如何使用Fabric8 Java客户端获取kubernetes服务帐户访问令牌? [英] How to get kubernetes service account access token using fabric8 java client?

问题描述

我已经在本地计算机上配置了minikube，并将在外部使用kubernetes.我已经在kubernetes中创建了一个服务帐户，使用它的秘密，我可以使用以下命令获取访问令牌.

I have configured minikube in my local machine and going to use kubernetes externally. I have created a Service Account in kubernetes and using it's secret I can get the access token using below command.

kubectl get secret <service-account-secret> -o yaml -n mynamespace

我的问题是如何在运行时使用fabric8 Java客户端执行此操作?我想要的是通过提供服务帐户的机密作为参数来获取访问令牌.

My question is how can I do this using fabric8 java client in runtime ? What I want is to obtain the access token by giving the secret of the Service account as a parameter.

我正在以下面的方式启动配置.

I am initiating the config as bellow.

Config config = new ConfigBuilder().withMasterUrl(masterURL)
                .withClientCertFile(certFile).withOauthToken(serviceAccountAccessToken).build();

我可以知道如何使用fabric8 Java客户端获取如上所述的serviceAccountAccessToken吗?

Can I know how to get the serviceAccountAccessToken as described above using fabric8 java client ?

推荐答案

客户端已经为您完成了此任务.

The client already does that for you.

如果您仅创建一个空的Config对象:

If you just create an empty Config object:

Config config = new ConfigBuilder().build();

或创建客户端，例如:

KubernetesClient client = new DefaultKubernetesClient();

在容器中，它将自动为您读取令牌.

from within a pod, it will automatically read the token for you.

如果您需要将其传递给其他地方，则可以:

If you need to pass it elsewhere, you can just:

String token = config.getOauthToken();

或

String token = client.getConfiguration().getOauthToken();
