Features of Docker Swarm
The following are the features of Docker Swarm:
- Cluster management: To create Swarm you can use the Docker engine CLI where you can deploy the applications. Additional orchestration software is not required to manage a swarm.
- Multi-host networking: Swarm can contain multiple overlay networks so while deploying the service you can specify the network on which you want to deploy your service. The swarm manager automatically assigns addresses to the containers on the overlay network when it initializes or updates the application.
- Load balancing: While deploying any service on a particular port the swarm automatically balances the load of these ports.
- Scaling: When you scale up or down, the swarm manager automatically adapts by adding or removing tasks to maintain the desired state.
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without the need to manually restart the service Docker will update the configuration, stop the service tasks with the out-of-date configuration, and create new ones matching the desired configuration.
