  1. Optional: Setup access for local IP/host

    If you are running lava on a machine with a fixed IP (eg: a dedicated computer on your local network) you will want to modify the  overlays/lava-server/etc/lava-server/settings.confd/01-unsecure.yaml file to allow access.  You'll want to modify the ALLOWED_HOSTS line to add the ip or hostname of the machine.  In the example below, the ip 192.168.1.14 was added, you'll want to keep 127.0.0.1 and localhost .

    Code Block
    languageyml
    linenumberstrue
    {
    "HTTPS_XML_RPC": false,
    "MOUNT_POINT": "/",
    "STATIC_URL": "/static/",
    "ALLOWED_HOSTS"
CSRF_COOKIE_SECURE: false
SESSION_COOKIE_SECURE: false
ALLOWED_HOSTS: ["192.168.1.14", "127.0.0.1", "localhost"],

    "EVENT_NOTIFICATION": true,
    "EVENT_TOPIC": "lava-server",
    "INTERNAL_EVENT_SOCKET": "tcp://lava-publisher:5557"
}
    Optional: Add the proxy 

  2. Optional: Add the proxy settings in lite-lava-dispatcher and ser2net images
    It might be required to define proxy setting in lite-lava-dispatcher/Dockerfile and ser2net/Dockerfile
     Code Block
    languagebash
    ENV http_proxy=http://<user>:<pwd>@<proxy>:<port>
ENV https_proxy=http://<user>:<pwd>@<proxy>:<port>

  3. Optional: Configure DNS in /etc/docker/daemon.json
    Do this only if you are sure you need this. Otherwise, hardcoding a particular (local) DNS server may lead to issues when using another network connection, etc.
    Get host DNS:
     Code Block
    languagebash
    nmcli dev show | grep 'IP4.DNS'
    Set reported value in /etc/docker/daemon.json:
     Code Block
    languageyml
    {                                                                          
    "dns": ["w.x.y.z"]                                                                           
}
    Restart docker:
     Code Block
    languageyml
    sudo service docker restart

  4. Run commands to build docker images and startup lava
     Code Block
    languagebash
    docker-compose build
make
    You'll see output of docker fetching and building the images, and then all LAVA containers starting up, followed by a fair amount of logging from LAVA itself as it starts up.  This may take a few minutes to complete.
    Here are some examples of the output one can expect during this phase:

  5.  Verify lava is running
     
    You can verify that lava has completed startup by trying to connect to the LAVA webserver in a web browser by going to localhost.
    Here's what the startup webpage should look like in your web browser:
...
  1. Add a user
    Replace <USERNAME> and <PASSWD>, if this command is successful there will be no output.
     Code Block
    languagebash
    docker exec -it lava-server lava-server manage users add <USERNAME> --superuser --staff --passwd <PASSWD>

  2. Login in & Create API token
    Now that we have a user created we need to go back to the web browser and login to create an API token.  The API token is used by software like  lavacli  to connect to Lava's XML-RPC API interface.  To login in, there should be a  Sign In  link on the top right of the starting webpage.  Or you can try and go to this URL: http://localhost/accounts/login/?next=/ (if you are connecting via a fixed ip/host replace  localhost  here with that IP/hostname).

     

    Login Page:

     
    Now log in with the  <USERNAME>  and  <PASSWORD>  that were used in step 1 of this section.

  3. Create API token
    Now that we are logged in we need to create the API token.  Follow the steps documented here to create a token:
    https://master.lavasoftware.org/static/docs/v2/first_steps.html#authentication-tokens 
    Make sure to copy the token value as we will need it in the next step.

  4. Setup lavacli identities with API token
    The  lavacli  tool allows us to issue various commands to Lava on the command line.  This tool utilizes the API token to authenticate.  It can be configured with different identity profiles.  The command below adds an identity called 'lava-docker'.  Then in future  lavacli  commands we can do  lavacli -i lava-docker <CMD> <...> .  Note: if we have lava setup on a fixed IP/hostname you can replace  localhost  in the URL below with that IP/hostname.  Replace  <USERNAME>  and  <TOKEN>  In the command below:
     Code Block
    languagebash
    lavacli identities add --username <USERNAME> --token <TOKEN> --uri http://localhost/RPC2 lava-docker 

Setup 
...
Now that we've got Lava configured and running, lavacli setup, we now need to add the board to the Lava database of known hardware.  First we need to register the device-type with Lava.  Lava setups a number of known device-types (list of known device-types).  For this example the FRDM-K64F board is a supported/known device type ( frdm-k64f ).  Out of the box Lava is not configured to know about any device types.  Device types are defined as YAML files and Lava utilizes jinja2 templates to describe configurable aspects of the YAML.  Its outside of the scope of this guide on how to create a new device type.
Setup the device type
 (Note how we use the  -i lava-docker  identity we created in the previous steps).
 Code Block
languagebash
lavacli -i lava-docker device-types add frdm-k64f
Add a board instance
Now that the device-type is registered, we need to create a device instance.  In the example below we are creating a device instance called frdm-k64f-01 (the naming follows the Cambridge lab setup: https://lite.validation.linaro.org/scheduler/alldevices) .  
 Code Block
languagebash
lavacli -i lava-docker devices add --type frdm-k64f --worker lava-dispatcher frdm-k64f-01
...
Connect the board
...
Generate the parameters for the board instance

contrib/board-setup-helper.py -d <DEVICE_SERIAL_NUM> -t <DEVICE_TYPE>
command to run 
Here we use the serial number ( 0240000031754e45001c0019948500046461000097969900 ) and device type ( frdm-k64f ) from before. We also store board config in the file named frdm-k64f-01.jinja2 (device type, suffixed by board number, in case there can be several boards of the same type).

output from command 
Here we see that the -u option reports back the udev rules that we would need to add for this board.  These rules match the ones we specified back in the host setup stage.
 Code Block

ser2net/ser2net.conf file 
ser2net is a utility that allows exposing a serial port device as a network connection.  We generate

frdm-k64f-01.jinja2 file 
As mentioned before, the frdm-k64f-01.jinja2 file provides unique details about the specific board
...
 board_id : serial number
...
 usb_mass_device : device file for USB mass storage device that one would mount.  We use the /dev/disk/by-id so that the name is persistent for the board
...
 connection_command : command to connect to serial port, the port number here matches the  ser2net.conf  file.
 resets_after_flash  : all newer daplink firmwares on the FRDM-K64F do not reset after the board is flashed. So, we set this option to "false".  If you have very old DAPLink firmware and want to postpone upgrading it (not recommended), you can set this option to "true".
 Code Block

{% set connection_command = 'telnet ser2net 5001' %}
{% set resets_after_flash = false %}
Set the device dictionary
Because of the client/server nature of Lava we need to tell the server to update the device dictionary for our specific board with the parameters for the board.  We utilize  lavacli  for this purpose.  The device dictionary is kept by the lava server and a full dictionary that is composed of the device-type template + the board specific dictionary are sent to the lava dispatcher on every job that is submitted.  Thus any updates to the dictionary for a given board will take effect for any future job submissions.
 Code Block
languagebash
lavacli -i lava-docker devices dict set frdm-k64f-01 frdm-k64f-01.jinja2
Restart ser2net
Since we updated the ser2net.conf file we need to send a SIGHUP (-1) signal to the ser2net daemon to cause it to re-read the config file.
 Code Block
languagebash
docker exec -it lava-ser2net sh -c 'kill -1 `cat /var/run/ser2net.pid`'
Setup proxy settings for LAVA (optional)
If you are behind a proxy, you may need to add localhost in your 'no_proxy' environment variable in order for lava dispatcher to resolve it in subsequent commands:
 Code Block
languagebash
export no_proxy="localhost,127.0.0.0"
The lava-master container also needs to have proxy settings setup. To do so, copy the env.yaml file from the container into a the 'overlays' directory on the host:
 Code Block
languagebash
mkdir -p overlays/lava-master/etc/lava-server
docker cp lava-master:/etc/lava-server/env.yaml overlays/lava-master/etc/lava-server/env.yaml
Edit the file using your favorite editor to update the lines that define the proxy variables to match your settings:
 Code Block
languageyml
# A dictionary of (key, value) that will be added to the inherited environment.
# If a key does not already exist in the inherited environment, it's added.
# default: an empty dictionary
overrides:
  LC_ALL: C.UTF-8
  LANG: C
  http_proxy: <replace with your proxy setting>
  https_proxy: <replace with your proxy setting>
Save the file. Then open 'docker-compose.yaml' in your favorite editor and add a line at the end of the lava-master's 'volumes:' section to automatically copy the file:
 Code Block
languageyml
  lava-master:
    container_name: lava-master
    image: ${DC_SERVER_IMAGE}
    volumes:

    - ./overlays/lava-master/etc/lava-server/env.yaml:/etc/lava-server/env.yaml:ro
Save the file. Hit ctrl-c in the window where you previously typed 'make' to terminate the docker-compose session, and relaunch it by running 'make' again. Now the file would be automatically populated in the lava-master container.
Setup the board
Now that we've got Lava configured and running, lavacli setup, we now need to add the board to the Lava database of known hardware.  First we need to register the device-type with Lava.  Lava setups a number of known device-types (list of known device-types).  For this example the FRDM-K64F board is a supported/known device type ( frdm-k64f ).  Out of the box Lava is not configured to know about any device types.  Device types are defined as YAML files and Lava utilizes jinja2 templates to describe configurable aspects of the YAML.  Its outside of the scope of this guide on how to create a new device type.
  1. Setup the device type
     (Note how we use the  -i lava-docker  identity we created in the previous steps).
     Code Block
    languagebash
    lavacli -i lava-docker device-types add frdm-k64f
    When running this command, if you get an error such as "Unable to connect: 400 Client Error: Bad Request for url: http://<user>:<token>@localhost/RPC2", you need to set up proxy settings for LAVA as described in previous step.
  2. Add a board instance
    Now that the device-type is registered, we need to create a device instance.  In the example below we are creating a device instance called frdm-k64f-01 (the naming follows the Cambridge lab setup: https://lite.validation.linaro.org/scheduler/alldevices) .  
     Code Block
    languagebash
    lavacli -i lava-docker devices add --type frdm-k64f --worker lava-dispatcher frdm-k64f-01
    Note: the  --worker lava-dispatcher  argument in this command is used to specify the name of the Lava dispatcher that the board is physically connected to.  The Lava architecture allows multiple dispatchers to be connected to a single server.  The docker solution we are utilizing is configured for a single dispatcher called lava-dispatcher.

  3. Connect the board
    Back in the Building & Starting up the LAVA Docker images section we mentioned to disconnect the board.  Please connect the board back to your computer.  If you didn't disconnect the board in the Building stage that's ok, please disconnect and reconnect the board.  The reason we wanted the board disconnect until this point is that we wanted the docker container for the lava-dispatcher up and running before the board was connected.  If you remember we added some  udev  rules back in the host setup stage.  Those udev rules invoke the  usb-passthrough  utility.  The purpose of that utility is to "setup" the various usb devices (serial, usb mass storage, debug) in the lava-dispatch container.  The udev rules rely on the hotplug event associated with the board being plugged in.  Thus if we plugged in the board before the docker containers were running the containers wouldn't know about the board.

  4. Generate the parameters for the board instance
    Now that the board is connected we need to let lava know some details specific to this board.  In the case of the FRDM-K64F board we need to let Lava know what the serial number of the board is, the device file for the mass storage device, and how to connect to the serial port.  These parameters are specified in a jinja2 template format.  There is a helper script that given the device type and serial number of the board will create or report information associated with setting up the board.  The  contrib/board-setup-helper.py  at a minimum needs the  -d  (serial number) and  -t  (device type - matches the lava device type) flags.  We also specify the -u flag in our example to report the udev rules.  Finally there are a  -s  and  -b  options to specify the ser2net config filename and board jinja filename.  By default the script will look to modify  ser2net/ser2net.conf  if the  -s  options is not specified and will create board.jinja2 if the  -b  option is not specified.

    • output from command 
      Here we see that the -u option reports back the udev rules that we would need to add for this board.  These rules match the ones we specified back in the host setup stage.

    • ser2net/ser2net.conf file 
      ser2net is a utility that allows exposing a serial port device as a network connection.  We generate

    • frdm-k64f-01.jinja2 file 
      As mentioned before, the frdm-k64f-01.jinja2 file provides unique details about the specific board
      •  board_id : serial number
      •  usb_mass_device : device file for USB mass storage device that one would mount.  We use the /dev/disk/by-id so that the name is persistent for the board
      •  connection_command : command to connect to serial port, the port number here matches the  ser2net.conf  file.
      •  resets_after_flash  : all newer daplink firmwares on the FRDM-K64F do not reset after the board is flashed. So, we set this option to "false".  If you have very old DAPLink firmware and want to postpone upgrading it (not recommended), you can set this option to "true".

  5. Set the device dictionary
    Because of the client/server nature of Lava we need to tell the server to update the device dictionary for our specific board with the parameters for the board.  We utilize  lavacli  for this purpose.  The device dictionary is kept by the lava server and a full dictionary that is composed of the device-type template + the board specific dictionary are sent to the lava dispatcher on every job that is submitted.  Thus any updates to the dictionary for a given board will take effect for any future job submissions.
     Code Block
    languagebash
    lavacli -i lava-docker devices dict set frdm-k64f-01 frdm-k64f-01.jinja2

  6. Restart ser2net
    Since we updated the ser2net.conf file we need to send a SIGHUP (-1) signal to the ser2net daemon to cause it to re-read the config file.
     Code Block
    languagebash
    docker exec -it lava-ser2net sh -c 'kill -1 `cat /var/run/ser2net.pid`'

Starting the udev event forwarder

You then need to bind your  host certificates to container by adding following line in lite-lava-docker-compose/docker-compose.yaml:
 Code Block
languageyml
  lava-master:
    container_name: lava-master
    image: ${DC_SERVER_IMAGE}
    volumes:
    ...
    - /usr/local/share/ca-certificates:/usr/local/share/ca-certificates:ro
Then, run the following command in the container and go back to job start step.
 Code Block
update-ca-certificates
...
  1. Clone the repository: git clone https://github.com/Linaro/lite-lava-docker-compose (this will clone "lite" branch, which is the default branch for the LITE setup).
  2. Start with plugging your board(s) into USB ports, and use "udevadm monitor -e | grep -i ID_SERIAL_SHORT" command to note their serial numbers. Each number should be put into files named devices/<lava_device_name>.serial. <lava_device_name> is the name of device which will be created on the LAVA side, and should in turn follow <device_type>-NN naming pattern. For example, for a (first) FRDM-K64F board, the file name is devices/frdm-k64f-01.serial
  3. With all involved boards still connected to USB, run "make board-configs". This will create (or update) contrib/LAVA.rules, devices/*.jinja2 etc. files, as described in the "manual" section of this document. You will need to re-run "make board-configs" whenever you add/remove boards, or have serial numbers change.
  4. make install - This will install files needed on the host, e.g. LAVA.rules and passthru script(s). Re-run this target when board set/properties (and thus LAVA.rules) changes.
  5. make build - Build docker-compose images. Re-run if image content is supposed to change (for example, after LAVA version upgrade).
  6. make (make all) - Start up containerize LAVA setup . This also takes care of starting any host daemons (like udev forwarding daemon) too. In consequence, take care to unplug devices before this step and plug them back once daemons are in running idle.
  7. make lava-setup - Perform initial semi-automated LAVA configuration - run this once per LAVA setup, then can be run again to update configuration (see also sub-targets utilized by this target). It would attempt to setup all boards (Note: There may be some "soft" errors in the console output if some boards are not being connected and their board jinja files are missing (were not created with "make board-configs" above). These can be ignored if the board is not of interest to you.)
  8. make testjob - Submit a "smoke test" testjob running against a QEMU (follow it at http://localhost/scheduler/job/1)
  9. make stop - Stop LAVA setup (and any host-side daemons).
  10. make clean - Tear down current LAVA setup, losing all data (use make followed by make lava-setup to start again).
