Docker Compose Example

Docker Compose와 버전별 특징 : NHN Cloud Meetup

도커는 이제 대부분의 개발자 노트북이나 PC에 하나씩은 설치되어있는 필수품이 되어가는데요 편하고 유용한 도커를 좀 더 유익하고 편하게 사용할 수 있는 도구인 Docker Compose에 대해서 알기 쉽게 정리하는 시간을 가졌습니다. Compose를 처음 접하시는 분도 가볍게 사용이 가능하도록 쉽게 풀어보았습니다. 다들 Compose와 조금 더 친해지러 가볼까요?

Some syntax particularity about this may have important behaviours. There is some little samples about redirections, STDERR, STDOUT, and arguments ordering. Symbol > means redirection. > means send to as a whole completed file, overwriting target if exist (see noclobber bash feature at #3 later).

Default owner/permissions of created files via VSFTPD

In case you are wondering where to set your umask, it can be set in the vsftpd config file (/etc/vsftpd.conf) as anon_umask for anonymous access and local_umask for users. For the mask to work properly (even without anonymous access) it seems necessary to set anon_upload_enable=YES and anon_mkdir_write_enable=YES.

Adminer vs phpMyAdmin 비교

PhpMyAdmin을 밀어낼 강력한 관리툴 Adminer

웹 기반으로 한 데이터베이스 관리라면 PhpMyAdmin 을 모르는 분을 없을 거라고 생각합니다. 굉장히 간편하고 어디에서든지 데이터 베이스를 관리할 수 있다는 점이 가장 큰 장점입니다. 하지만 최근들어 워낙 phpMyAdmin이 유명해 지다 보니 setup 폴더를 통해 해킹을 하는 사례도 늘고 있다고 합니다. 유명한만큼 표적이 되는 것이지요. 편리하고 다양한 기능이 많은 phpMyAdmin의 경우에는 생각보다 설치하는 용량이 꽤 됩니다.
