|
|
.. tip::
|
|
|
|
If you intend to create a public instance using Docker, use our well
|
|
maintained searxng-docker_ image which includes
|
|
|
|
- :ref:`protection <searxng filtron>` `[filtron]`_,
|
|
- a :ref:`result proxy <searxng morty>` `[morty]`_ and
|
|
- a HTTPS reverse proxy `[caddy]`_.
|
|
|
|
Make sure you have `installed Docker <https://docs.docker.com/get-docker/>`_ and
|
|
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):
|
|
|
|
.. code:: sh
|
|
|
|
$ sudo usermod -a -G docker $USER
|
|
|
|
|
|
searxng/searxng
|
|
===============
|
|
|
|
.. sidebar:: ``docker run``
|
|
|
|
- `-\-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``
|
|
|
|
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/>`_:
|
|
|
|
.. code:: sh
|
|
|
|
$ 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
|
|
|
|
Open your WEB browser and visit the URL:
|
|
|
|
.. code:: sh
|
|
|
|
$ xdg-open "http://localhost:$PORT"
|
|
|
|
Inside ``${PWD}/searxng``, you will find ``settings.yml`` and ``uwsgi.ini``. You
|
|
can modify these files according to your needs and restart the Docker image.
|
|
|
|
.. code:: sh
|
|
|
|
$ docker container restart 2f998
|
|
|
|
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
|
|
stoped. To get rid of a container use ``container rm``:
|
|
|
|
.. code:: sh
|
|
|
|
$ docker container ls
|
|
CONTAINER ID IMAGE COMMAND CREATED ...
|
|

|
|
|
|
$ docker container stop 2f998
|
|
$ docker container rm 2f998
|
|
|
|
.. sidebar:: Warning
|
|
|
|
This might remove all docker items, not only those from SearXNG.
|
|
|
|
If you won't use docker anymore and want to get rid of all conatiners & images
|
|
use the following *prune* command:
|
|
|
|
.. code:: sh
|
|
|
|
$ docker stop $(docker ps -aq) # stop all containers
|
|
$ docker system prune # make some housekeeping
|
|
$ docker rmi -f $(docker images -q) # drop all images
|
|
|
|
|
|
shell inside container

|
|
|
|
Like in many other distributions, Alpine's `/bin/sh
|
|
<https://wiki.ubuntu.com/DashAsBinSh>`__ is :man:`dash`. Dash is meant to be
|
|
`POSIX-compliant <https://pubs.opengroup.org/onlinepubs/9699919799>`__.
|
|
Compared to debian, in the Alpine image :man:`bash` is not installed. The
|
|
:origin:`dockerfiles/docker-entrypoint.sh` script is checked *against dash*
|
|
(``make tests.shell``).
|
|
|
|
To open a shell inside the container:
|
|
|
|
.. code:: sh
|
|
|
|
$ docker exec -it 2f998 sh
|
|
|
|
|
|
Build the image
|
|
===============
|
|
|
|
It's also possible to build SearXNG from the embedded :origin:`Dockerfile`::
|
|
|
|
$ git clone https://github.com/searxng/searxng.git
|
|
$ cd searxng
|
|
$ make docker.build
|
|
...

Command line
|
|
============
|
|
|
|
.. sidebar:: docker run
|
|
|
|
Use flags ``-it`` for `interactive processes
|
|
<https://docs.docker.com/engine/reference/run/#foreground>`__.
|
|
|
|
In the :origin:`Dockerfile` the ENTRYPOINT_ is defined as
|
|
:origin:`dockerfiles/docker-entrypoint.sh`
|
|
|
|
.. code:: sh
|
|
|
|
docker run --rm -it searxng/searxng -h
|
|
|
|
.. program-output:: ../dockerfiles/docker-entrypoint.sh -h
