我要评论一、首先，要使用cfssl生成etcd证书相关的文件(ca.pem server.pem server-key.pem ),然后把server-key.pem进行转换：
openssl pkcs8 -topk8 -nocrypt -in server-key.pem -out server.key
二、带证书启动etcd
./etcd --name infra0 --cert-file=/root/server.pem --key-file=/root/server-key.pem --advertise-client-urls=https://0.0.0.0:2379 --listen-client-urls=https://0.0.0.0:2379
可通过etcdctl 进行连接验证
./etcdctl --cacert=/root/ca.pem --cert=/root/server.pem --key=/root/server-key.pem --endpoints="https://10.180.23.10:2379" get elon
三、在java项目中添加相关依赖，完整依赖类似如下：
<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/pom/4.0.0"
xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

四、创建客户端，访问etcd
package cn.edu.tju;
import io.etcd.jetcd.bytesequence;
import io.etcd.jetcd.client;
import io.etcd.jetcd.kv;
import io.etcd.jetcd.api.putresponse;
import io.grpc.netty.grpcsslcontexts;
import io.netty.handler.ssl.sslcontext;
import java.io.file;
import java.io.ioexception;
import java.util.concurrent.completablefuture;
import java.util.concurrent.executionexception;
public class etcdexample {
public static void main(string[] args) throws ioexception, executionexception, interruptedexception {
file cert = new file("d:\\ca.pem");
file keycertchainfile = new file("d:\\server.pem");
file keyfile = new file("d:\\server.key");
sslcontext context = grpcsslcontexts.forclient()
.trustmanager(cert)
.keymanager(keycertchainfile, keyfile)
.build();
client client = client.builder()
.endpoints("https://xx.xx.xx.xx:2379")
.sslcontext(context)
.build();
bytesequence key = bytesequence.from("elon".getbytes());
bytesequence value = bytesequence.from("musk".getbytes());
// put the key-value
client.getkvclient().put(key,value).get();
system.out.println("ok");
}
