+Developing in Linux containers [202006]
+=======================================
+
+.. _LXC: https://linuxcontainers.org/lxc/introduction/
+
+.. sidebar:: Audience
+
+   This blog post is written for experienced admins and developers / readers
+   should have a serious meaning about: *distributed*, *merge* and *linux
+   container*.
+
+.. contents:: Contents
+   :depth: 2
+   :local:
+   :backlinks: entry
+
+In PR :PR:`1803` we added a lot of scripts to Searx's boilerplate.  In this blog
+post I will show you, how you can make use of them in *distributed and
+heterogeneous development cycles* (TL;DR; jump to the :ref:`blog-lxcdev-202006
+abstract`).
+
+Motivation
+==========
+
+Normally in our development cycle, we edit the sources and run some test and/or
+builds by using ``make`` 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 pyenv` encapsulate a lot for us, but they
+do not have access to all prerequisites.  For example, there may have
+dependencies on packages that are installed on the developer's desktop, but
+usually are not preinstalled on a server or client system.  Another examples
+are; settings have been made to the software on the developer's host that would
+never be set on a *production* system.
+
+*Linux Containers* (LXC_) are isolate environments and not to mix up on
+developer's all the prerequisites of all the projects he contribute to, is
+always a good choice.
+
+The scripts from PR :PR:`1803` can divide in those to install and maintain
+software:
+
+- :ref:`searx.sh`
+- :ref:`filtron.sh`
+- :ref:`morty.sh`
+
+and the script :ref:`lxc.sh`, with we can scale our installation, maintenance or
+even development tasks over a stack of containers, what we call: *Searx's 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
+
+     .. code:: sh
+
+        $ 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
+
+     .. code:: sh
+
+        $ cd ~/Downloads
+        $ git clone https://github.com/asciimoo/searx.git
+        $ cd searx
+
+The :ref:`lxc-searx.env` consists of several images, see ``export
+LXC_SUITE=(...`` near by :origin:`utils/lxc-searx.env#L19`.  For this blog post
+we exercise on a archlinux_ image.  The container of this image is named
+``searx-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
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh remove searx-archlinux
+        $ sudo -H ./utils/lxc.sh build searx-archlinux
+
+.. sidebar:: The ``searx-archlinux`` container
+
+   is the base of all our exercises here.
+
+In this container we install all services :ref:`including searx, morty & filtron
+<lxc.sh install suite>` in once:
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh install suite searx-archlinux
+
+To proxy HTTP from filtron and morty in the container to the outside of the
+container, install nginx into the container.  Once for the bot blocker filtron:
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          ./utils/filtron.sh nginx install
+        ...
+        INFO:  got 429 from http://10.174.184.156/searx
+
+and once for the content sanitizer (content proxy morty):
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          ./utils/morty.sh nginx install
+        ...
+        INFO:  got 200 from http://10.174.184.156/morty/
+
+.. sidebar:: Fully functional searx suite
+
+   From here on you have a fully functional searx suite running with bot blocker
+   (filtron) and Web content sanitizer (content proxy morty) needed for a
+   *privacy protecting* search engine.
+
+On your system, the IP of your ``searx-archlinux`` container differs from
+http://10.174.184.156/searx, just open the URL reported in your installation
+protocol in your WEB browser from the desktop to test the instance from outside
+of the container.
+
+In such a searx suite admins can maintain and access the debug log of the
+different services quite easy.
+
+.. _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 using ``./utils/lxc.sh cmd
+searx-archlinux``:
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux bash
+        INFO:  [searx-archlinux] bash
+        [root@searx-archlinux searx]# pwd
+        /share/searx
+
+The prompt ``[root@searx-archlinux ...]`` signals, that you are the root user in
+the searx-container.  To debug the running searx instance use:
+
+.. tabs::
+
+  .. group-tab:: root@searx-archlinux
+
+     .. code:: sh
+
+        $ ./utils/searx.sh inspect service
+        ...
+        use [CTRL-C] to stop monitoring the log
+        ...
+
+Back in the browser on your desktop open the service http://10.174.184.156/searx
+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 searx's settings file and restarts the searx uwsgi application.  To
+debug services from filtron and morty analogous use:
+
+.. tabs::
+
+  .. group-tab:: root@searx-archlinux
+
+     .. code:: sh
+
+        $ ./utils/filtron.sh inspect service
+        $ ./utils/morty.sh inspect service
+
+Another point we have to notice is that each service (:ref:`searx <searx.sh>`,
+:ref:`filtron <filtron.sh>` and :ref:`morty <morty.sh>`) runs under dedicated
+system user account with the same name (compare :ref:`create searx user`).  To
+get a shell from theses accounts, simply call one of the scripts:
+
+.. tabs::
+
+  .. group-tab:: root@searx-archlinux
+
+     .. code:: sh
+
+        $ ./utils/searx.sh shell
+        $ ./utils/filtron.sh shell
+        $ ./utils/morty.sh shell
+
+To get in touch, open a shell from the service user (searx@searx-archlinux):
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+        ./utils/searx.sh shell
+        // exit with [CTRL-D]
+        (searx-pyenv) [searx@searx-archlinux ~]$ ...
+
+The prompt ``[searx@searx-archlinux]`` signals that you are logged in as system
+user ``searx`` in the ``searx-archlinux`` container and the python *virtualenv*
+``(searx-pyenv)`` environment is activated.
+
+.. tabs::
+
+  .. group-tab:: searx@searx-archlinux
+
+     .. code:: sh
+
+        (searx-pyenv) [searx@searx-archlinux ~]$ pwd
+        /usr/local/searx
+
+
+
+Wrap production into developer suite
+====================================
+
+In this section we will see how to change the *"Fully functional searx 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`:
+
+- searx setup in: ``/etc/searx/settings.yml``
+- searx user's home: ``/usr/local/searx``
+- virtualenv in: ``/usr/local/searx/searx-pyenv``
+- searx software in: ``/usr/local/searx/searx-src``
+
+The searx software is a clone of the ``GIT_URL`` (see :ref:`makefile setup`) and
+the working tree is checked out from the ``GIT_BRANCH``.  With the use of the
+:ref:`searx.sh` the searx service was installed as :ref:`uWSGI application
+<searx uwsgi>`.  To maintain this service, we can use ``systemctl`` (compare
+:ref:`service architectures on distributions <uwsgi configuration>`).
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          systemctl stop uwsgi@searx
+
+With the command above, we stopped the searx uWSGI-App in the archlinux
+container.
+
+The uWSGI-App for the archlinux dsitros is configured in
+:origin:`utils/templates/etc/uwsgi/apps-archlinux/searx.ini`, from where at
+least you should attend the settings of ``uid``, ``chdir``, ``env`` and
+``http``::
+
+  env = SEARX_SETTINGS_PATH=/etc/searx/settings.yml
+  http = 127.0.0.1:8888
+
+  chdir = /usr/local/searx/searx-src/searx
+  virtualenv = /usr/local/searx/searx-pyenv
+  pythonpath = /usr/local/searx/searx-src
+
+If you have read the :ref:`"Good to know section" <lxc.sh>` 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
+searx installation into a developer one, we simple have to create a smylink to
+the **transparent** reposetory from the desktop.  Now lets replace the
+repository at ``searx-src`` in the container with the working tree from outside
+of the container:
+
+.. tabs::
+
+  .. group-tab:: container becomes a developer suite
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          mv /usr/local/searx/searx-src /usr/local/searx/searx-src.old
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          ln -s /share/searx/ /usr/local/searx/searx-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 searx service (in the
+conatiner):
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          systemctl restart uwsgi@searx
+
+
+Remember: :ref:`working in containers` .. here are just some examples from my
+daily usage:
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     To *inspect* the searx instance (already described above):
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          ./utils/searx.sh inspect service
+
+     Run :ref:`makefile`, e.g. to test inside the container:
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          make test
+
+     To install all prerequisites needed for a :ref:`buildhosts`:
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          ./utils/searx.sh install buildhost
+
+     To build the docs on a buildhost :ref:`buildhosts`:
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh cmd searx-archlinux \
+          make docs
+
+.. _blog-lxcdev-202006 abstract:
+
+Abstract
+========
+
+We build up a fully functional searx suite in a archlinux container:
+
+.. code:: sh
+
+   $ sudo -H ./utils/lxc.sh install suite searx-archlinux
+
+To access HTTP from the desktop we installed nginx for the services inside the
+conatiner:
+
+.. tabs::
+
+  .. group-tab:: [root@searx-archlinux]
+
+     .. code:: sh
+
+        $ ./utils/filtron.sh nginx install
+        $ ./utils/morty.sh nginx install
+
+To wrap the suite into a developer one, we created a symbolic link to the
+repository which is shared **transparent** from the desktop's file system into
+the container :
+
+.. tabs::
+
+  .. group-tab:: [root@searx-archlinux]
+
+     .. code:: sh
+
+	$ mv /usr/local/searx/searx-src /usr/local/searx/searx-src.old
+	$ ln -s /share/searx/ /usr/local/searx/searx-src
+	$ systemctl restart uwsgi@searx
+
+To get remarks from the suite of the archlinux container we can use:
+
+.. tabs::
+
+  .. group-tab:: desktop
+
+     .. code:: sh
+
+        $ sudo -H ./utils/lxc.sh show suite searx-archlinux
