410labs/promtail repository overview

⁠promtail

This is based on the official [grafana/promtail] image. All it does is add the command line argument -client.external-labes="#{EXTERNAL_LABELS}" so you can set labels via an environment variable.

E.g. in docker-compose.yml, used with docker swarm:

  promtail:
    image: "410labs/promtail"
    deploy:
      mode: global
    environment:
      EXTERNAL_LABELS: "host={{.Node.Hostname}}"
