Summary by CodeRabbit

  • New Features

    • Database connection details show external reachability and warnings; gateway connections can use valid host certificates.
    • Project creation supports archive uploads as part of deployment setup.
    • SSH deployments can generate build configuration remotely, and cancelling a build attempts to stop its remote process.
  • Bug Fixes

    • Scaling settings reject invalid values with field-specific errors.
    • Failover checks target availability and cleans up containers on the previous server.
    • SSH-key forms show submission errors and identify duplicate keys; LLM settings prompt for required API keys.
    • Runtime logs and server connection details are more reliable and informative.
  • Documentation

    • Updated guidance for database access, system configuration, and installation.

…ontainers

Abort failover when the chosen target does not answer its SSH port,
refuse automatic failovers within FAILOVER_MIN_INTERVAL_MS (default 10m),
allow disabling the monitor with FAILOVER_DISABLED, and remove the previous
deployment's containers from the old server behind a 30s cap so a dead
host cannot hang the failover.
Remote builds cloned the repo and ran `railpack build .` without ever
consulting the project's sourceDir or projectType, so any project whose
code lives in a subfolder failed with "Railpack could not determine how to
build the app" while the same project deployed fine locally.

Send the local railpack-config-utils.ts source to the target host, write it
into the clone through a quoted heredoc, and run it there with bun, which is
installed unzip-free via python3 when the host has neither bun nor unzip.
Remote failures now read stdout before stderr, so failureReason no longer
reports git's "Cloning into '.'..." instead of the real error.
…eployment's server

ingressSite (the route writer for cross-server projects behind the local
ingress) never emitted CADDY_ACCESS_LOG_BLOCK, so project requests were
never access-logged and request-logs/metrics stayed empty.

Runtime logs ran 'docker logs' against the local node for every
deployment (the SSE stream used a raw spawn, bypassing ssh targeting),
returning [] for anything on a remote server; both handlers now resolve
the deployment's server behind orchestrator/runtime-logs.ts.
…database hosts

Close out the open rows from artifacts/verify-dequel/BUGS.md (005-018,
027, 028, 030-033, 039, 040), live-verified on the primary host.

BUG-027: cancelling a deployment now kills the build's whole process
group (detached local spawns with pgid tracking, DEQUEL_PGID echoed by
the remote script and parsed on abort), and the cancel handler reports
the abort instead of a generic failure.

BUG-039: pam-auth mounts host /etc as a directory and copies
passwd/shadow/group into the container in place every 2s, so
useradd/chpasswd/usermod become visible to PAM immediately — file binds
froze the mount-time inode so logins kept failing until a restart.

BUG-040: Caddy now provisions real Let's Encrypt certificates for db-*
hostnames (site route files database-<host>.caddy written on create,
patch, and delete trigger auto-HTTPS), and the gateway serves those
certs from the shared caddy-data volume (mtime-cached, SAN and expiry
checked, self-signed fallback kept). Live-verified: openssl
-verify_return_error returns 0 for all three public databases and the
node pg driver's verify-full semantics now connect out of the box.

BUG-016: the credentials endpoint probes external reachability and
returns a warning the dashboard surfaces when the endpoint is down.

Also extract authMiddleware into its own module, add lazy repo imports
and orchestrator mocks so bun test runs green again (440 pass, 1
pre-existing DiagRunMachine failure), and correct the database TLS docs
note to describe the new certificate path.
hosts for connections

Wire Caddy certificate detection into connection
strings and resolve direct
database endpoints from their assigned server.
Also begins refactoring
Railpack process cancellation.

Walkthrough

The pull request updates database gateway access, deployment execution and failover, project cleanup, API authentication and validation, server preparation, and web interfaces. It also changes runtime configuration, encryption-key handling, and related documentation and tests.

Changes

Database gateway access

Layer / File(s) Summary
Gateway routes and connection checks
apps/api/src/api/databases/index.ts, apps/api/src/utils/db-caddy-route.ts, apps/api/src/utils/tcp-probe.ts
Database changes synchronize gateway routes. Credential responses probe external endpoints and report reachability, warnings, and certificate-dependent connection strings.
Caddy certificate loading and gateway TLS
apps/api/src/tunnels/cert-store.ts, apps/api/src/tunnels/gateway.ts, docker-compose.yml
The gateway can load a matching Caddy certificate for an SNI hostname. Compose mounts Caddy data for the API and gateway.
Database credential display and documentation
apps/web/src/api/databases.ts, apps/web/src/components/databases/*, apps/docs/src/content/docs/databases.md
The web interface displays credential warnings. Documentation describes gateway access, certificate settings, and MySQL direct-port access.

Deployment execution and runtime logs

Layer / File(s) Summary
Remote Railpack configuration
apps/api/src/executors/ssh-build-script.ts, apps/api/src/executors/__tests__/dispatch.test.ts
Remote build scripts install Bun when needed and generate railpack.json from project settings and embedded generator code.
Remote build cancellation and errors
apps/api/src/executors/ssh.ts, apps/api/src/utils/ssh.ts, apps/api/src/utils/proc-group.ts, apps/api/src/orchestrator/deployment-errors.ts, apps/api/src/orchestrator/compose.ts, apps/api/src/orchestrator/__tests__/deployment-errors.test.ts
The SSH executor captures remote process-group IDs and handles cancellation. Remote script failures combine standard output and standard error. Compose processes use process-tree termination.
Runtime log retrieval and streaming
apps/api/src/orchestrator/runtime-logs.ts, apps/api/src/api/deployments/index.ts, apps/api/src/orchestrator/__tests__/runtime-logs-*
Runtime-log helpers resolve the deployment server and container. The API uses them for log retrieval and stream arguments.
Compose ingress and process handling
apps/api/src/utils/compose-ingress.ts, apps/api/src/utils/ingress.ts, apps/api/src/utils/__tests__/ingress.test.ts, apps/api/src/orchestrator/compose.ts
Compose ingress skips database service names. Generated ingress sites include access logging. Compose cleanup accepts an optional server and suppresses selected Docker cleanup failures.

Server failover

Layer / File(s) Summary
Failover policy and execution
apps/api/src/orchestrator/failover.ts, apps/api/src/utils/config.ts
Failover checks target reachability, applies an interval to automatic failovers, and attempts cleanup on the prior server. The state reports whether failover is disabled and the configured interval.
Failover behavior tests
apps/api/src/orchestrator/__tests__/failover-*
Tests cover unreachable targets, removal of old containers, interval rejection, and project context in errors.

Project resource cleanup

Layer / File(s) Summary
Cleanup target data and orchestration
apps/api/src/db/repo/projects.ts, apps/api/src/api/projects/index.ts, apps/api/src/orchestrator/project-cleanup.ts, apps/api/src/orchestrator/compose.ts
Project cleanup uses structured deployment and database targets, resolves their servers, and delegates container and Compose cleanup.

Server container preparation

Layer / File(s) Summary
Container detection and startup
apps/api/src/servers/prepare.ts
Server preparation detects and reuses matching Caddy and BuildKit containers. It reports startup failures when neither startup nor reuse succeeds.

ZIP project deployments

Layer / File(s) Summary
Archive validation and project submission
apps/api/src/api/deployments/index.ts, apps/web/src/api/client.ts, apps/web/src/routes/CreateProjectPage.tsx
The API validates archive names and sizes. The web flow creates a deployment with the uploaded archive and displays API status codes in errors.

API authentication

Layer / File(s) Summary
Authentication middleware and permissions
apps/api/src/api/auth-middleware.ts, apps/api/src/api/index.ts, apps/api/src/utils/permissions.ts
The router uses shared middleware for bypass paths, session validation, and method-based API-key permissions.

Scaling policy validation

Layer / File(s) Summary
Policy validation and tests
apps/api/src/api/scaling/index.ts, apps/api/src/scaling/__tests__/engine.test.ts
The route rejects invalid policy fields and replica bounds. Tests cover scale-up and scale-down with a zero CPU threshold.

SSH key management

Layer / File(s) Summary
Fingerprint lookup and duplicate handling
apps/api/src/db/repo/ssh-keys.ts, apps/api/src/api/ssh-keys/index.ts
The repository provides fingerprint calculation and lookup. The API rejects malformed keys and reports duplicate fingerprints.
SSH key form and list
apps/web/src/components/settings/SshKeyPoolSection.tsx
The form displays creation errors and submission state. The key list and deletion confirmation show updated labels.

Web settings and display

Layer / File(s) Summary
Provider model and API-key settings
apps/api/src/fixdiag/provider-models.ts, apps/web/src/components/settings/LlmKeysSection.tsx
Several provider defaults are removed. The settings form prompts for a required API key and disables saving when it is missing.
Server and login labels
apps/web/src/components/settings/ServersSection.tsx, apps/web/src/routes/Login.tsx
Server rows show connection labels for local, agent, and SSH modes. The login mockup displays the current origin when available.

API and encryption configuration

Layer / File(s) Summary
Configuration values and migration
apps/api/src/utils/config-loader.ts, apps/api/src/utils/config.ts, apps/api/src/utils/crypto.ts, apps/api/src/db/migrate.ts, apps/api/src/api/github/index.ts, apps/api/src/index.ts
Configuration fields and sources change. Bootstrap runs encryption-key migration, and GitHub integration seeding from configuration is removed.
Encryption key setup
scripts/dequel, scripts/install.sh
The CLI selects or generates an encryption key, exports it, and writes it to .env when needed. Installer output includes the key in .env.
Server selection and PAM synchronization
apps/api/src/utils/server-default.ts, docker-compose.yml
Server selection dynamically loads repository functions. Compose synchronizes host account files into the PAM container.

Configuration and route documentation

Layer / File(s) Summary
Configuration and route documentation
apps/docs/src/content/docs/system-config.md, apps/docs/src/content/docs/agent-caddy-routes.md, apps/docs/src/content/docs/installation.md, apps/docs/src/content/changelogs/v0.4.0.md
Documentation describes configuration tiers, route paths, installation setup, and changelog entries.

Merge Risk: 🟠 High · up to 7b6e7

Deployments without an explicit encryption key store secrets under a publicly known key, a failed key migration is ignored at startup, and several previously reported deployment, cleanup, and cancellation defects remain open. Resolve these before merging.

apps/web/src/routes/CreateProjectPage.tsx:138-153
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Validation errors do not reset errorStatus consistently, and stale errors persist on field edits.

clearError() runs at the start of handleSubmit, so the status resets on each submit. The error message still stays visible after the user edits a field, until the next submit. The retrieved learning requires clearing the error state when the user edits the relevant fields.

This is a minor UX gap. Clear the error in the field setters, or in an effect that depends on name, repoUrl, and zipFile.

20-28: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

A valid session cookie blocks the API-key path, and an invalid cookie causes a failure even when the Bearer key is valid.

The middleware checks the cookie branch first. If dequel_session is present but expired or invalid, the middleware returns 401 and never evaluates the Authorization header. A client can send both a stale browser cookie and a valid API key, for example a CLI that shares a cookie jar. That client then gets "Invalid session" and no Bearer fallback. The fix: when cookie verification fails, continue to the Bearer check. Return 401 only if neither credential is valid.

Proposed fix
 		if (match) {
 			const { verifyAccessToken } = await import("../utils/auth");
 			const payload = await verifyAccessToken(match[1]);
 			if (payload) return;
-			set.status = 401;
-			return fail("Invalid session");

Fingerprint the value that validation accepts.

If two requests contain the same key and one adds surrounding whitespace, Line 17 accepts both after trimming. This line hashes the original strings, so the duplicate lookup misses the existing key. Normalize the private key once, then use that value for validation, fingerprinting, and createSshKey.

Bound replica counts to the database column range.

Number.isInteger(2147483648) is true, so this validator accepts that value. Both replica bounds use PostgreSQL integer columns. The subsequent insert or update fails instead of returning the intended validation error. Reject values outside the column range. (github.com)

Reject zero replica bounds until scale-to-zero works.

The validator accepts minReplicas: 0 and maxReplicas: 0. The engine counts at least one primary replica. At one replica, scale-down attempts to remove replica-1 rather than the primary container. The configured zero-replica target is never reached. Require at least one replica, or implement scale-to-zero throughout the engine. (github.com)

Allow zero CPU thresholds in the scaling-policy validator.

The scaling engine tests explicitly use cpuThresholdPercent: 0 for valid scale-down and scale-up behavior. The policy type and database schema also impose no positive lower bound. However, PUT /projects/:id/scaling rejects zero before persistence. Accept zero and update both percentage error messages because isPercent is shared by CPU and memory thresholds.

Allow custom providers that do not require an API key.

Line 41 treats every unconfigured custom provider as requiring a key. However, apps/api/src/api/settings/llm.ts:60-109 requires a custom provider’s baseURL, not its API key, and fetchCustomModels accepts an optional key in apps/api/src/fixdiag/provider-models.ts:175-204.

Keep supported models in the fallback catalog.

The model picker uses DEFAULT_PROVIDER_MODELS when cached provider models are empty. fetchProviderModels also returns this catalog when discovery returns no models. Retain the supported entries, including gemini-3.7-flash, which was omitted from the original list.

Restrict reflected CORS origins.

origin: () => true reflects every request origin. credentials: false prevents credentialed CORS access, and the session cookies use HttpOnly and SameSite protections. However, protected routes also accept Authorization: Bearer ... API keys, so any browser context that already holds an API key can call and read those routes from any origin.

The dashboard uses relative /api URLs, so derive an allowlist from the configured dashboard origin or disable CORS for same-origin deployments. Preserve credentials: false; reverting to cors() restores the package default of enabling credentials.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

The credentials endpoint probes the gateway from inside the network, so reachability results can be wrong.

The API container calls probeTcp(gatewayHost, 443). That checks whether the API host can reach port 443. It does not check whether external clients can reach it. Every credentials request also waits for DNS resolution plus a TCP connect timeout of up to 2 s. If the API container cannot reach its own public hostname (hairpin NAT is unavailable), the endpoint returns externalConnectionString: null while the gateway works for external clients. The user then has no connection string to use. Return the connection string in all cases. Use the probe result only to set warning and externalReachable.

Proposed fix
-			const reachable = await probeTcp(gatewayHost, 443);
-			if (reachable) {
-				const hasRealCert = ...
-				return ok({ ... externalConnectionString: buildGatewayConnectionString(...), ... });
-			}
-			return ok({ ... externalConnectionString: null, ... });
+			const reachable = await probeTcp(gatewayHost, 443);
+			const hasRealCert = config.caddyDataDir
+				? (await loadCaddyCert(config.caddyDataDir, gatewayHost)) !== null
+				: false;
+			return ok({
+				...,
+				externalConnectionString: buildGatewayConnectionString(dbRecord, gatewayHost, hasRealCert),
+				externalReachable: reachable,
+				warning: reachable ? null : `Gateway endpoint ${gatewayHost}:443 could not be verified ...`,
+			});

Validate and write replica bounds atomically.

Two concurrent partial PUTs can read the same bounds and each pass this check. For an existing range of 1–5, a request setting minReplicas: 5 and another setting maxReplicas: 2 can then persist 5–2. The repository performs separate reads and updates without an atomic range check. Serialize the updates or check the effective range in the write transaction. (github.com)

Keep each volume name with its server ID.

The new database target records identify the owning server, but databaseVolumeNames remains a separate list. The deletion route therefore runs volume rm against the local Docker daemon. A database volume on a remote server remains after project deletion. Keep volumeName in each target and remove it through that target's server. Project volumes need the same server-aware cleanup. The runtime creates project volumes on the deployment's target server. (raw.githubusercontent.com)

Use exact name matching in find_container and find_running_container.

grep -m1 "$1" treats the name as a regex and matches any part of a container name. The lookup for buildkit therefore also matches names like my-buildkit-cache or buildkit_old. The lookup for dequel-caddy also matches dequel-caddy-old.

Failure path when the running check matches the wrong container:

  1. Assume another container whose name contains buildkit is running.
  2. ensure_container logs "already running" for that container.
  3. remove_stopped at Line 139 then deletes the real stopped buildkit container, because remove_stopped uses exact matching.
  4. Preparation still reports success, but the server no longer has a container named buildkit.

Failure path when the existing-container check matches the wrong container:

  1. At Line 145, docker start "$existing" can start an unrelated stopped container instead of creating the Dequel container.

remove_stopped already uses grep -qxF. Use the same exact, fixed-string matching in both lookups. Reuse of a different container is already handled on purpose by equivalent_running.

These lookups also run docker without $SUDO, while docker start and docker run use it. If the user can run Docker only through sudo, the lookups find nothing. A later name conflict then hits the fatal exit 1 path at Line 169. Consider adding $SUDO to the read-only docker ps and docker inspect calls as well.

Handle signals that were aborted before runRemoteScript starts. addEventListener does not replay an earlier abort. When a caller passes an already-aborted signal, this function starts SSH and can run the entire remote script. Check options.signal.aborted and use the same termination path before writing the script.

Handle stdin errors when abort closes SSH. If cancellation kills SSH while a large script is still being written, child.stdin can emit EPIPE or a write-after-end error. The child’s error listener does not handle errors emitted by its stdin stream. Attach a stdin error listener so one cancelled operation cannot crash the API process. Based on learnings: a spawned child’s stdin requires its own error listener when an early exit can interrupt a write.

- MySQL is the exception: its wire protocol begins with a server greeting before the client sends anything, so there is no hostname for the gateway to route on. Exposed MySQL databases keep the direct port path (`<server-ip>:<random-port>`); open that port in your firewall, or use the dashboard SQL console.
- The gateway terminates TLS with a platform certificate. MongoDB strings skip verification (`tlsAllowInvalidCertificates`). For PostgreSQL, `sslmode=require` skips verification in libpq/psql, but the Node `pg` driver treats it as full verification — there, either append `&uselibpqcompat=true` (Node only; psql rejects that flag) or set `ssl: { rejectUnauthorized: false }` in client code. Redis clients verify certificates by default, so set `rejectUnauthorized: false` in your client configuration.
- The gateway terminates TLS with a Let's Encrypt certificate for the database hostname — Caddy issues it within seconds of enabling Public Access and renews it automatically — so the strings above verify out of the box. In the gaps (right after enabling Public Access, or on a `localhost` setup with no base domain) the gateway falls back to a self-signed certificate: MongoDB strings carry `tlsAllowInvalidCertificates=true` (verification off) until a real certificate exists; for PostgreSQL append `&uselibpqcompat=true` (Node only; psql rejects that flag) or set `ssl: { rejectUnauthorized: false }` in client code; Redis clients verify certificates by default, so set `rejectUnauthorized: false` in your client configuration while the fallback is in effect.

Do not recommend disabling certificate verification for fallback connections.

These instructions disable enforcement of server-certificate validation: MongoDB documents tlsAllowInvalidCertificates=true as disabling validation, and node-postgres maps sslmode=require with uselibpqcompat=true to rejectUnauthorized: false. The Redis instruction also sets that option. A network attacker could then impersonate the database endpoint and capture credentials or traffic. MongoDB warns that this setting can expose clients to processes posing as valid servers. (mongodb.com)

Tell users to wait for a CA-valid certificate or document how to trust the fallback certificate securely. Warn users not to send production credentials or data while verification is disabled.

Partial failure leaves an orphaned project when the ZIP deployment fails.

createDeployment runs after createProject succeeds. The API rejects empty archives and unsupported extensions with status 400. In that case the catch block sets the error state, but the project stays created. The env-var failure path at lines 194-203 deletes the project on failure. This path does not.

The user then sees "Retry Deployment". A retry calls createProject again with the same name. This can create a duplicate project or fail on a name conflict.

Delete the created project when createDeployment fails. Alternatively, validate the archive extension and size on the client before creating the project.

Reject hook creation when no webhook secret is configured.

If the integration has no webhookSecret, the code sends an empty secret to GitHub. GitHub then signs no payloads. The /webhook handler already rejects every delivery when no secret exists. The hook is created but never works.

Return a 400 error with a clear message before creating the hook.

Do not continue startup after an encryption migration failure.

The .catch logs the error and lets the API start. If the migration fails partway, some rows stay under the old key. Later decryption with config.envEncryptionKey then fails or returns wrong data. Let the error propagate so the process stops, or retry the migration and verify its result.

withEnv("DATABASE_URL", "") returns an empty string when the variable is unset. The database client then fails with an unclear connection or parsing error at runtime. Throw a clear error at configuration load, or at first use in getDb.

Do not fall back to a hardcoded default encryption key.

If ENV_ENCRYPTION_KEY is unset, config.envEncryptionKey becomes the public constant "dev-env-key-change-me". The code then encrypts SMTP passwords and other secrets with a key that anyone can read in the repository. These secrets are effectively stored in plaintext.

Fail at startup in production when the variable is missing. Alternatively, generate and persist a random key, as the CLI does. Use the default only in an explicit development mode.

Based on learnings: "Never persist those secrets in plaintext" when no real encryptor is available.

Set ownership for directories created with sudo.

When a non-root developer runs the API, config.workspaceRoot and config.caddyRoutesDir resolve to /app/workspace and /caddy/routes. The API creates deployment directories and Caddy route files under these paths. If sudo mkdir creates the parent directories with non-writable permissions for the developer, those operations can fail.

Review comment at @apps/docs/src/content/docs/installation.md at line 146:
Update the installation instructions around the `sudo mkdir` command to set
`/app/workspace` and `/caddy/routes` ownership to the developer running the
setup, so the API can write deployment directories and Caddy route files there.

Require a deployment-specific encryption key.

When ENV_ENCRYPTION_KEY is unset, both Compose services receive the public value dev-env-key-change-me. The API uses this key to encrypt persisted environment variables and other secrets. Anyone who obtains the encrypted values and their stored IVs and authentication tags can derive the same key and decrypt them.

Fail closed when the variable is missing:

Update the ENV_ENCRYPTION_KEY settings for both Compose services to fail closed

Restrict an existing .env before writing the encryption key.

If .env exists without ENV_ENCRYPTION_KEY and has permissive permissions, this branch appends the secret without changing those permissions. Apply mode 600 before writing to an existing file, as the new-file branch already does.

Update the existing-file branch in the `ENV_ENCRYPTION_KEY` check to set
`$env_file` permissions to mode 600 before appending the key, matching the
new-file branch’s permissions.
