This is an howto install a lava-docker slave This howto is based on a Debian host. Along with this file, you could see standalone-slave.yaml.example file. The rest of the document is based on that example.

Create a dedicated user

The user will be lavadocker in our example. It must be in the docker group for doing docker operations.

useradd -G docker lavadocker

Install all pre-requisites packages

docker-compose need to be installed from PIP

apt-get install git python-pip

Install docker-ce

See https://docs.docker.com/install/linux/docker-ce/debian/ for more detailled informations.

install docker-compose for our user

As lavadocker run:

pip install --user docker-compose

Install a second network interface

Having a dedicated network for boards is recommanded. Anyway, we will call enx0 the network card wired on the network connected to DUTs. (Whatever it is dedicated or not)

Install a DHCPD listenning on enx0

You need to have a DHCPD on the network where your boards are. You have many choices, for our examples we will use isc-dhcp-server:

apt-get install isc-dhcp-server

Configure the DHCPD server

sed -i 's,INTERFACESv4="",INTERFACESv4="enx0",' /etc/default/isc-dhcp-server

Add the following to /etc/dhcp/dhcpd.conf

subnet 192.168.66.0 netmask 255.255.255.0 {
  range 192.168.66.11 192.168.66.250;
	option routers 192.168.66.1;
}

The IP range is an example. You can use whatever you want BUT your need that enx0 to be in the same IP network. (network accessible from the IP given by DHCPD) In this example enx0 can be 192.168.66.1.

Checkout lava-docker sources

As lavadocker run:

git clone https://github.com/kernelci/lava-docker.git

Create your slave configuration file

Create your own file

Copy standalone-slave.yaml.example to standalone-slave.yaml

Get the following required values from the LAVA master administrator

  • A remote username (remote_user)
  • A remote token for this username (remote_user_token)
  • The FQDN for connecting to the master (remote_master)

In our standalone-slave.yaml it will be:

    remote_master: lava.example.com
    remote_user: lab-extern
    remote_user_token: lab-extern-randomtoken

Generate files

As lavadocker run:

./lavalab-gen.py standalone-slave.yaml

Run deploy.sh in the generated directory

cd output/externpc/
./deploy.sh

deploy.sh will

  • Deploy udev rules
  • Build images
  • Run the final images
