  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.conf 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": ["192.168.1.14", "127.0.0.1", "localhost"],
        "CSRF_COOKIE_SECURE": false,
        "SESSION_COOKIE_SECURE": false,
        "EVENT_NOTIFICATION": true,
        "EVENT_TOPIC": "lava-server",
        "INTERNAL_EVENT_SOCKET": "tcp://lava-publisher:5557"
    }


  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

    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"]                                                                           
    }


  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:

...

You then need to bind your  host certificates to container by adding following line in 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

...

So far unable to get this to work, with job error "Unable to (un)mount USB device: /dev/disk/by-id/usb-MBED_VFS_0240000048824e45000b700bdd8900418761000097969900-0:0" on Ubuntu 18.04, despite the record existingEnabled auto reset mode by creating a `auto_rst.cfg` file while holding the reset button down (MSD command documentation for 0246). Post reset, Details.txt reports "Auto Reset: 1."

When adding a new job, however, the job stalls waiting for USB CDC to appear (60s timeout) and the only way for the test to pass is to manually remove and reconnect the USB cable within the 60 second delay. The CDC device is being passed through to the two docker images, as evidenced by the following commands:
