The output reflects that there is a single pod, however it has two containers in it: NAME READY STATUS RESTARTS AGE If you’re trying to diagnose an issue with your app in Kubernetes, you’ll probably want to look at curl. It’s a handy tool for testing APIs and network requests. V1PodList list = api . listPodForAllNamespaces ( null , null , null , null , null , null , null , null , null ); System . out . println ( "Listing all pods: " ); for (V1Pod item : list . getItems ()) { System . out . println (item . getMetadata (). getName ()); } } } dotnet client Or prevent curl from uploading data faster than 1 megabyte per second: curl -T upload --limit-rate 1M ftp://uploads.example.com

Forcing curl not to transfer data faster than a given rate is also possible, which might be useful if you are using a limited bandwidth connection and you do not want your transfer to use all of it (sometimes referred to as bandwidth throttle). Upload a local file to get appended to the remote file: curl -T localfile -a ftp://ftp.example.com/remotefileI0304 12:47:59.697325 3573879 round_trippers.go:443] GET https://127.0.0.1:44291/api/v1/namespaces/kube-system/pods/kube-apiserver-kind-control-plane 200 OK in 5 milliseconds If you can’t get any of these images, because you’re perhaps running a cluster which is closed off from the internet, then you could try one of these instead: Unlike the apparently unprotected /version endpoint, Kubernetes generally restricts access to its API endpoints. Or automatically URL encode the data. curl --data-urlencode "name=Rafael Sagula&phone=3320780" http://www.example.com/guest.cgi

There are plenty of reasons to call the Kubernetes API using a CLI (like curl) or GUI (like postman) HTTP client. For instance, you may need finer-grained control over Kubernetes Objects than kubectl provides or just want to explore the API before trying to access it from code. A probe is a diagnostic performed periodically by the kubelet on a container. To perform a diagnostic, the kubelet can invoke different actions: Kubernetes does not have objects which represent users. I.e., users cannot be added to a cluster through an API call. However, any user that presents a valid certificate signed by the cluster's Certificate Authority is considered authenticated. Kubernetes takes the username from the common name field in the cert's subject (e.g., CN = minikube-user). Then, the Kubernetes RBAC sub-system determines whether the user is authorized to perform a specific operation on a resource.String kubeConfigPath = "~/.kube/config" ; // loading the out-of-cluster config, a kubeconfig from file-system ApiClient client = ClientBuilder . kubeconfig (KubeConfig . loadKubeConfig ( new FileReader (kubeConfigPath ))). build (); // set the global default api-client to the in-cluster one from above
