No Access Token when running inside cluster?

[HenrikDK]

Hi

I'm using the C# client to fetch information from api server.

I decided to only partially use the client library to fetch "access token" that you need to attach as a bearer when making api requests.

While the approach worked fine while testing locally all requests started failing when the pod ran inside the cluster.

I added some logging so I could see what's happening inside the cluster:

if (KubernetesClientConfiguration.IsInCluster()){
    Log.Logger.Information($"Controller running in cluster with host \"{config.Host}\" using access token \"{config.AccessToken}\"");
    Log.Logger.Information(JsonConvert.SerializeObject(config));
}

When I run my pod inside a cluster the access token property is empty. And I get following message:

{"Timestamp":"2022-05-27T11:05:38.3458927+00:00","Level":"Information","MessageTemplate":"Controller running in cluster with host \"https://172.18.0.1:443/\" using access token \"\""}

Does the client use some other authentication method when running inside the cluster?

you can get token from /var/run/secrets/kubernetes.io/serviceaccount/token

the client will load token from the file above automatically
the config.token is for you to see static token and will not be populated
