I’m using RHEL 7.1, iptables (not firewalld), CS Docker Engine 1.11.2-cs4. UCP installs fine and then I successfully join three additional nodes, one which will be the DTR.
I then run the install command to install:
docker run -it --rm \ docker/dtr install \ --ucp-url https://UCP_HOSTNAME \ --ucp-node DTR_NODENAME \ --dtr-external-url DTR_IP \ --ucp-username admin \ --ucp-password SECRET_PWD \ --ucp-ca "$(cat ucp-ca.pem)"
The main error I get is:
INFO Waiting for etcd DEBU Failed to connect to etcd: error #0: dial tcp: lookup dtr-etcd-72e0dd376179.dtr-br on 10.2.16.3:53: no such host;
I’m not able to copy/paste from my target system to get a larger output.
Basically, it tries this connection 40 times (every 500ms), then quits with:
ERRO Couldn't set up kvStore ... client: etcd cluster unavailable or misconfigured
I’ve searched everywhere can’t find details on what would resolve. I’m about to move to Ubuntu 14.04 LTS to see if that helps. I’ve tried the entire setup with Docker Engine 1.12.1 with the same results.
Thanks for any help.
