RIPE Atlas Docker Image

This is the RIPE Atlas software probe packaged as a Docker image.

Requirements

• 1 CPU core (of course)
• 20MiB memory
• 100MiB HDD
• A Linux installation with Docker installed
• Internet access

Tags

The following prebuilt tags are available at Docker Hub:

• latest: For arm64 (x86_64) devices
• latest-armv7l: For armv7l (armhf) devices, e.g. Raspberry Pi (CI donated by @OtakuNekoP)

Running

First we start the container:

docker run --detach --restart=always --log-opt max-size=10m \
	--cpus=1 --memory=64m --memory-reservation=64m \
	--cap-add=SYS_ADMIN --cap-add=NET_RAW --cap-add=CHOWN \
	--mount type=tmpfs,destination=/var/atlasdata,tmpfs-size=64M \
	-v /var/atlas-probe/etc:/var/atlas-probe/etc \
	-v /var/atlas-probe/status:/var/atlas-probe/status \
	-e RXTXRPT=yes \
	--name ripe-atlas --hostname "$(hostname --fqdn)" \
	jamesits/ripe-atlas:latest

Then we fetch the generated public key:

cat /var/atlas-probe/etc/probe_key.pub

Register the probe with your public key. After the registration being manually processed, you'll see your new probe in your account.

Caveats

IPv6

Docker's IPv6 support is still like shit. As a workaround, you can use IPv6 NAT like this:

cat > /etc/sysctl.d/50-docker-ipv6.conf <<EOF
net.ipv6.conf.eth0.accept_ra=2
net.ipv6.conf.all.forwarding=1
net.ipv6.conf.default.forwarding=1
EOF
sysctl -p /etc/sysctl.d/50-docker-ipv6.conf
docker network create --ipv6 --subnet=fd00:a1a3::/48 ripe-atlas-network
docker run -d --restart=always -v /var/run/docker.sock:/var/run/docker.sock:ro -v /lib/modules:/lib/modules:ro --cap-drop=ALL --cap-add=NET_RAW --cap-add=NET_ADMIN --cap-add=SYS_MODULE --net=host --name=ipv6nat robbertkl/ipv6nat:latest

Then start the RIPE Atlas container with argument --net=ripe-atlas-network.

Note this might break your network and your mileage may vary. You should swap eth0 with your primary network adapter name, and if you use static IPv6 assignment instead of SLAAC, change accept_ra to 0.

Auto Update

Use this recipe for auto updating the docker container.

docker run -d -v /var/run/docker.sock:/var/run/docker.sock --name watchtower containrrr/watchtower --cleanup --label-enable

Then start the RIPE Atlas container with argument --label=com.centurylinklabs.watchtower.enable=true.

Backup

All the config files are stored at /var/atlas-probe. Just backup it.
