Demoting a node

You can demote any manager node to a worker node at any time. To demote a node, run the below command on the manager node-

$ docker node demote NODE

Example-

root@master:~# docker node ls
ID                            HOSTNAME   STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
buc72h0hyo66gcilq7melh9pq *   master     Ready     Active         Leader           20.10.11
xvdyauu8t83r3udrqh6c5w8a8     worker01   Ready     Active         Reachable        20.10.11
xctiaq0n14aew1falekqybq53     worker02   Ready     Active         Reachable        20.10.11

here all the node is manager node you can see in manager status. You can use node inspect command to check node status whether it's a manager or a worker node -

root@master:~# docker node demote worker01 worker02
Manager worker01 demoted in the swarm.
Manager worker02 demoted in the swarm.
root@master:~# docker node ls
ID                            HOSTNAME   STATUS    AVAILABILITY   MANAGER STATUS   ENGINE VERSION
buc72h0hyo66gcilq7melh9pq *   master     Ready     Active         Leader           20.10.11
xvdyauu8t83r3udrqh6c5w8a8     worker01   Ready     Active                          20.10.11
xctiaq0n14aew1falekqybq53     worker02   Ready     Active                          20.10.11
