Swarm failed just after creation

Docker for Azure

Expected behavior

Having a swarm up and running once deployed on azure

Actual behavior

When ssh in my cluster, I get the following message:
swarm-manager000000:~$ docker node ls
Error response from daemon: This node is not a swarm manager. Use “docker swarm init” or “docker swarm join” to connect this node to swarm and try again.

Additional Information

Steps to reproduce the behavior

  1. follow this guide: https://beta.docker.com/docs/azure/
  2. SSH on manager. run docker node ls

Thanks @kapptivate,

Could you please run docker-diagnose and provide the ID associated with the diagnostics run?

here is the output:

Thanks @kapptivate. We will need some more data from your setup. Can you share the output of the command docker logs $(docker ps --filter name=init-azure) ? Please post the output log to https://gist.github.com/ and send us the URL at docker-for-iaas@docker.com if that works for you.

It seems there is no real logs on the machine (the init-azure container is not present)

Can you try docker logs $(docker ps -a | grep init-azure | cut -d' ' -f1) please? The init container doesnot show up in regular docker ps output since it exits after some init tasks.

Thanks.

I just sent you the logs to your email address.

I am also having the same issues. Any resolution on this?

@k1ck3rtw the earlier issue resulted from incorrect SP credentials passed to the ARM template. What failure are you seeing? Does docker node ls work successfully from the master nodes?

This issue has been resolved. The problem was when running
"docker4x/create-sp-azure", it would use my default Azure resource group
even if I explicitly selected a different resource group. After mentioning
this in forums, the image was updated in docker hub to not do this.
