MON-4654: allow query parameters in remote write URLs - #3124
Allow query parameters in ClusterMonitoring remoteWrite URLs by removing only the CEL prohibition on queries. Preserve validation for HTTP/HTTPS schemes, non-empty hostnames, length, fragments and user information.
Update field documentation and regenerate CRD, Swagger, OpenAPI and payload schemas with make update. Add eight admission cases covering valid simple, multiple, escaped and HTTP query parameters and rejected scheme, hostname, fragment and user-information variants.
Validation: full make update completed; all eight focused admission tests passed using the CI Go 1.26 image.

Walkthrough
RemoteWriteSpec.URL validation now permits query parameters. The API documentation and CRD description reflect this change, and the rule that rejected query strings has been removed. URL syntax, HTTP/HTTPS schemes, hostname, length, fragment, and user-information constraints remain. New create-test cases check accepted query-bearing URLs and rejected URLs that violate the remaining constraints.
Priority: Normal
Merge Risk: Minimal · up to d52e4
Remote-write URLs can now include query parameters without an identified regression in the remaining URL restrictions. The change is ready for normal merge checks.

Full details: Docstring Coverage
Explanation
No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files. (2 skipped: 2 unsupported.)
Full details: Stable And Deterministic Test Names
Explanation
The added admission test titles in config/v1alpha1/tests/clustermonitorings.config.openshift.io/ClusterMonitoringConfig.yaml:7-204 use static descriptions such as Should accept remoteWrite URL simple query and Should reject remoteWrite URL unsupported scheme with query. They contain no pod names, timestamps, UUIDs, node or namespace names, IP addresses, generated identifiers, or legacy metadata tokens. The URL values remain in test bodies, not titles.
Full details: Test Structure And Quality
Explanation
The PR adds 12 declarative onCreate admission cases in config/v1alpha1/tests/.../ClusterMonitoringConfig.yaml; it does not add standalone Ginkgo It blocks. Each case tests one URL behavior and uses the repository's existing table-test pattern. The shared Ginkgo harness installs the CRD in BeforeEach, deletes created resources and uninstalls the CRD in AfterEach, and uses a timeout for its Eventually wait. The new cases add no pod, deployment, or indefinite wait operation. They provide explicit expected objects or expected error substrings. ote.Informing() is not applicable to these YAML table entries.
Full details: Microshift Test Compatibility
Explanation
PASS: The pull request adds YAML-driven CRD admission cases, not MicroShift e2e tests. The changed cases use config.openshift.io/v1alpha1ClusterMonitoring objects in config/v1alpha1/tests/...yaml. The repository harness runs these through a local controller-runtime envtest API server and generated DescribeTable entries, so the change does not add a MicroShift-running Ginkgo e2e test or an unguarded MicroShift API dependency.
Full details: Single Node Openshift (Sno) Test Compatibility
Explanation
The pull request adds YAML onCreate admission fixtures in config/v1alpha1/tests/.../ClusterMonitoringConfig.yaml and updates validation and generated schemas. It does not add Ginkgo e2e tests or It, Describe, Context, or When blocks. The new cases only validate URL admission and make no multi-node or HA assumptions.
Full details: Topology-Aware Scheduling Compatibility
Explanation
PASS. The pull request changes only URL validation, generated schemas, documentation, and admission test data. The diff adds or modifies no deployment manifests, operator controllers, pod specifications, replica settings, affinity, topology spread constraints, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.
Full details: Ote Binary Stdout Contract
Explanation
The pull request changes only URL validation, generated schema documentation, and YAML admission cases. No changed process-level code contains main/suite setup, logging, or stdout writes. The added tests are admission cases, not OTE process setup.
Full details: Ipv6 And Disconnected Network Test Compatibility
Explanation
PASS: The pull request adds declarative admission-test fixtures in a YAML file, not Ginkgo e2e tests. The diff contains no new It(), Describe(), Context(), or When() blocks. The example URLs use remote.example.com only as validation data; the tests do not connect to that host or any external service. No IPv4-only assumption or disconnected-network requirement is introduced.
Full details: No-Weak-Crypto
Explanation
The pull request changes only remote-write URL validation, documentation, generated schemas, and admission cases. The diff adds no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom cryptography, or secret/token comparisons.
Full details: Container-Privileges
Explanation
PASS. The pull request changes URL validation, admission test cases, and generated schema documentation only. The reviewed diff adds no privileged containers, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root execution settings.
Full details: No-Sensitive-Data-In-Logs
Explanation
The pull request changes URL validation, documentation, generated schemas, and admission fixtures only. The diff adds no logging calls or log-message changes. The email-like value and password text appear only as synthetic validation-test URLs and example error/documentation text; they are not emitted to logs.

it rejects user information only within the URL authority, while allowing `@` in
query values. Add the query-value example to the admission fixtures and

Included review availability: This review used your included allowance. Your plan provides up to 12 included reviews per hour; 11 remain after this review.
Reason: PR modifies ClusterMonitoring CRD validation (config/v1alpha1): removes the CEL rule prohibiting query parameters in remoteWrite URLs and narrows the user-info @ regex from .*@.* to ^[^:]+://[^/?#]*@ (authority-only). Payload manifest payload-manifests/crds/0000_10_config-operator_01_clustermonitorings.crd.yaml updated. Change is strictly additive (no previously valid URLs become invalid). 12 admission test cases added and exercised in first-stage integration/verify-crd-schema (passed). Selected: - e2e-aws-ovn: Default e2e validates CRD payload installation and cluster operation with the modified manifest. - e2e-aws-ovn-techpreview: ClusterMonitoringConfig is behind a TechPreview feature gate; this job enables it so the modified CEL rules are exercised at runtime. - e2e-upgrade: CRD payload is replaced during upgrade; confirms the validation change (additive relaxation) applies cleanly. Not selected: - vSphere jobs: Annotation targets config/v1/types_infrastructure.go and VSphere CRDs — no file in this PR matches; no behavioral relevance to monitoring CRD validation. - e2e-azure, e2e-gcp: CRD CEL validation is cloud-independent; AWS covers the installation path. - HyperShift jobs: ClusterMonitoring CRD deploys identically; standard e2e covers CRD installation. - Serial jobs: Disruptive/serial operations have no distinct interaction with monitoring URL validation rules. - customnoupgrade: Same CRD path as standard e2e-aws-ovn. - upgrade-out-of-change, minor-e2e-upgrade-minor: e2e-upgrade covers the CRD update axis; the validation change is strictly additive.
