Hi Milosz,
I have tried Interactive test method for small test suite (5-10 testcases). And true, Interactive test can't generate overlay. But my actual suite contains more than 200 testcases. And for each testcase execution have to invoke the command in job description as a *name: command: *in interactive test module looks tricky for me to maintain . that's why i am looking for alternate solution!!.
Thanks Milosz for your time and support :)
Regards, Nagendra S

Thanks Milosz !! for the quick response.
As you mention in the earlier comment --> The only other option I
found is applying overlay using "download"
action. This only works for: "cpio (newc format) and ext4 images
You mean, if I build a root file system with ext4 format(like boot from
SD-Ext4 ) will it help out? If So, Can you please point me to the sample job description for my reference.
I haven't used it for a long time so I don't remember exactly how to do that, sorry :(
And Is interactive method suites in this case. Becz DUT having
limitation of using lava-test-shell/monitor methods to test my suite from LAVA.
My End goal here is LAVA test method should pick up/phrase the pass/fail
returns from the test return values.
hmm, have you tried it? I don't think interactive test generates an overlay as it's executed from the worker (over serial) rather than from shell.

Hi Milosz, I wasn't able to download an overlay over HTTP(wget or curl) due to

I am curious to now, How to modify my rootfs in a LAVA job to
include overlay. Can you please share with me the sample job/supported device-type jinja2. (or) Is any recipe available in yocto to make this possible as i am using yocto as a build tool to generate images and OS --> Linux 5.4.25-yocto-standard
Overlay is applied in deployment. Here is a (almost) full list: https://master.lavasoftware.org/static/docs/v2/actions-deploy.html
Not all deployment methods support rootfs modifications. I think (I didn't try so I'm not 100% sure) you could download your images using 'downloads' deployment. Add overlay using docker postprocessing. After this flash the images to your device as usual. How exactly would this be done, I don't know. Example deployment with postprocessing would look like this:
- deploy: to: downloads # this is correct. There are 2 similar deployments:
download; downloads images: image: url: your_image.wic.gz compression: gz postprocess: docker: image: docker_image_name # this can come from hub.docker.io or some other registry steps: - shell script step1 - shell script step2 ...
- deploy: to: flasher # or some other method. I'm using flasher with my
devices
images: image: url: downloads://your_image.wicAs I wrote, I didn't try this so this is just speculation. How to access overlay (if it's possible?) in the postprocess remains an open question. I'll ask Antonio, maybe he has an example.
I took a quick look at the code and I don't think this is possible. There are 2 issues here:
- postprocess steps happens before overlay is prepared
- you could apply overlay in flasher script but there is no way to
get the path from LAVA This would be possible but requires changes in LAVA. At least this is how I understand the code. LAVA would need to extract "file" from "compress-overlay" namespace and expose it to a custom script (via env variable for example).
The only other option I found is applying overlay using "download" action. This only works for: "cpio (newc format) and ext4 images".

Lava-worker had all the binaries available by lava-overlay method.
Are you able to download overlay over HTTP (with wget or curl)?
This
is done in boot section:
- boot: ... transfer_overlay: download_command: cd /home ; wget unpack_command: tar -C -xzf
Without transfer_overlay you would need to modify your rootfs in a LAVA job to include overlay. Depending on your OS it might be easy, hard or impossible (if the image is signed for example).
