Preinstalls and preconfigures the latest LAVA dispatcher release.
To build an image locally, execute the following from the directory you cloned the repo:
sudo docker build -t lava-slave .
To run the image from a host terminal / command line execute the following:
sudo docker run -it -v /dev:/dev -p 69:69/udp -p 80:80 -h <HOSTNAME> --privileged kernelci/lava-slave-docker:latest
Where HOSTNAME is the hostname used during the container build process (check the docker build log), as that is the name used for the worker configuration. You can use lava-docker as the pre-built container hostname.
Enviroment variables are available to help setup state within the container.
Where LAVA_MASTER is the IP address for your LAVA server.
sudo docker run -it -v /dev:/dev -p 69:69/udp -p 80:80 -e LAVA_MASTER='<lava master ip>' -e LAVA_SERVER_IP='<docker host ip>' -h <HOSTNAME> --privileged kernelci/lava-slave-docker:latest
Where LAVA_SERVER_IP is the IP of your Docker host. This allows the TFTP service to properly address the TFTP transfers.
In order for TFTP requests to find their way back to the running container, you will need to describe the host IP address to the LAVA master node. You can to create a yaml file on the LAVA master node as described below.
echo "dispatcher_ip: <dispatcher host ip" > /etc/lava-server/dispatcher.d/<lava-slave-hostname>.yaml
To use libguestfs for image overlays, access to the host kernel and modules must be provided. Typically this means that under /boot there exists a kernel with the naming convention below.
/boot/vmlinuz-<version>
