Swarm utils

About

Here are different tools I use throughout my Docker swarm

• 🐑Shepherd
• Swarm-cronjob
• Apprise
• prune-nodes : remove unused/exited tasks

Setup

version: '3.8'
 services:
  scheduler:
    image: crazymax/swarm-cronjob:latest

      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
      - 'TZ=Europe/Paris'
      - 'LOG_LEVEL=info'
      - 'LOG_JSON=false'
    deploy:
      placement:
        constraints:
          - node.role == manager

  prune-nodes:
    image: docker
    command: ['docker', 'system', 'prune', '--all', '--volumes' , '-f']
    volumes:
      - '/var/run/docker.sock:/var/run/docker.sock'
    deploy:
      mode: global
      labels:
        - swarm.cronjob.enable=true

        - swarm.cronjob.skip-running=true
      restart_policy:
        condition: none
