[mod] container: replace uWSGI with Granian (#4820)

* [mod] container: replace uWSGI with Granian

The configuration in Granian is handled with ENVs, much more convenient and practical for updating. The settings have been tested for over two months in a production instance, being usable on small to somewhat large instances without having to modify anything.

It also removes the patch functions and ENVs abstraction from the entrypoint, this makes it possible to run the container with immutable configuration.

In some setups, It may be desired to have the volumes/files under a specific uid/gid (other than searxng:searxng), if the entrypoint has root permissions it will chown automatically on every start, which may not be desired. Explicitly setting the new ENV `FORCE_OWNERSHIP=false` will prevent ownership from being modified.

No manual migration is necessary **unless** the user has changed the default uWSGI configuration or has a very specific setup.

+.. _Container prerequisites:
 
-----
+Prerequisites
+-------------
 
+You need a working Docker or Podman installation on your system.  Choose the
+option that works best for your environment:
 
-Get Docker
-==========
+- `Docker <https://docs.docker.com/get-docker/>`_ (recommended for most users)
+- `Podman <https://podman.io/docs/installation>`_
 
-If you plan to build and maintain a docker image by yourself, make sure you have
-`Docker installed <https://docs.docker.com/get-docker/>`_. On Linux don't
-forget to add your user to the docker group (log out and log back in so that
-your group membership is re-evaluated):
+In the case of Docker, you need to add the user running the container to the
+``docker`` group and restart the session:
 
 .. code:: sh
 
-   $ sudo usermod -a -G docker $USER
-
+   $ sudo usermod -aG docker $USER
 
-searxng/searxng
-===============
+In the case of Podman, no additional steps are generally required, but there
+are some considerations when running `Podman rootless containers`_.
 
-.. sidebar:: ``docker run``
+.. _Container pulling images:
 
-   - `-\-rm  <https://docs.docker.com/engine/reference/run/#clean-up---rm>`__
-     automatically clean up when container exits
-   - `-d <https://docs.docker.com/engine/reference/run/#detached--d>`__ start
-     detached container
-   - `-v <https://docs.docker.com/engine/reference/run/#volume-shared-filesystems>`__
-     mount volume ``HOST:CONTAINER``
+Pulling images
+--------------
 
-The docker image is based on :origin:`Dockerfile` and available from
-`searxng/searxng @dockerhub`_.  Using the docker image is quite easy, for
-instance you can pull the `searxng/searxng @dockerhub`_ image and deploy a local
-instance using `docker run <https://docs.docker.com/engine/reference/run/>`_:
+.. note::
 
-.. code:: sh
+   DockerHub now applies rate limits to unauthenticated image pulls.  If you
+   are affected by this, you can use the `GHCR mirror`_ instead.
 
-   $ mkdir my-instance
-   $ cd my-instance
-   $ export PORT=8080
-   $ docker pull searxng/searxng
-   $ docker run --rm \
-                -d -p ${PORT}:8080 \
-                -v "${PWD}/searxng:/etc/searxng" \
-                -e "BASE_URL=http://localhost:$PORT/" \
-                -e "INSTANCE_NAME=my-instance" \
-                searxng/searxng
-   2f998.... # container's ID
+The official images are mirrored at:
 
-The environment variables UWSGI_WORKERS and UWSGI_THREADS overwrite the default
-number of UWSGI processes and UWSGI threads specified in `/etc/searxng/uwsgi.ini`.
+- `DockerHub mirror`_
+- `GHCR mirror`_ (GitHub Container Registry)
 
-Open your WEB browser and visit the URL:
+Pull the latest image:
 
 .. code:: sh
 
-   $ xdg-open "http://localhost:$PORT"
+   $ docker pull docker.io/searxng/searxng:latest
 
-Inside ``${PWD}/searxng``, you will find ``settings.yml`` and ``uwsgi.ini``.  You
-can modify these files according to your needs and restart the Docker image.
+\.\. or if you want to lock in to a specific version:
 
 .. code:: sh
 
-   $ docker container restart 2f998
+   $ docker pull docker.io/searxng/searxng:2025.6.3-b73ac81
 
-Use command ``container ls`` to list running containers, add flag `-a
-<https://docs.docker.com/engine/reference/commandline/container_ls>`__ to list
-exited containers also.  With ``container stop`` a running container can be
-stopped.  To get rid of a container use ``container rm``:
+.. _Container instancing:
+
+Instancing
+==========
+
+This section is intended for advanced users who need custom deployments.  We
+recommend using `Docker compose`_, which provides a preconfigured environment
+with sensible defaults.
+
+Basic container instancing example:
 
 .. code:: sh
 
-   $ docker container ls
-   CONTAINER ID   IMAGE             COMMAND                  CREATED         ...
-   2f998d725993   searxng/searxng   "/sbin/tini -- /usr/…"   7 minutes ago   ...
+   # Create directories for configuration and persistent data
+   $ mkdir -p ./searxng/config/ ./searxng/data/
+   $ cd ./searxng/
 
-   $ docker container stop 2f998
-   $ docker container rm 2f998
+   # Run the container
+   $ docker run --name searxng --replace -d \
+       -p 8888:8080 \
+       -v "./config/:/etc/searxng/" \
+       -v "./data/:/var/cache/searxng/" \
+       docker.io/searxng/searxng:latest
 
-.. sidebar:: Warning
+This will start SearXNG in the background, accessible at http://localhost:8888
 
-   This might remove all docker items, not only those from SearXNG.
+.. _Container management:
 
-If you won't use docker anymore and want to get rid of all containers & images
-use the following *prune* command:
+Management
+----------
 
-.. code:: sh
+List running containers:
 
-   $ docker stop $(docker ps -aq)       # stop all containers
-   $ docker system prune                # make some housekeeping
-   $ docker rmi -f $(docker images -q)  # drop all images
+.. code:: sh
 
+   $ docker container list
+   CONTAINER ID  IMAGE  ...  CREATED        PORTS                   NAMES
+   37f6487c8703  ...    ...  3 minutes ago  0.0.0.0:8888->8080/tcp  searxng
 
-shell inside container
-----------------------
+Access the container shell (troubleshooting):
 
-.. sidebar:: Bashism

+   $ docker container exec -it --user root searxng /bin/sh -l
+   37f6487c8703:/usr/local/searxng#
 
-To open a shell inside the container:
+Stop and remove the container:
 
 .. code:: sh
 
-   $ docker exec -it 2f998 sh
+   $ docker container stop searxng
+   $ docker container rm searxng
 
+.. _Container volumes:

-It's also possible to build SearXNG from the embedded :origin:`Dockerfile`::
+Two volumes are exposed that should be mounted to preserve its contents:

+Environment variables
+=====================
 
-Command line
-============
+The following environment variables can be configured:
+
+- ``$SEARXNG_*``: Controls the SearXNG configuration options, look out for
+  environment ``$SEARXNG_*`` in :ref:`settings server` and :ref:`settings
+  general`.
+- ``$GRANIAN_*``: Controls the :ref:`Granian server options <Granian configuration>`.
+- ``$FORCE_OWNERSHIP``: Ensures mounted volumes/files are owned by the
+  ``searxng:searxng`` user (default: ``true``)
+
+Container internal paths (don't modify unless you know what you're doing):
 
-.. sidebar:: docker run
+- ``$CONFIG_PATH``: Path to the SearXNG configuration directory (default: ``/etc/searxng``)
+- ``$SEARXNG_SETTINGS_PATH``: Path to the SearXNG settings file (default: ``$CONFIG_PATH/settings.yml``)
+- ``$DATA_PATH``: Path to the SearXNG data directory (default: ``/var/cache/searxng``)
 
-   Use flags ``-it`` for `interactive processes
-   <https://docs.docker.com/engine/reference/run/#foreground>`__.
+.. _Container custom images:
 
-In the :origin:`Dockerfile` the ENTRYPOINT_ is defined as
-:origin:`container/entrypoint.sh`
+Custom images
+=============
+
+To build your own SearXNG container image from source (please note, custom
+container images are not officially supported):

+Installation
+============

+Configuration
+=============
+
+.. note::
+
+   It's not advised to modify the amount of workers, expect increased resource
+   usage and potential issues with :ref:`botdetection`.
+
+Granian can be configured via option parameters and environment variables
+(``$GRANIAN_*``).
+
+We provide sane defaults that should fit most use cases, however if you feel
+you should change something, Granian documents all available parameters in the
+`Options`_ section.
