etcd not bootstrapping

[roberto-maggi]

Hi you all,
first time ho Kubernetes bare metal, first issue I can't solve...

I went through all the procedure , inso far..., and got stuck at the etcd bootstrapping.

first I got problems with the certificates, avoided to solve fast the problem because I'm working on my own laptop,

this is the leader etcd1 etcd.service

[Unit]
Description=etcd
Documentation=http://github.com/coreos
[Service]
ExecStart=/usr/bin/etcd --name etcd1
--initial-advertise-peer-urls http://10.240.0.12:2380
--listen-peer-urls http://10.240.0.12:2380
--listen-client-urls http://10.240.0.12:2379,http://127.0.0.1:2379
--advertise-client-urls http://10.240.0.12:2379
--initial-cluster-token etcd-cluster-0
--initial-cluster etcd1=http://10.240.0.12:2380,etcd2=http://10.240.0.100:2380
--initial-cluster-state new
--data-dir=/var/lib/etcd
--debug
Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target

here's the spare 2nd etcd

[Unit]
Description=etcd
Documentation=http://github.com/coreos
[Service]
ExecStart=/usr/bin/etcd --name etcd2
--initial-advertise-peer-urls http://10.240.0.100:2380
--listen-peer-urls http://10.240.0.100:2380
--listen-client-urls http://10.240.0.100:2379,http://127.0.0.1:2379
--advertise-client-urls http://10.240.0.100:2379
--initial-cluster-token etcd-cluster-0
--initial-cluster etcd1=http://10.240.0.12:2380,etcd2=http://10.240.0.100:2380
--initial-cluster-state new
--data-dir=/var/lib/etcd
--debug
Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target

as you can see the service rose apparently correctly
