只在miji0qamdnvkrinj009qa77yy 上运行portainer:
docker service create \
--name portainer \
--publish 9000:9000 \
--constraint 'node.id == miji0qamdnvkrinj009qa77yy' \
--mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock \
--mount type=bind,src=/data/portainer/data,dst=/data \
docker.ifeng.com/portainer/portainer \
-H unix:///var/run/docker.sock
其他约束用法：
--constraint 'node.id == asdfasdfadf'
--constraint 'node.role != manager'
--constraint 'node.hostname == node-1'
--constraint 'node.labels.type == database'
