eBPF Lab

This is a lab environment with example code from the book Learning eBPF by Liz Rice: https://github.com/lizrice/learning-ebpf

Lab Environment

A packer configuration was created in the packer folder to build and configure a Centos 9 stream VM with:

Unfortunately, some blockers (broken functionality, missing features) were encountered pretty early in the eBPF learning process when using the pre-built software from the distribution repositories. Therefore, most recent components are built from the main branch with the idea of a reproducible lab environment.

The Packer build allows to reproduce and develop the Lab image. To create the qemu image with Packer:

cd packer
packer build libvirt-centos9.pkr.hcl

Setup and Connect to Lab VM

Configure location of qemu image:

qemuimg=output/centos9-20230512-132055/centos9-20230512-132055.qcow2

Create the KVM lab VM:

sudo virt-install --name ebpf-lab --description "eBPF Lab" \
 --osinfo=centos-stream9 --ram=4096 --vcpus=2 \
 --disk path=$qemuimg --boot hd --wait 0 --autostart

Create a sample ssh config:

domip=$(sudo virsh -q domifaddr ebpf-lab | awk '{print $4}' | cut -d/ -f 1)

cat << EOF > ssh-config
Host ebpf-lab
    HostName $domip
    User root
EOF

Connect to the VM with password root:

ssh ebpf-lab -F ssh-config

Usage

  • Work as the root user

Lab cleanup

Remove the VM and associated resource:

sudo virsh destroy ebpf-lab
sudo virsh undefine ebpf-lab
rm ssh-config
rm $qemuimg
