“docker run swarm create” failed with error “503 Service Unavailable”
Question
My platform is :
- OS:
Ubuntu-16.04 - Docker version:
1.12.6, build 78d1802
When I ran docker run swarm create , it failed with following output:
Unable to find image 'swarm:latest' locally
latest: Pulling from library/swarm
ebe0176dcf9a: Pull complete
19f771faa982: Pull complete

Digest: sha256:815fc8fd4617d866e1256999c2c0a55cc8f377f3dade26c3edde3f0543a70c04
Status: Downloaded newer image for swarm:latest
<html><body><h1>**503 Service Unavailable**</h1>
**No server is available to handle this request.**
</body></html>
I was doing POC on swarm to orchestrate different docker containers but not able to proceed. Please help in resolving this issue.

The might be some confusion in what you've done.
docker run swarm create is not how you can create a swarm cluster with docker 1.12+.
I don't know precisely what the library/swarm container is for, but definitely not for operating a swarm cluster (maybe an old way for it?).
The command to create a swarm cluster with Docker version 1.12+, on your manager node, is :
docker swarm init --advertise-addr <MANAGER-IP>
You can have a look at this official docker swarm tutorial to do your POC.
