The *searx suite* (:origin:`lxc-searx.env `) is loaded by default, every time you start the ``lxc.sh`` script (*you do not need to care about*). 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 *searx suite*, you have to build the :ref:`LXC suite containers ` initial. But be warned, **this might take some time**:: $ sudo -H ./utils/lxc.sh build 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 `. If you do not want to build all containers, **you can build just one**:: $ sudo -H ./utils/lxc.sh build searx-ubu1804 *Good to know ...* Eeach container shares the root folder of the repository and the command ``utils/lxc.sh cmd`` **handles relative path names transparent**, compare output of:: $ sudo -H ./utils/lxc.sh cmd -- ls -la Makefile ... In the containers, you can run what ever you want, e.g. to start a bash use:: $ sudo -H ./utils/lxc.sh cmd searx-ubu1804 bash INFO: [searx-ubu1804] bash root@searx-ubu1804:/share/searx# 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 Install suite ============= To install the complete :ref:`searx suite (includes searx, morty & filtron) ` into all LXC_ use:: $ sudo -H ./utils/lxc.sh install suite The command above installs a searx suite (see :ref:`installation scripts`). To get the IP (URL) of the filtron 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 filtron [searx-ubu1604] INFO: (eth0) filtron: http://n.n.n.135:4004/ [searx-ubu1804] INFO: (eth0) filtron: http://n.n.n.141:4004/ [searx-ubu1910] INFO: (eth0) filtron: http://n.n.n.137:4004/ [searx-ubu2004] INFO: (eth0) filtron: http://n.n.n.127:4004/ [searx-fedora31] INFO: (eth0) filtron: http://n.n.n.18:4004/ [searx-archlinux] INFO: (eth0) filtron: http://n.n.n.12:4004/ Running commands ================ **Inside containers, you can use make or run scripts** from the :ref:`toolboxing`. By example: to setup a :ref:`buildhosts` and run the Makefile target ``test`` in the archlinux_ container:: sudo -H ./utils/lxc.sh cmd searx-archlinux ./utils/searx.sh buildhost sudo -H ./utils/lxc.sh cmd searx-archlinux make test Setup searx buildhost ===================== You can **install the searx buildhost environment** into one or all containers. The installation procedure to set up a :ref:`build host` takes its time. Installation in all containers will take more time (time for another cup of coffee).:: sudo -H ./utils/lxc.sh cmd -- ./utils/searx.sh buildhost To build (live) documentation inside a archlinux_ container:: sudo -H ./utils/lxc.sh cmd searx-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 ... [searx-archlinux] INFO: (eth0) docs-live: http://n.n.n.12:8080/ .. _lxc.sh help: Overview ======== The ``--help`` output of the script is largely self-explanatory: .. program-output:: ../utils/lxc.sh --help .. _lxc-searx.env: searx suite =========== .. literalinclude:: ../../utils/lxc-searx.env :language: bash
