OpenShift の様々な操作で使用する oc コマンドにおいて、pod 関連で思いのほか面倒と思われるものを、使用例としてご紹介します。
Resources
$ oc explain pod.spec.containers.resources
KIND: Pod
VERSION: v1
FIELD: resources <ResourceRequirements>
DESCRIPTION:
Compute Resources required by this container. Cannot be updated. More info:
https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
ResourceRequirements describes the compute resource requirements.
FIELDS:
claims <[]ResourceClaim>
Claims lists the names of resources, defined in spec.resourceClaims, that
are used by this container.
This is an alpha field and requires enabling the DynamicResourceAllocation
feature gate.
This field is immutable. It can only be set for containers.
limits <map[string]Quantity>
Limits describes the maximum amount of compute resources allowed. More info:
https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
requests <map[string]Quantity>
Requests describes the minimum amount of compute resources required. If
Requests is omitted for a container, it defaults to Limits if that is
explicitly specified, otherwise to an implementation-defined value. Requests
cannot exceed Limits. More info:
https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/

Owner
$ oc explain pod.metadata.ownerReferences
KIND: Pod
VERSION: v1
FIELD: ownerReferences <[]OwnerReference>
DESCRIPTION:
List of objects depended by this object. If ALL objects in the list have
been deleted, this object will be garbage collected. If this object is
managed by a controller, then an entry in this list will point to this
controller, with the controller field set to true. There cannot be more than
one managing controller.
OwnerReference contains enough information to let you identify an owning
object. An owning object must be in the same namespace as the dependent, or
be cluster-scoped, so there is no namespace field.
FIELDS:
apiVersion <string> -required-
API version of the referent.
blockOwnerDeletion <boolean>
If true, AND if the owner has the "foregroundDeletion" finalizer, then the
owner cannot be deleted from the key-value store until this reference is
removed. See
https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion
for how the garbage collector interacts with this field and enforces the
foreground deletion. Defaults to false. To set this field, a user needs
"delete" permission of the owner, otherwise 422 (Unprocessable Entity) will
be returned.
controller <boolean>
If true, this reference points to the managing controller.
kind <string> -required-
Kind of the referent. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
name <string> -required-
Name of the referent. More info:
https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names
uid <string> -required-
UID of the referent. More info:
https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids

Hostname and IP Address
$ oc explain pod.status.spec.nodeName
KIND: Pod
VERSION: v1
error: field "nodeName" does not exist
$ oc explain pod.spec.nodeName
KIND: Pod
VERSION: v1
FIELD: nodeName <string>
DESCRIPTION:
NodeName is a request to schedule this pod onto a specific node. If it is
non-empty, the scheduler simply schedules this pod onto that node, assuming
that it fits resource requirements.
$ oc explain pod.status.hostIP
KIND: Pod
VERSION: v1
FIELD: hostIP <string>
DESCRIPTION:
hostIP holds the IP address of the host to which the pod is assigned. Empty
if the pod has not started yet. A pod can be assigned to a node that has a
problem in kubelet which in turns mean that HostIP will not be updated even
if there is a node is assigned to pod
$ oc explain pod.status.hostIPs
KIND: Pod
VERSION: v1
FIELD: hostIPs <[]HostIP>
DESCRIPTION:
hostIPs holds the IP addresses allocated to the host. If this field is
specified, the first entry must match the hostIP field. This list is empty
if the pod has not started yet. A pod can be assigned to a node that has a
problem in kubelet which in turns means that HostIPs will not be updated
even if there is a node is assigned to this pod.
HostIP represents a single IP address allocated to the host.
FIELDS:
ip <string>
IP is the IP address assigned to the host
$ oc explain pod.status.podIP
KIND: Pod
VERSION: v1
FIELD: podIP <string>
DESCRIPTION:
podIP address allocated to the pod. Routable at least within the cluster.
Empty if not yet allocated.
$ oc explain pod.status.podIPs
KIND: Pod
VERSION: v1
FIELD: podIPs <[]PodIP>
DESCRIPTION:
podIPs holds the IP addresses allocated to the pod. If this field is
specified, the 0th entry must match the podIP field. Pods may be allocated
at most 1 value for each of IPv4 and IPv6. This list is empty if no IPs have
been allocated yet.
PodIP represents a single IP address allocated to the pod.
FIELDS:
ip <string>
IP is the IP address assigned to the pod

may reject unrecognized values. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind <string>
Kind is a string value representing the REST resource this object
represents. Servers may infer this from the endpoint the client submits
requests to. Cannot be updated. In CamelCase. More info:

NetworkSpec is the top-level network configuration object.
status <Object>
NetworkStatus is detailed operator status, which is distilled up to the
Network clusteroperator object.
