If your etcd cluster is installed using etcdadm, you are likely to find
certification files in the path /etc/etcd/pki/
: ca.crt
, etcdctl-etcd-client.key
, etcdctl-etcd-client.crt
If your etcd cluster is the builtin etcd in one kubernetes cluster( using kubeadm),
you can find the same files in /etc/kubernetes/pki/etcd/
: ca.crt
, healthcheck-client.crt
, healthcheck-client.key
Because SslContextBuilder
only support a PKCS#8 private key file in PEM format, convert etcdctl-etcd-client.key
to etcdctl-etcd-client.key.pem
according
to netty SslContextBuilder doc
File cert = new File("ca.crt");
File keyCertChainFile = new File("etcdctl-etcd-client.crt");
File keyFile = new File("etcdctl-etcd-client.key.pem");
SslContext context = GrpcSslContexts.forClient()
.trustManager(cert)
.keyManager(keyCertChainFile, keyFile)
.build();
Client client = Client.builder()
.endpoints("https://10.168.168.66:2379")
.sslContext(context)
.build();
client.getClusterClient().listMember().get().getMembers().forEach(member -> {
logger.info("member: {}", member);
});
