Currently we only care about the sum of sandbox resources, which
includes a pod overhead if defined. We have a need for also calculating
*just* the sum of container requests/limits for CPU / Memory, so let's
do a refactor and expose this new helper function.

This fixes a bug where the test was dependent on the current set of
feature gates. Since AllFeatureEnabledContainers() depends on the
feature gates it must be evaluated after the test case is initialized.
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.
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.".
Headless+selectorless -> RequireDualStack
Headless+selector -> SingleStack
Add test cases to cover this and ExternalName and dual-stack init (which
I think can never trigger, but best to be safe).
This scaffolding allows us to assert more on each test case, and more
consistently.
Set input fields from output fields IFF they are expected AND not set on
input. This allows us to verify the "after" state (expected) whether
the test case specified the value or not, and still pass the generic
cmp.Equal.
Use this in a few tests to prove its worth, more to do.
Some of the existing tests that are focused on create and delete can
probably be replaced by these.
This could be used in other test cases that are open-coding a lot of the
same stuff. Later commits.
This includes a few cases.
1) TestCreateIgnoresIPFamilyForExternalName: Prove that ExternalName is
ignored for dual-stack. A small set of test cases were chosen to
demonstrate.
2) TestCreateIgnoresIPFamilyWithoutDualStack: Prove that when the
dual-stack gate is off, all services are ignored for dual-stack. A
small set of test cases were chosen to demonstrate
3) TestCreateInitIPFields: Run over a huge array of test cases for
dual-stack. This was generated by this program:
https://gist.github.com/thockin/cccc9c9a580b4830ee0946ddd43eeafe and
then updated by hand.
Prior to 1.22 a user could change NodePort values within a service
during an update, and the apiserver would allocate values for any that
were not specified.
Consider a YAML like:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
type: NodePort
ports:
- name: p
port: 80
- name: q
port: 81
selector:
app: foo
```
When this is created, nodeport values will be allocated for each port.
Something like:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
clusterIP: 10.0.149.11
type: NodePort
ports:
- name: p
nodePort: 30872
port: 80
protocol: TCP
targetPort: 9376
- name: q
nodePort: 31310
port: 81
protocol: TCP
targetPort: 81
selector:
app: foo
```
If the user PUTs (kubectl replace) the original YAML, we would see that
`.nodePort = 0`, and allocate new ports. This was ugly at best.
In 1.22 we fixed this to not allocate new values if we still had the old
values, but instead re-assign them. Net new ports would still be seen
as `.nodePort = 0` and so new allocations would be made.
This broke a corner case as follows:
Prior to 1.22, the user could PUT this YAML:
```
apiVersion: v1
kind: Service
metadata:
name: foo
spec:
type: NodePort
ports:
- name: p
nodePort: 31310 # note this is the `q` value
port: 80
- name: q
# note this nodePort is not specified
port: 81
selector:
app: foo
```
The `p` port would take the `q` port's value. The `q` port would be
seen as `.nodePort = 0` and a new value allocated. In 1.22 this results
in an error (duplicate value in `p` and `q`).
This is VERY minor but it is an API regression, which we try to avoid,
and the fix is not too horrible.
This commit adds more robust testing of this logic.
This patch adds removal warnings for the deprecated seccomp annotation,
which is targeting removal in v1.25.
