Error response from daemon: rpc error: code =
FailedPrecondition
删除docker swarm下的节点报错:
Error response from daemon: rpc error: code = FailedPrecondition desc = node y2qsyjdbfmm4tjwh4p9wqlmq1 is
not down and can’t be removed
解决(需要把active状态的节点的docker服务关闭;同时在manager节点中修改掉该节点的AVAILABILITY状态):
[vagrant@centos-node2 ~]$ sudo service docker stop
Redirecting to /bin/systemctl stop docker.service
[vagrant@centos-node1 ~]$ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS ENGINE VERSION
875ul8zt886yee5bp115xevpe * centos-node1 Ready Active Leader 19.03.5
y2qsyjdbfmm4tjwh4p9wqlmq1 centos-node2 Down Active 19.03.5
[vagrant@centos-node1 ~]$ docker node update --help
[vagrant@centos-node1 ~]$ docker node update --availability drain y2qsyjdbfmm4tjwh4p9wqlmq1
[vagrant@centos-node1 ~]$ docker node rm y2qsyjdbfmm4tjwh4p9wqlmq1
