Janus Gateway를 이용해서 미러링

 

1. Docker build

• 베이스 코드: https://github.com/baiyongzhen/webrtc-janus
• 여기서 dockerfile을 아래와 같이 수정

2. docker-compose

• 단일 서버에서 여러개의 컨테이너를 하나의 서비스로 정의해 컨테이너의 묶음으로 관리할 수 있도록 설정
• /webrtc-janus/docker/janus-gateway/v1.1.0로 이동 후
• $ docker-compose up -d
• 컨테이너가 정상적으로 실행 중인지 확인
  • $ docker ps

 

* web container가 계속 restarting되는 문제 발생

• 로그를 보니(docker logs $container_id) 다음과 같이 나옴

/docker-entrypoint.sh: Configuration complete; ready for start up
2024/03/20 01:19:37 [emerg] 1#1: unknown directive "ssl" in /etc/nginx/conf.d/default.conf:12
nginx: [emerg] unknown directive "ssl" in /etc/nginx/conf.d/default.conf:12

• 원인: ssl 지시어를 인식하지 못 하는 문제
• 해결책: nginx.conf를 다음과 같이 수정
  • listen 뒤에 ssl 붙이기
    • "listen 443" -> "listen 443 ssl"
  • "ssl on" 부분 모두 주석 처리 -> #    ssl on;

}

• 이제 다시 확인해보면 status가 up으로 바뀐 것을 확인할 수 있다.

• 컨테이너가 정상적으로 떴는지 확인
  • "https://127.0.0.1/" 접속했을 때 아래의 화면이 나오면 정상적으로 실행된 것.
  • 여기서 Demos > Echo Test를 했을 때, 카메라 화면이 잘 미러링 돼야 한다.
