I am trying to install UCP master using the below command 

docker run --rm -i -v /var/run/docker.sock:/var/run/docker.sock --name ucp docker/ucp:1.0.3 install

However, I am getting the below error 

ERRO[0029] Failed to set up initial UCP configuration
FATA[0029] client: etcd cluster is unavailable or misconfigured

Why do I see that error?

As mentioned in "Node Discovery", make sure your docker daemon is launched with the --cluster-advertise option specifies the host:port or interface:port combination that this particular daemon instance should use when advertising itself to the cluster.

If not, you would see that error message (which comes from coreos/etcd/client/client.go)

  • I am trying to launch docker daemon with this command: `/usr/bin/docker daemon -D --cluster-advertise eth0:12376` but it doesn't seem to work – meallhour Apr 28 '16 at 16:03
  • @meallhour I don't see eth0 in https://docs.docker.com/engine/reference/commandline/daemon/#nodes-discovery – VonC Apr 28 '16 at 16:05
  • I ran this command: `docker daemon --cluster-advertise 10.211.144.177:2376` but getting error: `ERRO[0000] [graphdriver] prior storage driver "devicemapper" failed: devmapper: Base Device UUID and Filesystem verification failed.devicemapper: Error running deviceCreate (ActivateDevice) dm_task_run failed FATA[0000] Error starting daemon: error initializing graphdriver: devmapper: Base Device UUID and Filesystem verification failed.devicemapper: Error running deviceCreate (ActivateDevice) dm_task_run failed` – meallhour Apr 28 '16 at 16:16
  • @meallhour there are at least 3 different parameters for advertising a key-value store to a docker daemon. Why do you set-up only one? – VonC Apr 28 '16 at 16:21
  • How can i know path to `ca.pem` and `cert.pem` and `key.pem`? `"~/.docker/ca.pem" doesn't exist ` – meallhour Apr 28 '16 at 16:26
  • @meallhour That might be the issue: I have setup a key-value store *with* certificates: https://github.com/VonC/b2d/blob/bf94e41e909cc6d2e93b9f51991d997ad1448e38/nodes/kv/build#L27-L44 (here for boot2docker) – VonC Apr 28 '16 at 16:31
