在 Docker 中运行 bluenviron/mediamtx:1.15.1 时，如何修复 “too many open files” 错误？

docker命令： .

docker run -d \
  --name mediamtx \
  -e MTX_RTSPTRANSPORTS=tcp \
  -e MTX_WEBRTCADDITIONALHOSTS=172.16.11.61 \
  -e RTSP_RTSPADDRESS=0.0.0.0:8554 \
  bluenviron/mediamtx:1.15.1

乌班图下报错如下： .

(base) root@dsy-System-Product-Name:~/k8syaml/moonfdd# docker rm mediamtx
mediamtx
(base) root@dsy-System-Product-Name:~/k8syaml/moonfdd# docker run -d \

  -e RTSP_RTSPADDRESS=0.0.0.0:8554 \

解决方案见 https://github.com/bluenviron/mediamtx/issues/3452#issuecomment-2160553182：

输入如下命令，重启docker，问题解决： .

echo "fs.inotify.max_user_instances=1280" | sudo tee -a /etc/sysctl.conf
echo "fs.inotify.max_user_watches=655360" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
