In simple terms, because the /data directory is a mounted host machine's disk directory, after modifying the /data/record soft link to another directory, it cannot be accessed in the docker container.

If docker is started directly, you can mount the /data and /data/record directories, for example:

docker run -v $HOME/data:/data -v /tmp/record:/data/record ......

If it is installed via BaoTa, aaPanel, image, or script, you need to modify the /usr/local/srs-stack/mgmt/bootstrap startup script, which is not easy.

Need to modify the text prompt for the recording, you cannot directly create a symbolic link to the /data/record directory.

Since you can't directly modify /data/record in Docker, a simpler way is to directly modify the /data directory. The text prompt has already been updated.

Of course, if you're using Docker, you can also use the -v /tmp/record:/data/record command to mount the directory. That works too.
