-Developing in Linux Containers
-==============================
-
-.. _LXC: https://linuxcontainers.org/lxc/introduction/
-
-In this article we will show, how you can make use of Linux Containers (LXC_) in
-*distributed and heterogeneous development cycles* (TL;DR; jump to the
-:ref:`lxcdev summary`).
-
-.. sidebar:: Audience
-
-   This blog post is written for experienced admins and developers.  Readers
-   should have a serious meaning about the terms: *distributed*, *merge* and
-   *linux container*.
-
-   **hint**
-
-   If you have issues with the internet connectivity of your containers read
-   section :ref:`internet connectivity docker`.

-Motivation
-==========
-
-Most often in our development cycle, we edit the sources and run some test
-and/or builds by using ``make`` :ref:`[ref] <makefile>` before we commit.  This
-cycle is simple and perfect but might fail in some aspects we should not
-overlook.
-
-  **The environment in which we run all our development processes matters!**
-
-The :ref:`makefile` and the :ref:`make install` encapsulate a lot for us, but
-these tools do not have access to all prerequisites.  For example, there may
-have dependencies on packages that are installed on developer's desktop, but
-usually are not preinstalled on a server or client system.  Another example is;
-settings have been made to the software on developer's desktop that would never
-be set on a *production* system.
-
-  **Linux Containers are isolate environments**, we use them to not mix up all
-  the prerequisites from various projects on developer's desktop.
-
-The scripts from :ref:`searx_utils` can divide in those to install and maintain
-software
-
-- :ref:`searxng.sh`
-
-and the script
-
-- :ref:`lxc.sh`
-
-with we can scale our installation, maintenance or even development tasks over a
-stack of isolated containers / what we call the:
-
-- :ref:`searxng lxc suite`

-
-Gentlemen, start your engines!
-==============================
-
-.. _LXD: https://linuxcontainers.org/lxd/introduction/
-.. _archlinux: https://www.archlinux.org/
-
-Before you can start with containers, you need to install and initiate LXD_
-once:
-
-.. tabs::
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ snap install lxd
-        $ lxd init --auto
-
-And you need to clone from origin or if you have your own fork, clone from your
-fork:
-
-.. tabs::
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ cd ~/Downloads
-        $ git clone https://github.com/searxng/searxng.git searxng
-        $ cd searxng
-
-.. sidebar:: The ``searxng-archlinux`` container
-
-   is the base of all our exercises here.
-
-The :ref:`lxc-searxng.env` consists of several images, see ``export
-LXC_SUITE=(...`` near by :origin:`utils/lxc-searxng.env#L19`.
-For this blog post we exercise on a archlinux_ image.  The container of this
-image is named ``searxng-archlinux``.
-
-Lets build the container, but be sure that this container does not already
-exists, so first lets remove possible old one:
-
-.. tabs::
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh remove searxng-archlinux
-        $ sudo -H ./utils/lxc.sh build searxng-archlinux
-
-
-.. sidebar::  further read
-
-   - :ref:`lxc.sh install suite`
-   - :ref:`installation nginx`
-
-To install the complete :ref:`SearXNG suite <searxng lxc suite>` and the HTTP
-proxy :ref:`installation nginx` into the archlinux container run:
-
-.. tabs::
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh install suite searxng-archlinux
-        $ sudo -H ./utils/lxc.sh cmd -- FORCE_TIMEOUT=0 ./utils/searxng.sh install nginx
-        $ sudo ./utils/lxc.sh show suite | grep SEARXNG_URL
-        ...
-        [searxng-archlinux]    SEARXNG_URL          : http://n.n.n.140/searxng
-
-.. sidebar:: Fully functional SearXNG suite
-
-   From here on you have a fully functional SearXNG suite (including a
-   :ref:`valkey db`).
-
-In such a SearXNG suite admins can maintain and access the debug log of the
-services quite easy.
-
-In the example above the SearXNG instance in the container is wrapped to
-``http://n.n.n.140/searxng`` to the HOST system.  Note, on your HOST system, the
-IP of your ``searxng-archlinux`` container is different to this example.  To
-test the instance in the container from outside of the container, in your WEB
-browser on your desktop just open the URL reported in your installation
-
-.. _working in containers:
-
-In containers, work as usual
-============================
-
-Usually you open a root-bash using ``sudo -H bash``.  In case of LXC containers
-open the root-bash in the container is done by the ``./utils/lxc.sh cmd
-searxng-archlinux`` command:
-
-.. tabs::
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux bash
-        INFO:  [searxng-archlinux] bash
-        [root@searxng-archlinux SearXNG]$
-
-The prompt ``[root@searxng-archlinux ...]`` signals, that you are the root user
-in the container (GUEST).  To debug the running SearXNG instance use:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ ./utils/searxng.sh instance inspect
-        ...
-        use [CTRL-C] to stop monitoring the log
-        ...
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux ./utils/searxng.sh instance inspect
-        ...
-        use [CTRL-C] to stop monitoring the log
-        ...
-
-
-Back in the browser on your desktop open the service http://n.n.n.140/searxng
-and run your application tests while the debug log is shown in the terminal from
-above.  You can stop monitoring using ``CTRL-C``, this also disables the *"debug
-option"* in SearXNG's settings file and restarts the SearXNG uwsgi application.
-
-Another point we have to notice is that the service :ref:`SearXNG <searxng.sh>`
-runs under dedicated system user account with the same name (compare
-:ref:`create searxng user`).  To get a login shell from these accounts, simply
-call:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ ./utils/searxng.sh instance cmd bash -l
-        (searx-pyenv) [searxng@searxng-archlinux ~]$ pwd
-        /usr/local/searxng
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux ./utils/searxng.sh instance cmd bash -l
-        INFO:  [searxng-archlinux] ./utils/searxng.sh instance cmd bash -l
-        (searx-pyenv) [searxng@searxng-archlinux ~]$ pwd
-        /usr/local/searxng
-
-The prompt ``[searxng@searxng-archlinux]`` signals that you are logged in as system
-user ``searxng`` in the ``searxng-archlinux`` container and the python *virtualenv*
-``(searxng-pyenv)`` environment is activated.
-
-
-Wrap production into developer suite
-====================================
-
-In this section we will see how to change the *"Fully functional SearXNG suite"*
-from a LXC container (which is quite ready for production) into a developer
-suite.  For this, we have to keep an eye on the :ref:`installation basic`:
-
-- SearXNG setup in: ``/etc/searxng/settings.yml``
-- SearXNG user's home: ``/usr/local/searxng``
-- virtualenv in: ``/usr/local/searxng/searxng-pyenv``
-- SearXNG software in: ``/usr/local/searxng/searxng-src``
-
-With the use of the :ref:`searxng.sh` the SearXNG service was installed as
-:ref:`uWSGI application <searxng uwsgi>`.  To maintain this service, we can use
-``systemctl`` (compare :ref:`uWSGI maintenance`).
-
-.. tabs::
-
-  .. group-tab:: uwsgi@searxng
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux systemctl stop uwsgi@searxng
-
-With the command above, we stopped the SearXNG uWSGI-App in the archlinux
-container.
-
-The uWSGI-App for the archlinux distros is configured in
-:origin:`utils/templates/etc/uwsgi/apps-archlinux/searxng.ini`, from where at
-least you should attend the settings of ``uid``, ``chdir``, ``env`` and
-``http``::
-
-  env = SEARXNG_SETTINGS_PATH=/etc/searxng/settings.yml
-  http = 127.0.0.1:8888
-
-  chdir = /usr/local/searxng/searxng-src/searx
-  virtualenv = /usr/local/searxng/searxng-pyenv
-  pythonpath = /usr/local/searxng/searxng-src
-
-If you have read the :ref:`Good to know` you remember, that each container
-shares the root folder of the repository and the command ``utils/lxc.sh cmd``
-handles relative path names **transparent**.
-
-To wrap the SearXNG installation in the container into a developer one, we
-simple have to create a symlink to the **transparent** repository from the
-desktop.  Now lets replace the repository at ``searxng-src`` in the container
-with the working tree from outside of the container:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ mv /usr/local/searxng/searxng-src  /usr/local/searxng/searxng-src.old
-        $ ln -s /share/SearXNG/ /usr/local/searxng/searxng-src
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux \
-          mv /usr/local/searxng/searxng-src /usr/local/searxng/searxng-src.old
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux \
-          ln -s /share/SearXNG/ /usr/local/searxng/searxng-src
-
-Now we can develop as usual in the working tree of our desktop system.  Every
-time the software was changed, you have to restart the SearXNG service (in the
-container):
-
-.. tabs::
-
-  .. group-tab:: uwsgi@searxng
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux systemctl restart uwsgi@searxng
-
-
-Remember: :ref:`working in containers` .. here are just some examples from my
-daily usage:
-
-To *inspect* the SearXNG instance (already described above):
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ ./utils/searxng.sh inspect service
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux ./utils/searxng.sh inspect service
-
-Run :ref:`makefile`, e.g. to test inside the container:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ make test
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux  make test
-
-
-
-To install all prerequisites needed for a :ref:`buildhosts`:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ ./utils/searxng.sh install buildhost
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux ./utils/searxng.sh install buildhost
-
-
-To build the docs on a buildhost :ref:`buildhosts`:
-
-.. tabs::
-
-  .. group-tab:: ``[root@searxng-archlinux SearXNG]`` (GUEST)
-
-     .. code:: bash
-
-        $ make docs.html
-
-  .. group-tab:: desktop (HOST)
-
-     .. code:: bash
-
-        $ sudo -H ./utils/lxc.sh cmd searxng-archlinux make docs.html

-     |searxng| lrwxrwxrwx 1 searxng searxng ... /usr/local/searxng/searxng-src -> /share/SearXNG
-
-On code modification the instance has to be restarted (see :ref:`uWSGI
-maintenance`):
-
-.. code:: bash
-
-   $ sudo -H ./utils/lxc.sh cmd searxng-archlinux systemctl restart uwsgi@searxng

-   - `Docker and iptables (docker.com) <https://docs.docker.com/network/iptables/#docker-on-a-router/>`__
-
-There is a conflict in the ``iptables`` setup of Docker & LXC.  If you have
-docker installed, you may find that the internet connectivity of your LXD
-containers no longer work.
-
-Whenever docker is started (reboot) it sets the iptables policy for the
-``FORWARD`` chain to ``DROP`` `[ref]

-  :FORWARD DROP [7048:7851230]
-
-A handy solution of this problem might be to reset the policy for the
-``FORWARD`` chain after the network has been initialized.  For this create a
-file in the ``if-up`` section of the network (``/etc/network/if-up.d/iptable``)
-and insert the following lines::
-
-  #!/bin/sh
-  iptables -F FORWARD
-  iptables -P FORWARD ACCEPT
-
-Don't forget to set the execution bit::
-
-  sudo chmod ugo+x /etc/network/if-up.d/iptable
-
-Reboot your system and check the iptables rules::

-=================
-
-The intention of the *SearXNG LXC suite* is to build up a suite of containers
-for development tasks or :ref:`buildhosts <Setup SearXNG buildhost>` with a very
-small set of simple commands.  At the end of the ``--help`` output the SearXNG

-     containers: searxng-ubu2004 searxng-ubu2204 searxng-fedora35 searxng-archlinux
-
-As shown above there are images and containers build up on this images.  To show
-more info about the containers in the *SearXNG LXC suite* call ``show suite``.
-If this is the first time you make use of the SearXNG LXC suite, no containers
-are installed and the output is::

-  WARN:  container searxng-archlinux does not yet exists
-
-If you do not want to run a command or a build in all containers, **you can
-build just one**. Here by example in the container that is build upon the
-*archlinux* image::
-
-  $ sudo -H ./utils/lxc.sh build searxng-archlinux
-  $ sudo -H ./utils/lxc.sh cmd searxng-archlinux pwd
-
-Otherwise, to apply a command to all containers you can use::
-
-  $ sudo -H ./utils/lxc.sh build
-  $ sudo -H ./utils/lxc.sh cmd -- ls -la .
-
-Running commands
-----------------
-
-**Inside containers, you can run scripts** from the :ref:`toolboxing` or run
-what ever command you need.  By example, to start a bash use::
-
-  $ sudo -H ./utils/lxc.sh cmd searxng-archlinux bash
-  INFO:  [searxng-archlinux] bash
-  [root@searxng-archlinux SearXNG]#
-
-.. _Good to know:
-
-Good to know
-------------
-
-Each container shares the root folder of the repository and the command
-``utils/lxc.sh cmd`` **handle relative path names transparent**::
-
- $ pwd
- /share/SearXNG
-
- $ sudo -H ./utils/lxc.sh cmd searxng-archlinux pwd
- INFO:  [searxng-archlinux] pwd
- /share/SearXNG
-
-The path ``/share/SearXNG`` will be different on your HOST system.  The commands
-in the container are executed by the ``root`` inside of the container.  Compare
-output of::
-
-  $ ls -li Makefile
-  47712402 -rw-rw-r-- 1 markus markus 2923 Apr 19 13:52 Makefile
-
-  $ sudo -H ./utils/lxc.sh cmd searxng-archlinux ls -li Makefile
-  INFO:  [searxng-archlinux] ls -li Makefile
-  47712402 -rw-rw-r-- 1 root root 2923 Apr 19 11:52 Makefile
-  ...
-
-Since the path ``/share/SearXNG`` of the HOST system is wrapped into the
-container under the same name, the shown ``Makefile`` (inode ``47712402``) in
-the output is always the identical ``/share/SearXNG/Makefile`` from the HOST
-system.  In the example shown above the owner of the path in the container is
-the ``root`` user of the container (and the timezone in the container is
-different to HOST system).
-
-
-.. _lxc.sh install suite:
-
-Install suite
--------------
-
-.. sidebar::  further read
-
-   - :ref:`working in containers`
-   - :ref:`FORCE_TIMEOUT <FORCE_TIMEOUT>`
-
-To install the complete :ref:`SearXNG suite <lxc-searxng.env>` into **all** LXC_
-containers leave the container argument empty and run::
-
-  $ sudo -H ./utils/lxc.sh build
-  $ sudo -H ./utils/lxc.sh install suite
-
-To *build & install* suite only in one container you can use by example::
-
-  $ sudo -H ./utils/lxc.sh build searxng-archlinux
-  $ sudo -H ./utils/lxc.sh install suite searxng-archlinux
-
-The command above installs a SearXNG suite (see :ref:`installation scripts`).
-To :ref:`install a nginx <installation nginx>` reverse proxy (or alternatively
-use :ref:`apache <installation apache>`)::
-
-  $ sudo -H ./utils/lxc.sh cmd -- FORCE_TIMEOUT=0 ./utils/searxng.sh install nginx
-
-Same operation just in one container of the suite::
-
-  $ sudo -H ./utils/lxc.sh cmd searxng-archlinux FORCE_TIMEOUT=0 ./utils/searxng.sh install nginx
-
-The :ref:`FORCE_TIMEOUT <FORCE_TIMEOUT>` environment is set to zero to run the
-script without user interaction.
-
-To get the IP (URL) of the SearXNG service in the containers use ``show suite``
-command.  To test instances from containers just open the URLs in your
-WEB-Browser::
-
-  $ sudo ./utils/lxc.sh show suite | grep SEARXNG_URL
-
-  [searxng-ubu2110]      SEARXNG_URL          : http://n.n.n.170/searxng
-  [searxng-ubu2004]      SEARXNG_URL          : http://n.n.n.160/searxng
-  [searxnggfedora35]     SEARXNG_URL          : http://n.n.n.150/searxng
-  [searxng-archlinux]    SEARXNG_URL          : http://n.n.n.140/searxng
-
-Clean up
---------
-
-If there comes the time you want to **get rid off all** the containers and
-**clean up local images** just type::
-
-  $ sudo -H ./utils/lxc.sh remove
-  $ sudo -H ./utils/lxc.sh remove images
-
-
-.. _Setup SearXNG buildhost:
-
-Setup SearXNG buildhost
-=======================
-
-You can **install the SearXNG buildhost environment** into one or all containers.
-The installation procedure to set up a :ref:`build host<buildhosts>` takes its
-time.  Installation in all containers will take more time (time for another cup
-of coffee). ::
-
-  sudo -H ./utils/lxc.sh cmd -- ./utils/searxng.sh install buildhost
-
-To build (live) documentation inside a archlinux_ container::
-
-  sudo -H ./utils/lxc.sh cmd searxng-archlinux make docs.clean docs.live
-  ...
-  [I 200331 15:00:42 server:296] Serving on http://0.0.0.0:8080
-
-To get IP of the container and the port number *live docs* is listening::
-
-  $ sudo ./utils/lxc.sh show suite | grep docs.live
-  ...
-  [searxng-archlinux]  INFO:  (eth0) docs.live:  http://n.n.n.140:8080/
-
-
-.. _lxc.sh help:
-
-Command Help
-============
-
-The ``--help`` output of the script is largely self-explanatory:
-
-.. program-output:: ../utils/lxc.sh --help
-
-
-.. _lxc-searxng.env:
-
-SearXNG suite config
-====================
-
-The SearXNG suite is defined in the file :origin:`utils/lxc-searxng.env`:
