Re: [Lava-users] running commands locally from a Lava job - lava-users - op-lists.linaro.org

      Hi Lava users,
I am using the sample you sent me last week to run tradefed: https://gist.github.com/mwasilew/e6e80a351d43388b1c3342098012ec
Until we have a real device to run on Tradefed we decided to use it with qemu, so the question is:
1.  How do we deploy android on qemu via Lava?
  2.  How to boot android via lava?
Do you have any sample job for the above questions?
george

Here is the answer I have just received from Linaro via their mail-list.
They say it is not a good idea to build tradefed with lava, but it can be used in the scenario to run TF from an LXC container - they have said.
Tradefed should be built from outside Lava.

Thanks for the answers,

What do you mean by  "with LXC container acting as a host side ". It is an LXC container on the machine where Lava runs and inside this containes runs Tradefed?

yes, exactly. Here is an example job definition:
https://gist.github.com/mwasilew/e6e80a351d43388b1c3342098012ec5c
I can't share the actual job and logs as there are passwords included.

Where can I find an example of these Jobs? Could you help me with an link, or sample jobs?

I would say it's a bad idea. LAVA is not meant for building stuff. It can do that but you will need to hack around quite a lot. Secondly IIUC you need to have dependency between build and run steps. If you want to implement this using LAVA this implies multi-node job. There is no other way LAVA will manage dependencies and timings between executions. So this is getting pretty complicated already.
LAVA is already running tradefed jobs (CTS and VTS) using real hardware and it's a pretty common use case. There are 2 implementations of this. One is using single node job with LXC container acting as a host side. Other is using multinode and can shard tests between multiple devices. However tradefed packages are built outside of lava and downloaded before job starts.
To sum up, I think what you're trying to do is not best suited for LAVA. However it might be possible given some effort spent on experimenting.

Yes
For one job to build tradefederation from inside a docker container.
For the second job to run Google TradeFederation from the docker container.
Would be that possible with Lava?

George,
Do I understand correctly you would like to use LAVA as a building tool?

Hi Lava users,
Is it possible to run commands inside a lava job test-section, locally,  from a Lava Job?
Ex:
cd /media/sh_shared_folders
docker build -t tradefed .
We have the following setup:
A machine with Linux Ubuntu;
an Oracle Virtual Box  VM on the machine with a Xubuntu distro
image inside the VM we have created 3 Docker containers:
one with the Jenkins
second one with Lava
third is created for the purpose of running Google TradeFederation
against the Android device
(The AOSP source tree is available to the VM via shared_folders
and the docker container has also access to it. (via docker run -v
dir_host:dir_container) )
What we what to achieve is to have 2 jobs in Lava :
one for building the Docker image for the purpose of building
TradeFederation inside
                                                                                                                            Ex. Running these commande locally:

                                                 source

./build/make/envsetup.sh
                                                 lunch

<device-target>
                                                  make

tradefed-all -j8
second using the above image, instantiate, create a container
which should run TradeFederation against the android device
connected to the machine
What I need is to be able to run commands locally inside the VM (on Xubuntu distro) from a Lava job.  For these we have to somehow not send the command to qemu but run them locally.
Is this possible? If yes, how can we achieve this?
