Dockerd exporter

Prometheus exporter for Docker daemon metrics. Inspired by https://github.com/stefanprodan/swarmprom

Requirements

You must enable Docker metrics-addr in all Swarm nodes.

Edit /etc/docker/daemon.json to add "metrics-addr": "0.0.0.0:9323" property:

Note: if your nodes are using Docker with version < v20.10, you must add experimental: true property too.

Don't forget to restart Docker daemon with systemctl restart docker (do it for every Swarm node).
