Raspberry PI 설정
- Raspbian Image Download : https://downloads.raspberrypi.org/raspbian_lite_latest
- 압축 해제 후 인스톨 가이드에 따라 SD카드 이미지에 복원
- Raspberry PI에 SD카드 삽입 후 모니터 연결 후 전원 연결 (키보드도 미리 연결)
- SD카드에 맞게 자동으로 리사이즈 과정 진행 됨.
- 리부팅 후 login 프롬프트가 뜨면 로그인 ( pi / raspberry )
- sudo raspi-config 실행
- TUI 에서 필요한 항목 셋팅 (언어, 타임존 등등)
- 필요한 소프트웨어 설치
- docker 설치 - sudo apt install docker.io
- python3 pip 설치 - sudo apt install python3-pip
- docker-compose 설치 - sudo pip3 install docker-compose (4.7일 기준 1.25.4버전이 설치됨)
- open jdk8 설치 - sudo apt install openjdk-8-jdk
- GPIO 커맨드툴 설치
