Configuration

Profiles

Profiles are defined via Spring application-*.yml:

  • local: local developer settings (src/main/resources/application-local.yml)

  • mysql: MySQL settings with env overrides (src/main/resources/application-mysql.yml)

  • oracle: Oracle settings with env overrides (src/main/resources/application-oracle.yml)

Select the active profile with SPRING_PROFILES_ACTIVE (for example local, mysql, oracle).

Core HTTP settings

  • Context path: server.servlet.context-path=/configs-service (src/main/resources/application.yml)

  • Swagger UI: springdoc.swagger-ui.doc-expansion=none

Hazelcast client settings

The Hazelcast client is configured by ft-cache:

  • cache-config.path – defaults to classpath:; the effective resource is ${cache-config.path}hazelcast-client.yaml.

    • In container environments, CACHE_CONFIG_PATH is the typical env var name used to provide this value (Spring relaxed binding maps it to cache-config.path).

  • HZ_MEMBERS – overrides members list (comma/space separated).

    • If a member entry does not contain a port, :5701 is appended by the ft-cache resolver.

  • cache.is-server – when true, starts an embedded Hazelcast member from ${cache-config.path}hazelcast.yaml (not used for this service in production).

    • In container environments, CACHE_IS_SERVER is the typical env var name.

Production note: cluster-name is configured as dev.

Database settings

Database configuration is profile-specific:

  • mysql profile reads DB settings from application-mysql.yml (env overrides supported).

  • oracle profile reads DB settings from application-oracle.yml (env overrides supported).

See Environment variables for the full env var matrix with verified defaults and examples.

JWT and cookies

JWT and cookie settings come from the active profile YAML and can be overridden via environment variables.

See Environment variables for JWT_* and COOKIE_* inputs, defaults, and usage notes.

Mail

Spring Mail is configured in profile YAMLs (host, port, username/password, TLS flags) and used for:

  • user onboarding emails (mail/registration.html)

  • user deletion flows (auth/deletion/*)

Delivery modes (online / offline)

Email delivery is controlled by MAIL_MODE (property mail.mode), evaluated in MailDeliveryStatus from mail.mode plus Spring MailProperties. Values are case-insensitive; a blank or unknown value falls back to AUTO with a warning log. The supported values are AUTO and OFFLINE.

  • AUTO (default) — infers the mode from SMTP config: treated as OFFLINE when MAIL_HOST, MAIL_USERNAME, or MAIL_PASSWORD are not all set (non-blank); when they are all set it attempts email, but degrades to offline behaviour at runtime if the SMTP server is unreachable (see Runtime fallback below).

  • OFFLINE — never send email.

At startup the service logs the resolved mode, for example:

Mail delivery: mode=AUTO, smtpConfigured=false, effectiveOffline=true

Offline behavior

When offline (chosen explicitly via OFFLINE, inferred by AUTO, or reached at runtime when a configured SMTP server is unreachable):

  • Create user (POST /api/admin/users) and reset password (POST /api/admin/users/{id}/reset-password): the temporary password is not emailed. It is returned in the API response (passwordDelivery=RETURNED) so an admin can deliver it out-of-band.

  • User deletion request (POST /api/admin/users/{id}/deletion/request): OTP email confirmation is disabled. No OTP/token is issued and the response carries otpRequired=false, signalling the UI to show a plain confirmation. The account is still deleted in the /deletion/confirm step, called without a token/OTP (allowed only while OTP delivery is unavailable — configured offline or SMTP unreachable).

Online behavior

When online (AUTO with SMTP configured and reachable):

  • Temporary passwords are emailed; create/reset responses carry passwordDelivery=EMAIL and temporaryPassword=null.

  • Deletion issues an OTP intent and emails the OTP to the initiating admin’s address, returning otpRequired=true with token/expiry/otpLength/attemptLimit; the admin then calls /deletion/confirm with the OTP.

Because the OTP is sent to the initiating admin, that admin must have an email in online mode. Otherwise the deletion request fails with error code USER_DELETION_EMAIL_REQUIRED ("User email is required to request account deletion"). This email check applies only in online mode.

Runtime fallback on send failure

Under AUTO with SMTP configured, if the server is unreachable or a send throws, delivery degrades to the offline behaviour instead of erroring:

  • Create/reset password delivery degrades to passwordDelivery=RETURNED.

  • User deletion degrades to the no-OTP path: the request returns otpRequired=false and the account is deleted in the tokenless confirm step. The deletion confirm probes SMTP reachability (MailDeliveryStatus.isOtpConfirmationAvailable()) so it accepts a tokenless confirm when the server is down, since it has no OTP to send.

To keep this prompt, the JavaMail connect/read/write timeouts are fixed at 5000 ms (previously infinite, which could hang the request thread). They are configurable via spring.mail.properties.mail.smtp.connectiontimeout, .timeout, and .writetimeout.

See Security — User secret delivery for the rationale behind returning secrets in API responses.

Email template system

Email templates use table-based HTML for maximum email client compatibility:

  • Mobile-responsive — fluid width adapts to device screens

  • Dark-mode — includes color-scheme: light dark meta for clients that support it

  • MSO conditional comments — Microsoft Outlook rendering fixes

  • Multipart/alternative — every email includes a plain-text alternative for better deliverability and accessibility

Internationalization (i18n)

Email subjects, body text, and the brand name are localized via Spring MessageSource:

  • mail_messages.properties (English, default)

  • mail_messages_ru.properties (Russian)

The user’s locale is resolved from user.locale. If unset, English is used as fallback.

The brand name is controlled by the mail.brand message key:

  • English: "Configuration Center"

  • Russian: "Центр Конфигураций"

The MAIL_FROM_NAME environment variable has been removed. The sender display name now comes from the mail.brand message key.

Call-to-action button

The "Sign In" CTA button in emails is optional and controlled by MAIL_LOGIN_URL:

  • When set to a valid http:// or https:// URL, a styled button links to that URL.

  • When blank or non-HTTP, the button is replaced by a generic text hint ("Please sign in via your organization’s portal").

Security

  • All user inputs and MessageSource values are HTML-escaped before insertion into templates.

  • MAIL_LOGIN_URL is validated at startup; non-HTTP/HTTPS values are ignored with a warning log.

See Environment variables for MAIL_* inputs and profile-specific defaults.

Audit retention

Audit events are automatically cleaned up by AuditRetentionService, which runs daily at 03:00.

  • Default retention: 30 days

  • Configurable via AUDIT_RETENTION_DAYS (min 3, max 90, or 0 to disable)

See Auditing — Audit retention for full details.

See Environment variables for AUDIT_RETENTION_DAYS and AUDIT_REDACTION_FIELDS.

Actuator exposure (security note)

src/main/resources/application.yml exposes health, info, metrics, and prometheus actuator endpoints (management.endpoints.web.exposure.include=health,info,metrics,prometheus) and permits them without auth (SecurityConfig). In production, restrict actuator exposure further if needed via:

  • network policy / ingress rules, and/or

  • tightening management.endpoints.web.exposure.include and security rules.

Bootstrap admin provisioning

Configured via:

  • ft-configs.bootstrap.admin.username

  • ft-configs.bootstrap.admin.password

  • ft-configs.bootstrap.admin.email (optional)

  • ft-configs.bootstrap.admin.locale (optional)

See Environment variables for FT_CONFIGS_BOOTSTRAP_ADMIN_* defaults and examples.

Environment variables

Do not commit secrets (*_PASSWORD, JWT_SECRET) into Git. Use .env locally, and use Secret managers (Kubernetes Secrets, Vault, etc.) in shared environments.

HZ_MEMBERS must be reachable from inside the container/pod (Docker and Kubernetes networking apply).

Mail

Variable Required Default Description

MAIL_MODE

No

AUTO

Email delivery mode (case-insensitive; blank or unknown falls back to AUTO with a warning log). The supported values are AUTO and OFFLINE. AUTO infers the mode from SMTP config: it is treated as OFFLINE when MAIL_HOST, MAIL_USERNAME, or MAIL_PASSWORD are not all set (non-blank); when they are all set it attempts email, but if the SMTP server is unreachable at runtime it degrades to offline behaviour. OFFLINE never sends email. In offline mode (configured or degraded at runtime), create-user and reset-password return the temporary password in the API response (passwordDelivery=RETURNED) instead of emailing it, and user-deletion requests skip OTP (returning otpRequired=false); the account is deleted in the confirm step, called without an OTP.
