61. What are the features of Docker Swarm?
Some of the key features of Docker Swarm are as follows:
I. Compatible : Docker Swarm is compatible with standard Docker API.
II. High Scalability : Swarm can scale up to as much as 1000 nodes and 50000 containers. There is almost no
performance degradation at this scale in Docker Swarm.
III. Networking : Swarm comes with support for Docker Networking.
IV. High Availability : We can create a highly available system with Docker Swarm. It allows use to create
multiple master nodes so that in case of a failure, another node can take over.
V. Node Discovery : In Docker Swarm, we can add more nodes and the new nodes can be found with any
discovery service like etcd or zookeeper etc.
