是否可以使用docker swarm分配特定节点来创建容器？

Question

When creating new containers, it follows the swarm's strategy to select a node

I don't want to issue the command against the node directly if it have to work on that specific one.

Is there a way to tell swarm to work on a specific node?

UPDATE

According to @DAXaholic 's reply, by default daemon option Lable can be the callable tag.

So, I edit /etc/default/docker , add --label to DOCKER_OPTS .

After restart services, node is able to called by specific label values.

Yes you can do that with filters
So the idea is essentially you give your nodes tags that describe them like 'node-with-gpu' or something like that.
There is also a default tag 'node' which you can use to filter for a specific node

So an example to run Redis on node1 could look like this

$ docker tcp://<manager_ip:manager_port> run -d --name redis1 -e
constraint:node==node1 redis
