Docker Swarm Setup

Swarm excels at operational simplicity. Factor reschedule time after node failure into your SLOs.

Topology

• Manager 3 / Worker 2+
• Overlay: separate ingress / internal networks
• Service replicas ≥ 2

deploy:
  replicas: 3
  update_config:
    parallelism: 1
    delay: 10s
    order: start-first
  restart_policy:
    condition: on-failure
