Developing in Linux Containers

==============================

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`
|
||||
|
||||
.. _lxcdev install searxng:
|
||||
|
||||
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)

We build up a fully functional SearXNG suite in a archlinux container:

|
||||
.. code:: bash
|
||||
|
||||
$ sudo -H ./utils/lxc.sh build searxng-archlinux
|
||||
$ sudo -H ./utils/lxc.sh install suite searxng-archlinux
|
||||
...
|
||||
Developer install? (wraps source from HOST into the running instance) [YES/no]
|
||||
|
||||
To wrap the suite into a developer one answer ``YES`` (or press Enter).
|
||||
|
||||
.. code:: text
|
||||
|
||||
link SearXNG's sources to: /share/SearXNG
|
||||
=========================================
|
||||
|
||||
mv -f "/usr/local/searxng/searxng-src" "/usr/local/searxng/searxng-src.backup"
|
||||
ln -s "/share/SearXNG" "/usr/local/searxng/searxng-src"

|
||||
|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
|
||||
|
||||
To access HTTP from the desktop we installed nginx for the services inside the
|
||||
container:
|
||||
|

.. code:: bash
|
||||
|
||||
$ sudo -H ./utils/lxc.sh cmd -- FORCE_TIMEOUT=0 ./utils/searxng.sh install nginx

With the use of *Linux Containers* (LXC_) we can scale our tasks over a stack of
|
||||
containers, what we call the: *lxc suite*. The :ref:`lxc-searxng.env` is
|
||||
loaded by default, every time you start the ``lxc.sh`` script (*you do not need
|
||||
to care about*).

|
||||
Install LXD
|
||||
===========
|
||||
|
||||
Before you can start with containers, you need to install and initiate LXD_
|
||||
once::
|
||||
|
||||
$ snap install lxd
|
||||
$ lxd init --auto
|
||||
|
||||
To make use of the containers from the *SearXNG suite*, you have to build the
|
||||
:ref:`LXC suite containers <lxc.sh help>` initial. But be warned, **this might
|
||||
take some time**::
|
||||
|
||||
$ sudo -H ./utils/lxc.sh build
|
||||
|
||||
.. sidebar:: hint
|
||||
|
||||
If you have issues with the internet connectivity of your containers read
|
||||
section :ref:`internet connectivity docker`.
|
||||
|
||||
A cup of coffee later, your LXC suite is build up and you can run whatever task
|
||||
you want / in a selected or even in all :ref:`LXC suite containers <lxc.sh
|
||||
help>`.
|
||||
|
||||

||||
Internet Connectivity & Docker
|
||||
------------------------------
|
||||
|
||||
.. sidebar:: further read
|
||||
|
||||
- `Docker blocking network of existing LXC containers <https://github.com/docker/for-linux/issues/103>`__
|
||||
- `Docker and IPtables (fralef.me) <https://fralef.me/docker-and-iptables.html>`__
|
||||
- `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]
|
||||
<https://docs.docker.com/network/iptables/#docker-on-a-router>`__::
|
||||
|
||||
$ sudo -H iptables-save | grep FORWARD
|
||||
:FORWARD ACCEPT [7048:7851230]
|
||||
: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::
|
||||
|
||||
$ sudo -H iptables-save | grep FORWARD
|
||||
:FORWARD ACCEPT [7048:7851230]
|
||||
:FORWARD ACCEPT [7048:7851230]

.. _searxng lxc suite:
|
||||
|
||||
SearXNG LXC suite
|
||||
=================
|
||||
|
||||
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
|
||||
suite from the :ref:`lxc-searxng.env` is introduced::
|
||||
|
||||
$ sudo -H ./utils/lxc.sh --help
|
||||
...
|
||||
LXC suite: searxng
|
||||
Suite includes installation of SearXNG
|
||||
images: ubu2004 ubu2204 fedora35 archlinux
|
||||
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::
|
||||
|
||||
$ sudo -H ./utils/lxc.sh show suite
|
||||
|
||||
LXC suite (searxng-*)

|

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
|
||||

|
||||
|
||||
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
|
||||
|
||||

|

||||

|
||||
|
||||

|
||||
|
||||
$ sudo ./utils/lxc.sh show suite | grep docs.live
