🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secret safely. Learn here the best practices.
- Revoke and rotate this secret.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
🦉 GitGuardian detects secrets in your source code to help developers and security teams secure the modern development process. You are seeing this because you or someone else with access to this repository has authorized GitGuardian to scan your pull request.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The documentation currently includes examples and compatibility guidance that may fail when followed, including mismatched storage backends and release claims that do not support the documented fields. Additional open explanations may also mislead users about certificates, refresh timestamps, copy-on-write behavior, retained resources, snapshot output, and refresh Jobs, so these issues should be corrected or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Inline comments:
In `@docs/guides/postgres/branch/customization/examples/dev-branch-vsc.yaml`:
- Around line 7-17: Update the volumeSnapshotClassName in the customization
example to use a snapshot class backed by the same CSI driver as the gp3
storageClassName, or change the source and target storage classes consistently
to TopoLVM if that is the intended guide scenario.
In `@docs/guides/postgres/branch/customization/index.md`:
- Around line 357-358: Update the row-count example near the kubectl psql
command so its expected value is independent of the earlier source insert: use
1001, unless this section explicitly adds that mutation as a prerequisite. Keep
the surrounding customization steps unchanged.
- Line 14: Update the introductory link in the documentation to replace the
generic “here” text with descriptive text identifying the KubeDB getting-started
or README destination, while preserving the existing link target.
In `@docs/guides/postgres/branch/overview/index.md`:
- Line 14: Replace the non-descriptive “here” link text with “the KubeDB setup
guide” at docs/guides/postgres/branch/overview/index.md:14,
docs/guides/postgres/branch/same-cluster/index.md:14, and
docs/guides/postgres/branch/same-cluster/index.md:30, preserving the existing
destination URL.
- Around line 62-63: Correct the inheritance wording in
docs/guides/postgres/branch/overview/index.md lines 62-63 by stating that source
fields are inherited by default, with overrides from spec.target plus
spec.configSecret, spec.resetRootPassword, and spec.postActions. Update
docs/guides/postgres/branch/same-cluster/index.md lines 225-231 to replace
“Everything else” with the same default-inheritance and exception wording; both
sites require documentation changes.
In `@docs/guides/postgres/branch/same-cluster/index.md`:
- Around line 441-469: The teardown verification uses resources not created by
this walkthrough. Update the deletion command and all subsequent resource checks
to consistently reference the demonstrated dev-branch and dev-postgres
resources, including the PVC, Secret, Job, and VolumeSnapshot checks, and remove
the post-action Job check unless the walkthrough creates it.
- Around line 475-476: Correct the sample outputs in the branch same-cluster
guide: the initial source count remains 1000, the source-only insert makes the
source 1001, and dev-branch-keep created afterward must also start at 1001.
Update the outputs at both referenced command examples consistently, or add the
missing insert only if the documented workflow requires a 1002 count.
- Around line 31-33: Update the manual Branch CRD installation command in the
guide to reference the CRD file from the installed KubeDB release or its
matching version tag instead of refs/heads/master, keeping the command
compatible with the release installed earlier in the guide.
In `@docs/guides/postgres/concepts/branch.md`:
- Line 13: Update the introductory link text in the “New to KubeDB?” sentence to
describe its destination instead of using the generic “here” label, while
preserving the existing /docs/README.md target.
- Around line 118-121: Update the issuerRef documentation in the branch concepts
guide to distinguish cert-manager scope accurately: an Issuer must exist in the
target namespace, while a ClusterIssuer is cluster-scoped and is not
namespace-bound. Preserve the existing behavior details about fresh
certificates, TLS-enabled sources, and when issuerRef is ignored.

finalizer cleanup before showing the target Postgres, Secret, PVC, and
VolumeSnapshot deletion results. Also update the dev-branch-keep section at

- Line 268: Update the command examples around the kubectl snippets and the
corresponding sections near the other affected locations so Markdown command
fences comply with MD014: remove the leading “$” prompt from commands, or place
each command and its output together in one code fence. For the snippet with no
output, remove the unnecessary command fence or adjust it to contain only the
command without a prompt.
- Line 471: Add the topolvm-vsc-explicit VolumeSnapshotClass prerequisite to

and document the same prerequisite for

class, and apply the same change to both occurrences.
- Around line 210-211: Update docs/guides/postgres/concepts/branch.md lines

- Around line 40-42: Update the customization example around the customer UPDATE
so it either masks full_name along with email and phone, or narrows the
accompanying anonymization wording and verification output to only the fields
actually changed. Ensure the documented result does not imply that unchanged
personal-data columns are protected.

failure row to account for the 600-second ttlSecondsAfterFinished retention
window, or remove that setting from the debugging example so failed Job logs
remain available for investigation.
- Around line 525-527: Update the cleanup commands in the tutorial to delete
only the named Branch resources created by this section, including
dev-branch-masked, dev-branch-refresh, dev-branch-xns, dev-branch-ha, and
dev-branch-vsc, instead of using --all. Remove ns dev only when it is
tutorial-created, and replace any immediate delete --wait=false cleanup with a
delete followed by kubectl wait --for=delete.

- Qualify the copy-on-write claim in the Branch concept doc: restores depend on the CSI driver supporting copy-on-write, not guaranteed universally. - Align the concept doc's example storageClassName with its volumeSnapshotClassName (topolvm-provisioner-thin instead of gp3). - Describe status.resources as references, moving teardown behavior into the policy-specific text (only Delete removes everything; Orphan keeps authSecret/clonedPVCs). Add the missing configSecret entry to the overview page's resource list. - Also mask full_name in the post-action anonymization example, so the "anonymized" claim and its verification output do not leave an unredacted personal-data column in view. - Add kubectl wait --for=condition=Ready steps after each branch/database apply in the refresh, cross-namespace, HA, and VolumeSnapshotClass examples, before commands that depend on readiness. - Scope the customization guide's cleanup to the branches it actually created, instead of `branch --all`, so it cannot sweep up an unrelated branch left in the same demo namespace by another walkthrough. - Drop the "byte-for-byte" wording from the same-cluster walkthrough's verification step: the source stays writable during the snapshot, so only row presence is actually being proven.

- Use jsonpath-as-json instead of jsonpath for the status.snapshot example, so the shown output matches what the command actually prints for a structured field. - Fix the PostActionFailed troubleshooting row: the post-action Job is only named <target>-post-action on the first run; a refresh's Job is <target>-post-action-gen<N>. Point at the label selector to find the actual Job instead of assuming the fixed name. - Qualify copy-on-write/block-sharing claims by CSI driver capability in the overview and same-cluster pages, consistent with the concept doc's wording; keep the write-isolation and "not a backup" conclusions, which hold regardless of driver. - Qualify status.resources in the same-cluster walkthrough the same way already done in the concept doc and overview page: it lists references, not a blanket "what teardown removes" (Orphan keeps most of it). - Correct the issuerRef rationale: a certificate is bound to its database's own identity, so a branch needs a fresh one even in the source's own namespace — namespace scope only affects which Issuer is visible to reference. - Clarify that lastRefreshTime/lastSuccessfulRefreshTime/refreshGeneration cover the initial one-shot copy, not only later scheduled refreshes. - Cross-cluster doc: note the courier/CRD version dependency shared with spec.postActions, and use one consistent CSI driver (topolvm-provisioner-thin) across the source and target StorageClass in the example instead of implying two unrelated backends.

Point at the label selector to find the actual Job instead of assuming the fixed name. - Qualify copy-on-write/block-sharing claims by CSI driver capability in the overview and same-cluster pages, consistent with the concept doc's wording; keep the write-isolation and "not a backup" conclusions, which hold regardless of driver. - Qualify status.resources in the same-cluster walkthrough the same way already done in the concept doc and overview page: it lists references, not a blanket "what teardown removes" (Orphan keeps most of it). - Correct the issuerRef rationale: a certificate is bound to its database's own identity, so a branch needs a fresh one even in the source's own namespace — namespace scope only affects which Issuer is visible to reference. - Clarify that lastRefreshTime/lastSuccessfulRefreshTime/refreshGeneration cover the initial one-shot copy, not only later scheduled refreshes. - Cross-cluster doc: note the courier/CRD version dependency shared with spec.postActions, and use one consistent CSI driver (topolvm-provisioner-thin) across the source and target StorageClass in the example instead of implying two unrelated backends.

Switch every example from the `gp3` StorageClass to `topolvm-provisioner-thin`, so the StorageClass, the VolumeSnapshotClass and the CSI driver are one consistent chain. `gp3` was an EKS-era fixture name aliased onto TopoLVM on the test cluster, so the docs showed an AWS EBS name whose provisioner printed `topolvm.io`. Every command output was re-captured from a full re-run on the new class. Fix three regressions introduced when the guide was split into a walkthrough and a customization page: - the Delete-policy section tore down `dev-branch-masked`, which had moved to the customization page, so its commands returned NotFound and demonstrated nothing - row counts read 1002 where the walkthrough's own arithmetic gives 1001; the extra row came from the refresh section, which also moved - the cross-namespace row count contradicted the "each section is independent" claim. The sections do run in sequence, so the claim was corrected rather than the number Other corrections: - post-action Jobs carry `courier.kubedb.com/branch`, not `app.kubernetes.io/instance`; the troubleshooting selector matched nothing - spell out that `resetRootPassword` and `postActions` also change what the branch inherits, not only the fields under `spec.target` - separate `Issuer` (namespace-scoped, must live in the target namespace) from `ClusterIssuer` in the CRD reference - add a `kubectl explain branch.spec.postActions` check so a reader with a pre-rename Branch CRD finds out before following the guide Signed-off-by: Anisur Rahman <anisur@appscode.com>

- Qualify the copy-on-write claim in the Branch concept doc: restores depend on the CSI driver supporting copy-on-write, not guaranteed universally. - Align the concept doc's example storageClassName with its volumeSnapshotClassName (topolvm-provisioner-thin instead of gp3). - Describe status.resources as references, moving teardown behavior into the policy-specific text (only Delete removes everything; Orphan keeps authSecret/clonedPVCs). Add the missing configSecret entry to the overview page's resource list. - Also mask full_name in the post-action anonymization example, so the "anonymized" claim and its verification output do not leave an unredacted personal-data column in view. - Add kubectl wait --for=condition=Ready steps after each branch/database apply in the refresh, cross-namespace, HA, and VolumeSnapshotClass examples, before commands that depend on readiness. - Scope the customization guide's cleanup to the branches it actually created, instead of `branch --all`, so it cannot sweep up an unrelated branch left in the same demo namespace by another walkthrough. - Drop the "byte-for-byte" wording from the same-cluster walkthrough's verification step: the source stays writable during the snapshot, so only row presence is actually being proven.

Add a reference page for branching a PostgreSQL database into a different Kubernetes cluster over Open Cluster Management (spec.target.clusterName, Initiator/Creator roles, the BranchWork/ManifestWork relay through the hub, prerequisites, refresh, and deletion). Written as a reference rather than a hands-on walkthrough: cross-cluster branching needs an OCM hub and two spokes sharing a storage backend, which this doc set does not assume the reader has, so it contains no captured command output. Cross-link it from the Overview's mode table and Next Steps, the same-cluster walkthrough's Next Steps, the customization guide's intro, and the Branch CRD reference's spec.target.clusterName/status.mode fields.

The CI kind cluster installed courier's migration CRDs but never the Branch or BranchWork CRDs, so the codespan schema checker failed every "kind: Branch" example in the branching docs with "no matches for kind Branch in version courier.kubedb.com/v1alpha1" — not a problem with the examples themselves. Verified locally: with these two CRDs installed on a kind cluster, every Branch example under docs/guides/postgres/branch (including the embedded YAML in cross-cluster/index.md, customization/index.md, same-cluster/index.md, and concepts/branch.md) passes `kubectl apply --dry-run=server`.

Not this structure.
We should write the things in https://github.com/kubedb/docs/tree/master/docs/operatormanual in a common way like already done for recommendation. Then the DB pages should be simple, not concept-heavy & directly actionable.
