After you create a StatefulSet
object, you can request information about it
and its managed resources.
Before you begin
To run commands against a Kubernetes cluster, ensure you have the following resources:
Locate the Kubernetes cluster name, or ask your Platform Administrator what the cluster name is.
Sign in and generate the kubeconfig file for the Kubernetes cluster if you don't have one.
Use the kubeconfig path of the Kubernetes cluster to replace
KUBERNETES_CLUSTER_KUBECONFIG
in these instructions.
To get the required permissions to view all workloads deployed in a project, ask
your Organization IAM Admin to grant you the Workload Viewer role
(workload-viewer
) in your project namespace.
To get the required permissions to inspect stateful workloads, ask your
Organization IAM Admin to grant you the Namespace Admin role (namespace-admin
)
in your project namespace.
View a project's container workloads
To view your project's container workloads, complete the following:
Console
In the navigation menu, select Kubernetes Engine > Workloads.
You can view details for your container workloads, such as the following:
- Name
- Type
- Number of pods
- Kubernetes cluster
- Last modified date
The container workloads are organized by which Kubernetes cluster they belong to. Select the Cluster drop-down to switch the cluster context.
CLI
Run the following command to list all pods in your project:
kubectl get pods -n PROJECT_NAMESPACE
The output is similar to the following:
NAME READY STATUS RESTARTS AGE nginx-workload-ah-aa-1228 1/1 Running 0 12h nginx-workload-ah-ab-6784 1/1 Running 0 11h nginx-workload-ah-ac-0045 1/1 Running 0 12h
Inspect a StatefulSet
resource
To request more detailed information about the components of a StatefulSet
resource, run commands that directly target the entity you're looking to
inspect.
Get StatefulSet
object information
To get detailed information about the StatefulSet
object, run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
describe statefulset STATEFULSET_NAME
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running theStatefulSet
object.NAMESPACE
: the project namespace.STATEFULSET_NAME
: the name of theStatefulSet
object.
Display live configuration in YAML format
To display the live configuration of the StatefulSet
resource in YAML format,
run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
get statefulset STATEFULSET_NAME -o yaml
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running theStatefulSet
object.NAMESPACE
: the project namespace.STATEFULSET_NAME
: the name of theStatefulSet
object.
List pods
To list the Pod
objects created by the StatefulSet
, run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
get pods -l app=APP_NAME
In this command, the -l
flag lists all Pod
objects labeled with
APP_NAME
.
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running theStatefulSet
object.NAMESPACE
: the project namespace.APP_NAME
: the name of the stateful application managed by theStatefulSet
object.
Get specific pod information
To get information about a specific Pod
in the cluster, run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
describe pod POD_NAME
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running the pod.NAMESPACE
: the project namespace.POD_NAME
: the name of the pod managed by theStatefulSet
object.
List PVCs
To list the PersistentVolumeClaim
(PVC) objects in the cluster, run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
get pvc
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file of the cluster running the PVCs.NAMESPACE
: the project namespace.
Get specific PVC information
To get information about a specific PersistentVolumeClaim
(PVC) in the
cluster, run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
describe pvc PVC_NAME
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running the PVC.NAMESPACE
: the project namespace.PVC_NAME
: the name of the PVC configured for theStatefulSet
object.
Get PV information
To get information about a specific PersistentVolume
(PV) in the cluster,
run:
kubectl --kubeconfig KUBERNETES_CLUSTER_KUBECONFIG -n NAMESPACE \
describe pv PV_NAME
Replace the following:
KUBERNETES_CLUSTER_KUBECONFIG
: the kubeconfig file for the cluster running the PV.NAMESPACE
: the project namespace.PV_NAME
: the name of the PV configured for theStatefulSet
object.
