Docker Swarm Node
When should I Use Docker Swarm?
Docker Swarm used be for simple, native Docker Orchestration purpose. It facilitates with easy setup and management for container clustering.
What is Swarm mode in docker?
The Swarm mode in Docker is a native clustering and orchestrating feature that enables the deployment, management and scaling of the containers across a cluster of docker hosts.
Why docker swarm mode is deprecated?
The Docker Swarm mode is deprecated because of kuberentes and it has become the more widely adopted and strong container orchestration platform leading to shift in focus and support.
What is docker swarm mode ingress?
Docker Swarm mode ingres is a built-in load balancing features that routes the incoming traffic to the appropriate service across the swarm cluster.
Is Docker Swarm Used in Production?
Yes Docker Swarm is used in the production environments but it is not much used as the kubernetes in the production environment. Kubernetes had more advantages then the docker swarm.
Is Docker Swarm Free?
Yes Docker swarm is free to use. You can run the docker swarm on as many as docker engine instances as you want without incurring any licensing costs.
What Ports are Used by Docker Swarm?
- TCP Port for the manager node: 2377
- Worker node TCP port: 2376
Is Docker Swarm a Load Balancer?
Docker swarm itself isn’t a full-fledged load balancer but you can achieve this by using two mechanisms.
- Overlay routing mesh
- Ingress
Introduction to Docker Swarm Mode
Docker swarm is a container orchestration tool. Swarm Mode in Docker was introduced in version 1.12 which enables the ability to deploy multiple containers on multiple Docker hosts. For this Docker uses an overlay network for the service discovery and with a built-in load balancer for scaling the services. One of the key advantages of docker swarm is that the configuration of the docker services such as volume and network can be modified without the need to manually restart the service Docker will update the configuration, stop the service tasks with the out-of-date configuration, and create new ones matching the desired configuration.
