# K8s - [Kubernetes Attributes](#kubernetes-attributes) - [Deprecated Kubernetes Attributes](#deprecated-kubernetes-attributes) ## Kubernetes Attributes Kubernetes resource attributes. | Attribute | Type | Description | Examples | Stability | |---|---|---|---|---| | `k8s.cluster.name` | string | The name of the cluster. | `opentelemetry-cluster` |  | | `k8s.cluster.uid` | string | A pseudo-ID for the cluster, set to the UID of the `kube-system` namespace. [1] | `218fc5a9-a5f1-4b54-aa05-46717d0ab26d` |  | | `k8s.container.name` | string | The name of the Container from Pod specification, must be unique within a Pod. Container runtime usually uses different globally unique name (`container.name`). | `redis` |  | | `k8s.container.restart_count` | int | Number of times the container was restarted. This attribute can be used to identify a particular container (running or stopped) within a container spec. | |  | | `k8s.container.status.last_terminated_reason` | string | Last terminated reason of the Container. | `Evicted`; `Error` |  | | `k8s.cronjob.name` | string | The name of the CronJob. | `opentelemetry` |  | | `k8s.cronjob.uid` | string | The UID of the CronJob. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.daemonset.name` | string | The name of the DaemonSet. | `opentelemetry` |  | | `k8s.daemonset.uid` | string | The UID of the DaemonSet. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.deployment.name` | string | The name of the Deployment. | `opentelemetry` |  | | `k8s.deployment.uid` | string | The UID of the Deployment. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.job.name` | string | The name of the Job. | `opentelemetry` |  | | `k8s.job.uid` | string | The UID of the Job. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.namespace.name` | string | The name of the namespace that the pod is running in. | `default` |  | | `k8s.node.name` | string | The name of the Node. | `node-1` |  | | `k8s.node.uid` | string | The UID of the Node. | `1eb3a0c6-0477-4080-a9cb-0cb7db65c6a2` |  | | `k8s.pod.annotation.` | string | The annotation key-value pairs placed on the Pod, the `` being the annotation name, the value being the annotation value. | `k8s.pod.annotation.kubernetes.io/enforce-mountable-secrets=true`; `k8s.pod.annotation.mycompany.io/arch=x64`; `k8s.pod.annotation.data=` |  | | `k8s.pod.label.` | string | The label key-value pairs placed on the Pod, the `` being the label name, the value being the label value. | `k8s.pod.label.app=my-app`; `k8s.pod.label.mycompany.io/arch=x64`; `k8s.pod.label.data=` |  | | `k8s.pod.name` | string | The name of the Pod. | `opentelemetry-pod-autoconf` |  | | `k8s.pod.uid` | string | The UID of the Pod. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.replicaset.name` | string | The name of the ReplicaSet. | `opentelemetry` |  | | `k8s.replicaset.uid` | string | The UID of the ReplicaSet. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.statefulset.name` | string | The name of the StatefulSet. | `opentelemetry` |  | | `k8s.statefulset.uid` | string | The UID of the StatefulSet. | `275ecb36-5aa8-4c2a-9c47-d8bb681b9aff` |  | | `k8s.volume.name` | string | The name of the K8s volume. | `volume0` |  | | `k8s.volume.type` | string | The type of the K8s volume. | `emptyDir`; `persistentVolumeClaim` |  | **[1]:** K8s doesn't have support for obtaining a cluster ID. If this is ever added, we will recommend collecting the `k8s.cluster.uid` through the official APIs. In the meantime, we are able to use the `uid` of the `kube-system` namespace as a proxy for cluster ID. Read on for the rationale. Every object created in a K8s cluster is assigned a distinct UID. The `kube-system` namespace is used by Kubernetes itself and will exist for the lifetime of the cluster. Using the `uid` of the `kube-system` namespace is a reasonable proxy for the K8s ClusterID as it will only change if the cluster is rebuilt. Furthermore, Kubernetes UIDs are UUIDs as standardized by [ISO/IEC 9834-8 and ITU-T X.667](https://www.itu.int/ITU-T/studygroups/com17/oid.html). Which states: > If generated according to one of the mechanisms defined in Rec. > ITU-T X.667 | ISO/IEC 9834-8, a UUID is either guaranteed to be > different from all other UUIDs generated before 3603 A.D., or is > extremely likely to be different (depending on the mechanism chosen). Therefore, UIDs between clusters should be extremely unlikely to conflict. `k8s.volume.type` has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used. | Value | Description | Stability | |---|---|---| | `configMap` | A [configMap](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#configmap) volume |  | | `downwardAPI` | A [downwardAPI](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#downwardapi) volume |  | | `emptyDir` | An [emptyDir](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#emptydir) volume |  | | `local` | A [local](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#local) volume |  | | `persistentVolumeClaim` | A [persistentVolumeClaim](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#persistentvolumeclaim) volume |  | | `secret` | A [secret](https://v1-29.docs.kubernetes.io/docs/concepts/storage/volumes/#secret) volume |  | ## Deprecated Kubernetes Attributes Describes deprecated k8s attributes. | Attribute | Type | Description | Examples | Stability | |---|---|---|---|---| | `k8s.pod.labels.` | string | Deprecated, use `k8s.pod.label` instead. | `k8s.pod.label.app=my-app` |
