Prerequisites

...

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
   language yml linenumbers true
   { "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
   language bash
   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
   language bash
   nmcli dev show | grep 'IP4.DNS'

   Set reported value in /etc/docker/daemon.json:

   Code Block
   language yml
   { "dns": ["w.x.y.z"] }

   Restart docker:

   Code Block
   language yml
   sudo service docker restart

   
   

4. Run commands to build docker images and startup lava

   Code Block
   language bash
   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 lite-lava-docker-compose/docker-compose.yaml:

  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.

update-ca-certificates

...

• board-configs, install, build - "host-side" setup, "run once", or whenever things outside specific LAVA container setup update.
• make, lava-setup, stop, clean - "container-side", use to managed lifecycle of current LAVA container.

Development Setup

NOTE: This section is RFC and WIP.

The purpose of the local LAVA setup is to work on improving test coverage for various software and hardware components, and oftentimes, this requires making changes to LAVA software. This section outlines a (possible) process of making this possible.

Repository structure setup:

1. In the same parent repository where you cloned lite-lava-docker-compose, clone https://git.lavasoftware.org/lava/lava (or, if you have an active user account on https://git.lavasoftware.org (recommended to submit changes back to LAVA), use "git clone git@git.lavasoftware.org:lava/lava.git" ).
2. Besides LAVA upstream repository, the LITE team also maintains own fork repository, used to integrate WIP changes from various LITE developers, before the changes are merged upstream. This repository allows different developers to have a common baseline, and help each other with testing. It's recommended to add it as an additional remote to the clone produced in previous step:
   • cd lava
   • git remote add lite git@github.com:Linaro/lite-lava.git
   • git checkout lite

Following the setup above will allow one to easily access both upstream tags/branches (master, or particular release), and LITE team's own branches, and switching between branches is often required to contribute back to LAVA.
