What service mode is used to deploy a single task of a service to a node?

A global service is a service that runs one task on every node. There is no pre-specified number of tasks. Each time you add a node to the swarm, the orchestrator creates a task and the scheduler assigns the task to the new node.

How do I deploy docker service?

Which command is used to create an overlay network that can be used with swarm services?

You can use overlay networks to connect one or more services within the swarm. First, create overlay network on a manager node using the docker network create command with the –driver overlay flag. After you create an overlay network in swarm mode, all manager nodes have access to the network.

How do I start a service in a Docker container?

Run Docker Container as a Service Docker team recommends to use cross-platform built-in restart policy for running container as a service.
