Trouble starting rancher/agent with cloud-init

Archive RancherOS
1

Launching EC2 instance.
RancherOS v0.4.1
Rancher Server v0.49.1

Has anyone been able to start a rancher/agent on ROS startup using cloud-config like this:

#cloud-config
rancher:
  services:
    rancher-agent:
      image: rancher/agent:latest
      command: http://<rancher-server-ip>:8080/v1/projects/1a5/scripts/<registrationToken>
      privileged: true
      volumes:
        - /var/run/docker.sock:/var/run/docker.sock

following this example.

I can see the container start then it immediately gets terminated.

$ cat /var/log/docker.log

You cannot label the service as rancher-agent and then it will work. Also, you should use the specific rancher/agent version that is pinned with the release. You can find it when you look at the “Add Custom Host” command.

So if you change it to

#cloud-config
rancher:
  services:
    rancher-agent1:
      image: rancher/agent:v0.8.2
      command: http://<rancher-server-ip>:8080/v1/projects/1a5/scripts/<registrationToken>
      privileged: true
      volumes:
        - /var/run/docker.sock:/var/run/docker.sock
