## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Docker image keeps all instance state under `PAPERCLIP_HOME`,
and deployments mount a volume there
> - Before it drops privileges, the entrypoint makes sure that the
`node` user owns the home (#10530)
> - The ownership probe is a first-mismatch `find` over the whole tree.
When ownership is correct, `-quit` never fires, so every boot stats
every file on the volume
> - On homes with many agent worktrees and `node_modules` trees, this
walk takes minutes before Node starts. That is close to common 300s
healthcheck windows
> - This pull request keeps a cheap shallow probe on every boot. It runs
the full-tree probe only once per volume and node UID/GID, and records
the result in a marker file
> - The benefit is that routine boots no longer scale with the file
count, and the original root-owned-volume fix stays in place
## Linked Issues or Issue Description
Refs #10431 (the open follow-up about the remaining cost of the
ownership walk). Related: #10530 (the change that added the full-tree
probe).
**What happened?**
On a hosted multi-instance deployment, we measured the time from
container start to the first app log line. Instances with many files on
the volume (agent worktrees with `node_modules`) took about 190-235s.
Small instances took 5-22s. One 30 GB volume with few files took 24s, so
the cost follows the file count, not the volume size. Almost all of this
time is the `find "$home_dir" \( ! -user node -o ! -group node \) -print
-quit` walk in `scripts/docker-entrypoint.sh`. When ownership is already
correct, `-quit` never fires, so the walk stats every inode on every
boot.
**Expected behavior**
When ownership is already correct, the entrypoint pre-start phase is
short and does not depend on the number of files in `PAPERCLIP_HOME`. A
fresh root-owned volume, a UID/GID remap, and an upgrade from an older
image are still repaired before the privilege drop.
**Steps to reproduce**
1. Run the image with a volume on `/paperclip` that holds a few hundred
thousand files, all owned by `node:node`.
2. Restart the container.
3. Compare the container start time with the first server log line. The
gap grows with the file count, even though no `chown` runs.

**Deployment mode**
Docker production image (any platform that mounts a volume on
`PAPERCLIP_HOME`)
## What Changed
- `scripts/docker-entrypoint.sh`: the ownership probe is now tiered.
- Every boot runs a shallow probe (`find -maxdepth 3`) over the home and
its first three levels. A fresh root-owned mount and a UID/GID remap
both change the owner of the home directory, so this probe catches them.
- The full-tree probe runs only when
`PAPERCLIP_HOME/.paperclip-ownership-verified` is missing or records a
different node UID/GID (format `v1 <uid>:<gid>`). This catches deep
mismatches, including the first boot after an upgrade from an older
image.
- Any mismatch repairs the whole tree with `chown -R node:node`, as
before. After a clean probe or a repair, the entrypoint writes the
marker as the `node` user (through `gosu`), so the marker never trips
the shallow probe. A failed marker write is ignored: the only cost is a
full probe on the next boot. If `find` exits non-zero without a mismatch
(for example, an I/O error), the walk is incomplete, so the entrypoint
does not write the marker and the next boot probes again.
- `scripts/docker-entrypoint.sh`: timestamped log lines at entrypoint
start, around the full probe and the repair (with durations), and right
before the `exec` of the server. You can now measure the pre-start phase
from the container log.
- `server/src/__tests__/docker-entrypoint.test.ts`: the `find` stub now
tells the shallow probe from the full probe. New tests cover each path
(see Verification).
- `doc/DOCKER.md`: documents the marker, how to force a full check, and
the new log lines.
## Verification
- `cd server && npx vitest run src/__tests__/docker-entrypoint.test.ts
src/__tests__/container-init-reaping.test.ts
src/__tests__/docker-build-stamp.test.ts`: 40 passed. New cases:
- correct ownership + current marker → shallow probe only, no full walk,
no `chown`
- current marker + deep-only mismatch → full walk skipped (this is the
documented trade-off)
- no marker (upgrade) → one full walk, no `chown`, marker written as `v1
1000:1000`
- no marker + deep mismatch → full walk finds it, `chown -R`, marker
written
- root-owned top level with a current marker → `chown -R` without a full
walk
- full walk fails without a mismatch → no `chown`, no marker, retry
logged
- marker for another UID/GID → full walk runs again, marker rewritten as
`v1 1001:1001`
- timestamped `starting`, `ownership repair finished in Ns`, and
`starting app as node` lines, in order, before the command runs
- The new tests fail against the old script. The 11 existing tests pass
unchanged.
- `cd server && npx tsc --noEmit`: passes.
- `shellcheck -s sh scripts/docker-entrypoint.sh`: clean. `dash -n`:
syntax OK.
- Manual run with the real `find` (BSD find, script run under `dash`)
against a 200k-file tree. Only `id`/`usermod`/`groupmod`/`chown`/`gosu`
were stubbed, and `node` was mapped to the local user and group:
- boot 1, no marker, one deep group mismatch → full probe, `chown -R`,
marker written
- boot 2, marker present → no full probe, no `chown`
- boot 3, no marker, clean tree → full probe, no `chown`, marker written
- boot 4, marker present, clean → no full probe, no `chown`
- boot 5, top-level group mismatch with marker → `chown -R`
- I did not build the image or measure boot time in a container. Docker
was not available on the machine I used. On a warm local disk the full
walk is sub-second, so the local timings say nothing about cold network
block storage.
## Risks
- Once the marker is current, a mismatch deeper than three levels is not
detected automatically. Examples: files written as root by `docker exec`
or a restore run as root, after the first verified boot. Before this
change, those files were repaired on the next boot. The workaround is in
`doc/DOCKER.md`: delete the marker and restart. A remap, a fresh volume,
and a root-owned top level are still detected on every boot.
- On the first boot after an upgrade, each existing volume pays one full
walk (the same cost as today). Later boots skip it.
- The marker is a new dotfile in `PAPERCLIP_HOME`. Backups and copies
that include the home carry it along. This is safe, because the marker
records the UID/GID that it verified, and a different UID/GID forces a
new full probe.
- The non-root path (restricted PodSecurity, OpenShift) does not change,
apart from two new stdout log lines.
## Model Used
- Claude Opus 5.5 (`claude-opus-5-5`, 1M context) via Claude Code, with
tool use (shell, file editing). Default reasoning mode.

Docker Quickstart
Run Paperclip in Docker without installing Node or pnpm locally.
All commands below assume you are in the project root (the directory containing package.json), not inside docker/.
Building the image
docker build -t paperclip-local .
The Dockerfile installs common agent tools (git, gh, curl, wget, ripgrep, python3) and the Claude, Codex, and OpenCode CLIs.
Build arguments:
| Arg | Default | Purpose |
|---|---|---|
USER_UID |
1000 |
UID for the container node user (match your host UID to avoid permission issues on bind mounts) |
USER_GID |
1000 |
GID for the container node group |
CLI_TOOLS_CACHE_EPOCH |
empty | Refresh the CLI-install layer; CI supplies the current ISO week |
PAPERCLIP_BUILD_VERSION |
empty | Runtime version when Git metadata is unavailable |
PAPERCLIP_BUILD_COMMIT |
empty | Source commit written into the server build stamp and runtime environment |
Changing the build version or commit preserves the CLI-install cache. The tool layer refreshes when its weekly epoch, base image, installation command, or earlier build inputs change. Local builds can set a new epoch explicitly to refresh tools without clearing the entire build cache.
docker build -t paperclip-local \
--build-arg USER_UID=$(id -u) --build-arg USER_GID=$(id -g) .
Standard images and downstream composition
The Docker workflow publishes the standard production target for Linux AMD64
and ARM64. Canonical master pushes also publish
ghcr.io/paperclipai/paperclip:sha-<FULL_SHA> and a GitHub/Sigstore attestation
for its immutable multi-platform digest. Downstream services can compose their
own images from this public base without rebuilding Core.
Stamped standard images include the build-owned remote provider pack at
/opt/paperclip-runner/provider-pack and set
PAPERCLIP_RUNNER_REMOTE_PROVIDER_PACK_PATH to that directory. Downstream
compositions and the explicit cloud target inherit both. The pack is required
on the controller for remote OpenCode and ACPX runs, even when the sandbox has
preinstalled providers; setting the environment variable alone cannot repair an
image that omits the pack. Rebuild and redeploy from a standard image containing
the pack if runs fail with runner_remote_provider_artifact_incompatible.
Local Docker builds must supply a full PAPERCLIP_BUILD_COMMIT to include a
qualified pack. Unstamped builds remain usable for local adapters and skip pack
generation. The pack stays root-owned and readable by remapped runtime UIDs.
The legacy recurring public -cloud publisher is retired. Master pushes,
release tags, and manual Docker dispatches no longer build that variant.
Existing -cloud tags and digests remain in the registry for rollback; their
release-channel aliases no longer advance. This change deletes no images,
cache tags, or migrator artifacts.
The cloud Dockerfile target remains available for explicit
preview builds. Those requests still publish a
full-SHA -cloud tag when needed. They do not advance a release channel or
replace downstream private composition.
A published image alone does not prove source tests or migration compatibility. Downstream deployment tooling must verify source proof, the standard image attestation, the exact-source migrator, and its own composed image before rollout. Resolve immutable digests instead of deploying mutable tags.
One-liner (build + run)
docker build -t paperclip-local . && \
docker run --name paperclip \
-p 3100:3100 \
-e HOST=0.0.0.0 \
-e PAPERCLIP_HOME=/paperclip \
-e BETTER_AUTH_SECRET=$(openssl rand -hex 32) \
-e PAPERCLIP_TOOL_ACTION_SIGNING_SECRET=$(openssl rand -hex 32) \
-v "$(pwd)/data/docker-paperclip:/paperclip" \
paperclip-local
Open: http://localhost:3100
Data persistence:
- Embedded PostgreSQL data
- uploaded assets
- local secrets key
- local agent workspace data
All persisted under your bind mount (./data/docker-paperclip in the example above).
Docker Compose
Quickstart (embedded SQLite)
Single container, no external database. Data persists via a bind mount.
BETTER_AUTH_SECRET=$(openssl rand -hex 32) \
PAPERCLIP_TOOL_ACTION_SIGNING_SECRET=$(openssl rand -hex 32) \
docker compose -f docker/docker-compose.quickstart.yml up --build
Defaults:
- host port:
3100 - persistent data dir:
./data/docker-paperclip
Optional overrides:
PAPERCLIP_PORT=3200 PAPERCLIP_DATA_DIR=../data/pc \
docker compose -f docker/docker-compose.quickstart.yml up --build
Note: PAPERCLIP_DATA_DIR is resolved relative to the compose file (docker/), so ../data/pc maps to data/pc in the project root.
If you change host port or use a non-local domain, set PAPERCLIP_PUBLIC_URL to the external URL you will use in browser/auth flows.
Pass OPENAI_API_KEY and/or ANTHROPIC_API_KEY to enable local adapter runs.
Full stack (with PostgreSQL)
Paperclip server + PostgreSQL 17. The database is health-checked before the server starts.
BETTER_AUTH_SECRET=$(openssl rand -hex 32) \
docker compose -f docker/docker-compose.yml up --build
PostgreSQL data persists in a named Docker volume (pgdata). Paperclip data persists in paperclip-data.
Untrusted PR review
Isolated container for reviewing untrusted pull requests with Codex or Claude, without exposing your host machine. See doc/UNTRUSTED-PR-REVIEW.md for the full workflow.
docker compose -f docker/docker-compose.untrusted-review.yml build
docker compose -f docker/docker-compose.untrusted-review.yml run --rm --service-ports review
Authenticated Compose (Single Public URL)
For authenticated deployments, set one canonical public URL and let Paperclip derive auth/callback defaults:
services:
paperclip:
environment:
PAPERCLIP_DEPLOYMENT_MODE: authenticated
PAPERCLIP_DEPLOYMENT_EXPOSURE: private
PAPERCLIP_PUBLIC_URL: https://desk.koker.net
PAPERCLIP_PUBLIC_URL is used as the primary source for:
- auth public base URL
- Better Auth base URL defaults
- bootstrap invite URL defaults
- hostname allowlist defaults (hostname extracted from URL)
For fresh authenticated/private Docker or appliance-style installs, the first
admin can now be claimed entirely from the browser after sign-in. Open the
Paperclip URL, sign in or create an account, then choose Claim this instance
on the setup screen. This browser claim is disabled for authenticated/public;
public deployments should run the high-entropy CLI invite fallback instead:
pnpm paperclipai auth bootstrap-ceo
Granular overrides remain available if needed (PAPERCLIP_AUTH_PUBLIC_BASE_URL, BETTER_AUTH_URL, BETTER_AUTH_TRUSTED_ORIGINS, PAPERCLIP_ALLOWED_HOSTNAMES).
Set PAPERCLIP_ALLOWED_HOSTNAMES explicitly only when you need additional hostnames beyond the public URL host (for example Tailscale/LAN aliases or multiple private hostnames).
Optional Vercel Connect credentials
Vercel Connect's backend integration is retained for controlled testing and
existing Vercel-backed connections, but its new-connection UI is currently
withheld from Apps → Browse. Setting
PAPERCLIP_VERCEL_CONNECT_ENABLED=true does not expose a customer-facing setup
entry. Native provider setup screens remain unchanged. Vercel-hosted deployments use the
workload OIDC token Vercel injects. Other hosted and self-hosted deployments
can provide PAPERCLIP_VERCEL_CONNECT_ACCESS_TOKEN as a deployment bootstrap
secret only when that token type is accepted by the live Connect API:
services:
paperclip:
environment:
PAPERCLIP_VERCEL_CONNECT_ENABLED: "true"
PAPERCLIP_VERCEL_CONNECT_ACCESS_TOKEN: ${PAPERCLIP_VERCEL_CONNECT_ACCESS_TOKEN}
Do not save that access token in a company secret or connection config. It is instance bootstrap authority for the operator-selected Vercel account. A token's long expiry and broad Vercel scope do not prove Connect compatibility; validate it with connector metadata before rollout. Workload OIDC takes precedence when both authorities are present. Turning the feature flag off hides new Vercel-backed setup; existing connections keep resolving while workload OIDC or the bootstrap token remains available. Missing or invalid authority fails closed. See the Vercel Connect operator guide.
Claude + Codex Local Adapters in Docker
The image pre-installs:
claude(Anthropic Claude Code CLI)codex(OpenAI Codex CLI)python3(used to run local subscription sign-in in a pseudo-terminal)
Start the container, then open Apps → Connections to connect a Claude or Codex subscription in your browser. You can also enter a provider API key there. You do not run a shell command or configure a CLI home.
docker run --name paperclip \
-p 3100:3100 \
-e HOST=0.0.0.0 \
-e PAPERCLIP_HOME=/paperclip \
-v "$(pwd)/data/docker-paperclip:/paperclip" \
paperclip-local
Notes:
- The image provides the CLI and Python prerequisites for local subscription sign-in.
- Adapter environment checks in Paperclip surface missing authentication or CLI prerequisites.
Podman Quadlet (systemd)
The docker/quadlet/ directory contains unit files to run Paperclip + PostgreSQL as systemd services via Podman Quadlet.
| File | Purpose |
|---|---|
docker/quadlet/paperclip.pod |
Pod definition — groups containers into a shared network namespace |
docker/quadlet/paperclip.container |
Paperclip server — joins the pod, connects to Postgres at 127.0.0.1 |
docker/quadlet/paperclip-db.container |
PostgreSQL 17 — joins the pod, health-checked |
Setup
-
Build the image (see above).
-
Copy quadlet files to your systemd directory:
# Rootless (recommended) cp docker/quadlet/*.pod docker/quadlet/*.container \ ~/.config/containers/systemd/ # Or rootful sudo cp docker/quadlet/*.pod docker/quadlet/*.container \ /etc/containers/systemd/ -
Create a secrets env file (keep out of version control):
cat > ~/.config/containers/systemd/paperclip.env <<EOL BETTER_AUTH_SECRET=$(openssl rand -hex 32) PAPERCLIP_TOOL_ACTION_SIGNING_SECRET=$(openssl rand -hex 32) POSTGRES_USER=paperclip POSTGRES_PASSWORD=paperclip POSTGRES_DB=paperclip DATABASE_URL=postgres://paperclip:paperclip@127.0.0.1:5432/paperclip # OPENAI_API_KEY=sk-... # ANTHROPIC_API_KEY=sk-... EOL -
Create the data directory and start:
mkdir -p ~/.local/share/paperclip systemctl --user daemon-reload systemctl --user start paperclip-pod
Quadlet management
journalctl --user -u paperclip -f # App logs
journalctl --user -u paperclip-db -f # DB logs
systemctl --user status paperclip-pod # Pod status
systemctl --user restart paperclip-pod # Restart all
systemctl --user stop paperclip-pod # Stop all
Quadlet notes
- First boot: Unlike Docker Compose's
condition: service_healthy, Quadlet'sAfter=only waits for the DB unit to start, not for PostgreSQL to be ready. On a cold first boot you may see one or two restart attempts injournalctl --user -u paperclipwhile PostgreSQL initialises — this is expected and resolves automatically viaRestart=on-failure. - Containers in a pod share
localhost, so Paperclip reaches Postgres at127.0.0.1:5432. - PostgreSQL data persists in the
paperclip-pgdatanamed volume. - Paperclip data persists at
~/.local/share/paperclip. - For rootful quadlet deployment, remove
%hprefixes and use absolute paths.
Onboard Smoke Test (Ubuntu + npm only)
Use this when you want to mimic a fresh machine that only has Ubuntu + npm and verify:
npx paperclipai onboard --yescompletes- the server binds to
0.0.0.0:3100so host access works - onboard/run banners and startup logs are visible in your terminal
Build + run:
./scripts/docker-onboard-smoke.sh
Open: http://localhost:3131 (default smoke host port)
Useful overrides:
HOST_PORT=3200 PAPERCLIPAI_VERSION=latest ./scripts/docker-onboard-smoke.sh
PAPERCLIP_DEPLOYMENT_MODE=authenticated PAPERCLIP_DEPLOYMENT_EXPOSURE=private ./scripts/docker-onboard-smoke.sh
SMOKE_DETACH=true SMOKE_METADATA_FILE=/tmp/paperclip-smoke.env PAPERCLIPAI_VERSION=latest ./scripts/docker-onboard-smoke.sh
Notes:
- Persistent data is mounted at
./data/docker-onboard-smokeby default. - Container runtime user id defaults to your local
id -uso the mounted data dir stays writable while avoiding root runtime. - Smoke script defaults to
authenticated/privatemode soHOST=0.0.0.0can be exposed to the host. - Smoke script defaults host port to
3131to avoid conflicts with local Paperclip on3100. - Smoke script also defaults
PAPERCLIP_PUBLIC_URLtohttp://localhost:<HOST_PORT>so bootstrap invite URLs and auth callbacks use the reachable host port instead of the container's internal3100. - In authenticated mode, the smoke script defaults
SMOKE_AUTO_BOOTSTRAP=trueand drives the real bootstrap path automatically: it signs up a real user, runspaperclipai auth bootstrap-ceoinside the container to mint a real bootstrap invite, accepts that invite over HTTP, and verifies board session access. - Run the script in the foreground to watch the onboarding flow; stop with
Ctrl+Cafter validation. - Set
SMOKE_DETACH=trueto leave the container running for automation and optionally write shell-ready metadata toSMOKE_METADATA_FILE. - Set
SMOKE_CONTAINER_NAMEto fix the container's name up front. Automation that has to collect diagnostics when the script fails needs a name it already knows, rather than one it can only read back out of a successful run. Defaults to the image name. - The container's logs are dumped to
SMOKE_LOG_FILE(default$TMPDIR/<container name>.log) before the script tears the container down, so a run that never became ready still leaves its logs behind. - The image definition is in
docker/Dockerfile.onboard-smoke.
General Notes
- The
docker-entrypoint.shadjusts the containernodeuser UID/GID at startup to match the values passed viaUSER_UID/USER_GID, avoiding permission issues on bind-mounted volumes. - Before it drops privileges, the entrypoint makes sure
PAPERCLIP_HOMEis owned by thenodeuser. Each boot checks only the home directory and its first three levels. The first boot (and any boot after a UID/GID change) also checks the full tree, and then writesPAPERCLIP_HOME/.paperclip-ownership-verified. While that marker is current, later boots skip the full-tree walk, which can take minutes on homes with many files. A mismatch triggers a recursivechown. If files deep in the tree get the wrong owner (for example, after a restore as root), delete the marker and restart to force a full check. If a check fails (for example, with an I/O error), the entrypoint does not write the marker, so the next boot checks again. - The entrypoint writes timestamped lines when it starts, around the full ownership check or any repair (with the duration), and just before it starts the server, so you can measure the pre-start time from the container log.
- Paperclip data persists via Docker volumes/bind mounts (compose) or at
~/.local/share/paperclip(quadlet).
Native Runner build cache
The image compiles the native Runner in runner-build, before copying the
application source. A pinned cargo-chef generates a dependency recipe in
runner-plan. The separate runner-deps stage compiles that recipe with the
package-owned Rust compiler. Both the dependency build and the real binary use
the release profile and locked Cargo dependencies. The recipe stage never
modifies source in the checkout.
Changes to Rust source or embedded protocol inputs rebuild the real binary but
can reuse compiled dependencies when the recipe is unchanged. Dependency
manifests, the Cargo lockfile, target metadata, or compiler changes invalidate
the relevant cache. Ordinary server or UI changes can reuse the entire native
build through the existing registry cache (mode=max). Each platform gets its
own native build; no cross-architecture binary is reused. No additional GitHub
Actions cache is created. A cold build also installs the recipe generator and
compiles dependencies, so the savings apply after those layers are available.
Cloud builds import one registry cache: the first available full-SHA cache in
the current commit's ten-entry first-parent ancestry, with the legacy cache
as a final fallback. Each build still exports its own SHA cache with
mode=max. In fresh-builder checks, importing several historical manifests
missed native layers that a single matching manifest reused. The selector
inspects metadata after Docker login, stops at the first available cache, and
permits a cold build if no cache can be read.
The application build inherits that stage and still runs the normal server build, including Cargo, binary staging, and generated-contract checks. Rust input file times are normalized in both stages so fresh checkouts do not force Cargo to rebuild unchanged source. Changes made by build scripts still reach Cargo's normal validation. The final application copy excludes Cargo's target directory as before. Cache misses only cost compilation time.
Pull requests that change the Dockerfile, Docker ignore rules, or Runner native
inputs also build the isolated runner-build target in Docker Runner check.
The check runs bash scripts/check-docker-runner-cache.sh against a disposable
copy of tracked source and the actual Docker ignore rules. It compiles a baseline
and exports a local cache, removes that builder, changes a Rust metadata constant,
and rebuilds on a fresh builder using only the exported cache. It requires a
cached dependency build, an unchanged dependency recipe, and changed metadata
from the real binary. It also verifies that a dependency declaration change
alters the recipe. The probe exports small metadata results instead of importing
a large test image into the Docker daemon. Temporary builders and cache files
are removed afterward. It catches missing embedded inputs before the post-merge
build. It uses a GitHub-hosted runner with read-only repository access and never
publishes images or registry caches. Allow up to 20 minutes for its cold build and
source rebuild.
