Nginx Swarm：主机中的管理器+；VM中的工作进程：工作进程中没有容器

我正在尝试使用带有docker swarm的nginx容器部署CDN。 目前，我在主机中有一个manager，在VM上有一个worker，它是使用docker机器创建的：

pierpaolo@pierpaolo-Lenovo-G580:~$ docker-machine create -d virtualbox worker1

Docker version 1.12.5, build 7392c3b

然后，在worker1上，我运行：

docker@worker1:~$     docker swarm join \
>     --token SWMTKN-1-0tfvpvdlmugavn3fyqtjn9wkd3oeqze6nmw547shp07y73whix-4dqc40
4txwg58zibnz3lmp30w \
>     192.168.1.101:2377
This node joined a swarm as a worker.

在主机上，我创建了覆盖网络：

pierpaolo@pierpaolo-Lenovo-G580:~$ docker network create -d overlay mynetwork  
cb9plmvxn6twjt5lm7xgnq4ha

并创建了我的服务，共有10个副本：

docker service create --name nginx-cdn --network mynetwork --replicas 10 -p 9999:80 nginx-new:latest
dt1rfrix71cawpr8czzy4jje4

但是，如下所示：

pierpaolo@pierpaolo-Lenovo-G580:~$ docker service ls
ID            NAME       REPLICAS  IMAGE             COMMAND
dt1rfrix71ca  nginx-cdn  0/10      nginx-new:latest  

pierpaolo@pierpaolo-Lenovo-G580:~$ docker ps

在manager（主机）上，10个副本中只有5个副本，而在worker1上只有5个副本

docker@worker1:~$ docker ps --all
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

没有集装箱

为什么?

如果i cmd

docker服务ps nginx cdn

有以下几行：

ID                         NAME              IMAGE             NODE                   DESIRED STATE  CURRENT STATE                 ERROR

但是我创建了一个名为“nginx new:latest”的图像，如果我从该图像创建了一个容器，它就会工作。

您是否也将nginx new:latest图像移动到您的工作台上1？这张照片好像不见了。仅在本地计算机上拥有映像是不够的。你也可以创建你自己的私有注册表，把你的图像推到它上面，然后从你的工作人员那里拉出来作为例子（将来可能有用）。是的，我已经把我自己的图像推到hub上，现在它工作了。感谢您的支持。您是否也将nginx new:latest映像移到了您的worker1上？这张照片好像不见了。仅在本地计算机上拥有映像是不够的。你也可以创建你自己的私有注册表，把你的图像推到它上面，然后从你的工作人员那里拉出来作为例子（将来可能有用）。是的，我已经把我自己的图像推到hub上，现在它工作了。谢谢你的支持。
