## Peers
## Endpoint
If your etcd cluster isn't available on `http://127.0.0.1:2379` you can specify
a `--peers` flag or `ETCDCTL_PEERS` environment variable. You can list one peer,
or a comma-separated list of peers. This option is ignored if the `--discovery-srv`
a `--endpoint` flag or `ETCDCTL_ENDPOINT` environment variable. You can list one endpoint,
or a comma-separated list of endpoints. This option is ignored if the `--discovery-srv`
option is provided.

## DNS Discovery
If you want to discover your etcd cluster through domain SRV records you can specify
a `--discovery-srv` flag or `ETCDCTL_DISCOVERY_SRV` environment variable. This option takes
