Container 공부를하며 Docker 플랫폼을 접한지 약 2주가 되었다. 일전에 사놓은 Raspberry Pi 3 B+가 놀고 있어 Dokuwiki를 Docker를 통해 구축하기로 했다. Dokuwiki의 선택은 문서가 RDBMS가 아닌 txt 파일로 저장되며, Raspberry Pi의 성능을 생각해보면 DB로 인한 부하를 주는 것보다는 훨씬 좋겠다고 생각했다. 이런 생각은 Raspberry Pi에는 SSD 128(Samsung 830)이 장착되어있기 떄문이다.
구성 환경
- Raspberry Pi 3 B+
- Raspbian Stretch Lite
- Raspberry Pi에 Docker 설치

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run
containers which can be used to obtain root privileges on the
docker host.
Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
for more information.
