fix(dashboard, foundationdb): show the connection ConfigMap to tenants by yankawai · Pull Request #4612 · cozystack/cozystack

europrinter (yankawai) · 2026-09-30T14:42:30Z

What this PR does

Since #4148 a tenant may read the <release>-config ConfigMap that holds the FoundationDB cluster file, but the console has no view for ConfigMaps, so the connection string was still reachable only with kubectl.

Chart:

<release>-resourcemap is rendered regardless of monitoring.enabled, because the console now reads it;
the tenant Role grants get, list and watch on <release>-resourcemap next to <release>-config, still by resourceNames, with no wider ConfigMap access.

Console:

the application page gets a ConfigMaps tab when the application's resource map lists at least one ConfigMap in the same namespace;
each listed ConfigMap is read and watched with a metadata.name field selector, which RBAC checks against resourceNames, so a tenant never needs list on all ConfigMaps;
values are shown as plain text with a copy button, the cluster file needs no decoding;
a resource map that is missing or forbidden hides the tab, a listed ConfigMap that cannot be read shows the API error instead of looking empty, and a malformed map or an invalid name is reported.

The tab is generic, but today only FoundationDB ships a resource map, so it is the only application that gets it.

#3490 keeps monitoring.enabled as the switch for the resource map and asks whether the map should render unconditionally. This PR answers that for FoundationDB by rendering it always, so the wording in #3490 would need to follow if both land.

Tests: helm unittest for the chart (6 tests), tsc --noEmit, vitest run (438 tests in 60 files) and eslint on the changed files pass. The new tests cover reading only the listed names in the active namespace, the watch, copying, a clipboard failure, a read denial, and malformed maps. The chart renders with monitoring.enabled true and false.

Downstream repositories

Walked the trigger map against the diff: it changes a FoundationDB chart template and its test, and the console. No values.yaml, values.schema.json, README, CRD or hack/ file is touched. The website FoundationDB page is generated from the chart README and says nothing about connecting, and the Terraform provider does not read these ConfigMaps. The console is vendored in this repository.

Release note

fix(dashboard, foundationdb): the application page shows the FoundationDB connection ConfigMap with the cluster file to tenants who may read it

Summary by CodeRabbit

New Features
- Application details now include a ConfigMaps tab when configuration maps are available. View their values and copy them to the clipboard.
- The tab displays loading, empty, unavailable, and error states.
Bug Fixes
- The resource map remains available when monitoring is disabled, and its access permissions are included.

The resource map is the only object that names the connection ConfigMap for a client such as the dashboard. It was rendered only with monitoring enabled, and the tenant role could not read it, so a tenant session had no way to find the ConfigMap it is allowed to read.

FoundationDB keeps its connection string in a ConfigMap that its operator writes, and tenants may read it, but the console had no view for ConfigMaps. Tenant roles grant ConfigMaps by name only, so the tab takes the names from the application's resource map and reads each one with a metadata.name field selector, which RBAC checks against resourceNames. An application without a readable resource map shows no tab, while a listed ConfigMap that cannot be read is reported instead of looking empty.

📝 Walkthrough

Walkthrough

The FoundationDB chart now renders its resource map regardless of the monitoring setting and grants access to it. The dashboard reads the resource map to discover application ConfigMaps, then displays their values in a new application-page tab.

Changes

FoundationDB ConfigMap dashboard

Layer / File(s)	Summary
Resource-map availability and access `packages/apps/foundationdb/templates/dashboard-resourcemap.yaml`, `packages/apps/foundationdb/tests/dashboard-resourcemap_test.yaml`	The resource-map ConfigMap now renders without the monitoring condition. The dashboard-resources Role grants access to both the resource map and cluster configuration. Tests check the resource names and document count.
ConfigMap discovery `packages/system/dashboard/images/console/apps/console/src/routes/detail/use-app-configmaps.ts`, `packages/system/dashboard/images/console/apps/console/src/routes/detail/ConfigMapsTab.test.tsx`	The new hook reads and parses the release resource map to find matching ConfigMap names. Parsing validates resource kinds, namespaces, and names. Tests cover filtering, duplicates, malformed input, and invalid names.
Application ConfigMaps view `packages/system/dashboard/images/console/apps/console/src/routes/detail/ApplicationDetailPage.tsx`, `packages/system/dashboard/images/console/apps/console/src/routes/detail/ApplicationDetailPage.test.tsx`, `packages/system/dashboard/images/console/apps/console/src/routes/detail/ConfigMapsTab.tsx`, `packages/system/dashboard/images/console/apps/console/src/routes/detail/ConfigMapsTab.test.tsx`	The application page adds a ConfigMaps tab when names are found or discovery reports an error. The tab reads each named ConfigMap and displays its values, read state, and copy status. Tests cover tab visibility, reads, errors, and copying.

Merge Risk: 🔵 Low · up to 2fa7f

The ConfigMaps view enables tenants to read and copy application configuration. A forbidden resource-map refetch can leave the tab visible instead of hiding it; this narrow state-handling issue permits merging with owner awareness and follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 2fa7f

The added access remains restricted to named application ConfigMaps, and the dashboard uses namespace-scoped requests and plain-text rendering. No privilege escalation was established. Permission-change handling and effective deployment identity remain incompletely validated.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The added authorization exposes application resource-map metadata to subjects already selected by the tenant use-level RoleBinding, including inherited ancestor subjects. The Role remains namespaced and release-name-restricted; existing access to the connection configuration is not broadened.

Trust Boundaries and Controls

inferred — A modified resource map can suggest other valid ConfigMap names, but cannot itself grant access: subsequent requests remain in the active namespace and are subject to Kubernetes authorization. Explicit cross-namespace entries are discarded, unsafe names are rejected, and returned values are not interpreted as executable markup.
inferred — The inspected entrypoint and proxy configuration support the documented model in which the apiserver authorizes the user's identity rather than a privileged dashboard credential. The effective gatekeeper configuration and live identity propagation were not independently verified.

Resilience and Maintainability Implications

inferred — Discovery parses cached data before suppressing 403/404 errors, so previously discovered names may remain visible after a failed refetch. This is an availability-state inconsistency, not an established authorization bypass: individual reads still use named requests, and child read errors take precedence over displaying values.

Hardening Proposals

proposed — Define a permission-revocation policy for cached discovery metadata, including successful discovery followed by denial, deletion, or watch recovery. Align visible names with that policy without treating resource-map membership as authorization.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear discovery results when the resource map becomes forbidden.

If discovery succeeds and a later refetch returns 403, TanStack Query retains the previous successful data. (tanstack.com)

This return suppresses the query error but preserves parsed.names. ApplicationDetailPage therefore keeps the ConfigMaps tab visible. A cached parsing error also keeps the tab visible. This contradicts the stated requirement to hide the tab when the resource map is forbidden.

Return empty names and no error when unavailable is true.

Proposed fix

+ if (unavailable) return { names: [], isLoading: query.isLoading, error: null } return { ...parsed, isLoading: query.isLoading, error: parsed.error ?? (unavailable ? null : query.error) ?? null }

europrinter (@yankawai) LGTM. Since #4148 a tenant may read the FoundationDB cluster file, and this makes the application page show it without a new discovery mechanism.

Nothing on main reads <release>-resourcemap, and FoundationDB is the only chart that renders one, so the console becomes its first consumer. The other way would be a configMaps selector on ApplicationDefinition next to secrets and services. That is a new CRD field plus a server-side projection for one application, so I prefer this.

On access: the only new grant is the resource map, and it holds object names only. <release>-config was already tenant-readable. Both stay behind resourceNames, and the metadata.name field selector is what lets list and watch pass that check. Rendering the map without monitoring.enabled changes nothing for monitoring, because the WorkloadMonitor template keeps its own switch and nothing else selects on the dashboard-resourcemap label.

The branch merges into current main cleanly. helm unittest passes, and so do vitest for src/routes/detail, tsc --noEmit and eslint on the changed files. Dropping the field selector in ConfigMapItem fails four tests. Dropping the namespace filter in configMapNames fails the parsing test.

Non-blocking: #3490 edits the same template, so whichever lands second needs a rebase.

…adable (#4789) ## What this PR does Follow-up to #4612. The ConfigMaps tab takes its names from the application's resource map. React Query keeps the last successful list when a refetch fails, so when the resource map became forbidden or went away after a successful read, `useApplicationConfigMaps` went on parsing the old copy. The tab stayed with the old names, every listed ConfigMap showed an access error, and a malformed map kept its old error. A map that is unreadable from the start already hid the tab. Now a 403 or 404 on the resource map drops the names and the error whether or not an earlier read succeeded, so the tab goes away in both cases. Any other error is still shown on the tab, as before. The new tests are a page test with stale resource map data next to a 403, and hook tests that read the map and then refetch it with 403 and with 404, plus a malformed map followed by a 403. All four fail on main and pass here. `pnpm typecheck`, `pnpm test` (451 tests in 62 files) and `pnpm lint` pass. ### Screenshots No visual change. Once the resource map is unreadable, the page looks the same as for an application whose map was never readable, with no ConfigMaps tab. The tab itself is shown in #4612. ### Downstream repositories Walked the trigger map against the diff. It touches only the console hook that reads the resource map and its tests. No chart, values, schema, CRD or `hack/` file changes, and the console is vendored in this repository. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note fix(dashboard): the ConfigMaps tab now goes away when the application's resource map stops being readable, instead of keeping the names from the last successful read ```  ## Summary by CodeRabbit * **Bug Fixes** * ConfigMaps are no longer displayed when access to the resource map is forbidden or the resource map is missing. * The ConfigMaps tab is excluded when the resource map cannot be accessed.
