A Status returned by a schema or admission check often has a message and
no reason, and indexing the reason turned that into a KeyError traceback
instead of the message the user needs:
KeyError: 'reason'
Fall back to the message, then to the HTTP reason, and keep the reason in
the prefix only when the server sent one.

jmp admin create builds a Client or an Exporter from flags, which stops
where a resource has more shape than flags can carry: an ExporterSet's
selector, template and replica bounds have to be written as YAML. There
was no way to send that YAML to the cluster without kubectl.
Add jmp admin apply, the write half of jmp admin get:
jmp admin apply -f exporterset.yaml
jmp admin apply -f - --dry-run
Resources are sent as a server-side apply, so the same manifest creates a
resource and later updates it, and each one is reported the way kubectl
does, as created, configured or unchanged. The kind's plural name and
scope come from the cluster's discovery data rather than a table in this
client, so kinds added later - ExporterSet and VirtualTargetClass today -
apply without another release.
Only the jumpstarter.dev API groups are accepted. This is the Jumpstarter
admin CLI, not a general purpose kubectl apply, and a manifest naming any
other group is refused before anything reaches the cluster.

📝 WalkthroughWalkthroughThe change adds manifest validation and loading, Kubernetes server-side apply support, and the ChangesManifest Apply
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds a manifest-driven admin path that can create or update Jumpstarter resources. By default, it may overwrite fields owned by other controllers, and a multi-resource file can leave earlier changes applied when a later resource fails; malformed API error bodies and dry-run updates can also produce incorrect CLI behavior. These issues should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

"applyable" is not a word; the point was that a subresource is not a kind you can send a manifest for. Assisted-by: Claude Signed-off-by: Kirk Brauer <kirkebrauer@gmail.com>

In `@python/packages/jumpstarter-cli-admin/jumpstarter_cli_admin/k8s.py`:
- Line 18: Update the error-body handling around json.loads(e.body) so message
extraction only calls .get("message") for dictionary values; for null, lists,
strings, numbers, and other non-dictionaries, fall back to the existing reason
or "unknown error" and raise click.ClickException. Add a regression test
covering body="null".
In `@python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/apply.py`:
- Line 285: Update apply() and _action_taken() so dry-run results are evaluated
using the requested update rather than treating an unchanged
metadata.resourceVersion as unchanged; preserve normal server-backed comparison
behavior for non-dry-run operations. Add a server-backed test covering a changed
resource with dry_run=True and assert it is reported as configured.
- Line 222: Update ApplyV1Alpha1Api._server_side_apply so PATCH requests do not
include force=true by default; remove the unconditional force query parameter
and add an explicit opt-in mechanism for callers that need conflict forcing,
while preserving the existing fieldManager parameter.

Server-side apply sent force=true on every request, so `jmp admin apply` silently took ownership of any field another manager held. Make it opt-in behind --force-conflicts, as kubectl does, and point at the flag when a conflict is what stopped the apply. A dry run is never persisted, so its resource version does not move either and every dry run reported "unchanged". Compare what the server says the object would become instead, ignoring the fields the server owns. Also stop reading a non-Status JSON error body as a Status: a proxy in front of the API server can answer with null, a list, or a bare string, which raised AttributeError instead of the server's error.

jmp admin apply -f <file|->. Resources are sent as a server-side apply, so the same manifest creates a resource and later updates it, and each is reported the way kubectl does — created, configured or unchanged. Kind plurals and scope come from the cluster's discovery data rather than a table in this client, so kinds added later apply without another release. Only the jumpstarter.dev API groups are accepted; a manifest naming any other group is refused before anything reaches the cluster.Conflicts are reported rather than won. An apply that would take a field another manager owns fails and names the field;
--force-conflictstakes it deliberately, as in kubectl.Also fixes
handle_k8s_api_exception, which raisedKeyError: 'reason'on any Status without one — which is what a schema or admission failure returns, so those surfaced as tracebacks instead of the server's message.
