feat(developer-portal-fe): render config.yaml from a pass-through values block - #345
Conversation
…ues block
The chart hand-wrote config.yaml and covered only 7 fields of the Developer
Portal config schema, with app.name pinned to a literal. Application name and
description, email-and-password auth, generic OAuth providers, db.ssl/schema/
pool and the rest were unreachable from Helm.
Render config.yaml from developerPortal.config instead, so any field the
application schema accepts is settable without a chart release. The connection
settings the chart owns — portal.url, the Secret-backed ${PORTAL_TOKEN} /
${DB_URL} / ${AUTH_SECRET} placeholders, app.baseURL and app.trustedOrigins —
are merged last and always win, so credentials cannot be moved into the
ConfigMap by setting them there and an untouched values.yaml renders the same
config as before.
Credentials belong in ${VAR} placeholders plus developerPortal.extraEnvVars;
the application substitutes them across every string value at startup. Both
are documented in the chart README.
Also add the chart to `ct lint` with a ci values file that exercises the whole
config surface, so a template change that breaks the pass-through fails CI.

📝 WalkthroughWalkthroughThe Developer Portal Helm chart now accepts a full application configuration, merges chart-owned connection settings with precedence, documents environment-variable secret injection, adds configuration examples, updates the chart version, and includes the chart in Helm linting. ChangesDeveloper Portal configuration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The chart now passes arbitrary application configuration through to runtime, but CI does not validate the rendered configuration against the application schema, so unsupported fields or types could reach deployment and cause startup failures. Merge should wait for schema validation in CI or explicit owner acceptance. Suggested reviewers: Important Pre-merge checks failedPlease resolve all errors before merging.

Pull request overview
This PR updates the developer-portal-fe Helm chart to render the application’s config.yaml from a new pass-through values block (developerPortal.config), allowing the full Developer Portal config schema to be configured via Helm while keeping chart-owned connection settings (and Secret-backed placeholders) authoritative.
Changes:
- Render
config.yamlfromdeveloperPortal.configand merge chart-owned connection settings last so they always win. - Document the pass-through model and the
${ENV}+extraEnvVarssecret-injection pattern in the chart README. - Add chart-testing coverage inputs and include this chart in CI linting.

- The Values table description says
developerPortal.configis rendered “verbatim” intoconfig.yaml, but the template merges chart-owned connection settings afterwards (overriding some paths). This description should match the actual behavior.

The chart pinned 0.5.7, whose config schema predates db.schema, auth.adminUserIds, auth.twoFactor, auth.genericOAuthProviders, auth.sso and the app.applicationDetail / app.apiHub / app.signUpConsentLabel group — those fields are now reachable from values but the pinned image would drop them. 0.14.0 keeps the container contract unchanged (same port, entrypoint and /app/apps/site/config.yaml search path), and brings one breaking change: auth.secret must be at least 32 characters. Both it and the one config field to avoid on this version (auth.socialProviders, whose upstream schema is mis-declared and fails to parse) are documented in the chart README, and the ci values file leaves that field out.
…er the config block "Verbatim" read as "no key is touched", which is wrong — the chart-owned connection settings are merged over developerPortal.config.

Problem
charts/developer-portal-fe/templates/configmap.yamlhand-wroteconfig.yamland only covered 7 fields of the Developer Portal config schema, withapp.namepinned to a literal. Application name/description, email-and-password auth, generic OAuth providers,db.ssl/db.schema/db.pooland the rest of the schema were unreachable from Helm — the documented customization steps could not be applied to a Helm deployment at all.Implementation
config.yamlis now rendered from a newdeveloperPortal.configblock, passed through verbatim, so any field the application's config schema accepts is settable without a chart release. Mirroring the schema as per-field.Valueskeys was rejected — it would drift every time the application adds a field.The connection settings the chart owns are merged in last and always win over
developerPortal.config:portal.url.Values.portal.urlportal.token${PORTAL_TOKEN}(Secret)db.url${DB_URL}(Secret)auth.secret${AUTH_SECRET}(Secret)app.baseURL,app.trustedOrigins.Values.app.*Credentials such as
auth.genericOAuthProviders[].clientSecretstay out of the ConfigMap: the application substitutes${VAR}/${VAR:default}across every string value ofconfig.yamlat startup, so the documented pattern is a placeholder indeveloperPortal.configplus the real value injected throughdeveloperPortal.extraEnvVars. The chart README documents the pass-through model, the chart-owned keys, and this secret-injection pattern.The application is also bumped 0.5.7 → 0.14.0. The pinned 0.5.7 schema predates
db.schema,auth.adminUserIds,auth.twoFactor,auth.genericOAuthProviders,auth.ssoand theapp.applicationDetail/app.apiHub/app.signUpConsentLabelgroup, so those fields would be reachable from values but dropped by the running application.Behavior change
values.yamlrenders aconfig.yamlthat parses to exactly the same document as before (key order and quoting differ, since the body is nowtoYamloutput). Settingportal.token/db.url/auth.secretunderdeveloperPortal.confighas no effect — the Secret-backed placeholders win.auth.secretto be at least 32 characters; a shorter secret now fails validation at startup. Rotating it signs existing users out. The chart README carries this as an upgrade note.auth.socialProvidersis the one config field to avoid on 0.14.0 — its schema is mis-declared upstream (z.object(z.any()), fixed after 0.14.0) and setting it makes config parsing throw.auth.genericOAuthProviderscovers the same ground and is unaffected.Testing
ct lintdid not cover this chart, so it is added to the lint list along withci/full-config-values.yaml, which exercises the whole config surface — a template change that breaks the pass-through now fails CI.Verified locally:
apps/site/src/lib/config/schema.ts);ci/render both load successfully in the realapi7/api7-ee-developer-portal-fe:v0.14.0image (preflight gets past config validation to the portal connection check), and a shortauth.secretfails there with the documented message;developerPortal.configforportal.url/portal.token/db.url/auth.secret/app.baseURL/app.trustedOriginsdo not reach the rendered ConfigMap;helm lint,ct lint, andhelm-docs(v1.13.1, the version CI checks against) all pass.
