bigbluebutton/bbb-playback-proxyBigBlueButton会记录会话期间生成的所有事件和媒体数据用于后续回放。其录制流程包含捕获、归档、验证、处理、发布和回放六个阶段,最终生成的媒体文件默认存储在BigBlueButton服务器的文件系统中,由服务器内置的Nginx作为静态内容提供访问。
但在部分场景下(如本地文件系统存储容量不足、集群环境中多服务器录制内容需聚合),需要独立的服务来存储和提供录制内容。bbb-playback-proxy Docker镜像即为此设计,作为专注于提供录制内容访问的代理服务。
基于Linux系统(alpine或amazonlinux)构建,内置Nginx,包含与BigBlueButton服务器完全一致的Nginx配置文件、媒体播放器及目录结构,可无缝对接录制内容存储。
仅对外暴露80端口,用于提供HTTP服务。
bashdocker run -d -p 80:80 -v /mnt/scalelite-recordings/var/bigbluebutton/:/var/bigbluebutton/ bigbluebutton/bbb-playback-proxy:bionic-23-dev-alpine3.11
参数说明:
-v /mnt/scalelite-recordings/var/bigbluebutton/:/var/bigbluebutton/:将本地录制内容目录挂载至容器内对应路径,需确保目录结构与BigBlueButton服务器一致yamlversion: '3' services: frontend-proxy: image: nginx:latest container_name: frontend-proxy restart: unless-stopped volumes: - ./proxy/log/nginx/:/var/log/nginx - ./proxy/nginx/sites.template.${DOCKER_PROXY_NGINX_TEMPLATE:-scalelite-proxy}:/etc/nginx/sites.template - ./data/certbot/conf/:/etc/letsencrypt - ./data/certbot/www/:/var/www/certbot ports: - "80:80" - "443:443" environment: - NGINX_HOSTNAME=${URL_HOST:-xlab.blindside-dev.com} depends_on: - certbot - recording-proxy command: /bin/bash -c "envsubst '$$NGINX_HOSTNAME' < /etc/nginx/sites.template > /etc/nginx/conf.d/default.conf && exec nginx -g 'daemon off;'" recording-proxy: image: bigbluebutton/bbb-playback-proxy:bionic-23-dev-alpine3.11 container_name: recording-proxy restart: unless-stopped volumes: - /mnt/recordings/var/bigbluebutton/published:/var/bigbluebutton/published certbot: image: certbot/certbot container_name: certbot volumes: - ./log/certbot:/var/log/letsencrypt - ./data/certbot/conf:/etc/letsencrypt - ./data/certbot/www:/var/www/certbot entrypoint: "/bin/sh -c 'trap exit TERM; while :; do certbot renew; sleep 12h & wait $${!}; done;'"
-v参数将存储录制内容的目录(如/mnt/scalelite-recordings/var/bigbluebutton/)挂载至容器内的/var/bigbluebutton/路径,确保目录结构与BigBlueButton服务器一致(包含published等子目录)。-p 80:80将容器80端口映射至主机,提供HTTP访问。
