台阶

docker-machine create --driver virtualbox swarm-1
docker-machine create --driver virtualbox swarm-2
docker-machine create --driver virtualbox swarm-3

eval $(docker-machine env swarm-1)
docker swarm init --advertise-addr $(docker-machine ip swarm-1)

docker-machine ssh swarm-2
docker swarm join <token> and IP

docker-machine ssh swarm-3
docker swarm join <token> and IP

docker node ls

请建议。

我遇到了同样的问题。 解决方法如下：

1） 通过运行：

sudo docker service ls

获取服务列表。 您应该看到您试图创建的服务（redisdb）

2） 获取列表中redisdb服务旁边显示的ID

3） 运行：

sudo docker服务rm ID

4） 现在再次尝试运行create命令

希望对您有所帮助

docker service ls的输出是什么？您好@johnharris85，docker service ls的输出是空的

docker service ls ID模式副本图像

docker network ls

？
