initContainers ([]
Patch strategy: merge on key
name
List of initialization containers belonging to the pod. Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

Scheduling
-
nodeSelector (map[string]string)
NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/
-
nodeName (string)
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.

-
-
tolerations ([]Toleration)
If specified, the pod's tolerations.
The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator
. -
tolerations.key (string)
Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.
-
tolerations.operator (string)
Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.
Possible enum values:
"Equal"
"Exists"
-
tolerations.value (string)
Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.
-
tolerations.effect (string)
Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
Possible enum values:
"NoExecute"
Evict any already-running pods that do not tolerate the taint. Currently enforced by NodeController."NoSchedule"
Do not allow new pods to schedule onto the node unless they tolerate the taint, but allow all pods submitted to Kubelet without going through the scheduler to start, and allow all already-running pods to continue running. Enforced by the scheduler."PreferNoSchedule"
Like TaintEffectNoSchedule, but the scheduler tries not to schedule new pods onto the node, rather than prohibiting new pods from scheduling onto the node entirely. Enforced by the scheduler.
-
tolerations.tolerationSeconds (int64)
TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.
-
-
schedulerName (string)
If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler.
-
runtimeClassName (string)
RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info:
-
priorityClassName (string)
If specified, indicates the pod's priority. "system-node-critical" and "system-cluster-critical" are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.
-
priority (int32)
The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.
-
topologySpreadConstraints ([]TopologySpreadConstraint)
Patch strategy: merge on key
topologyKey
Map: unique values on keys
topologyKey, whenUnsatisfiable
will be kept during a mergeTopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed.
TopologySpreadConstraint specifies how to spread matching pods among the given topology.
-
topologySpreadConstraints.maxSkew (int32), required
MaxSkew describes the degree to which pods may be unevenly distributed. When
whenUnsatisfiable=DoNotSchedule
, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 1/1/0: | zone1 | zone2 | zone3 | | P | P | | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 1/1/1; scheduling it onto zone1(zone2) would make the ActualSkew(2-0) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. WhenwhenUnsatisfiable=ScheduleAnyway
, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. -
topologySpreadConstraints.topologyKey (string), required
TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. It's a required field.
-
topologySpreadConstraints.whenUnsatisfiable (string), required
WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field.
Possible enum values:
"DoNotSchedule"
instructs the scheduler not to schedule the pod when constraints are not satisfied."ScheduleAnyway"
instructs the scheduler to schedule the pod even if constraints are not satisfied.
-
topologySpreadConstraints.labelSelector (
LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.

-
terminationGracePeriodSeconds (int64)
Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. Defaults to 30 seconds.
-
activeDeadlineSeconds (int64)
Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer.
-

401: Unauthorized GET /api/v1/namespaces/{namespace}/pods/{name}/log name (in path): string, required name of the Pod namespace (in path): string, required container (in query): string The container for which to stream logs. Defaults to only container if there is one container in the pod. follow (in query): boolean Follow the log stream of the pod. Defaults to false. insecureSkipTLSVerifyBackend (in query): boolean insecureSkipTLSVerifyBackend indicates that the apiserver should not confirm the validity of the serving certificate of the backend it is connecting to. This will make the HTTPS connection between the apiserver and the backend insecure. This means the apiserver cannot verify the log data it is receiving came from the real kubelet. If the kubelet is configured to verify the apiserver's TLS credentials, it does not mean the connection to the real kubelet is vulnerable to a man in the middle attack (e.g. an attacker could not intercept the actual log data coming from the real kubelet). limitBytes (in query): integer If set, the number of bytes to read from the server before terminating the log output. This may not display a complete final line of logging, and may return slightly more or slightly less than the specified limit. pretty (in query): string previous (in query): boolean Return previous terminated container logs. Defaults to false. sinceSeconds (in query): integer A relative time in seconds before the current time from which to show logs. If this value precedes the time a pod was started, only logs since the pod start will be returned. If this value is in the future, no logs will be returned. Only one of sinceSeconds or sinceTime may be specified. tailLines (in query): integer If set, the number of lines from the end of the logs to show. If not specified, logs are shown from the creation of the container or sinceSeconds or sinceTime timestamps (in query): boolean If true, add an RFC3339 or RFC3339Nano timestamp at the beginning of every line of log output.
