 Private 으로 운영했기 때문에 Docker Image 가 너무 많았다.
2. SMTP 서버를 구축해 놓았기 때문에 Log 가 너무 많았다.
그간 디스크가 90프로 정도 찰 때마다 불필요한 이미지를 정리하고 logrotate 을 통해 로그를 관리하였고 마지막 영혼을 불태워 Docker Registry 서버를 가성비 좋은 S3 로 이전하려 했으나 디스크가 기다려주지 않아 서버를 확장하게 되었다.
아래는 마지막 순간까지 살아 있던 내 서비스들이다.

계획
- 서버는 총 2대로 확장할 생각이며
- Docker Swrm 을 추가할 계획이다.
- Docker Registry 는 당연히 Harbor + S3 을 사용해 Private 하게 갈 생각이다.
- Database 는 Read-write, Read-only 를 지원할 것이며 중복되는 Database 는 실행하지 않 것이다.
- Docker Image 을 다시 빌드하고
- 대부분 프로젝트는 단일 컨테이너 이기 때문에 Image 에 따라 1개씩 디폴로이 할 수 있도록 Script 을 추가할 것이고 MSA 프로젝트의 경우 docker compose 으로 일부 작성 되어 있기 때문에 docker stack 으로 관리할 것이다.
서버를 한대씩 추가할 때 마다 아래 스크립트르 통해 기본적으로 필요한 것들을 추가해 나갈 생각이지만
앞으로 2년간은 2대면 충분할 것 같다.

This is the Z Shell configuration function for new users,
zsh-newuser-install.
You are seeing this message because you have no zsh startup files
(the files .zshenv, .zprofile, .zshrc, .zlogin in the directory
~). This function can help you with a few settings that should
make your use of the shell easier.
You can:
(q) Quit and do nothing. The function will be run again next time.
(0) Exit, creating the file ~/.zshrc containing just a comment.
That will prevent this function being run again.
(1) Continue to the main menu.
(2) Populate your ~/.zshrc with the configuration recommended
by the system administrator and exit (you will need to edit
the file by hand, if so desired).
