I am trying to run rancher to test it out and promote it with in my organization.
Here i have a multivm vagrant based setup. All the VMs are CentOS 7 (Linux host1 3.10.0-327.el7.x86_64 #1MP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux)

  1. One machine is dedicated to rancher.
  2. Two other machines are host1 and host2.
    Note: all these machines can ping each other and do ssh.
    I ran rancher in my rancher server box with following command:
    $ sudo docker run -d --restart=unless-stopped -p 8080:8080 rancher/server:stable
    This works fine i can see the UI and then when i try to add the host using this command

sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.2 http://rancher:8080/v1cripts/78651D3B0D78F77EF0B9:1483142400000:dIEJCGrcGbIKE0jHF7C3oU7bwOY
I see following output,

Not sure how to proceed from here. And do further debugging.

Only thing I can think of here is that rancher in your example is resolvable from the host but not within the container. Remember that the agent runs in a container which doesn’t have any /etc/hosts modifications that the host may have. Can you let me know if this helps?
