Yep Probably you need to change ownership and/or permissions of the files outside of docker.

I dont want to give the wrong suggestion from memory so hopefully thats enough info to get you going in the direction of a fix. Basically see what user id owns the files inside of docker, make it the same uid outside of docker in the folder you are bind mounting.

try opening a shell with ’ docker exec -it searxng sh" and see if you can cat the file from inside docker, if yes then I’m not sure of a solution ,if no then the problem is with permissions on your filesystem outside of docker where you have " - ./data/searxng:/etc/searxng" You need to go to ./data/searxng and correct the permissions so they can be read inside the docker.

open(“/etc/searxng/uwsgi.ini”): Permission denied [core/io.c line 525]

I think here is your problem. Make sure that file exists and is readable from inside of the docker.
