A Client or Exporter exists the moment it is created, but its credentials and endpoint arrive later — or never, in a namespace nothing is watching. Reading one in that state failed with a traceback rather than an explanation:

jmp admin import client fresh   -> AttributeError: 'NoneType' object has no attribute 'credential'
jmp admin get exporter          -> KeyError: 'status'

Makes the exporter's status optional the way the client's already is, so a status-less exporter lists and renders, and raises CredentialNotReadyError from get_client_config / get_exporter_config, which jmp admin import reports as a message naming the likely cause.

📝 Walkthrough

Walkthrough

Kubernetes client and exporter configuration paths now detect missing credentials before secret access. Exporter parsing and rendering support absent status. Administrative imports convert Kubernetes errors into Click exceptions. Tests cover readiness errors, status-less exporters, and default rendering.

Changes

Credential readiness handling

Layer / File(s) Summary
Client credential readiness
python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/exceptions.py, python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/clients.py, python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/clients_test.py
CredentialNotReadyError reports resources without credentials. get_client_config raises it before reading the secret. Tests verify the error and skipped secret access.
Exporter status and credentials
python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/exporters.py, python/packages/jumpstarter-kubernetes/jumpstarter_kubernetes/exporters_test.py
Exporter status fields and parsing now support missing controller status. Rendering uses default values. Configuration raises CredentialNotReadyError when credentials are unavailable.
Click error conversion
python/packages/jumpstarter-cli-admin/jumpstarter_cli_admin/import_res.py
Client and exporter imports convert JumpstarterKubernetesError into chained click.ClickException instances.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to cfa4b

Status-less exporters can still disappear from device listings when the devices view is enabled, preventing users from seeing resources that exist but are not yet reconciled. The change is otherwise mergeable with explicit owner follow-up to render these exporters as Unknown.

Poem

A rabbit checks the client’s new state

No secret yet? It will wait.
Exporters show blanks in their row,
While clear Click errors now flow.
Tests guard each hop at the gate.

A Client or Exporter exists the moment it is created, but its credentials
and endpoint arrive later, when the controller reconciles it - or never,
if nothing is watching that namespace. Reading one in that state failed
with a traceback rather than an explanation:

    jmp admin import client fresh
    AttributeError: 'NoneType' object has no attribute 'credential'

    jmp admin get exporter
    KeyError: 'status'

Make the exporter's status optional the way the client's already is, so a
status-less exporter lists and renders (as Unknown, with no endpoint and
no devices), and raise CredentialNotReadyError from get_client_config and
get_exporter_config, which jmp admin import reports as:

    Error: The client 'fresh' has no credentials yet. The Jumpstarter
    controller issues them shortly after the resource is created; check
    that it is running and watching this namespace, then try again.

`jmp admin get exporter -d` enumerates one row per device, so an exporter
with none to enumerate produced no rows and vanished from the listing —
"No resources found" for a resource that plainly exists. That covers an
exporter the controller has not reconciled yet, and also one that has simply
never run, which has a status but an empty device list.

Emit a single row with empty label and UUID columns in that case.

@bennyz I added a few new tweaks if you could review :)

mangelajo pushed a commit to mangelajo/jumpstarter that referenced this pull request Sep 1, 2026
…ev#1044)

`jmp admin get client|exporter -o json|yaml` rebuilt each object's
metadata without its labels, so the field an exporter is selected by was
missing from output the command had already fetched it in. Anything
grouping or filtering exporters had to fall back to kubectl.

Touches the same four files as jumpstarter-dev#1045, so whichever merges second needs a
trivial rebase.
