ripe-atlas-sw-probe-packer

Create a RIPE ATLAS software probe using packer for Raspberry PI

Introduction

This packer is based on the packer builder script for Raspberry PI.

Then, I follow the steps included for Debian in the RIPE Atlas software documentation

Preparing the environment

Install dependencies

Install the packages in the host system, for example, for Debian/Ubuntu:

sudo apt-get install git unzip qemu-user-static e2fsprogs dosfstools

Install Packer

Install Packer. I use the official Packer, because the included in Debian is not working fine. You can download the latest version from https://releases.hashicorp.com/packer/

Download it, save, unzip and copy the binary to /usr/local/bin.

sudo mv packer /usr/local/bin/

Install packer-builder-arm

Now install packer-builder-arm, that is a program to build images for ARM.

You can download using git:

git clone https://github.com/mkaczanowski/packer-builder-arm

Now, build it using go:

cd packer-builder-arm
go mod download
go build

Copy the binary packer-builder-arm to the same place of packer, for example /usr/local/bin:

sudo cp packer-builder-arm /usr/local/bin/

Build the Atlas image

Download this code and run packer:

git clone https://github.com/thekix/ripe-atlas-sw-probe-packer.git
cd ripe-atlas-sw-probe-packer
sudo packer build ripe-atlas-sw-probe-packer.json

NOTE: If you have problems with the Packer builder about binmfts and the qemu-arm-static related execution, try this:

sudo update-binfmts --package qemu-user-static --install qemu-arm /usr/bin/qemu-arm-static --magic "\x7f\x45\x4c\x46\x01\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x28\x00" --mask "\xff\xff\xff\xff\xff\xff\xff\x00\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff\xff" --offset 0 --credential yes  --fix-binary yes

After the build, you will have the new image ripe-atlas-sw-probe.img Copy the image with dd to you SD card. Is something like:

dd if=ripe-atlas-sw-probe.img of=/dev/yourSDcard

First startup

In the first startup the script will connect with RIPE Atlas infrastructure and will generate the keys. The public key is stored in /var/atlas-probe/etc/probe_key.pub.

Register your probe at https://atlas.ripe.net/apply/swprobe/

NOTE: The file /etc/rc.local contains the script for this first startup. If you want, you can edit the file and remove the line about Atlas.
