Deploy Action Reference¶
In general, the deployments do not modify the downloaded files. Where the LAVA scripts and test definitions need to be added, these are first prepared as a standalone tarball. Exceptions are described where relevant in each section.
Deploy action roles¶
Download files required by the job to the dispatcher, decompressing only if requested.
Prepare a LAVA overlay tarball containing the test definitions and LAVA API scripts, only if a Test Action Reference action is defined.
Depending on the deployment, apply the LAVA overlay tarball to the deployment.
Deploy does not support repeat blocks but does support Retry on failure.
Required parameters¶
Every deployment must specify a to
parameter. This value is then used
to select the appropriate strategy class for the deployment which, in turn,
will require other parameters to provide the data on how to deploy to the
requested location. Additionally, all the required parameters are marked with
a *
Overlays¶
LAVA can insert user provided overlays into your images right after the download step.
In the url block, you can add a dictionary called overlays that will list the overlays to add to the given resource.
- deploy:
images:
rootfs:
url: http://example.com/rootfs.ext4.xz
compression: xz
format: ext4
overlays:
modules:
url: http://example.com/modules.tar.xz
compression: xz
format: tar
path: /
In order to insert overlay into an image, you should specify the image format. Currently LAVA supports cpio (newc format) and ext4 images.
The overlays should be archived using tar. The path is relative to the root of the image to update. This path is required.
Parameter List¶
to: docker¶
Pull a docker image from the official or a private docker hub.
- deploy:
to: docker
os: debian
image: debian:stretch
os¶
Optional parameter to let LAVA know which OS the container is running
image¶
Either the name of the docker image to pull or a dictionary with:
name¶
Name of the docker image to pull
local¶
true
if the image is local, false
by default.
- deploy:
to: docker
os: debian
image:
name: my-local-docker-debian-image
local: true
to: download¶
Download is a special type of deployment in which the files specified in the
URL are downloaded as in any other deployment type and does nothing more. If
there is a LXC protocol requested then the
downloaded files are copied to LAVA_LXC_HOME. These downloaded files
can then be referred by the URL scheme lxc:///
in subsequent actions.
images¶
Download deployments support images to be downloaded and saved along with copying to LAVA_LXC_HOME when LXC protocol is available. The list of images will depend on the test job and the test device.
label¶
The label is arbitrary text, that refers to the image key that will get downloaded as specified in url *
- deploy:
to: download
images:
rootfs:
url: http://example.com/rootfs.img.gz
compression: gz
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.
- deploy:

{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
compression¶
If the image is compressed, the compression method must be specified. If image is compressed but compression method is not specified it will be downloaded as uncompressed.
archive¶
Some system images are compressed as a tarball (.tar.*
), these images
need the archive
option specified to unpack the system image correctly.

to: fastboot¶
See also
images¶
Fastboot deployments support a range of images to be downloaded and deployed to
the device. The list of images will depend on the test job and the test device.
The available elements determine the command arguments passed to fastboot
inside the LXC i.e., the partition to be flashed.
partition¶
The partition is a text string which specifies the partition to which the
image will be flashed using the fastboot
command.
In the example, the partition to be flashed on the DUT is system
.
Note
The partition text is passed to fastboot command as given in the
job, for example, fastboot flash system /lava-lxc/rootfs.img
, hence
take caution to pass the right partition name.

The default value for this parameter is true
. Some system images are
shipped as sparse images which needs special handling with tools such as
simg2img
and img2simg
, in order to apply LAVA specific overlays to it.
By default LAVA assumes the image to which apply-overlay
is specified is a
sparse image.

to: musca¶
This deployment method allows deployment of software to musca devices. Currently supported musca devices: musca a, musca b1 and musca s1.
The board is powered on and the mass storage device is mounted.
The test binary is copied to the MSD and then the MSD is unmounted.
When the board processes it, the MSD will be re-exposed to the dispatcher,
at which point this is re-mounted and LAVA will check for the presence of a FAIL.TXT
file, in case of errors.
Note
Some initial setup steps are required to ensure that the Musca device serves it’s MSD when it is powered on.
Check here for details
on how to setup the board to auto-boot when it is programmed or turned on.
Ensure DETAILS.TXT
on the MSD shows “Auto Reset” and “Auto Power” are activated.
Note
LAVA won’t deploy firmware to the Musca board and so it must be fixed per device. Firmware used is available here.

to: nbd¶
Used to support NBDroot deployments, e.g. using a initrd with nbd-client
and pivot_root. Files are downloaded to a temporary directory on the worker,
the rootfs is shared through xnbd-server and the filenames are substituted into the
bootloader commands specified in the device configuration or overridden in the
job. The files to download typically include a kernel but can also include any
file which the substitution commands need for this deployment. URL support is
handled by the python requests
module.

{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
modules¶
This is not supported in the deployment strategy. Modules must be part of the filesystem already.
initrd¶
The initrd contains all necessary files, daemons and scripts to bring-up the nbd-client and pivot_root to the final rootfs. There are a few important aspects:
The nbdroot filesystem will not be modified prior to the boot. The filesystems are using security labels and this would alternate the fs. The lava test shell needs to be extracted at runtime with transfer_overlay.
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.

{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
archive¶
Some system images are compressed as a tarball (.tar.*
), these images
need the archive
option specified to unpack the system image correctly.
- deploy:
images:
boot:
url: http://example.com/boot.tar.xz
compression: xz
archive: tar
compression¶
The NBD filesystem image is unpacked into a temporary directory onto the dispatcher in a location supported by NBD server. The compression method must be specified so that the filesystem can be unpacked.
md5sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.
- deploy:
images:
system:
url: http://example.com/system.img.xz
compression: xz
md5sum: d8784b27867b3dcad90cbea66eacc264
sha256sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.:
- deploy:

to: recovery¶
Deployment to recovery
allows the use of device dictionary commands
and an LXC test shell to automate recovery mode operations on some
DUTs.
Successful use of recovery deployments require support by the admins and by the test writers.
Note
In recovery mode, the device may have different identifiers and might no longer be unique. This can result in requiring a new device-type template and only creating one device of this type on any one worker. Not all devices can support automated recovery mode.
Additionally, recovery deployments are blind - there is udev
support to add the device to the LXC but no serial connection, so no
output will be read from the DUT. All tools and libraries required
to execute the recovery test shell need to be added to the LXC. For
example, using an earlier test shell inside the LXC.
Download scripts and binaries to transfer to the device
Copy the downloaded artifacts into the LXC.
Ensure that power to the device is OFF
Execute the
recovery_mode_command
to use relays or similar to put the device into recovery mode, in a dedicated namespace.{% set recovery_mode_command = [ '/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 1 -s off', '/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 2 -s on'] %}
Apply power.
- boot: namespace: recovery timeout: minutes: 5 method: recovery commands: recovery
The test job would then define a test action which executes the scripts using the downloaded files and completes recovery. This script may have to wait for the device to appear and as the device may then have an unpredictable device node name, an action to create a symlink with a known name is likely to be required. The use of LXC ensures that only one suitable device exists, as long as the device configuration and recovery mode operations only require a single device matching the check in the recovery script.
Example: for the HiKey 6220, the recovery mode operations could be executed as steps in the test shell as follows:
run:
steps:
- find /dev/ -name 'ttyUSB*' -xdev -type c -quit -exec ln -s {} /dev/recovery ';'
- python /lava-lxc/hisi-idt.py --img1=/lava-lxc/l-loader.bin -d /dev/recovery
# fastboot should wait for the device to reset here
# udev rule copes with adding it to the LXC once it appears
- fastboot flash ptable /lava-lxc/ptable-linux.img
- fastboot flash ptable /lava-lxc/fip.bin
- fastboot flash ptable /lava-lxc/nvme.img
# next boot action takes care of exiting from recovery mode
Important
Make these commands portable so that the same script
can be used to deploy new firmware to the device outside of LAVA.
When using a test shell to handle firmware deployments, make sure
that a failure of any test shell command fails the job by using
lava-test-raise
.
command(){
if [ -n "$(which lava-test-case || true)" ]; then
echo $2
$2 && lava-test-case "$1" --result pass || lava-test-raise "$1"
else
echo $2
$2
fi
}
Then call the function with two arguments, the test case name (with no spaces) and the command to execute (with substitutions for the parameterized variables for the files which were downloaded by the test job):
command 'hisi-idt-l-loader' "python ${SCRIPT} --img1=${LOADER} -d /dev/recovery"
Take note of the quoting in this shell example. The first parameter
can use single quotes but the second parameter must use double
quotes "
so that the values of $SCRIPT
and $LOADER
are
substituted. Portable scripts are free to use whatever language you
prefer.

https://git.linaro.org/lava-team/refactoring.git/tree/scripts/hikey-6220-recovery.sh
When the test shell exits, the device is reset using a second boot recovery
operation.
- boot:
namespace: recovery
timeout:
minutes: 5
method: recovery
commands: exit
A recovery_exit_command
must be specified in the device dictionary.
{% set recovery_exit_command = [
'/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 1 -s on',
'/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 2 -s off'] %}
Test jobs can terminate early (either through bugs or cancellation), so
it is important to include the recovery_exit
support in the
power_off_command
so that the device is left in a suitable state
for the next test job in the queue.
{% set power_off_command = ['/usr/bin/pduclient --daemon calvin --hostname pdu --command off --port 04',
'sleep 30',
'/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 1 -s on',
'/home/neil/lava-lab/shared/lab-scripts/eth008_control -a 10.15.0.171 -r 2 -s off'] %}
The additional command may take some time to complete, so the timeout of the power_off action may also need extending in the device-type template.
{% set action_timeout_power_off = 60 %}
to: sata¶
Deploy unchanged images to secondary SATA media. Any bootloader inside the image will not be used. Instead, the files needed for the boot are specified in the deployment. The entire physical device is available to the secondary deployment. Secondary relates to the expected requirement of a primary boot (e.g. ramdisk or NFS) which provides a suitable working environment to deploy the image directly to the secondary device. See Secondary media.
Not all devices support SATA media.
The test writer needs to provide the following information about the image:
kernel *¶
kernel: The path, within the image, to the kernel which will be used by the bootloader.
ramdisk¶
ramdisk: (optional). If used, must be a path, within the image, which the bootloader can use.
dtb *¶
dtb: The path, within the image, to the dtb which will be used by the bootloader.
UUID *¶
UUID: The UUID of the partition which contains the root filesystem of the booted image.
boot_part *¶
boot_part: the partition on the media from which the bootloader can read the kernel, ramdisk & dtb.
Note
If the image mounts the boot partition at a mounpoint below the root directory of the image, the path to files within that partition must not include that mountpoint. The bootloader will read the files directly from the partition.
to: ssh¶
SSH methods can support two types of deployment.

to: tftp¶
Used to support TFTP deployments, e.g. using U-Boot. Files are downloaded to a
temporary directory in the TFTP tree and the filenames are substituted into the
bootloader commands specified in the device configuration or overridden in the
job. The files to download typically include a kernel but can also include any
file which the substitution commands need for this deployment. URL support is
handled by the python requests
module.

kernel¶
To deploy images using TFTP, arguments will be downloaded to a configured tftp directory.
type¶
Specifies the type of kernel being downloaded. Some bootloaders, for example
U-Boot, use this information to determine the load addresses and boot commands.
Certain device types may also need the downloaded file to
be converted to a uImage
.
(Replaces the previous support for specifying the boot type (bootm
,
booti
or bootz
).
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.

{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
modules¶
A tarball of kernel modules for the supplied kernel. The file must be a tar file and the compression method must be specified. If the kernel requires these modules to be able to locate the rootfs, e.g. when using NFS or if certain required filesystem drivers are only available as modules, the ramdisk can be unpacked and the modules added. Modules may also be required to run tests within the ramdisk itself.
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.

archive¶
Some system images are compressed as a tarball (.tar.*
), these images
need the archive
option specified to unpack the system image correctly.
- deploy:
images:
boot:
url: http://example.com/boot.tar.xz
compression: xz
archive: tar
compression¶
If the image is compressed, the compression method must be specified. If image is compressed but compression method is not specified it will be downloaded as uncompressed.
ramdisk¶
The ramdisk needs to be unpacked and modified in either of the following two use cases:
the lava test shell is expected to run inside the ramdisk, or
the deployment needs modules to be added to the ramdisk, for example to allow the device to load the network driver to be able to locate the NFS.
To unpack the ramdisk, the test writer needs to specify details about how the ramdisk is prepared and used. If these details are not provided, the ramdisk will not be unpacked (potentially causing the test to fail in the above two use cases).

compression¶
If the image is compressed, the compression method must be specified. If image is compressed but compression method is not specified it will be downloaded as uncompressed.
Note
Additional NFS mount options can be added via job definition context
i.e. nfsvers
argument which specifies which version of the NFS protocol
to use.
context:
extra_nfsroot_args: ",nolock,nfsvers=3"
persistent_nfs¶
A persistent NFS URL can be used instead of a compressed tarball. See Persistence for the limitations of persistent storage.
Warning
LAVA does not shut down the device or attempt to unmount the NFS filesystem when the job finishes; the device is simply powered off. The test writer needs to ensure that any background processes started by the test have been stopped before the test finishes.
address *¶
Specifies the address to use for the persistent filesystem.
The address
must include the IP address of the NFS server and the full
path to the directory which contains the root filesystem, separated by a single
colon. In the YAML, all values containing a colon must be quoted:
- deploy:
to: tftp
kernel:
url: http://example.com/vmlinuz-4.9.0-4-armmp
type: zimage
persistent_nfs:
address: "127.0.0.1:/var/lib/lava/dispatcher/tmp/armhf/stretch"
to: tmpfs¶
Used to support QEMU device types which run on a dispatcher. The file is downloaded to a temporary directory and made available as one or more images, appending specified arguments to a predetermined QEMU command line:
- deploy:
timeout:
minutes: 4
to: tmpfs
images:
rootfs:
image_arg: -drive format=raw,file={rootfs}
url: http://example.com/stretch.img.gz
sha256sum: b5cdb3b9e65fec2d3654a05dcdf507281f408b624535b33375170d1e852b982c
compression: gz
images¶
To deploy images using QEMU, arguments need to be prepared and then modified to include the downloaded location of the image files. The test writer needs to specify the format of the image and other image-specific arguments for QEMU along with a placeholder label which is unique for this test job.
label¶
The label is arbitrary text, used to match the other parameters to the placeholder so that the final value can be substituted in place of the placeholder.
In the example, the label is rootfs
and the url
includes the matching
placeholder {rootfs}
. If the final location of the downloaded image
is /tmp/tmp.rG542e/large-stable-6.img
then the final argument passed to
QEMU would include -drive format=raw,file=/tmp/tmp.rG542e/large-stable-6.img
.
Note
Take note of the syntax. Single brace before and after the label and no whitespace. This is test job syntax, not Jinja.
- deploy:
timeout:
minutes: 4
to: tmpfs
images:
rootfs:
image_arg: -drive format=raw,file={rootfs}
url: http://example.com/stretch.img.gz

compression: gz
image_arg¶
The image_arg
determines how QEMU handles the image. The arguments must
include a placeholder label which exactly matches
the key of the same block in the list of images. The actual location of the
downloaded file will then replace the placeholder. Multiple images can be
supplied but the test writer is responsible for ensuring that the image_arg
make sense to QEMU.
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.

), these images
need the archive
option specified to unpack the system image correctly.
- deploy:

compression: xz
archive: tar
compression¶
If the image is compressed, the compression method must be specified. If image is compressed but compression method is not specified it will be downloaded as uncompressed.
md5sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.

to: usb¶
Deploy unchanged images to secondary USB media. Any bootloader inside the image will not be used. Instead, the files needed for the boot are specified in the deployment. The entire physical device is available to the secondary deployment. Secondary relates to the expected requirement of a primary boot (e.g. ramdisk or NFS) which provides a suitable working environment to deploy the image directly to the secondary device. See Secondary media.
Not all devices support USB media.
The test writer needs to provide the following information about the image:
kernel *¶
kernel: The path, within the image, to the kernel which will be used by the bootloader.
ramdisk¶
ramdisk: (optional). If used, must be a path, within the image, which the bootloader can use.
dtb *¶
dtb: The path, within the image, to the dtb which will be used by the bootloader.
UUID *¶
UUID: The UUID of the partition which contains the root filesystem of the booted image.
boot_part *¶
boot_part: the partition on the media from which the bootloader can read the kernel, ramdisk & dtb.
Note
If the image mounts the boot partition at a mounpoint below the root directory of the image, the path to files within that partition must not include that mountpoint. The bootloader will read the files directly from the partition.
The UUID can be obtained by writing the image to local media and checking the
contents of /dev/disk/by-uuid
The ramdisk may need adjustment for some bootloaders (like U-Boot), so mount the local media and use something like:
mkimage -A arm -T ramdisk -C none -d /mnt/boot/init.. /mnt/boot/init..u-boot
to: vemsd¶
VEMSD
or Versatile Express MicroSD is a deployment method to
write a new recovery image.
recovery_image¶
Download the URL ready to be unpacked onto the MicroSD.
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.
- deploy:
timeout:
minutes: 120
to: tftp
kernel:
url: http://{FILE_SERVER_IP}/linux/Image-imx8mmevk.bin
type: image
persistent_nfs:
address: "{FILE_SERVER_IP}:/var/lib/lava/dispatcher/tmp/linux/imx8mm_rootfs"
dtb:
url: http://{FILE_SERVER_IP}/linux/imx8mm-evk.dtb
os: debian
Note
- admin can define any placeholder and assign an address to it in device dictionary.
LAVA then substitutes the placeholders in job with the static_info to generate a new url.
{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
compression¶
If the image is compressed, the compression method must be specified.
zip
files are downloaded without decompression and unpacked
directly onto the filesystem of the VEMSD.
gz
files are required to be a .tar.gz
and will be decompressed
during download and then unpacked onto the filesystem of the VEMSD.
to: mps¶
MPS is a deployment method used by the MPS2 device which is similar to the support for to: vemsd
images¶
recovery_image¶
Download the URL ready to be unpacked onto the USB filesystem of the MPS2 device.
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.

dtb:
url: http://{FILE_SERVER_IP}/linux/imx8mm-evk.dtb
os: debian
Note
- admin can define any placeholder and assign an address to it in device dictionary.

If the image is compressed, the compression method must be specified.
zip
files are downloaded without decompression and unpacked
directly onto the filesystem of the USB filesystem of the MPS2.
gz
files are required to be a .tar.gz
and will be decompressed
during download and then unpacked onto the filesystem of the VEMSD.
test_binary¶
Download test binary to MPS device and rename if required.
Multiple test binaries can be flashed in the same deploy action by listing all
of them. The keys should start with test_binary_
.
- deploy:
to: mps
images:
recovery_image:
url: mps2_sse200_an512.tar.gz
compression: gz
test_binary_1:
url: tfm_sign.bin
test_binary_2:
url: mcuboot.bin
url *¶
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.

LAVA then substitutes the placeholders in job with the static_info to generate a new url.
{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
rename¶
Renames the test_binary if required
If the recovery_image expects to flash a specific image and the file downloaded is not named this way, this option will save it with a different name on the board.
If not specified, the the test_binary is copied as-is, no renaming takes place.
- deploy:
to: mps
images:
recovery_image:
url: mps2_sse200_an512.tar.gz
compression: gz
test_binary_1:
url: tfm_sign_20191121.bin
renam: tfm_sign.bin
to: uuu¶
uuu specific deploy method is very similar with to: fastboot method, with a required boot
partition.
Partitions are usable within uuu boot method using the partition name.
- deploy:
to: uuu
images:
boot:
url: https://.../imx-boot-sd.bin-flash
system:
url: https://../imx-image-multimedia.rootfs.wic
images¶
uuu deployments support a range of images to be downloaded and deployed to the device. The list of images will depend on the test job and the test device.
Warning
Partition boot
is required by any uuu boot method.
partition¶
The partition is a text string which specifies the partition to which the
image will be flashed using uuu
commands.
Note
Each partition can be referenced using {partition_name}
within uuu boot method e.g. :
- deploy:
to: uuu
images:
boot:
url: https://.../imx-boot-sd.bin-flash
- boot:
method: uuu
commands:
- uuu: -b sd {boot}
Specifies the URL to download. All downloads are checksummed using md5sum
and sha256sum
URLs are checked during the test job validation to ensure that the file can be downloaded. Missing files will cause the test job to end as Incomplete.
URLs must use one of the supported schemes, the first element of the URL.
URLs allow placeholder for http, https and file schema.
- deploy:
timeout:
minutes: 120
to: tftp
kernel:
url: http://{FILE_SERVER_IP}/linux/Image-imx8mmevk.bin
type: image
persistent_nfs:
address: "{FILE_SERVER_IP}:/var/lib/lava/dispatcher/tmp/linux/imx8mm_rootfs"
dtb:
url: http://{FILE_SERVER_IP}/linux/imx8mm-evk.dtb
os: debian
Note
- admin can define any placeholder and assign an address to it in device dictionary.
LAVA then substitutes the placeholders in job with the static_info to generate a new url.
{% set static_info = [{'FILE_SERVER_IP': "10.192.244.104"}] %}
compression¶
If the image is compressed, the compression method must be specified. If image is compressed but compression method is not specified it will be downloaded as uncompressed.
apply-overlay¶
Use this to apply LAVA specific overlays to image.
- deploy:
to: uuu
images:
system:
url: http://example.com/system.img.xz
compression: xz
apply-overlay: true
sparse¶
- deploy:
to: uuu
images:
system:
url: http://example.com/system.img.xz
compression: xz
sparse: true
The default value for this parameter is true
. Some system images are
shipped as sparse images which needs special handling with tools such as
simg2img
and img2simg
, in order to apply LAVA specific overlays to it.
By default LAVA assumes the image to which apply-overlay
is specified is a
sparse image.
See also
If the image is not a sparse image then this should be explicitly mentioned, so that LAVA will treat the image as non-sparse ext4 image.
- deploy:
to: uuu
images:
system:
url: http://example.com/system.ext4.xz
compression: xz
sparse: false
See also
The sparse image format is defined in sparse_format in the Android platform source code.
md5sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.
- deploy:
images:
system:
url: http://example.com/system.img.xz
compression: xz
md5sum: d8784b27867b3dcad90cbea66eacc264
sha256sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.:
- deploy:
images:
system:
url: http://example.com/system.img.xz
compression: xz
sha256sum: e0e82b5adfae84ff97f4f6488e5b4c64b0dfc7ad8a37b4bcbb887d9f85a6be0a
sha512sum¶
The checksum of the file to download can be provided, and if so it will be checked against the downloaded content. This can help to detect multiple potential problems such as misconfigured caching or corrupted downloads. If compression is used, the checksum to specify is the checksum of the compressed file, irrespective of whether that file is decompressed later.:

sha512sum: e0e82b5adfae84ff97f4f6488e5b4c64b0dfc7ad8a37b4bcbb887d9f85a6be0a
os *¶
The operating system of the image may be specified if the LAVA scripts need to use the LAVA install helpers to install packages or identify other defaults in the deployment data. However, this support is deprecated for most use cases.
If os
is used, the value does not have to be exact. A similar
operating system can be specified, based on how the test job operates.
If the test shell definition uses the deprecated LAVA install helpers
(by defining install:
steps), then any os
value which provides
the same installation tools will work. For example, operating systems
which are derivatives of Debian can use os: debian
without needing
explicit support for each derivative because both will use apt
and
dpkg
.
See also
Test jobs which execute operating system installers will require
the deployment data for that installer, so os
will need to be
specified in those test jobs. When the Lava install helpers are
removed, the elements of deployment data which are required for
installers will be retained.
Portable test definitions do not need to specify os
at all, as long
as the test definition is not expected to run on a DUT running Android.
Important
Please read the notes on Write portable test definitions - all test writers are strongly encouraged to drop all use of the LAVA install helpers as this support is deprecated and is expected to be removed by moving to support for an updated Lava-Test Test Definition.
Not all deployment methods support all types of operating system.
Not all devices can support all operating systems.
