docker service replicas remain 0/1 : <p>I am trying out docker swarm with 1.12 on my Mac. I started 3 VirtualBox VMs, created a swarm cluster of 3 all fine.</p>

<pre><code>docker@redis1:~$ docker node ls 
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
2h1m8equ5w5beetbq3go56ebl    redis3  Ready Active 
8xubu8g7pzjvo34qdtqxeqjlj    redis2  Ready Active Reachable 
cbi0lyekxmp0o09j5hx48u7vm *  redis1  Ready Active Leader
</code></pre>

<p>However, when I create a service, I see no errors yet replicas always displays 0/1:</p>

<pre><code>docker@redis1:~$ docker service create --replicas 1 --name hello ubuntu:latest /bin/bash
76kvrcvnz6kdhsmzmug6jgnjv
docker@redis1:~$ docker service ls
ID            NAME   REPLICAS  IMAGE          COMMAND
76kvrcvnz6kd  hello  0/1       ubuntu:latest  /bin/bash
docker@redis1:~$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
</code></pre>

<p>What could be the problem? Where do I look for logs?
Thanks!</p>
