問題我正在嘗試使用gRPC. 我已獲得訪問kubernetes命名空間以測試客戶端的權(quán)限。但是，我所擁有的只是集群的證書頒發(fā)機構(gòu)和不記名令牌。apiVersion: v1clusters:- cluster:    certificate-authority: /etc/ssl/certs/devwat-dal13-cruiser15-ca-bundle.pem    server: https://<host-ip>:<port>  name: devwat-dal13-cruiser15contexts:- context:    cluster: devwat-dal13-cruiser15    namespace: interns    user: devwat-dal13-cruiser15-sa-interns-editor  name: devwat-dal13-cruiser15-internscurrent-context: devwat-dal13-cruiser15-internskind: Configpreferences: {}users:- name: devwat-dal13-cruiser15-sa-interns-editor  user:    token: <token>代碼我不太了解SSL和證書，但我嘗試按照在線使用Java的文檔進行操作SSL/TLS，gRPC并提出以下內(nèi)容：public class TrainerClient {    private ManagedChannel channel;    private TrainerGrpc.TrainerBlockingStub stub;    //private final String OVERRIDE_AUTHORITY = "24164dfe5c7842c98de431e53b6111d9-kubernetes-ca";    private final String CERT_FILE_PATH = Paths.get("/etc", "ssl", "certs", "devwat-dal13-cruiser15-ca-bundle.pem").toString();    private static final Logger logger = Logger.getLogger(TrainerClient.class.getName());    public TrainerClient(URL serviceUrl) {        File certFile = new File(CERT_FILE_PATH);        try {            logger.info("Initializing channel using SSL...");            this.channel = NettyChannelBuilder.forAddress(serviceUrl.getHost(), serviceUrl.getPort())                    //.overrideAuthority(OVERRIDE_AUTHORITY)                    .sslContext(getSslContext(certFile))                    .build();            logger.info("Initializing new blocking stub...");            this.stub = TrainerGrpc.newBlockingStub(channel);        } catch (Exception ex) {            logger.log(Level.SEVERE, "Channel build failed: {0}", ex.toString());            System.exit(1);        }    }該吊艙類型是ClusterIP與正被端口轉(zhuǎn)發(fā)到localhost與端口8443。
