validate third party resources
addresses validation portion of https://github.com/kubernetes/kubernetes/issues/22768
* ThirdPartyResource: validates name (3 segment DNS subdomain) and version names (single segment DNS label)
* ThirdPartyResourceData: validates objectmeta (name is validated as a DNS label)
* removes ability to use GenerateName with thirdpartyresources (kind and api group should not be randomized, in my opinion)
test improvements:
* updates resttest to clean up after create tests (so the same valid object can be used)
* updates resttest to take a name generator (in case "foo1" isn't a valid name for the object under test)
action required for alpha thirdpartyresource users:
* existing thirdpartyresource objects that do not match these validation rules will need to be removed/updated (after removing thirdpartyresourcedata objects stored under the disallowed versions, kind, or group names)
* existing thirdpartyresourcedata objects that do not match the name validation rule will not be able to be updated, but can be removed
In podSecurityPolicy:
1. Rename .seLinuxContext to .seLinux
2. Rename .seLinux.type to .seLinux.rule
3. Rename .runAsUser.type to .runAsUser.rule
4. Rename .seLinux.SELinuxOptions
1,2,3 as suggested by thockin in #22159.
I added 3 for consistency with 2.
Added selector generation to Job's
strategy.Validate, right before validation.
Can't do in defaulting since UID is not known.
Added a validation to Job to ensure that the generated
labels and selector are correct when generation was requested.
This happens right after generation, but validation is in a better
place to return an error.
Adds "manualSelector" field to batch/v1 Job to control selector generation.
Adds same field to extensions/__internal. Conversion between those two
is automatic.
Adds "autoSelector" field to extensions/v1beta1 Job. Used for storing batch/v1 Jobs
- Default for v1 is to do generation.
- Default for v1beta1 is to not do it.
- In both cases, unset == false == do the default thing.
Release notes:
Added batch/v1 group, which contains just Job, and which is the next
version of extensions/v1beta1 Job.
The changes from the previous version are:
- Users no longer need to ensure labels on their pod template are unique to the enclosing
job (but may add labels as needed for categorization).
- In v1beta1, job.spec.selector was defaulted from pod labels, with the user responsible for uniqueness.
In v1, a unique label is generated and added to the pod template, and used as the selector (other
labels added by user stay on pod template, but need not be used by selector).
- a new field called "manualSelector" field exists to control whether the new behavior is used,
versus a more error-prone but more flexible "manual" (not generated) seletor. Most users
will not need to use this field and should leave it unset.
Users who are creating extensions.Job go objects and then posting them using the go client
will see a change in the default behavior. They need to either stop providing a selector (relying on
selector generation) or else specify "spec.manualSelector" until they are ready to do the former.
This should allow users to update DaemonSet pods by manually deleting
the corresponding running pods. Users can use this mechanism for
DaemonSet updates until we implement Deployment style rolling update
for DaemonSet.
Leaving the type fields as comments for reference and reminder. But
deleting the conversion, defaulting and validation code. They can
always be brough back from the previous PR once the types are
introduced. Because builds break without them anyway that serves as a
reminder, so there is no need to leave them commented out.
