Awesome.

You not only solved your problem but learned a heap along the way.

I love searxng too btw. It’s the best way to search for the time being.

I’ve never used portainer sorry.

If you see the published port for a very short time then something might be crashing when it tries to start.

docker logs searxng from cli might be revealing

edit: I do have a searxng container and my compose.yml is very similar to yours. I guess we both copied the example. The only difference I can see is that you still have the env variables for UWSGI_WORKERS and UWSGI_THREADS. I just set both of those to 4 instead of using the SEARXNG_ env vars
