Getting failure when adding EC2 Host

Rancher 1.x
1

I’m attempting to add an “Amazon EC2” host. It seems to create the instance and connect to it, and gets a fair ways into provisioning it. It errors out with the status “Failed to find rancher-agent container”. At that point, I see this exception in the logs:

Can anyone tell me where to go from here? Should I just set up hosts with “Custom” provisioning?

I’ve gone on and manually created a couple of hosts. It’s so darn easy that I realize now that it doesn’t make much difference if I do it this way. In fact, this way, I can run Centos 7, which I’m more familiar with. I followed the instructions for the Generic host addition, and my hosts popped right up on the Hosts screen looking healthy.

So while launching hosts via AWS is snot something I figured out how to make work, I no longer really care that I didn’t.

I face the same issue, and I have resolved it.

  1. Add the DNS record
  2. Set the Host Registration URL as http://rancher.xxx.com:8080.
  3. Run the docker run in the new host.
$ sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.5 http://rancher.xxx.com:8080/v1/scripts/xxxxx:yyyyyyyyyy
