Can't add custom agent running on same node as rancher server

Rancher 1.x
1

I am trying to register a new host on the same host that also runs the rancher server, but can’t seem to get this to work. This registers fine on other nodes not running rancher server.

Any advise on what the issue may be would be great.

The Command I am using

sudo docker run -e CATTLE_SCRIPT_DEBUG=true -e CATTLE_AGENT_IP=192.168.8.100 -e CATTLE_HOST_LABELS='type=appserver' -d --privileged -v /var/run/docker.sock:/var/run/docker.sock rancher/agent:v0.8.2 http://192.168.8.100:8383/v1/scripts/D2331A0EFD36353BF956:1450360800000:2zDSKabLQ0He5vI0DOTiN9l3Is

The Output

Are you trying to use something locally using VirtualBox? There are a couple of similar Github issues, but I haven’t had time to test it out.

I never have any issues when I’m trying to add a host on the same node as rancher server when using a host from a cloud provider, so I think it’s something to do when running locally.


3

Yes I am running locally with virtualbox.

4

Can you actually see the UI when you go to http://192.168.8.100:8383?

How did you launch Rancher server command?

5

Yes I can see rancher UI running on http://192.168.8.100:8383. The only issue is trying to register an agent on same rancher server node.

I launched rancher server with this command

docker run --name=rancher-server -l io.rancher.container.system=rancher-agent --restart=always -d -p 8383:8080 rancher/server
6

Can you try launching a custom agent on a different VM instead of using the same one as rancher server? Does that one work?

7

This registers fine on other nodes not running rancher server

8

Looks like a regression :

I previously successfully installed the agent on the same host on 2015/10/15 (in Debian 8 Jessie), using Virtualbox.

Today, I’m trying a fresh install (in Ubuntu 14 Trusty) also in Virtualbox : impossible to get the host to be detected, even with the IP in parameter as indicated in the faqs on hosts (http://docs.rancher.com/rancher/faqs/hosts/) and in the docs on custom hosts (http://docs.rancher.com/rancher/rancher-ui/infrastructure/hosts/custom/#adding-hosts-to-the-same-machine-as-rancher-server)

See also : https://github.com/rancher/rancher/issues/872 ?

I wonder if the issue could be with this line item of rancher-server.

Have you tried launching racnher-server without that label and then trying to add it as a host? Is there a reason why you have added that label onto the rancher/server command?
