Main Docker container orchestration tools include Docker Swarm, Kubernetes, and Nomad. Docker Swarm is Docker's native tool, simple and easy to use, suitable for small to medium-sized clusters; Kubernetes (K8s) is powerful with a complete ecosystem, suitable for large-scale production environments, but has a steep learning curve; Nomad is HashiCorp's lightweight orchestration tool that supports multiple workloads. Selection recommendations: small teams or simple applications choose Docker Swarm; need high availability, auto-scaling, service mesh and other advanced features choose Kubernetes; need hybrid orchestration (containers, virtual machines, etc.) consider Nomad. Kubernetes has become the de facto standard with an active community and extensive enterprise support.
