java - 在GKE集群中运行的Java应用程序如何以编程方式应用yaml文件？

Question

我在Google Kubernetes Engine集群上部署了Java应用程序。如何使该应用程序以编程方式应用Yaml？等同于

kubectl apply -f deployment.yaml

我遇到了这个客户端库，但是找不到说明如何实现它的文档的一部分。 https://github.com/googleapis/google-api-java-client-services/tree/master/clients/google-api-services-container/v1

编辑:

感谢Guillaume和Mickey的指导。我尝试了 Kubernetes Java Client library，但获得了“禁止”。请参见下面的代码和响应:

    @RequestMapping(value = "/list-pods", method = GET, produces = TEXT_PLAIN_VALUE)
    public String listPods() throws Exception {
        KubeConfig.registerAuthenticator(new GCPAuthenticator());
        final CoreV1Api api = new CoreV1Api(Config.defaultClient());
        V1PodList list = api.listPodForAllNamespaces(null, null, null, null, null, null, null, null, null);
        StringBuilder builder = new StringBuilder("Pods: \n\n");
        for (V1Pod item : list.getItems()) builder.append(item.getMetadata().getName());
        return builder.toString();
    }

这是抛出的异常:

我终于按照FL3SH的建议配置了必需的rbac使其工作了。 https://kubernetes.io/docs/reference/access-authn-authz/rbac/
