feat(resource)!: require a DynamicClient as a keyword-only client - #2798
Make the dynamic client mandatory across the wrapper API, make the breaking contract explicit at the call site, and bring the documentation and the docs snippets in line with it.
client: DynamicClient is a required keyword-only argument on Resource / NamespacedResource. name (and namespace) are the leading positional parameters again, so Foo("name", client=c) binds correctly instead of raising got multiple values for argument 'client'.
New MissingClientError (subclass of TypeError, so existing except TypeError handlers keep working) carries a migration hint and is raised when client is None.
dyn_client, config_file, config_dict and context are removed from the resource APIs and rejected with Unsupported argument(s): ... Pass a DynamicClient via client= from get_client() instead. The same rejection now reaches constructors, and unknown kwargs name the instantiated class (Pod() got unexpected keyword argument(s): ...).
Client validation is eager: Resource.get_all_cluster_resources and Event.get used to be generator functions whose client is None guard only fired on first next(); both now validate at call time and return an inner generator. The dead *args escape hatch on get_all_cluster_resources is gone, so extra positionals fail immediately.
42 hand-written __init__s (37 files) no longer declare client=None; the client flows through **kwargs, which removes the false "optional" signal that let a missing-client call slip into NodeNetworkConfigurationPolicy._get_port_from_nns.
Raises: sections added to the six client-facing APIs; AGENTS.md documents both the required client and the removed kwargs; both runnable examples that the change would have broken (examples/role.py, examples/node_network_configuration_policy.py) now create a client.
BREAKING CHANGE — every call site must pass an explicit client from get_client() (or get_client(fake=True)). Version bump to the next major is done manually at release.
still valid; client is keyword-only on the constructor
client=None raises ocp_resources.exceptions.MissingClientError; omitting client entirely raises TypeError from Python's own argument binding.
Watch out: where client sat in the middle of a legacy subclass signature, old positional calls no longer fail loudly — the argument silently binds to the next parameter (Secret("n", "ns", client) now sets accesskeyid; BridgeNetworkAttachmentDefinition(...) takes mtu where it used to take client). Construct these with keywords. This is called out in the new migration section of the docs.
Docs
docs/*.md is the source for the docs site (the HTML is built in Actions), so the breaking change is documented here rather than deferred:
docs/resource-api.md — client is required/keyword-only, the removed kwargs are rejected, the get() / get_all_cluster_resources() signatures and parameter tables match the code, and a new Migrating to the Mandatory client section carries the before/after table plus the positional-misbinding warning above.
docs/error-handling.md — new MissingClientError section (import list, __str__ output, which entry points raise it) and the hierarchy table now records that it derives from TypeError.
docs/connecting-to-clusters.md — "the library creates a client automatically, but this triggers a FutureWarning" replaced by the real contract, and the FutureWarning troubleshooting entry became the TypeError: Unsupported argument(s) one.
docs/creating-and-managing-resources.md, docs/querying-resources.md, docs/working-with-events.md — stale client/dyn_client claims and signatures replaced.
30 snippets across 6 pages (working-with-virtual-machines.md, editing-resources-temporarily.md, validating-resources.md, quickstart.md, generating-resource-classes.md, connecting-to-clusters.md) now pass client=client, matching the convention already used by common-patterns.md. They were broken by the mandatory-client change and nothing executed them.
Guarding against the same drift
tests/test_examples_client.py statically checks every construction of a Resource/NamespacedResource subclass — plus get/list/get_all_cluster_resources/delete_events and the Event APIs — for an explicit client, covering aliased imports, module-qualified calls and positional classmethod clients. It now also scans the fenced Python blocks in docs/*.md through the same AST detector (absolute line numbers, dedented list-nested fences, signature fragments skipped with a parsed-block floor so the skip cannot silently swallow the real snippets). That guard is what turned the 30 stale docs snippets up.
prek run — ruff, ruff-format, flake8, mypy, secret scanners all green
New coverage: eager MissingClientError without list(), constructor rejecting a removed kwarg with the migration hint, unknown kwargs naming the class, issubclass(MissingClientError, TypeError), the docs-snippet guard, and the Markdown extractor (absolute line numbers, non-python fences, list-nested fences)
Confirm CI green
Follow-ups (not in this PR)
Omitting client entirely raises Python's own TypeError: NamespacedResource.__init__() missing 1 required keyword-only argument: 'client', which names the base class and drops the get_client() hint; only client=None reaches MissingClientError. Fixing that needs a sentinel default and was deliberately left out of this PR.
tests/test_examples_client.py guards examples/ and docs/*.md only — tests/ and mcp_server/ rely on their own suites.
Review
Qodo, CodeRabbit and a 7-stream review loop (quality, guidelines, security, docs, spec, plus two independent cross-model peers) ran on the implementation. A follow-up review of the branch flagged the documentation drift (now fixed here) and the misnamed migration test (renamed here).
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
No actionable comments were generated in the recent review.
Walkthrough
Resource construction, lookup, and event APIs now require explicit clients. They reject missing clients and no longer create clients from configuration. Examples, tests, and review guidance now show or check explicit client propagation.
Resource construction and lookup APIs require explicit clients. They reject removed configuration arguments and no longer create clients implicitly. Tests cover missing clients and rejected arguments.
The explicit-client migration is mergeable on the available evidence. Event options remain positional for compatibility.

Require explicit DynamicClient across Resource and Event APIs
✨ Enhancement🧪 Tests📝 Documentation🕐 40+ Minutes
AI Description
• Require an explicit DynamicClient for resource construction, retrieval, cluster listing, and Event
operations.
• Remove implicit client creation and deprecated arguments; reject unsupported calls with
TypeErrors.
• Update examples, contributor guidance, and tests for the breaking API change.
Requiring the client at API boundaries and retaining configuration options only in get_client() directly supports the intended explicit-client contract. Keeping implicit client creation for compatibility would undermine that contract.

1. Recorded resources cannot be cleaned up✗ Dismissed
Description
Resource.__init__ now requires client, but mtv-api-tests reconstructs resources in
tools/clean_cluster.py with only their recorded name and namespace. When users run the documented
cleanup command against resources.json, construction raises TypeError before clean_up() runs.
2. Node network policy port backup now crashes✓ Resolved
NodeNetworkConfigurationPolicy._get_port_from_nns() still builds
NodeNetworkState(name=self.nodes[0].name) without a client. NodeNetworkState.__init__ defaults
client=None and hands it to Resource.__init__, which now raises `TypeError("client is
required"), so any NNCP flow that backs up ports through _ports_backup()` fails before it reads
the node interfaces.
3. Copied Resource constructor example is a SyntaxError✓ Resolved
The invalid Resource(name=..., *, client=...) snippet was replaced with a valid
Resource(name="my-resource", client=client) call, and the keyword-only contract is now explained
in prose as a signature rather than a call example, so copying the snippet no longer yields a
SyntaxError.
Description
The Resource(...) call example in resource-api.md places a bare *, marker inside a call's
argument list, which Python rejects at parse time. Readers who copy the snippet as written get a
SyntaxError before any client is created, and the snippet is an unchecked signature fragment, so the
docs guard does not catch it.
4. Client guard misses resources imported as module names✓ Resolved
_import_aliases only records module_names from import ocp_resources... statements, never from
from ocp_resources import role or from ocp_resources import pod as p, so role.Role(name=...)
or p.Pod(...) is treated as an unrelated attribute call and never flagged. A future example
written in this idiomatic form that builds a resource without a client passes the guard silently,
which defeats the purpose of the test.
5. Client guard misses resource aliases of Event✓ Resolved
_import_aliases maps an alias to a class only when the class is in resource_names, and Event
is deliberately excluded from that set, so from ocp_resources.event import Event as E leaves E
unmapped. E.get() and E.delete_events() then go unchecked even though Event APIs require a
client.
View medium (8) 6. Many resource classes still say client is optional✓ Resolved
The commit removes the optional client=None parameter from the subclass __init__ signatures across
all the flagged resource classes (node_network_state.py, secret.py, virtual_machine.py, job.py,
persistent_volume_claim.py, role.py, and many others), so client is no longer advertised as
optional. It also makes the base Resource/NamespacedResource take client as a required keyword-only
argument (*, client: DynamicClient) and raises MissingClientError eagerly when it is None. Callers
must now pass client explicitly, and the NodeNetworkPolicy call site is fixed to pass
client=self.client.
Description
Many hand-written subclasses still declare client=None as an optional, often non-first parameter.
Examples are NodeNetworkState, Secret, VirtualMachine, Job, PersistentVolumeClaim and
Role, and they pass that value on to the now-mandatory Resource.__init__. Their signatures and
IDE hints still tell callers the client can be left out, but leaving it out now fails only at
runtime with TypeError. That is exactly how the missed NodeNetworkState(name=...) call above got
through.
7. test_removed_client_kwargs_rejected is untyped✓ Resolved
Description
The new test method has no -> None annotation, and its fake_client parameter is unannotated. New
test methods are functions covered by the type-hint requirement.
8. test_client_is_required is untyped✓ Resolved
Description
The new test method has no -> None annotation, and its fake_client parameter is unannotated. New
test methods are functions covered by the type-hint requirement.
9. Resource.__init__ lacks return type✓ Resolved
Description
The modified Resource.__init__ signature still has no explicit -> None return annotation. This
violates the requirement that every modified method declare a return type.
The modified NamespacedResource.__init__ signature still has no explicit -> None return
annotation. This violates the return-type requirement for modified methods.
12. Parametrized test docstring omits its Args section 📘 Rule violation⚙ Maintainability
Description
test_missing_client_detection takes source and expected but its one-line docstring has no
Args: section, so the parameters are undocumented. The other helpers in the same new file
(_import_aliases, _call_target, _missing_client_calls) do include Args: blocks, so this test
breaks the file's own convention. Maintainers reading the parametrize table will not find the
meaning of expected (the exact "<line>: <API>(...)" marker format) from the docstring.

Evidence
The function declares two parameters (source: str, expected: list[str]), and the checklist

other helper documents its arguments.

## Issue description
The new test `test_missing_client_detection` in `tests/test_examples_client.py` has parameters `source` and `expected` but its docstring is a single summary line with no `Args:` section. This departs from the Google-style docstring layout used by the other helpers in the same file.
## Fix Focus Areas

## Recommended Fix
Expand the docstring of `test_missing_client_detection` to keep the summary line and add an `Args:` section documenting `source` (Python source snippet to parse) and `expected` (the expected `"<line>: <API>(...)"` markers, empty when no client is missing). Keep the summary sentence ending with a period.

The commit rewrote NamespacedResource.__init__ so that name and namespace are the first positional
parameters again, with a bare * separator and client as a required keyword-only argument. This
matches the suggested fix: positional order for name/namespace is preserved, client is keyword-only,
and None is still rejected via MissingClientError in the base Resource constructor.
Description
NamespacedResource.__init__ moves client ahead of name and namespace, changing how existing
positional arguments bind. A custom subclass that inherits this constructor and passes a positional
name with client=client now raises a multiple-values TypeError, even though it supplies the
required client.
14. MissingClientError example never raises✓ Resolved
The example now passes client=None directly inside the try block, so the code path actually reaches
the MissingClientError handler; the misleading client=client if client else None conditional and the
fake client creation were removed.
Description
The try/except demo in error-handling.md builds Pod(client=client if client else None, ...) from a
freshly created fake client, so the None branch is unreachable for a live DynamicClient object and
the except MissingClientError handler never runs. The documented output line print(e) is
therefore never shown, and readers learn a misleading way to trigger the error.
_missing_client_calls accepts any positional argument on a classmethod call as the client, so
Secret.get("name") or Pod.get(some_value) passes even though the first parameter is not a
DynamicClient. The guard then reports clean for calls that would fail at runtime.
+ # Constructors take client as a required keyword; classmethods take it first,+ # because `get`/`list`/`delete_events` declare client as their first parameter.
Relevance
●● Moderate
Valid gap, but verifying the positional argument's type statically is subjective and no close
historical precedent exists either way.
ⓘ Recommendations generated based on similar findings in past PRs
Evidence
The condition is_classmethod and node.args treats the mere presence of a positional argument as
proof of a client, without checking what the argument is. The parametrized case
classmethod-positional-client only checks Secret.get(c) with a bare name, so nothing tests that
a non-client positional is rejected. Because the examples are not type-checked, a string or name
passed positionally to get would slip through.
Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The classmethod branch accepts any positional argument as the client, so non-client positional values pass the guard.
## Fix Focus Areas
- tests/test_examples_client.py[216-218]
## Recommended Fix
Restrict the positional exemption to a first argument that is a plain name or attribute whose identifier contains `client` (for example `c` is still needed, so document the convention or whitelist it). Add a parametrized case such as `Secret.get('name')` expecting a flagged result.

The demo now creates a fresh fake client via get_client(fake=True) inside demo_auto_validation() and
passes it to both Pod objects instead of the shared FAKE_CLIENT, so repeated invocations no longer
leave the pod in shared storage and conflict. This matches the suggested fix of creating a fresh
fake client inside the function.
Description
demo_auto_validation() now creates auto-validated-pod through the module-level FAKE_CLIENT
instead of a fresh fake client. Calling the demo twice in one process leaves the pod in that
client's storage after the first call, so the second call raises a resource conflict rather than
demonstrating successful validation.

entries and replaced them with 'client (DynamicClient): Mandatory k8s client; obtain it from
get_client().' style text in Resource.get, NamespacedResource.get,
Resource.get_all_cluster_resources, and Event.get/list/delete_events, and restructured
Returns/Raises sections into Google style. This addresses the docstring-format complaint, though the
summaries still lack terminal periods and parenthesized type entries remain, so the fix is partial
and differs from the suggested prompt.

The modified constructor adds name (str): Resource name instead of Google style's required `name:

The condition is_classmethod and node.args treats the mere presence of a positional argument as
proof of a client, without checking what the argument is. The parametrized case
classmethod-positional-client only checks Secret.get(c) with a bare name, so nothing tests that
a non-client positional is rejected. Because the examples are not type-checked, a string or name
passed positionally to get would slip through.
Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution
## Issue description
The classmethod branch accepts any positional argument as the client, so non-client positional values pass the guard.
## Fix Focus Areas
- tests/test_examples_client.py[216-218]
## Recommended Fix
Restrict the positional exemption to a first argument that is a plain name or attribute whose identifier contains `client` (for example `c` is still needed, so document the convention or whitelist it). Add a parametrized case such as `Secret.get('name')` expecting a flagged result.

The invalid Resource(name=..., *, client=...) snippet was replaced with a valid
Resource(name="my-resource", client=client) call, and the keyword-only contract is now explained
in prose as a signature rather than a call example, so copying the snippet no longer yields a
SyntaxError.
Description
The Resource(...) call example in resource-api.md places a bare *, marker inside a call's
argument list, which Python rejects at parse time. Readers who copy the snippet as written get a
SyntaxError before any client is created, and the snippet is an unchecked signature fragment, so the
docs guard does not catch it.
2. MissingClientError example never raises✓ Resolved
The example now passes client=None directly inside the try block, so the code path actually reaches
the MissingClientError handler; the misleading client=client if client else None conditional and the
fake client creation were removed.
Description
The try/except demo in error-handling.md builds Pod(client=client if client else None, ...) from a
freshly created fake client, so the None branch is unreachable for a live DynamicClient object and
the except MissingClientError handler never runs. The documented output line print(e) is
therefore never shown, and readers learn a misleading way to trigger the error.
Addressed: Addressed: normalized Resource.__init__ docstring to Google style (name: not name (str):), summary ends with period, and added Raises section.

Confirmed. All seven Qodo findings are addressed in the diff:
Resource.__init__ and NamespacedResource.__init__ now return None explicitly.
The affected tests have complete annotations, including FakeDynamicClient parameters and -> None returns.
_reject_removed_client_kwargs and Resource.__init__ use the requested Google-style docstring sections and formatting.
I also verified the changes in ocp_resources/resource.py:635-689 and tests/test_resource.py:101-165.
Both examples constructed resources without `client`, which now raises
MissingClientError, and contradicted the AGENTS.md rule this PR added.
examples/special_cases.py is left alone: it already fails to import
ocp_resources.network, which is a pre-existing defect.

The demo creates pods, so sharing the module-level FAKE_CLIENT left
'auto-validated-pod' behind and a second run in the same process failed
with a conflict instead of showing successful validation. Restores the
per-run `get_client(fake=True)` the demo had before the examples were
aligned on FAKE_CLIENT.

examples/ is excluded from every pre-commit hook, so a resource built
without client= there only fails when a reader runs the example - which is
how examples/role.py and examples/node_network_configuration_policy.py
were broken by the mandatory-client change while all checks stayed green.
The test statically walks examples/*.py, resolves every
Resource/NamespacedResource subclass in the package, and fails when a
constructor or get/list/get_all_cluster_resources/delete_events call omits
client=. examples/special_cases.py is skipped because it imports the
non-existent ocp_resources.network and is broken independently.

Review of the previous commit found the guard could pass vacuously:
- module import failures were swallowed, silently shrinking the set of
checked classes; they now fail the test, discovery walks subpackages and
a floor assertion catches partial discovery
- a missing examples/ directory produced a vacuous pass; the scan now
asserts it found files
- Event.get/list/delete_events were never checked (Event is not a
Resource subclass); they are now included
- a client passed positionally to a classmethod was reported as missing
- aliased and module-qualified imports, e.g. `from ocp_resources.role
import Role as R`, escaped detection; both are now resolved
- markers now carry line numbers, and the AST helpers have parametrized
unit tests instead of relying on the tree being clean
examples/special_cases.py imported `ocp_resources.network`, which stopped
existing in #1510, so it was the one file exempted from the check. It now
imports from ocp_resources.network_config_openshift_io and passes a client,
and the skip list is gone.

Third review round found four ways the detector could give the wrong
answer:
- the module-qualified branch matched on the last attribute name only, so
`self.Secret(...)` or `factory.Role(...)` was reported as a client-less
resource; the chain root must now be ocp_resources or an alias of it
- `Event()` was flagged even though only its classmethods need a client;
Event moved to a classmethod-only set
- walk_packages without onerror swallows a package import error, so its
submodules were never yielded and never recorded; failures are recorded
and the imported module count must equal the walked count
- the discovery guards were assert statements, stripped under python -O;
they now raise RuntimeError, and the floor moved from 200 to 240 with the
measured count recorded
Also reads example files as utf-8 and adds six parametrized cases covering
aliased classmethods, module aliases, Event construction and attribute
calls named like a resource.

The breaking change left docs/*.md and 30 docs snippets describing the old
API: client as optional (auto-created from kubeconfig with a FutureWarning),
dyn_client/config_file/config_dict/context still listed as resource
arguments, and MissingClientError undocumented.
- resource-api.md: client is required/keyword-only, the removed kwargs are
rejected, get()/get_all_cluster_resources() signatures match the code, and
a "Migrating to the Mandatory client" section covers the before/after
table plus the silent positional-misbinding risk for legacy subclasses
where client sat mid-signature (Secret, BridgeNetworkAttachmentDefinition)
- error-handling.md: MissingClientError section, import list and hierarchy
- connecting-to-clusters.md: no implicit client, and the FutureWarning
troubleshooting entry becomes the new TypeError entry
- creating-and-managing-resources.md, querying-resources.md,
working-with-events.md: stale client/dyn_client claims replaced
- 30 snippets across 6 pages now pass client=client, matching the
convention already used by common-patterns.md
tests/test_examples_client.py now scans fenced python blocks in docs/*.md
with the same AST detector (absolute line numbers, dedented list-nested
fences, signature fragments skipped with a parsed-block floor), so docs
drift fails the suite instead of shipping.
Rename test_07_migration_with_positional_client to
..._positional_args_with_keyword_client: it asserts keyword client, and the
docstring now says client travels through **kwargs, so nothing enforces it
at the type level.

Qodo round on 702a83b found two copy-paste defects in the new docs.
- resource-api.md: the constructor example put a bare `*,` inside a call,
which is a SyntaxError for anyone who copies it. It is now a valid
`Resource(name="my-resource", client=client)` call, with the real
keyword-only signature shown as prose instead of a fake call.
- error-handling.md: the MissingClientError demo built the client with
`client if client else None` from a live fake client, so the except
branch was unreachable and the documented message never printed. It now
passes `client=None`, plus a note that omitting `client` entirely raises
Python's own TypeError instead.
Both blocks now parse and are covered by the docs snippet guard.

Make the dynamic client mandatory across the wrapper API, make the breaking contract explicit at the call site, and bring the documentation and the docs snippets in line with it.

Pass a DynamicClient via client= from get_client() instead. The same rejection now reaches constructors, and unknown kwargs name the instantiated class (Pod() got unexpected keyword argument(s): ...).Resource.get_all_cluster_resourcesandEvent.getused to be generator functions whoseclient is Noneguard only fired on firstnext(); both now validate at call time and return an inner generator. The dead*argsescape hatch onget_all_cluster_resourcesis gone, so extra positionals fail immediately.__init__s (37 files) no longer declareclient=None; the client flows through**kwargs, which removes the false "optional" signal that let a missing-client call slip intoNodeNetworkConfigurationPolicy._get_port_from_nns.Raises:sections added to the six client-facing APIs;AGENTS.mddocuments both the required client and the removed kwargs; both runnable examples that the change would have broken (examples/role.py,examples/node_network_configuration_policy.py) now create a client.BREAKING CHANGE — every call site must pass an explicit client from
