Docker Swarm: The good, the bad and the ugly

Docker Swarm is an opinionated, easy to operate container orchestration tool. Docker swarm often gets overlooked but is an excellent solution for small teams. This talk we'll go through the process and pain points of setting up a productoin grade docker swarm cluster. The talk's index:

  • Quick intro: docker & orchestrators (problem statement)
  • Build-in features (the good):
    • High availability (Managers, Workers, Leader elections)
    • Load balancing methodologies
    • Service discovery
    • Secrets & Configuration management
    • Security (apparmor, seccomp profiles)
  • Problems that need to be solved in-house (the bad):
    • The init process: using a distributed lock to avoid race conditions
    • Auto-registration: traefik or nginx + confd
    • Auto-scaling at node level
    • Auto-scaling at service level
    • Disaster recovery
  • Missing Features (the ugly)
  • Q & A session
