* De-share the Handler struct in core API
An upcoming PR adds a handler that only applies on one of these paths.
Having fields that don't work seems bad.
This never should have been shared. Lifecycle hooks are like a "write"
while probes are more like a "read". HTTPGet and TCPSocket don't really
make sense as lifecycle hooks (but I can't take that back). When we add
gRPC, it is EXPLICITLY a health check (defined by gRPC) not an arbitrary
RPC - so a probe makes sense but a hook does not.
In the future I can also see adding lifecycle hooks that don't make
sense as probes. E.g. 'sleep' is a common lifecycle request. The only
option is `exec`, which requires having a sleep binary in your image.
* Run update scripts
Listing these explicitly makes it easier to determine whether a new
Container field has been evaluated for use with ephemeral containers.
This does not change the behavior of ephemeral containers.
The feature gate gets locked to "true", with the goal to remove it in two
releases.
All code now can assume that the feature is enabled. Tests for "feature
disabled" are no longer needed and get removed.
Some code wasn't using the new helper functions yet. That gets changed while
touching those lines.
This adds a test case to cover the scenario where the fields of an
ephemeral container conflict with other fields in the pod and must be
detected by full PodSpec validation.
Previously this only validated the ephemeral containers, but it's safer
to validate the entire PodSpec in case other parts of validation add
logic that checks ephemeral containers.
Remove the VolumeSubpath feature gate.
Feature gate convention has been updated since this was introduced to
indicate that they "are intended to be deprecated and removed after a
feature becomes GA or is dropped.".
This commit started as removing FIXME comments, but in doing so I
realized that the IP allocation process was using unvalidated user
input. Before de-layering, validation was called twice - once before
init and once after, which the init code depended on.
Fortunately (or not?) we had duplicative checks that caught errors but
with less friendly messages.
This commit calls validation before initializing the rest of the
IP-related fields.
This also re-organizes that code a bit, cleans up error messages and
comments, and adds a test SPECIFICALLY for the errors in those cases.
This was causing tests to pass which ought not be passing. This is not
an API change because we default the value of it when needed. So we
would never see this in the wild, but it makes the tests sloppy.
This is the last layered method. All allocator logic is moved to the
beginUpdate() path. Removing the now-useless layer will happen in a
subsequent commit.
Modify the behavior of the AnyVolumeDataSource alpha feature gate to enable
a new field, DataSourceRef, rather than modifying the behavior of the
existing DataSource field. This allows addition Volume Populators in a way
that doesn't risk breaking backwards compatibility, although it will
result in eventually deprecating the DataSource field.

This will only work if the "ReadWriteOncePod" feature gate is enabled.
Additionally, this access mode will only work when used by itself. This
is because when ReadWriteOncePod is used on a PV or PVC, it renders all
other access modes useless since it is most restrictive.
kubelet is the only writer of v1.Node .status.images[].names. When an
image has neither RepoDigests nor RepoTags, the value gets stored in
etcd as null. Marking the field as optional can help JSON API clients
to avoid hitting serialization error when the returned status contains
null .status.images[].names.
This changes the `/ephemeralcontainers` subresource of `/pods` to use
the `Pod` kind rather than `EphemeralContainers`.
When designing this API initially it seemed preferable to create a new
kind containing only the pod's ephemeral containers, similar to how
binding and scaling work.
It later became clear that this made admission control more difficult
because the controller wouldn't be presented with the entire Pod, so we
updated this to operate on the entire Pod, similar to how `/status`
works.
Now that the EndpointSlice API and controllers are GA, the Endpoints
controller will use this annotation to warn when Endpoints are over
capacity. In a future release, this warning will be replaced with
truncation.
As discussed during the alpha review, the ReadOnly field is not really
needed because volume mounts can also be read-only. It's a historical
oddity that can be avoided for generic ephemeral volumes as part
of the promotion to beta.

This is part of the goal for scheduling to remove dependencies on internal
packages for the scheduling framework. It also provides these functions in an
external location for other components and projects to import.
The goal of this move is related to issue 89930, to break the dependence
of scheduling plugins on internal helpers. This function can easily move to
component-helpers where it will be used by other components as well.
