==========
|

|

Usually 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.

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
|
||||
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
|
||||
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 and not to mix up all the
|
||||
prerequisites from various projects on developer's desktop is always a good
|
||||
choice.**

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::

|
||||
$ sudo -H ./utils/lxc.sh show suite

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

.. _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 conatiner 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 ouput 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 conatiner (and the timezone in the container is
|
||||
different to HOST system).
