Managing a LAVA LAB using the Debian packages

● Debian Packages● What are the supported releases?● How do I install?● How do I upgrade?

● Initial Deployment● How do I manage my instance?● New salt configuration

● What changed?● Why?

● Demo: Automated LAVA install

● What’s in each release?● What’s next● Q/A

Agenda

● Debian● Jessie● Sid

● Ubuntu● Trusty (14.04)● Unicorn (14.10)

● Upstream packages● In Jessie, Sid, and Unicorn● Trusty installation

● you must add an alternate apt source● deb http://people.linaro.org/~neil.williams/ubuntu/ trusty main● apt-get install postgresql before lava

● Architectures● armhf (Finally!)● amd64● arm64 (Experimental)

What are the supported releases?

● apt-get install postgresql lava (amd64)● apt-get install postgresql lava-server (armhf, arm64, amd64)

● Installation requires interaction without preseed● Single, or distributed installation● Instance name● Postgresql port

● Configure apache2● If the default configuration is acceptable you can enable by entering the following

● a2dissite 000-default● a2ensite lava-server.conf● service apache2 reload

● Create superuser● lava-server manage createsuperuser

● You will be prompted for user, e-mail and password

● Login to your new instance● http://127.0.0.1

How do I install?

● The entire system● apt-get update● apt-get install lava-server lava-server-doc lava-dispatcher

● The server● apt-get update● apt-get install lava-server lava-server-doc

● The dispatcher● apt-get update● apt-get install lava-dispatcher

How do I upgrade?

● Start/Stop/Restart● service lava-server start/stop/restart

● Dispatcher Configuration● /etc/lava-dispatcher/lava-dispatcher.conf

● Device and Device Type● /etc/lava-dispatcher/devices/● /etc/lava-dispatcher/device-types/

● /var/lib/lava-server/default/media/● TFTP/NFS/TMP Directory

● /var/lib/lava/dispatcher/tmp/● Source Code

● /usr/lib/python2.7/dist-packages/lava_*

How do I manage my instance?

● Add Device Helper● /usr/share/lava-server/add_device.py Usage: add_device.py devicetype hostname [-p pduport] [-t telnetport]

● PDU Daemon● Why was this created?● How do I use it?● How can I extend it

How do I manage my instance?

LAVA installing LAVA

Demo: Automated LAVA install

● Simplified● No dependance on custom modules● Most dependencies are now enforced by apt● TFTP and NFS are configured by package not salt

● Upgrades● pkg.latest for lava-*

● External tools● Add apt sources for the following

● linaro-image-tools● lava-android-test

● Code for the the LAVA Lab Configuration● http://git.linaro.org/lava/lava-lab.git

Salt Configuration

● What’s in the current release?● 2014.07

● http://releases.linaro.org/14.07/components/lava

● Monthly cadence● Updates are pushed out first week of each month

● Run the latest and greatest from the development channel● deb http://images.validation.linaro.org/staging-repo/ sid main● Recommend you use a staging server for monitoring ‘bleeding-edge’ code

Releases

● Discussion on LAB migration● Q&A for those that have a functional LAB that need to upgrade

● Where are other packages?● Looking for package maintainers

What’s next
