[1.6] Single Node Host not working


#1

Specs: Virtualbox, Ubuntu 18.04

I’m trying to get 1.6 up and running on a single node server.

I’m using http:// so I don’t have to handle SSL

But I don’t seem to be able to get it working, even though rancher/server and rancher/agent are both up and running

I tried following this doc for Adding hosts to the same machine as rancher server
https://rancher.com/docs/rancher/v1.6/en/hosts/custom/#adding-hosts-to-the-same-machine-as-rancher-server

rancher/agent:

docker logs 1fbf9937a8f97f1d03ba7aba07f6babdd8ecff367c47268d8521f9fad7d07cc2 will show why it can’t be added

#4

The docs link you used say to specify the CATTLE_AGENT_IP when running the rancher/agent container but I don’t see that being used in your output.

$ sudo docker run -d -e CATTLE_AGENT_IP=<IP_OF_RANCHER_SERVER> -v /var/run/docker....

Also, can you indicate what is not working?


#5

I used:

docker run -d --restart=unless-stopped -e CATTLE_AGENT_IP=$(hostname --ip-address) -p 80:80 -p 8080:8080 -p 443:443 rancher/server

And then:

sudo docker run --rm --privileged -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/rancher:/var/lib/rancher rancher/agent:v1.2.11 http://10.10.10.139:8080/v1/scripts/552F5FC70BE3B1F9436D:1514678400000:p1fPVFSUiIv5umQlFvo8APdjYTg

The rancher/server and rancher/agent containers are running, but the host never gets added
