Docker Docker swarm mode
Introduction
A swarm is a number of Docker Engines (or nodes) that deploy services collectively. Swarm is used to distribute processing across many physical, virtual or cloud machines.
Syntax
-
Initialize a swarm: docker swarm init [OPTIONS]
-
Join a swarm as a node and/or manager: docker swarm join [OPTIONS] HOST:PORT
-
Create a new service: docker service create [OPTIONS] IMAGE [COMMAND] [ARG...]
-
Display detailed information on one or more services: docker service inspect [OPTIONS] SERVICE [SERVICE...]
-
List services: docker service ls [OPTIONS]
-
Remove one or more services: docker service rm SERVICE [SERVICE...]
-
Scale one or multiple replicated services: docker service scale SERVICE=REPLICAS [SERVICE=REPLICAS...]
-
List the tasks of one or more services: docker service ps [OPTIONS] SERVICE [SERVICE...]
-
Update a service: docker service update [OPTIONS] SERVICE
Remarks
Swarm mode implements the following features:
- Cluster management integrated with Docker Engine
- Decentralized design
- Declarative service model
- Scaling
- Desired state reconciliation
- Multi-host networking
- Service discovery
- Load balancing
- Secure design by default
- Rolling updates
