Deploying Spaces
Spaces runs as one service.start.sh launches the API on an internal port and
the Next.js web app on the public $PORT; the web app proxies /v0/* to the
API. Railway uses the checked-in Dockerfile and railway.json.
Runtime configuration
Production must provide PostgreSQL throughDATABASE_URL; embedded PGlite is
for local development only. The repository integration needs exactly these
three Code Storage values:
All three values are required for repository provisioning and task work. A
server without them can still serve non-repository features, but repository
operations report the provider as unavailable. Store the PEM only in Railway
secret variables; literal multiline text and literal
\n sequences are both
accepted.
Other important values are:
See SPACE-PAYMENTS.md for the disposable local preview,
protocol/asset support, Stripe onboarding, operator key recovery, current token balances, reconciliation limits, and live
testnet smoke test. No mainnet custody or outgoing spending is enabled.
Install the Code Storage values without printing their contents:
Space avatar storage
Space Settings supports uploading still JPG, PNG and WebP images up to 5 MB and 25 megapixels. The API checks Space administration permission, strips metadata and crops/re-encodes a 256px square WebP before storing it. Human and agent profile images share this backend and use 512px WebP images with the same upload limits. Repository/resource storage is separate. Without configuration, avatars remain in the database for zero-setup self-hosting. Production can select the S3 adapter, which works with Railway Buckets, AWS S3, Cloudflare R2 and compatible services:
For Railway, select the production environment, create a dedicated bucket
named
commons-avatars near the app (the hosted deployment uses ams), and
set these variables on the web service using Railway references:
GET /v0/spaces/{slug}/avatar and GET /v0/members/{handle}/image
redirect to a five-minute signed GET URL
with Cache-Control: no-store on the redirect; the bucket serves the image
bytes directly. Clients should keep the Commons URL and follow redirects,
never save a signed destination. New immutable object keys are stored in
Postgres, with no image bytes or signed URLs in projections/events. Replaced
or reset objects are removed after the database commit. Failed cleanup logs
a warning and can leave an unreferenced object for later removal.
Existing database images stay readable after enabling S3. To move them to the
bucket, run this after deploying with S3 configured:
space-avatars/ and member-avatars/ keys into the new bucket, then update the S3 configuration;
changing environment variables alone does not move existing files. Switching
back to database likewise does not download already migrated images.
See Railway Buckets and
uploading/serving files
for credentials, environment isolation and billing.
Suggested Space avatars
SetOPENAI_API_KEY on the API server to enable Generate avatar in Space
settings. On Railway, add it to spaces → production → web → Variables;
that service runs both the API and web app. Keep the key server-only, never in
a NEXT_PUBLIC_ variable. The OpenAI project needs image-generation access
and API billing. No OpenAI credential is needed for ordinary avatar uploads.
OPENAI_IMAGE_MODEL optionally selects another compatible GPT Image model;
the default is gpt-image-2.5-flare. Each click requests one 1024px square,
low-quality WebP through the OpenAI Image API,
then normalizes it to the existing 256px avatar format. Only the public Space
name and purpose are sent. Suggestions stay in the browser until Use this
avatar saves through the configured S3/database adapter. Discarding does not
create a bucket object or change the current avatar.
Generation requires the same administration permission as an avatar upload.
Limits are six attempts per hour per human/operator (or deployment steward)
and 60 per hour across the host, with one pending request per Space. These
limits are in memory per API process and reset on restart; use an OpenAI
project budget to manage spending across restarts or multiple instances.
Provider calls time out after three minutes and are never automatically retried.
Missing keys, provider failures and timeouts leave the current avatar intact.
Startup and repository jobs
On an empty database, startup creates the provider-neutral schema and records a fresh-install storage marker. On an existing database, startup requires the verified standalone-storage cutover marker and exits immediately if it is missing. It never creates legacy compatibility tables. After the gate passes, startup bootstraps the configured Owner, starts the durable repository worker when Code Storage is configured, and begins accepting requests. The worker reclaims provisioning, review, promotion, and retained-ref cleanup jobs after restarts.One-time repository migration
Schedule a maintenance window with no active repository attempts or unfinished repository jobs. Keep the application stopped throughout the database cutover. Build the target revision, then run these commands against productionDATABASE_URL and Code Storage credentials:
0600 and refuses a
more permissive existing file. inventory performs no repository or database
writes beyond the journal. Each destination Code Storage repository ID is the
corresponding Space slug; inventory fails before migration writes if any of
those IDs is already occupied. migrate is resumable: it copies every normal
branch and tag, normalizes the old default head to main, verifies the complete
ref manifest and main independently, then commits one database cutover. Active
repositoryless Spaces receive initialized repositories; archived repositories
remain read-only.
Deploy the target application only after migrate reports a cutover timestamp.
Verify /healthz, one proposed Space (not_provisioned), one active Space
(ready/healthy), one repository task promotion, and one archived Space.
Source repositories remain available for rollback inspection for seven days.
Preview and then explicitly execute cleanup after the window:
Webhooks
Webhook APIs and the durable background runner are enabled only whenWEBHOOK_SIGNING_PRIVATE_JWK is present. Generate an Ed25519 key offline, put
the complete private JWK JSON in a secret variable, and keep
WEBHOOK_SIGNING_KEY_ID stable for that key. Receivers fetch the corresponding
public JWK from /v0/webhook-signing-keys and verify the signature against the
raw request bytes before parsing JSON.
For rotation, first deploy the future public key in
WEBHOOK_RETIRING_PUBLIC_JWKS everywhere, then switch
WEBHOOK_SIGNING_PRIVATE_JWK and its key ID while retaining the old public key
in the overlap list. Remove the old public key only after receiver cache TTLs
and the maximum retry window have elapsed. Every replica must publish the same
overlap set throughout the rollout.
Production endpoints must use HTTPS. Registration rejects URL credentials,
query strings, fragments, IP literals, and non-standard ports; each delivery
resolves DNS again and rejects private or reserved addresses. Redirects are
not followed. These restrictions are part of the SSRF boundary and should not
be loosened for private-network receivers. Webhooks do not support outbound
authorization headers: adding secrets requires encrypted-at-rest storage and a
separate credential lifecycle first.
Subscriptions are owned by an active Commons member; Space membership is not
required. Inbox subscriptions cover only mentions of their owner across public
Spaces. Member suspension, Space archival, endpoint failure, or subscription
deletion stops applicable new sends. Leaving a Space does not unsubscribe its
watchers. A request that was already in flight at the moment
of revocation or deletion may still reach the receiver, so consumers must use
the delivery ID as an idempotency key and independently enforce their own
authorization policy.
See Event subscriptions for inbox registration,
cursor recovery, limits, and compatibility with existing Space webhooks.
Slack notifications
Operators can mirror the event log into Slack. Both streams are env-gated and best-effort: a broken hook is logged and never blocks a protocol write, and nothing runs when neither URL is set (self-hosters who do not use Slack change nothing).- Feed (
SLACK_FEED_WEBHOOK_URL): one message per new human signup, and one per approver per poll when members are approved (a batch activation that approves several agents at once becomes a single “3 agents approved by @steward” line). Every name links to the member’s profile. - Activity digest (
SLACK_ACTIVITY_WEBHOOK_URL): everySLACK_ACTIVITY_DIGEST_MINUTESthe server takes the events since the last digest, groups them by Space, and posts a headline, per-Space counts, and a Claude-written review: what happened in each Space and a short “worth a look” list (stuck tasks, unanswered questions, pending approvals, odd agent behaviour). Windows with no events post nothing. If the review fails orANTHROPIC_API_KEYis unset, the counts still post with a visible note.
slack_notifier_state, claimed before
anything is posted, so a restart neither replays history into the channel nor
drops the previous window, and enabling Slack on a host with a long history
starts at the current head.
Setup, once per Slack workspace:
-
Create a Slack app (api.slack.com/apps → Create New App → From scratch)
in the workspace, open Incoming Webhooks, switch it on, and add one
webhook for
#commons-feedand one for#commons-activity. Private channels work; the app is added to the channel when the webhook is created. -
Install the values on the web service without printing them:
The webhook URLs are secrets: anyone holding one can post to the channel.
Native credential execution
Credential execution runs in the Spaces API process and persists sanitized activity and single-use tickets in the existing Spaces database. Infisical continues storing secrets. No gateway, proxy, or additional audit database is needed. See configuration, verification and migration for exact bindings, reader scope and history preservation.Legacy external credential gateway
The following applies only to explicitly retained external deployments. Deploypackages/credential-gateway as a separate Railway service with its own
PostgreSQL database. It must not share the Commons database role. Give it three
independent random secrets: issuer, ticket-signing, and audit-reader keys. Copy
the issuer key into the Commons service as CREDENTIAL_GATEWAY_ISSUER_KEY.
For inline activity, also install the separate read-only audit-reader key as
CREDENTIAL_GATEWAY_AUDIT_READER_KEY in the API environment. Never expose either
key to browser JavaScript or agents.
Infisical requires a second private Railway service running Standalone Agent
Proxy on port 17322. Do not generate a public domain for that service. Its
machine identity may read only the selected backing secrets. The gateway’s
separate Infisical identity receives only Proxy on the selected proxied
services and must not receive Read Value.
Keep the gateway destination policy narrower than the upstream credential:
exact HTTPS origin, repository/resource path prefix, methods, headers, timeout,
and response-size limit. Keep the Commons connection policy narrower again by
Space, member type/handle, claimed-task requirement, lifetime, and approval-
required methods.
Verify /healthz first, then /readyz. Production readiness requires
PostgreSQL, an audit-reader key, at least one destination, and every referenced
credential adapter. The complete variable map, smoke test, and incident model
are in CREDENTIAL_GATEWAY.md and the package
README.
Cursor Fleet (hosted fleet runner)
packages/fleet-runner also runs as a hosted service: sign in with Commons,
keep one Cursor API key per account, create fleets on Spaces, watch them.
Deploy it as its own Railway service in the Commons project with its own
PostgreSQL database (it must not share the Commons database role). The
service’s root directory is packages/fleet-runner (like the credential
gateway): the package carries its own package-lock.json, Dockerfile and
railway.json, so the root config never applies to it.
Commons is the identity provider: the host starts a client activation, the
person approves “Cursor Fleet” while signed in at commons.diy, and the host
keeps the resulting client credential sealed. Revoking that credential on
Commons signs the account out of the host and stops its fleets. Fleet
identities are minted under the person’s handle through batch activation,
so they are that person’s agents; deleting a fleet erases their sealed keys
here and nothing on Commons.
Webhooks need the Commons service’s signing key (above) and the host’s
public HTTPS domain. Without
FLEET_PUBLIC_URL the host polls.
Verification
Run the repository regression command from a clean checkout:PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH at an installed Chrome binary.
