bootstrap:
description: |-
Bootstrap defines the Envoy Bootstrap as a YAML string.
Visit https://www.envoyproxy.io/docs/envoy/latest/api-v3/config/bootstrap/v3/bootstrap.proto#envoy-v3-api-msg-config-bootstrap-v3-bootstrap
to learn more about the syntax.
If set, this is the Bootstrap configuration used for the managed Envoy Proxy fleet instead of the default Bootstrap configuration
set by Envoy Gateway.
Some fields within the Bootstrap that are required to communicate with the xDS Server (Envoy Gateway) and receive xDS resources
from it are not configurable and will result in the `EnvoyProxy` resource being rejected.
Backward compatibility across minor versions is not guaranteed.
We strongly recommend using `egctl x translate` to generate a `EnvoyProxy` resource with the `Bootstrap` field set to the default
Bootstrap configuration used. You can edit this configuration, and rerun `egctl x translate` to ensure there are no validation errors.

seLinuxChangePolicy defines how the container's SELinux label is applied to all volumes used by the Pod.
It has no effect on nodes that do not support SELinux or to volumes does not support SELinux.
Valid values are "MountOption" and "Recursive".
"Recursive" means relabeling of all files on all Pod volumes by the container runtime.
This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node.
"MountOption" mounts all eligible Pod volumes with `-o context` mount option.
This requires all Pods that share the same volume to use the same SELinux label.
It is not possible to share the same volume among privileged and unprivileged Pods.
Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes
whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their
CSIDriver instance. Other volumes are always re-labelled recursively.
"MountOption" value is allowed only when SELinuxMount feature gate is enabled.
If not specified and SELinuxMount feature gate is enabled, "MountOption" is used.
If not specified and SELinuxMount feature gate is disabled, "MountOption" is used for ReadWriteOncePod volumes
and "Recursive" for all other volumes.
This field affects only Pods that have SELinux label set, either in PodSecurityContext or in SecurityContext of all containers.

maxSkew:
description: |-
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.
The global minimum is the minimum number of matching pods in an eligible domain
or zero if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 2/2/1:
In this case, the global minimum is 1.
| zone1 | zone2 | zone3 |
| P P | P P | P |
- if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2;
scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2)
violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto any zone.
When `whenUnsatisfiable=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.
format: int32
type: integer
minDomains:
description: |-
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed.
And when the number of eligible domains with matching topology keys equals or greater than minDomains,
this value has no effect on scheduling.
As a result, when the number of eligible domains is less than minDomains,
scheduler won't schedule more than maxSkew Pods to those domains.
If value is nil, the constraint behaves as if MinDomains is equal to 1.
Valid values are integers greater than 0.
When value is not nil, WhenUnsatisfiable must be DoNotSchedule.
For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same
labelSelector spread as 2/2/2:
| zone1 | zone2 | zone3 |
| P P | P P | P P |
The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0.
In this situation, new pod with the same labelSelector cannot be scheduled,
because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew.

whenUnsatisfiable:
description: |-
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.

ephemeral:
description: |-
ephemeral represents a volume that is handled by a cluster storage driver.
The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts,
and deleted when the pod is removed.
Use this if:
a) the volume is only needed while the pod runs,
b) features of normal volumes like restoring from snapshot or capacity
tracking are needed,
c) the storage driver is specified through a storage class, and
d) the storage driver supports dynamic volume provisioning through
a PersistentVolumeClaim (see EphemeralVolumeSource for more
information on the connection between this volume type
and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific
APIs for volumes that persist for longer than the lifecycle
of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to
be used that way - see the documentation of the driver for
more information.
A pod can use both types of ephemeral volumes and
persistent volumes at the same time.
properties:
volumeClaimTemplate:
description: |-
Will be used to create a stand-alone PVC to provision the volume.
The pod in which this EphemeralVolumeSource is embedded will be the
owner of the PVC, i.e. the PVC will be deleted together with the
pod. The name of the PVC will be `<pod name>-<volume name>` where
`<volume name>` is the name from the `PodSpec.Volumes` array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod
will *not* be used for the pod to avoid using an unrelated
volume by mistake. Starting the pod is then blocked until
the unrelated PVC is removed. If such a pre-created PVC is
meant to be used by the pod, the PVC has to updated with an
owner reference to the pod once the pod exists. Normally
this should not be necessary, but it may be useful when
manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes
to the PVC after it has been created.

When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.

image:
description: |-
image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet's host machine.
The volume is resolved at pod startup depending on which PullPolicy value is provided:
- Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
- Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present.
- IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation.
A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message.
The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field.
The OCI object gets mounted in a single directory (spec.containers[*].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images.
The volume will be mounted read-only (ro) and non-executable files (noexec).
Sub path mounts for containers are not supported (spec.containers[*].volumeMounts.subpath) before 1.33.
The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.
properties:

IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
Defaults to Always if :latest tag is specified, or IfNotPresent otherwise.
type: string

podCertificate:
description: |-
Projects an auto-rotating credential bundle (private key and certificate
chain) that the pod can use either as a TLS client or server.
Kubelet generates a private key and uses it to send a
PodCertificateRequest to the named signer. Once the signer approves the
request and issues a certificate chain, Kubelet writes the key and
certificate chain to the pod filesystem. The pod does not start until
certificates have been issued for each podCertificate projected volume
source in its spec.
Kubelet will begin trying to rotate the certificate at the time indicated
by the signer using the PodCertificateRequest.Status.BeginRefreshAt
timestamp.
Kubelet can write a single file, indicated by the credentialBundlePath
field, or separate files, indicated by the keyPath and
certificateChainPath fields.
The credential bundle is a single file in PEM format. The first PEM
entry is the private key (in PKCS#8 format), and the remaining PEM
entries are the certificate chain issued by the signer (typically,
signers will return their certificate chain in leaf-to-root order).
Prefer using the credential bundle format, since your application code
can read it atomically. If you use keyPath and certificateChainPath,
your application must make two separate file reads. If these coincide
with a certificate rotation, it is possible that the private key and leaf
certificate you read may not correspond to each other. Your application
will need to check for this condition, and re-read until they are
consistent.
The named signer controls chooses the format of the certificate it
issues; consult the signer implementation's documentation to learn how to
use the certificates it issues.
properties:
certificateChainPath:
description: |-
Write the certificate chain at this path in the projected volume.
Most applications should use credentialBundlePath. When using keyPath
and certificateChainPath, your application needs to check that the key
and leaf certificate are consistent, because it is possible to read the
files mid-rotation.
type: string
credentialBundlePath:
description: |-
Write the credential bundle at this path in the projected volume.
The credential bundle is a single file that contains multiple PEM blocks.
The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
key.
The remaining blocks are CERTIFICATE blocks, containing the issued
certificate chain from the signer (leaf and any intermediates).
Using credentialBundlePath lets your Pod's application code make a single
atomic read that retrieves a consistent key and certificate chain. If you
project them to separate files, your application code will need to
additionally check that the leaf certificate was issued to the key.
type: string
keyPath:

will reject values shorter than 3600 (1 hour). The maximum allowable
value is 7862400 (91 days).
The signer implementation is then free to issue a certificate with any
lifetime *shorter* than MaxExpirationSeconds, but no shorter than 3600
seconds (1 hour). This constraint is enforced by kube-apiserver.
`kubernetes.io` signers will never issue certificates with a lifetime

The maximum number of nodes with an existing available DaemonSet pod that

Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%).
This can not be 0 if MaxUnavailable is 0.
Absolute number is calculated from percentage by rounding up to a minimum of 1.

Example: when this is set to 30%, at most 30% of the total number of nodes
that should be running the daemon pod (i.e. status.desiredNumberScheduled)
can have their a new pod created before the old pod is marked as deleted.
The update starts by launching new pods on 30% of nodes. Once an updated
pod is available (Ready for at least minReadySeconds) the old DaemonSet pod
on that node is marked deleted. If the old pod becomes unavailable for any
reason (Ready transitions to false, is evicted, or is drained) an updated
pod is immediately created on that node without considering surge limits.
Allowing surge implies the possibility that the resources consumed by the
daemonset on any given node can double if the readiness check fails, and
so resource intensive daemonsets should take into account that they may
cause evictions during disruption.

If ReadOnly is false, this field has no meaning and must be unspecified.
If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).

RestartPolicy defines the restart behavior of individual containers in a pod.
This overrides the pod-level restart policy. When this field is not specified,
the restart behavior is defined by the Pod's restart policy and the container type.
Additionally, setting the RestartPolicy as "Always" for the init container will
have the following effect:
this init container will be continually restarted on
exit until all regular containers have terminated. Once all regular
containers have completed, all init containers with restartPolicy "Always"
will be shut down. This lifecycle differs from normal init containers and
is often referred to as a "sidecar" container. Although this init
container still starts in the init container sequence, it does not wait
for the container to complete before proceeding to the next init
container. Instead, the next init container starts immediately after this
init container is started, or after any startupProbe has successfully
completed.

is restarted or not. Constraints on the rules:

seLinuxChangePolicy:
description: |-
seLinuxChangePolicy defines how the container's SELinux label is applied to all volumes used by the Pod.
It has no effect on nodes that do not support SELinux or to volumes does not support SELinux.
Valid values are "MountOption" and "Recursive".
"Recursive" means relabeling of all files on all Pod volumes by the container runtime.
This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node.
"MountOption" mounts all eligible Pod volumes with `-o context` mount option.
This requires all Pods that share the same volume to use the same SELinux label.
It is not possible to share the same volume among privileged and unprivileged Pods.
Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes
whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their
CSIDriver instance. Other volumes are always re-labelled recursively.
"MountOption" value is allowed only when SELinuxMount feature gate is enabled.
If not specified and SELinuxMount feature gate is enabled, "MountOption" is used.
If not specified and SELinuxMount feature gate is disabled, "MountOption" is used for ReadWriteOncePod volumes
and "Recursive" for all other volumes.
This field affects only Pods that have SELinux label set, either in PodSecurityContext or in SecurityContext of all containers.
All Pods that use the same volume should use the same seLinuxChangePolicy, otherwise some pods can get stuck in ContainerCreating state.
Note that this field cannot be set when spec.os.name is windows.

maxSkew:
description: |-
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.
The global minimum is the minimum number of matching pods in an eligible domain
or zero if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 2/2/1:
In this case, the global minimum is 1.
| zone1 | zone2 | zone3 |
| P P | P P | P |
- if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2;
scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2)
violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto any zone.
When `whenUnsatisfiable=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.
format: int32
type: integer
minDomains:
description: |-
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed.
And when the number of eligible domains with matching topology keys equals or greater than minDomains,
this value has no effect on scheduling.
As a result, when the number of eligible domains is less than minDomains,
scheduler won't schedule more than maxSkew Pods to those domains.
If value is nil, the constraint behaves as if MinDomains is equal to 1.
Valid values are integers greater than 0.
When value is not nil, WhenUnsatisfiable must be DoNotSchedule.
For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same
labelSelector spread as 2/2/2:
| zone1 | zone2 | zone3 |
| P P | P P | P P |
The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0.
In this situation, new pod with the same labelSelector cannot be scheduled,
because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew.
format: int32
type: integer
nodeAffinityPolicy:
description: |-
NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector
when calculating pod topology spread skew. Options are:
- Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations.
- Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations.
If this value is nil, the behavior is equivalent to the Honor policy.
type: string
nodeTaintsPolicy:
description: |-
NodeTaintsPolicy indicates how we will treat node taints when calculating
pod topology spread skew. Options are:
- Honor: nodes without taints, along with tainted nodes for which the incoming pod
has a toleration, are included.
- Ignore: node taints are ignored. All nodes are included.
If this value is nil, the behavior is equivalent to the Ignore policy.
type: string
topologyKey:
description: |-
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.
We define a domain as a particular instance of a topology.
Also, we define an eligible domain as a domain whose nodes meet the requirements of
nodeAffinityPolicy and nodeTaintsPolicy.
e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology.
And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology.
It's a required field.
type: string
whenUnsatisfiable:
description: |-
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.

ephemeral:
description: |-
ephemeral represents a volume that is handled by a cluster storage driver.
The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts,
and deleted when the pod is removed.
Use this if:
a) the volume is only needed while the pod runs,
b) features of normal volumes like restoring from snapshot or capacity
tracking are needed,
c) the storage driver is specified through a storage class, and
d) the storage driver supports dynamic volume provisioning through
a PersistentVolumeClaim (see EphemeralVolumeSource for more
information on the connection between this volume type
and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific
APIs for volumes that persist for longer than the lifecycle
of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to
be used that way - see the documentation of the driver for
more information.
A pod can use both types of ephemeral volumes and
persistent volumes at the same time.
properties:
volumeClaimTemplate:
description: |-
Will be used to create a stand-alone PVC to provision the volume.
The pod in which this EphemeralVolumeSource is embedded will be the
owner of the PVC, i.e. the PVC will be deleted together with the
pod. The name of the PVC will be `<pod name>-<volume name>` where
`<volume name>` is the name from the `PodSpec.Volumes` array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod
will *not* be used for the pod to avoid using an unrelated
volume by mistake. Starting the pod is then blocked until
the unrelated PVC is removed. If such a pre-created PVC is
meant to be used by the pod, the PVC has to updated with an
owner reference to the pod once the pod exists. Normally
this should not be necessary, but it may be useful when
manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes
to the PVC after it has been created.

it will create a new volume based on the contents of the specified data source.

dataSourceRef specifies the object from which to populate the volume with data, if a non-empty

core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.

image:

image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet's host machine.
The volume is resolved at pod startup depending on which PullPolicy value is provided:
- Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
- Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present.
- IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation.
A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message.
The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field.
The OCI object gets mounted in a single directory (spec.containers[*].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images.
The volume will be mounted read-only (ro) and non-executable files (noexec).
Sub path mounts for containers are not supported (spec.containers[*].volumeMounts.subpath) before 1.33.

of ClusterTrustBundle objects in an auto-updating file.
Alpha, gated by the ClusterTrustBundleProjection feature gate.
ClusterTrustBundle objects can either be selected by name, or by the
combination of signer name and a label selector.
Kubelet performs aggressive normalization of the PEM contents written
into the pod filesystem. Esoteric PEM features such as inter-block
comments and block headers are stripped. Certificates are deduplicated.
The ordering of certificates within the file is arbitrary, and Kubelet
may change the order over time.

podCertificate:
description: |-
Projects an auto-rotating credential bundle (private key and certificate
chain) that the pod can use either as a TLS client or server.
Kubelet generates a private key and uses it to send a
PodCertificateRequest to the named signer. Once the signer approves the
request and issues a certificate chain, Kubelet writes the key and
certificate chain to the pod filesystem. The pod does not start until
certificates have been issued for each podCertificate projected volume
source in its spec.
Kubelet will begin trying to rotate the certificate at the time indicated
by the signer using the PodCertificateRequest.Status.BeginRefreshAt
timestamp.
Kubelet can write a single file, indicated by the credentialBundlePath
field, or separate files, indicated by the keyPath and
certificateChainPath fields.
The credential bundle is a single file in PEM format. The first PEM
entry is the private key (in PKCS#8 format), and the remaining PEM
entries are the certificate chain issued by the signer (typically,
signers will return their certificate chain in leaf-to-root order).
Prefer using the credential bundle format, since your application code
can read it atomically. If you use keyPath and certificateChainPath,
your application must make two separate file reads. If these coincide
with a certificate rotation, it is possible that the private key and leaf
certificate you read may not correspond to each other. Your application
will need to check for this condition, and re-read until they are
consistent.
The named signer controls chooses the format of the certificate it
issues; consult the signer implementation's documentation to learn how to
use the certificates it issues.
properties:
certificateChainPath:
description: |-
Write the certificate chain at this path in the projected volume.
Most applications should use credentialBundlePath. When using keyPath
and certificateChainPath, your application needs to check that the key
and leaf certificate are consistent, because it is possible to read the
files mid-rotation.
type: string
credentialBundlePath:
description: |-
Write the credential bundle at this path in the projected volume.
The credential bundle is a single file that contains multiple PEM blocks.
The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
key.
The remaining blocks are CERTIFICATE blocks, containing the issued
certificate chain from the signer (leaf and any intermediates).
Using credentialBundlePath lets your Pod's application code make a single
atomic read that retrieves a consistent key and certificate chain. If you
project them to separate files, your application code will need to
additionally check that the leaf certificate was issued to the key.
type: string
keyPath:

will reject values shorter than 3600 (1 hour). The maximum allowable
value is 7862400 (91 days).
The signer implementation is then free to issue a certificate with any
lifetime *shorter* than MaxExpirationSeconds, but no shorter than 3600
seconds (1 hour). This constraint is enforced by kube-apiserver.
`kubernetes.io` signers will never issue certificates with a lifetime
longer than 24 hours.
