How to Set Up Docker Swarm for Container Orchestration

Docker Swarm provides container orchestration built into Docker — deploy services across multiple servers with automatic load balancing and failover.

Initialize Swarm

docker swarm init --advertise-addr MANAGER_IP
docker swarm join-token worker  # Run on workers

Deploy Service

docker service create --name web --replicas 3 --publish 80:80 nginx
docker service ls

Deploy Stack

docker stack deploy -c docker-stack.yml myapp

Rolling Update

docker service update --image nginx:latest --update-parallelism 1 --update-delay 10s web

Conclusion

Docker Swarm provides orchestration with minimal complexity. Our team deploys Docker Swarm infrastructure for production environments.
