Configuration Reference

There are two layers of configuration:

1. Application config (vibed.yaml) — runtime settings for the vibed server. In Kubernetes this is rendered into a ConfigMap by the Helm chart and mounted at /etc/vibed/vibed.yaml.
2. Helm values — cluster topology: namespaces, RuntimeClass, NetworkPolicy, the controller/router/caddy components, and the warm pools.

You normally set everything through Helm values; the chart renders the app config for you.

Config is loaded from a file, then VIBED_-prefixed environment variables override individual keys, then the result is validated. A missing config file is not an error — the server starts on defaults. Every field maps to a key defined in internal/config/config.go; the tables below are grouped by top-level section in that struct.

served vs s3

served keeps the source tarball on vibeD's PVC and serves it over the in-cluster Service URL — dev only. Once a restrictive sandbox NetworkPolicy is in place (production), sandboxes have no cluster DNS or cluster-internal egress, so the agent can only pull from a pre-signed s3 URL. Use s3 (S3 or MinIO) in production.

organization

Key	Type	Default	Description
name	string	""	Organization display name, surfaced in the dashboard.

server

Key	Type	Default	Description
transport	string	stdio	stdio, http, or both. Validated — any other value fails startup.
httpAddr	string	:8080	Listen address for the HTTP transport (/v1 API, dashboard, streamable MCP).
baseURL	string	""	Public-facing base URL used to generate share links, e.g. http://localhost:8080.
logFormat	string	text	text or json.
logLevel	string	info	debug, info, warn, or error.
rateLimit.enabled	bool	false	Enable per-client HTTP rate limiting. Covers /api, /mcp, and /v1 (including the deploy path). Off on a network transport logs a startup warning.
rateLimit.requestsPerSecond	float	10	Steady-state rate per client for reads.
rateLimit.burst	int	20	Max burst size per client for reads.
rateLimit.writeRequestsPerSecond	float	1	Stricter steady-state rate for mutating verbs (deploy/create/update/delete), so one user can't flood the expensive deploy path. <=0 → safe default.
rateLimit.writeBurst	int	5	Max burst for mutating verbs. <=0 → safe default.

auth

Governs authentication and TLS termination. When enabled is false the API is open (every request is treated as admin) — enable it before exposing vibeD. To guard against that being exposed by accident, vibeD refuses to start with auth disabled on a non-loopback bind unless devInsecure: true is set. See Authentication for a full walkthrough.

Key	Type	Default	Description
enabled	bool	false	Turn authentication on.
devInsecure	bool	false	Acknowledge running with auth disabled on a non-loopback bind. Required to start in that config (otherwise vibeD refuses); intended for local dev or a network-isolated in-cluster listener. The Helm chart's no-auth path sets it automatically.
mode	string	""	apikey, oauth, or oidc. Out-of-tree providers may register additional modes.
apiKeys	list	[]	Configured API keys (see below). At least one is required when mode is apikey/oauth/empty.
oidc	object	—	OIDC settings (see below).
tls	object	—	TLS termination (see below).
options	map[string]string	{}	Generic bag read by out-of-tree auth providers; core modes ignore it, so a new mode needs no schema change.

auth.apiKeys[]

Key	Type	Default	Description
key	string	—	Token value, or env:VAR_NAME to read it from the environment.
name	string	—	Human-readable name; used as the caller's UserID.
scopes	list	[]	Allowed scopes; empty means all.
role	string	user	admin or user.
department	string	""	Auto-assign the user to this department on first use.
storage	object	—	Optional per-user storage override (github or gitlab, see Storage).

auth.oidc

Key	Type	Default	Description
issuer	string	""	OIDC issuer URL. Required when mode is oidc.
audience	string	""	Expected aud claim. Required when mode is oidc (blocks cross-app token reuse).
usernameClaim	string	preferred_username	JWT claim for the username.
emailClaim	string	email	JWT claim for the email.
roleClaim	string	realm_access.roles	JWT claim path for roles.
adminRole	string	vibed-admin	Role value that maps to a vibeD admin.
departmentClaim	string	""	JWT claim carrying the department name.
scopes	list	["openid","profile"]	Scopes to advertise.

auth.tls

Key	Type	Default	Description
enabled	bool	false	Terminate TLS in vibed.
certFile	string	""	Path to the TLS certificate.
keyFile	string	""	Path to the TLS private key.
autoTLS	bool	false	Generate a self-signed cert for dev. When enabled, either certFile+keyFile or autoTLS is required.

deployment

Key	Type	Default	Description
preferredTarget	string	auto	auto or kubernetes.
namespace	string	default	Default working namespace for the control plane.
appsNamespace	string	vibed-apps	Namespace where /v1 creates VibedApp CRs. Must match where the warm pools live — agent-sandbox requires a SandboxClaim co-located with its SandboxTemplate.
readyTimeout	duration	10m	How long deployers wait for a workload to become Ready before failing the deploy.

storage

The file-tree artifact store used by the legacy MCP build path. Distinct from storage.tarball, which is the source-blob store for the /v1/deploy path. See Storage.

Key	Type	Default	Description
backend	string	local	local, github, or gitlab. Validated at startup.
local	object	—	basePath (default /data/vibed/artifacts).
github	object	—	owner, repo, branch (default main), tokenFile. owner and repo are required when backend is github.
gitlab	object	—	url (default https://gitlab.com), projectID, branch (default main), token. projectID is required when backend is gitlab.
tarball	object	—	Source-blob store for /v1/deploy (see below).

Tokens in github.tokenFile / gitlab.token support env:VAR and file:PATH indirection.

storage.tarball

Selects how /v1/deploy persists the uploaded source tarball so vibed-agent can pull it.

Key	Type	Default	Description
backend	string	served	served (no extra infra) or s3.
served	object	—	basePath (default /data/vibed/sources; should be a PVC), publicBaseURL (in-cluster base the agent dials; the store appends /internal/sources/<id>.tar.gz).
s3	object	—	endpoint (empty for AWS, set for MinIO), bucket, region, accessKey, secretKey, presignTTL (GET URL validity, default 15m).

registry

Optional OCI image registry used by paths that reference images.

Key	Type	Default	Description
enabled	bool	false	Enable registry integration. When true, url is required.
url	string	""	Registry base URL.
insecure	bool	false	Use HTTP instead of HTTPS. See Registry.

store

The state store for control-plane objects (the control plane is stateless; all durable state lives here).

Key	Type	Default	Description
backend	string	sqlite	sqlite (default, recommended — scales per-row), memory, or configmap. Validated at startup.
sqlite	object	—	path (default /data/vibed.db). Required when backend is sqlite.
configmap	object	—	name (default vibed-artifacts), namespace (default vibed-system). Small/dev deployments only — all artifacts share one ConfigMap, bounded by etcd's ~1MB object ceiling; use sqlite at scale.
options	map[string]string	{}	Passed verbatim to the backend factory. Core backends ignore it; an out-of-tree backend reads its own settings (DSN, pool size, …) from here, so adding a backend needs no schema change. See Store backends.

kubernetes

Key	Type	Default	Description
kubeconfig	string	""	Path to a kubeconfig. Empty uses in-cluster config; the KUBECONFIG env var fills this when set and the key is empty.
context	string	""	Kubeconfig context to select.

limits

Guards on MCP tool inputs and log streaming.

Key	Type	Default	Description
maxTotalFileSize	int	52428800	Max total source size per deploy/update, in bytes (50 MiB).
maxFileCount	int	500	Max number of files per deploy/update.
maxLogLines	int	10000	Max log lines returned per request.
maxConcurrentLogStreamsPerUser	int	10	Max simultaneous /v1/logs SSE streams per authenticated user. <=0 falls back to a safe default (not unlimited).
maxConcurrentLogStreamsGlobal	int	100	Max simultaneous /v1/logs SSE streams across all users, so many users can't collectively exhaust controller memory. <=0 → safe default.

quotas

Caps how many concurrent apps an owner or department may hold. Disabled by default; a new deploy is hard-gated when it would exceed either ceiling. Counts are over live VibedApps (by the vibed.dev/owner and vibed.dev/department labels); redeploys of an existing app do not count. See Quotas.

Key	Type	Default	Description
enabled	bool	false	Enforce quotas.
maxAppsPerOwner	int	0	Per-user ceiling. 0 = unlimited.
maxAppsPerDepartment	int	0	Per-department aggregate ceiling. 0 = unlimited.
perDepartment	map[string]int	{}	Override the department ceiling by department name.

audit

Key	Type	Default	Description
failClosed	bool	false	When true, a mutating action (deploy/delete/rollback/suspend) whose audit write cannot be persisted is rejected — preferring availability loss over an untraceable change. The default fails open so dev clusters and the default install don't block deploys; production values flip this to true. See Audit log.

gc

The resource garbage collector, which reaps orphaned resources.

Key	Type	Default	Description
enabled	bool	true	Enable garbage collection.
interval	duration	1h	GC cycle interval. Must be a valid Go duration when enabled.
maxAge	duration	24h	Age threshold for orphaned resources. Must be a valid duration.
dryRun	bool	false	Log candidates without deleting.

tracing

OpenTelemetry distributed tracing.

Key	Type	Default	Description
enabled	bool	false	Enable tracing.
endpoint	string	""	OTLP gRPC endpoint (e.g. http://jaeger:4317). Empty exports to stdout.
sampleRate	float	1.0	Sampling rate, 0.0–1.0.

See deploy/helm/vibed/values.yaml for the fully-documented defaults and values-kind.yaml for the dev overlay. The controller takes flags (--vibed-domain, --app-url-scheme, --app-url-port, --pool-namespace) which the chart wires from the values above.

Extending the config

Several sections carry an options map (or an equivalent seam) so an out-of-tree Go module can plug in a provider without changing this schema:

• auth.options / auth.mode — register a custom authentication mode. See Auth providers.
• store.options / store.backend — register a custom state-store backend that reads its own DSN and tuning from options. See Store backends.

Feature availability is governed by an editions/feature-flag seam whose default enables all features; integrators building their own module can supply a different resolver. See Secrets and features.
