This demonstrates using Cloudflare's [cfssl](https://github.com/cloudflare/cfssl) to easily generate certificates for an etcd cluster.
Defaults generate an ECDSA-384 root and leaf certificates for `localhost`. etcd nodes will use the same certificates for both sides of mutual authentication, but won't require client certs for non-peer clients.
**Instructions**
1. Install git, go, and make
2. Amend https://github.com/coreos/etcd/blob/master/hack/tls-setup/config/req-csr.json - IP's currently in the config should be replaced/added with IP addresses of each cluster node, please note 127.0.0.1 is always required for loopback purposes:
```json
Example:
{
"CN": "etcd",
"hosts": [
"3.8.121.201",
"46.4.19.20",
"127.0.0.1"
],
"key": {
"algo": "ecdsa",
"size": 384
},
"names": [
{
"O": "autogenerated",
"OU": "etcd cluster",
"L": "the internet"
}
]
}
```
3. Run `make` to generate the certs
