Docker Docker swarm mode Node Availablility
Example
Swarm Mode Node Availability:
- Active means that the scheduler can assign tasks to a node.
- Pause means the scheduler doesn’t assign new tasks to the node, but existing tasks remain running.
- Drain means the scheduler doesn’t assign new tasks to the node. The scheduler shuts down any existing tasks and schedules them on an available node.
To change Mode Availability:
#Following commands can be used on swarm manager(s)
docker node update --availability drain node-1
#to verify:
docker node ls
