lava-lab

Simple Lava lab recipe to generate a basic Lava lab instance with a Qemu device

The instance is composed of docker containers, a lava-server (lava_server), lava-dispatcher (lava_worker0) and a file-server (fileserver).

• The lava-server (master) shcedules the test jobs, administers devices ands stores the results
• The lava-dispatcher (worker) deploys software (images) on connected devices, and processes the test jobs
• The file-server store artifacts (e.g. images to test, test templates, etc...)

Prerequisite

• docker
• docker-compose

Init/Update repo

git clone -b master --single-branch https://github.com/ci-box/lava-lab.git
cd lava-lab
git submodule update --init

Create and Start instance

make

or if your user is not part of docker group:

sudo make

Play

If you run command locally you can then access the Lava web user interface at localhost:8042 Since this instance defines a Qemu device and Qemu health-check job, you will see the health check job scheduled and executed.

That's all! you can now submit your own jobs (https://validation.linaro.org/static/docs/v2/explain_first_job.html)

Advanced

Makefile

Makefile is mainly a docker wrapper, following helpers are available:

make run

Build and execute instance.

make start

Build and launch instance (detached from terminal)

make stop

Stop a previoulsy started instance.

make clean

Stop and remove instance

Customize instance

Everything takes place in docker-compose.yaml file
