Datadog agent built from source for ARM 32-bit and 64-bit platforms (Raspberry Pi, Scaleway...)

TL;DR

ARM packages for the datadog-agent are available in the release page https://github.com/adrienkohlbecker/datadog-agent-arm/releases

If you don't trust the artifact that I built (realistically you probably shouldn't install a random deb in your infrastructure), instructions for a reproducible build are provided below. The build takes 3 hours but runs completely unattended.

Description

This uses a Scaleway C1 instance (bare-metal armv7 box), or a ARM64-2GB instance (bare-metal armv8 box) to compile and package a datadog-agent deb as close to the official amd64 release as possible.

Using a scaleway box means you can benefit from their SSD volumes and avoid cloning hundreds of source code repos and thousands of small files on your pi's sd card, which would take ages. It also makes the build process easily reproducible and self-contained, and avoids cluttering your pi with build dependencies.

You get as output a .deb file aimed to be as close as possible to the official release (comes with configs, systemd units, ...)

At the time of writing the agent release was 6.15.0, which is what this was tested with.

Known issues

• (armv7/armhf) The trace agent makes heavy use of atomic.*Int64 class of functions, which all panic on 32 bits architectures. I was able to fix the process agent here DataDog/datadog-process-agent#198 but for trace I think somebody from Datadog would be better equipped to make the right choices, given the amount of call sites.
• The aerospike and ibm_mq don't build on ARM and are thus blacklisted.
• The python3 runtime is disabled because of an issue with the build: Could not fetch URL https://pypi.org/simple/wheel/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/wheel/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

Patches

We apply patches from the following PRs, pending an official release:

• DataDog/datadog-agent#4377: Build system-probe from the agent omnibus recipe

How to use:

# install scaleway cli
$ brew install scw

# login to scaleway
$ scw login

# clone the gist
$ git clone https://github.com/adrienkohlbecker/datadog-agent-arm.git
$ cd datadog-agent-arm

# run the build for armv7/armhf
$ ./run.sh armhf

# run the build for armv8/arm64
$ ./run.sh arm64

# this will leave a .deb in the current directory
$ find . -name "*.deb"
