Docker Swarm is a native clustering and scheduling tool for Docker containers. It turns a pool of Docker hosts into a single, virtual Docker host. This allows for easy scaling and management of containerized applications.
Initialize Swarm Mode:
docker swarm init
Add Nodes to the Swarm:
docker swarm join --token <token> <manager-ip>:<port>
Deploy Services:
docker service create --name <service-name> <image>
List Nodes:
docker node ls
List Services:
docker service ls
Scale Services:
docker service scale <service-name>=<replica-count>
Remove Nodes:
docker node rm <node-id>
Docker Swarm is a powerful tool for managing containerized applications in a production environment. By following best practices and regularly maintaining your swarm, you can ensure high availability and performance for your applications.
